Short answer: AT&T is a GSM network carrier and works with GSM cell phones.

GSM stands for Global System for Mobile Communications. GSM and CDMA are the 2 types of networks that cell phone carriers use to provide your service.

In the past, you couldn't use a CDMA network's phone on the GSM network and vice versa. However, most newer smartphones can operate on either type of service.

AT&T GSM network carriers

If you're shopping around for a new carrier on the GSM network, consider MVNOs - Mobile Virtual Network Operators.

These smaller mobile providers rent space on the same networks the big guys use and then sell it to you at a lower price.

There are plenty of great AT&T MVNOs to choose from, such as PureTalk, h20 Wireless, and Red Pocket, which means you can get AT&T service without paying AT&T prices.


AT&T GSM carrier benefits

  • Get the same great service: You get cell phone service on the very same AT&T network.
  • Save over half: MVNO plans typically save you 50% or more over the big three carriers, including the AT&T GSM network.
  • Custom plans: Only pay for what you actually need and use.
  • No contracts or credit checks: No commitment and everyone is welcome!
  • Keep your phone: Most MVNOs are BYOP (bring your own phone) - keep your device and your number.

Bring your unlocked GSM phone

You need simplicity in your life. The great thing about MVNOs is that switching carriers is easy.

You need an unlocked phone (your carrier has released it on another network). Once you've checked with your new provider about phone compatibility, the rest is a breeze.

Most low-cost carriers simply provide you with a prepaid SIM card. You pop it into your cell phone and follow the provider's instructions. Just make sure you don't cancel your current phone plan until you've ported your phone number over to the new carrier.

How to switch to an AT&T GSM carrier

It's never been easier to switch. Let's break it down.

  1. Customize your plan. Whether you're looking for a truly unlimited plan or are in the market for something more basic, choose a GSM network plan to suit your cell phone needs.
  2. Prepare to make the switch. Ensure your old bills are paid and your phone is unlocked. If you're getting a new device, transferring data from one to another is simple, even if you're going from an iPhone to an Android and vice versa.
  3. Set up your new plan. You'll receive a guide to activate your plan with eSIM or a new SIM card kit in the mail. Keep your current carrier account open until your number has been ported. Once you're sure your new plan is up and running, cancel your old account.
