AT&T MVNO FAQs

How do I switch to a AT&T SIM card plan?

Switching to a AT&T MVNO is smart, quick and simple. You don't have to buy a new device, since you can bring your own phone to the new carrier and you can keep your old number. All you need to do is order a prepaid SIM card and once you have that, you can switch your phone service in as little as 2-3 minutes.

Does AT&T have network coverage in my area?

All AT&T MVNO's are powered by the AT&T network. This means you'll receive exactly the same nationwide 4G LTE coverage that you would if you bought a plan from AT&T directly.

Can I keep my phone number when I switch to a AT&T SIM card plan?

Yes! It's easy to port your existing phone number to a AT&T during the activation process.

Will a AT&T SIM card plan work with my phone?

Yes! Most unlocked smartphones that have a SIM card slot will work with your new AT&T SIM card plan. If your phone is locked to a carrier you will need to contact your existing carrier to get it unlocked.
