Gsm Cell Phone Plans FAQs

How do I switch to a gsm cell phone plan with another carrier?

Switching to an 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.

Do these gsm cell phone plans have network coverage in my area?

All MVNO's are powered by at least one of the big 4's networks. In our comparison list of gsm cell phone plan we display the network options available with each plan. For example, if the plan says 'powered by Verizon', it means the carrier operates on the Verizon network and you'll receive exactly the same nationwide 4G LTE coverage that you would if you bought a plan from Verizon directly.

Can I keep my phone number when I switch to a new gsm cell phone plan?

Yes! It's easy to port your existing phone number to another carrier during the activation process.

Will a gsm cell phone plan with any carrier work with my phone?

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