Eligible new customers will receive a 50-day free trial when transferring their phone number to our Warp 5G network.

All trial lines will be set up to renew on our Unlimited Essentials plan, which can be changed anytime up to two days before the trial period ends. Click here to get started!

Switching to US Mobile's plans is quick and simple. You don't have to buy a new phone, since you can bring your device to US Mobile. You can keep your old number. All you really need to get is our prepaid SIM Starter Kit or an eSIM capable phone. Once you have that you can switch your phone service to US Mobile in as little as 2-3 minutes. See how easy it is to switch to US Mobile.

We provide LTE coverage on the two fastest networks in the US. You can read more about our networks, and coverage here. Or you can just ask us!

All new US Mobile customers who transfer an existing number to our Warp 5G network are eligible. All you need is a new account, your preferred method of activation, and your device.

US Mobile is a prepaid, no contract carrier. This means that you pay for a 30 day plan when your plan starts. Not afterwards. If you are not on an unlimited plan, and run low on data, talk or text you can recharge your balance with Top Ups. You can also switch on AutoPay to have us automatically renew your plan every 30 days.

How Top-ups work varies by plan. If you are on one of our Unlimited plans, you will not need to top up. If you have lines on our Shareable Data plan, each line gets unlimited talk and text. If you run low on data in the middle of your 30-day cycle, you can just add additional GBs of data – as little as 1 GB, or as much as you want – as a top up mid-cycle for just $2/GB via the US Mobile app or via your US Mobile dashboard in a browser. These top-ups do not currently roll over.

If you are on one of our legacy plans (our custom plans or an individual bundle), you can top your talk, text or data balance if you are running low in the middle of your 30-day plan. For these plans, you can do top up through our app, the dashboard in a browser, or even with SMS, pick exactly how much you want and get access immediately. Top-ups on these plans roll over*.

Currently, you can make unlimited international calls to 88 countries on our GSM 5G network (whether you are on one of our Unlimited plans or our Shareable Data plan). If you are using our Warp 5G network, you can text abroad to most countries from the US and make calls to Canada at no extra cost to you. International calling to other countries will be coming to our Warp 5G network before the end of 2023. Note that international calling only works on our domestic (US) SIMs; if you have purchased one of our international data eSIMs, those do not support calling.
