What is an eSIM? Why is it Better for Consumers?

iPhone eSIM

We talked about how eSIMS were going to be a game changer for customers last year. And our predictions were right it seems. Apple has added eSIMs into their latest phones, and they’ve been using that technology in watches since they launched the Series 3 in September last year. But what is an eSIM? Short for”embedded SIM” (also called eUICC), an eSIM is a digital SIM that allows you to activate a cellular plan from a carrier without having to use a physical SIM card.

Why would manufacturers Switch to eSIMs?

For phone manufacturers, there are two reasons why they’d want to switch to eSIMs.

1. Better design

Physical SIM cards are mostly useless plastic and the actual working part of the SIM is that tiny metal strip. Removing that tiny bit of plastic means that phone can be a tiny bit thinner.

Size comparison between mini, micro, nano and eSIMs

And as phones and devices get smaller and thinner each tiny little bit of space counts. There’s also the housing, reader, and tray that are needed with physical SIM cards. Manufacturers can eke out a bit more space as well. Plus, removing slots and openings from any device’s shell make it less likely to be compromised by water or dust.

2. Better experience for device owners

In Apple’s case, they decided to use all that extra space to add Dual SIM options to their options. This allows them to deliver a much better experience for their customers.

Here’s why eSIMs are better for consumers:

Picking secondary carrier with an eSIM

1. You’ll be able to change carriers without having to get a new SIM. You can change carriers or your plan in your phone settings. This means less time speaking with carriers, and ordering and waiting for new SIMs. Software does everything.

2. No more having to deal with cutting SIM cards, or finding adapters

3. With eSIMs and dual SIMS, you can have two plans from two different carriers. This means you can:

  • Use one number for business and another number for personal calls.
  • Add a local data plan when you travel outside of the country or region.
  • Have separate voice, text and data plans.

With that being said, if you need a second number with a more basic plan, or want to buy talk, text or data separately you should take a look at some of our plans. They start at only $4/month.

Lost Service on Rok Mobile?

ROK Mobile seemingly abruptly stopped service on their CDMA network as confirmed by WhistleOut, Fierce Wireless, Best MVNO and others. This left many of their customers stranded without service.

If you’re a stranded Rok Mobile customer, here’s what you do?

  1. Don’t panic.
  2. If you want to keep using your phone you’ll need to find carriers that are compatible. Sites like Whistleout, and Best MVNO have recommendations. Our Super LTE network is also compatible.
  3. If you want to keep your phone number you’ll need to port out your number from Rok. You’ll need your account number and PIN from Rok. And, unless you’ve changed them, this is how you get it:
    • Account Number: Your ROK Mobile phone number
    • PIN Number: Last 4 digits of your ROK Mobile phone number
  4. Before you switch you should consider all the plan options there are available. You can check out US Mobile’s Unlimited Plans that offer more data for better prices. Plus, we’re offering all Rok Mobile customers that were stranded a free Starter Kit and 50% Off their first month. Just use the promo code ROK during checkout.

We’re sorry to hear that Rok Mobile is shuttering their services on that network, but we’re happy to help any of their customers who still need phone service on their devices with the

Does your Alarm Need a SIM Card? Look No Further!

SIM card for Alarm in Wireless Security System

We have recently seen an increase in demand for SIM cards for wireless alarms and home security systems. So, we launched a new page dedicated to SIM cards and plans for Wireless Alarm Systems! A wireless home security system is just one of many different types of connected devices using US Mobile’s SIM cards and plans.

Choose the Right Plan for Your Alarm System

US Mobile’s customizable talk, text or data plans, make it easy and cheap for you to connect any device. Our monthly plans are so affordable that if you have a home security system only using texts messages, you would be paying $4 per month, including all fees. We know. That’s crazy. If you need data, just add it to your plan and pay $6 per month for 100 texts and 100 MB.

If for some reason you don’t want to keep the alarm connected for a particular month, you can downgrade and just pay a monthly fee of $2 to keep your SIM card active.

Most of you are probably worried about the opposite though! It is critical to have the alarm system running at all times. In order to ensure that, you also have the option to set your account to Auto Pay to avoid missing a payment. Remember that you can always log in to your account and see how much of your plan you’ve used with our real-time dashboard.

All Connected Devices are Welcome

US Mobile offers plans for any and all security systems and alarms that use SIM cards. If you have other connected devices in your home, or if you’re looking for a new wireless phone service, visit our Plans Page to see what you could be saving today.

3 Things You Should do Before Selling Your Old iPhone

New iPhones are coming out and they’re expensive. Spending all that money can be hard to justify, but if you must have the new iPhone you could recoup some of that money by selling your old iPhone, it might just be an easier pill to swallow. However, before you sell your phone to some random person you should wipe all personal data on your phone.
Deleting things to sell your iPhone

Back it up, back it up. Your old iPhone.

Not like J-Lo. But into iCloud. This will make sure that you have backups of all your photos in case something happens. And it will make setting up that brand new phone as easy as well pie. Here’s how you do that:

It’s easier if you’re already signed into iCloud. Your iPhone probably already has backups saved. You can check this in Settings> Yor profile>iCloud>iCloud backup and switching it on. If the iCloud backup wasn’t on, give the phone some time to upload all that data, and move on to the next step when the backup is complete.

Another quicker method is to back up your old phone using iTunes on a Mac or PC. Connect your iPhone to your device and switch on iTunes. Click the little iPhone icon on the top-left corner, and select Back Up Now. Give it a few minutes to complete the backup. When you connect your new phone to your computer, it’ll ask you if you want to restore from iTunes.

Delink your account from the phone.

You should sign out of your account so that it’s not linked anymore to any more of your profiles. This will also make sure that the person who bought your phone won’t have any problem activating anything, can’t access any of your profiles or services using the account on your phone. 

Go to Settings>Your Profile. Scroll all the way down, and Sign Out. Your account will be delinked from the phone, and now the new user can reactivate it with his account. You’ll also be signed out of all other services that use that profile, like iCloud, iTunes, App Store, Family Sharing and any other apps you may have set up. The new owner of the phone can’t use your account for anything now.

Note: If you’re getting a new number, you might want to delink your old number from iMessage as well.



After you’ve backed everything up, and signed out of all your accounts you can finally reset your phone. It is as oddly satisfying as it sounds. 

Luckily, with iPhones, you don’t have to worry about encrypting your data before deleting it. Every iPhone after the 3GS encrypts data automatically. Go to Settings > General > Reset > Erase All Content and Settings. And that’s it! When deleting all your data on your iPhones is finished, it will show you the welcome screen as if it were a brand new phone.

CDMA vs GSM vs LTE: The Differences & What You Need to Know

CDMA vs GSM vs LTE Labels

US Mobile provides service on the leading GSM, CDMA and LTE networks in the US. But what are GSM and CDMA, and how do they affect your phone, service, and coverage?

What is CDMA vs GSM vs LTE?

GSM and CDMA are different technologies that phones use to connect. They were both developed in the early nineties for 2G connectivity. But engineers couldn’t agree on which one was the best. So, in the US the FCC settled on a “dual-mode” route that required either GSM or CDMA. That’s why we have 2 different technologies.

Europeans though, agreed on GSM, as did the rest of the world. That’s why GSM is the de-facto system for the rest of the world.

For 3G, carriers only improved the original GSM and CDMA technology. So the duality remained.

Fortunately, engineers agreed on a new cellular system for 4G connectivity. And that’s LTE. Carriers designed LTE for data. But it’s been working so well that they replacing everything else with it. For example, they’ve introduced VoIP solutions like VoLTe to replace traditional calls.

Do all the carriers agreeing on LTE mean it will easier to switch phones between carriers?

You would think so. But, no.

Most new phones use LTE only for data and rely on GSM or CDMA for voice and texts. So you’re stuck with choosing between a CDMA and GSM phone if you want voice. However, most of Verizon and Sprint’s customers are on LTE. They’re working on VoLTE to solve the voice over CDMA problem so they can phase out 3G as early as 2019.

Moreover, the four carriers provide LTE on different frequency bands. They sell phones that only work on their frequencies, making it difficult to switch.

Many phone companies are also making phones that support CDMA, GSM, LTE on most bands. iPhones 6 and beyond, Google Pixels, Samsung S7s and beyond.

To find out if your phone is LTE enabled, check out this list or click on the brand below.

Apple   –   Samsung   –   Huawei   –   LG   –   Alcatel   –   HTC   –   Sony

What you NEED to know about CDMA vs. GSM vs LTE

Call Quality on CDMA vs GSM

Whether you use a CDMA or GSM network, it does not matter. What matters is the coverage from the CDMA and GSM networks. Luckily, US Mobile has excellent cellular coverage using the best GSM and CDMA networks in the US.

CDMA vs GSM phones

Switching GSM phones between different networks is easier than with CDMA phones. That’s because all GSM phones use removable SIM cards. You can put a SIM from one phone into a newer one and all your info like phone number and plan will go to the new phone.

CDMA phones didn’t use SIMs. They used embedded serial numbers to identify their users to carriers. This meant three things:

  • You couldn’t switch phones easily. You had to tell your carrier that you have a new phone so they can link the serial number of the new phone to your account.
  • This gives carriers more control over your phone choices. And, more often than not, they didn’t accept new phones unless you bought it through them.
  • Since there was no way to insert a SIM card you could not take your phone with you to a GSM carrier.

LTE phones need SIM cards. And, since LTE provides the fastest data most newer phones also have LTE capabilities. Thus, most newer phones also take SIM cards. Does that mean you can switch phones between carriers? It will be easier, but you still have to make sure your phone has the different frequency bands. Or buy phones that support CDMA, GSM and LTE on most bands.

Or find a carrier who provides service on GSM, CDMA, and LTE networks, lets you bring any phone and helps you figure out the best network for your phone (seriously just ask us and we’ll help), and provides great service and coverage with that 🙂

US Mobile’s Starter Kit Comes with a GSM and Super LTE SIM Card

Starter Kit GSM and LTE SIM

Why choose a SIM and a network when you can try both and choose whatever is best? This was the question that triggered the launch of  US Mobile’s Starter Kit.

US Mobile operates on the two best networks in the country and to access them, you need either a GSM SIM card or a Super LTE SIM Card. However, as a customer, it is difficult to know which SIM and network that will work best in your area. That’s why we decided to not make you choose, but rather send you both SIM cards so that you can try what works best for you. You get two SIM cards for the price of one, at $3.99. Feel free to do whatever you want with the SIM card you don’t choose to activate. We’ve heard that SIM cards make great gifts to friends or family members 😉

Ordering a Starter Kit at US Mobile

Getting started with us is super easy! Begin by ordering a SIM kit, containing a GSM and Super LTE SIM card. Then, you need to activate your prepaid SIM card and choose between 800+ plans. Yes – we know that’s a lot of plans to choose from but we really want you to find the plan that suits your individual needs. Finally, insert the SIM card into your phone and you’re good to go! We even include a SIM card ejector to make the switch as smooth as can be.

Ordering US Mobile SIM Cards

As always you can bring your phone, keep your number and we won’t hold you to any contracts. If you haven’t checked out our new Super LTE plans yet, we suggest you head over to our Plans page. The unlimited plans are unique on the US market since it lets you decide the data speed.

Need for (Data) Speed? Or Do You Prefer a Cheaper Data Plan?

Data Speed

The fastest animal in the world is the cheetah, reaching speeds of up to 61 miles per hour. (Btw this record was set by an 11-year-old cheetah called Sarah in 2012.) But faster isn’t always better, at least not when it comes to data speeds.

Faster speed = More Consumption

We’ve covered this before but the faster data speed, the more data you end up using. If you do the exact same thing, for instance, download a file with slow data vs fast data you’ll use the exact same amount. That’s, however, not the case when you use your phone in a habitual way.

By having a faster data plan, your phone will download elements faster when you’re browsing the internet or watching videos. Instead of downloading partial sites you visit, you end up automatically download all of the page, including all its widgets. Entire videos will also be buffered, even though you just watched parts of it. This means that a faster data speed equals an increased consumption of background data. In addition to automatic downloads, you might be tempted to stream at a higher quality if your data is fast. This also consumes more of your data plan.

Our Data Plans

Similar to how certain apps like Netflix and Spotify lets you adjust streaming quality, we let you adjust your data speed in our plans. As far as we’re aware, we’re the only one on the market offering unlimited plans at different data speeds. If you mostly use your phone for regular web browsing in checking mail, a Standard data plan should be sufficient. You get about 1 Mbps with the Standard plan and by not maximizing your data speed, you can save $20 per month.

Unlimited data plan

Further, a typical user might enjoy watching the occasional video clip, add stories to Instagram or snaps to Snapchat. If you’re that kind of user, you might be better off going with the Fast plan. The data speed is 5 Mbps, which means that you will have a smooth experience as you go about using your phone. If you’re a data hog, on the other hand, who enjoys watching a lot of moving content, go with the Ludicrous plan. The speed is uncapped, which means you’ll reach speeds of up to 150 Mbps.  That’s nothing but blazing fast!

By offering data plans at the different speeds, you get the freedom to choose what’s more important to you – maximizing speed or being frugal. It’s up to you!

Using a Mobile Hotspot

As you can see in the matrix, you also get the option to add a mobile hotspot to your plan. So what is a hotspot? If you turn on your cellular connection into a Wi-Fi connection, you’re able to access and use the data plan from other devices than your phone. This is called creating a hotspot, or a mobile hotspot to be more specific. It’s a great service if you’re not able to connect to an open Wi-Fi but you need to send an email on the go or if you’re working temporarily at a location that lacks an internet connection. When you connect your computer to your phone, it’s called tethering.

All our Super LTE Custom plans include the hotspot service.

iPhone X Offer: Get $200 Back When Joining US Mobile

iPhone X

On the third of November, the first lucky ones will have an iPhone X in their hands. And we want to be the carrier of choice for all you iPhone X users out there! This is why we are offering $200 back for anyone who brings their iPhone X to our new Super LTE network. Also, did we mention that we’re not locking you into a contract and you don’t even have to trade in your existing device?

US Mobile’s iPhone X Offer

Yesterday we launched our Super LTE network and plans which are perfect for the new iPhone. As our CEO and Founder Ahmed Khattak phrased it: “We have the best network and plans for the new iPhone X and we want to prove it”.

Therefore, all iPhone X users, who join our new network will get $200 back. No strings attached. The $200 will be divided over the first 6 months of service with US Mobile. Meaning, $33.34 will be refunded on each month’s service plan (not including taxes, fees, or top-ups).  So for example, a customer with a $40/month plan will receive a refund of $33.34 after the plan purchase is processed. Nevertheless, customers who are on a lower plan than $33.34, have gaps in service or leave US Mobile will forfeit their ability to claim the remainder of the refund. No cash back will be granted. The offer is limited to one per person, and it’s only available in the US.

To claim this offer, the only thing you need to do is to get a prepaid LTE SIM and activate it. Then fill out this simple form. We’ll take care of the rest! Unfortunately, this offer is now expired.

iPhone X Offer

Buying the iPhone X

We don’t currently sell the iPhone X in our shop. But you can pre-order it from other stores, e.g. Apple store, and bring it to US Mobile for wireless service on the new Super LTE network.  To be compatible with our network, you should bring an iPhone X that was sold with either Verizon or Sprint bands.

The overall response after testing the iPhone X is positive. According to various reviews, the Face ID is easy to set up and works well, even in pitch black and in weird angels. Another appreciated feature is the Apple Pay, which works very smoothly on the new phone. Basically, you just double tap the power button while looking at the phone. Then, you hold it up to the payment terminal and pay. According to testers, it’s much easier than older generation phones. Colorwise, it comes in a space gray and silver finish. The band around the phone is made of surgical-grade stainless steel for durability and sleek look. Finally, the price is $999 (without any type of discount).

Super LTE with Unlimited Plans and Special iPhone X Offer

Super LTE network

GSM SIM Card & Super LTE SIM Card

We’re beyond excited to not just launch our second network (which happens to be America’s biggest LTE network) but also Unlimited Plans and an exclusive iPhone X offer! It’s a good day to be a US Mobile customer, or become one 😉

The New 4G LTE Network

This summer we announced that we’ll be launching on a second network and we’re so happy that the day has finally come! We will, of course, keep our GSM network. By having both, customers will be able to choose which network that is the optimal for them depending on where they live, user habits etc. To separate them, we’re calling the new network “Super LTE”, and the GSM network will simply be “GSM”. This will also be reflected in the new LTE SIM card.

Unlimited Plans

As if a new network wasn’t enough, we also decided to launch a number of unlimited plans. We want to be able to serve any kind of user, no matter device, user habits or geographical area. If you’re a data hogs, you’ll enjoy several options of unlimited data plans:

  • Limited text and talk: Unlimited data + 100 min + 100 min, starting at just $35/month.
  • Unlimited everything: Unlimited talk, text, and data
  • Unlimited plus hotspot: Unlimited talk, text, and data including hotspot. Unlike many other hotspots, this will be uncapped like the data speed.

All plans come in three different speeds being Standard (1 Mbps), Fast (5 Mbps), and Ludicrous (up to 150 Mbps). That way you can choose if a blazingly fast data speed is more important to you than saving a few bucks every month.

LTE Unlimited PlansIf you don’t need unlimited data plans, we’ll also offer a plans matrix similar to the one we offer on the GSM network. The Super LTE customizable plans will have a welcome addition of a small bucket containing 40 minutes, for just $2.50 per month and 1GB will only cost $11 per month.LTE Customizable Plans

Super LTE and GSM Coverage

The Super LTE network is the biggest network in the country, which will be reflected in the coverage. In addition, the GSM network works best in urban areas with network ultra-fast data speeds in most cities. As always, coverage depends on where you are, and that’s why we have partnered with the two best networks in the US. So, no matter where you are you’ll get the best possible coverage with US Mobile.

New Features

The new network will share many of the features of the GSM network, like auto-pay and snooze functionality. Two new additions will be international calling and visual voicemail. The latter means, a voicemail with a visual interface. So instead of listening to your voicemails, you’ll able to read them and you can jump between different messages instead of sequential listening.

A third feature will be the ability to control data speeds as described above in the plans. By lower data speeds, the total data usage will be lower. Want to know more about how? Head over to Is Faster and Better Quality Network Eating More Data?


Compatible devices include all the mainstream Apple and Android phones, but less popular devices are not necessarily supported. Furthermore, the GSM network is compatible with the most devices of any network in the country. In order to find out if your device is compatible or not you can test your phone in our IMEI checker.

iPhone X Exclusive Offer

US Mobile wants to be the carrier of choice for all iPhone X users. Ahmed Khattak, CEO and Founder: “The iPhone X is the most anticipated phone in a decade, and that’s why we are offering $200 back for anyone who brings their iPhone X to our new Super LTE network and we won’t ask you to trade in your existing device. We have the best network and plans for the new iPhone X and we want to prove it”, said Khattak.

The offer is limited and only available in the United States. Maximum one per person when switching to US Mobile Super LTE. No contracts or credit checks required.

Q&A Prepaid Phone Plans – Reddit Asked and We Answered

Prepaid plans

Since the very beginning, US Mobile has offered prepaid phone plans. We believe that’s what gives our customer the most freedom and bang for their bucks. Still, there are a lot of questions lingering on what it is, if it’s better and how it works. That’s why we set out to do a Q&A on the topic.

In order to compile the most frequent questions, we did a thorough search on Reddit and here’s what Redditors want to know.

Is prepaid and Pay as You Go the same thing?

Not really, although they’re often used interchangeably. With prepaid plans, you pay in advance and once you’ve used up your plan you get disconnected from the service until you’ve bought another plan. If you Pay as You Go, you don’t buy a plan but rather minutes, texts, and data. Once you’ve used them, you can add more with physical or electronic refill cards.

Can I keep my number if I switch from postpaid to prepaid?

Yes, it doesn’t matter. You can port your number to the new provider.

My usage varies greatly – is postpaid or prepaid better?

This depends on whether you’re able to predict the variations or not. If you know when you that the next period will be lower, you can usually adjust prepaid plans in advance since you can regulate your plan month-to-month. If you have already paid for a larger plan in advance, and it turns out that your usage will be low, you can’t get that money back. Then it might be safer to buy a smaller plan, and top-up later in the month if needed. Postpaid, on the other hand, can be good if you don’t know how your usage will vary since you pay for what you have used. In order for this to work though, you shouldn’t be on an expensive base plan (like unlimited plans). Then it doesn’t matter how much you’ve used or not.

Postpaid, on the other hand, can be good if you don’t know how your usage will vary since you pay for what you have used. In order for this to work though, you shouldn’t be on an expensive base plan (like unlimited plans). Then it doesn’t matter how much you’ve used or not.

Do I need a Social Security number to get a prepaid phone plan?

No, no credit check or social security number is needed when signing up for a prepaid plan. Since you’re not in a contract, and you prepay for all your future usage, there is no reason for the carrier to get your background information. That’s also why prepaid plans are common for temporary or disposable phones.

Is it easy to cancel prepaid plans?

Having a prepaid phone plan means that you’re not under contract. That makes it easy to cancel at any time. What you need to keep in mind is how long you have prepaid for your plan before switching to another plan. Sometimes you prepay for 1 month, 3 months or even 12 months and once you’ve paid for a period, it tends to be hard to get out of. If you’re on a month-to-month plan, you have more flexibility. Just be mindful of the timing of the switch.

Can I get a discount on my device if I choose prepaid?

In rare occasions, you can get a discount on a device when joining a prepaid carrier. However, it’s a lot more common when you’re in a contract. The reason why postpaid carriers can give you discounted phones is that they know you’ll be a customer for at least 24 months, and they can earn the discounted amount back on the monthly service payments. That’s also one of the reasons why postpaid plans is usually more expensive than prepaid plans.

Can data rollover if you’re on a prepaid plan?

Rollover means that data, talk and/or text roll over from one billing cycle to the next if it hasn’t been used. And the answer is that it doesn’t matter if you’re paying for your plan in advance or at the end of the cycle. Every carrier chooses if they want to allow rollover or not. At US Mobile, all addons rollover for a separate cycle of 30 days, not following the base plan’s cycle.

Do I get the same downloading speeds as when I’m in a contract?

Throttling, which means intentionally slowing down data speeds, is a sensitive topic among carriers. Most carriers clearly state that they’ll start deprioritizing a user’s data speeds after they’ve used a certain amount of data in one billing cycle. The cap is usually between 20 Gb and 50 Gb. Now, some carriers do offer prepaid plans at a lower data speed than their postpaid plan. However, unless it’s clearly stated, the prepaid plans should have the same downloading speeds as postpaid plans. Head over to Rootmetrics if you want to learn more about individual carrier’s speeds.

How Do eSIMs work for prepaid carriers?

eSIM is a fairly new phenomenon and not implemented across the industry. eSIM is a standardized SIM chip open to multiple mobile carriers, instead of one specific carrier. To begin with, only selected carriers will support eSIM. It will also probably take a long time before all phone manufacturers will scrap the traditional SIM card slot. Prepaid or postpaid won’t matter in this sense, as it will be carrier-related if eSIM will be supported or not.
