Frequently Asked Questions

  • If you are new to Tello, you'll need to open a free account, build your own plan or buy Pay As You Go credit. Next, you’ll need to decide if you want to bring your own phone into Tello or buy a new one. Once your service is activated you can start making calls, texting or surfing the web.
  • Existing customers will be prompted via email & account alerts when their line is ready to migrate.
    We recommend that you prepare for migration by checking your current device for GSM device compatibility and check your location for GSM coverage.
    If both of those pass the checks then all you will need to do is order the free Tello GSM SIM when prompted to do so in your online account.
  • Nothing will change, except for a better-improved coverage offered by the 5G GSM network. Your plan's price, balance, phone number, or billing date are in no way affected by the migration. You will be able to enjoy the same super affordable phone plans & great Tello service.
  • All Tello Phones are compatible with the new Tello GSM network.
    If you buy a phone from us it comes with a Tello GSM SIM so no need to buy a new one.
  • Your phone will still work on Tello if it's a GSM VoLTE compatible device. A big chunk of our customer base already have devices that will be compatible with the new GSM network. You can easily check if your phone is compatible by entering your phone's IMEI code here.
  • You need to have a GSM SIM card in order to access the Tello network, to be able to place, receive calls & texts. The GSM SIM needs to be placed in the slot of your GSM device. You can purchase a GSM SIM card directly from us.

Switching from a landline that was way too expensive for our use of it. Sad to lose whole-house connectivity, but AT&T is simply out for money now.
