  • Much lower prices: Save up to $600 a year per line whether you've got plans for 2 lines or plans for 5 lines. Why are MVNOs so much cheaper? They usually don't have physical stores so their costs are lower. They then pass those savings on to you.
  • No contracts: No more two year commitments. Switch carriers when you decide to with a no contract phone plan.

Switch to a cheap AT&T unlimited plan

Making the switch is much simpler than you might think.

  1. Customize your plan. Pick the features and options you need so you only pay for what you'll use. Even if you need plans for 4 lines you can customize each one to fit just right.
  2. Prepare for the switch. Make sure your current account is paid up and your phone is unlocked for use on another carrier.
  3. Set up your new plan. Don't cancel your old account until your new one is active or you could lose your phone number. You'll get a SIM card kit from your new carrier if you're not buying a device from them. Just pop it in and follow their instructions to activate your service.

Bring your own AT&T phone

Switching carriers really can be hassle-free. Plus you can usually bring your own AT&T phone to the new carrier. Once you've determined that AT&T has the best coverage in your area you can just follow these simple steps:

  1. Choose a carrier. Pick the AT&T MVNO with the best unlimited data plan to fit your needs and budget.
  2. Pick a plan. Check out our data usage calculator to see if you actually need unlimited data. Then choose the plan that works best for you. Most people actually only use about 3 - 5GB of mobile data per month.
  3. Check phone compatibility. AT&T and T-Mobile phones should both work on AT&T MVNOs. Many other devices are also compatible though. We recommend always checking with your carrier first.
