Free eSIM Trial for iPhone (2026)

Free eSIM trial for iPhone: what you get

Apple went all-in on eSIM with the iPhone 14, and every iPhone since then in the US has no SIM tray at all. That sounds limiting. It isn’t. It means you can activate a new carrier instantly, with nothing to insert and no waiting for mail.

Here’s exactly what the trial includes:

• 30GB of premium 5G data (full 5G, including mmWave and C-band)
• Unlimited talk and text to any US number
• 5GB of dedicated hotspot data to share with other devices
• 30 days to use it, with instant activation over Wi-Fi from your iPhone’s eSIM settings
• The option to keep your existing line running while you test US Mobile as a second eSIM

One thing to be clear about up front. You’ll add a payment method and transfer (port) an existing number to start the trial, but you aren’t charged anything during the 30 days. No contract either. If you don’t upgrade to a paid plan, the eSIM profile simply stops working. Curious how the offer compares across devices? Here’s the rundown of the US Mobile free eSIM trial in general, and our guide on how to activate an eSIM on any phone.

Which iPhones support eSIM?

Short version: if your iPhone is from 2018 or later, you’re good. eSIM support goes all the way back to the iPhone XS, XS Max, and XR. Here’s the breakdown.

The takeaway: released in 2018 or later, and your iPhone can run the trial. For the deeper technical specs, Apple keeps a full eSIM support page per model.

Running the trial alongside your current carrier (dual eSIM)

One of the smartest things about modern iPhones is that they hold two eSIM profiles at once. So you can keep your existing carrier line exactly as it is, and run the US Mobile trial as a completely separate second line. No risk to your current service while you test.

1. Activate the trial

   Set up your US Mobile eSIM trial using the steps below.

2. Open your plans

   Go to Settings > Cellular > Cellular Plans. Both lines show up here.

3. Label each line

   Name them so you can tell them apart (“Personal” and “Trial” works fine).

4. Pick your defaults

   Set Default Voice Line and Default Data Line. Use the trial for everything, or just for data while your primary carrier keeps calls and texts.

If you love the speeds and coverage, you can port your number over. If it’s not for you, delete the eSIM profile and you’re back to where you started.

How to activate the free eSIM trial on iPhone

The whole thing runs over Wi-Fi and takes about two minutes to install.

1. Start at get-started

   Go to usmobile.com/get-started and create an account or log in.

2. Add a new line, then Special Offers

   Choose “Free Trial” and continue.

3. Pick eSIM activation

   Skip the physical Starter Kit and select eSIM so there’s nothing to wait for in the mail.

4. Choose your network

   Select Warp or Dark Star. You get access to all three of US Mobile’s nationwide networks on paid plans; the trial runs on these two.

5. Transfer your number and activate

   The trial asks you to bring your existing number over. Confirm, then scan the QR code with your iPhone camera. Your line is live in a few minutes.

Tips for getting the best 5G speeds on iPhone

The trial includes full 5G, including mmWave and C-band. A few settings make sure you’re actually getting it:

• Turn on 5G in Settings > Cellular > Cellular Data Options, and confirm 5G is enabled.
• Enable “Allow More Data on 5G” so your phone prioritizes 5G for all data, not just streaming.
• In a major city? Watch for the 5G+ (or 5G UW/UC) indicator at the top of your screen. That’s mmWave, the fastest flavor.
• Run a speed test to benchmark your connection. On mmWave, 400+ Mbps is normal.

What to do after the trial

The trial is genuinely no-strings-attached. When the 30 days are up (or you’ve used the 30GB), you decide what happens.

1. Keep the service

   Liked the speeds? Stay on a paid plan. Light users start at $8/mo; Unlimited Starter is $25/mo (less on annual billing), all with eSIM, no activation fee, and no contract.

2. Port your number

   Move your existing number to US Mobile. The port usually wraps up in about 15 minutes.

3. Delete and move on

   Changed your mind? Settings > Cellular > Cellular Plans, tap the trial line, remove it. Your iPhone forgets the profile and you’re back to your original carrier.
