How can I use Wi-Fi Calling?

Wi-Fi Calling & Text is included with your Tello service.
This feature is available on the vast majority of Tello GSM-compatible phones and you can check your own phone settings to confirm. It allows for calling & texting via the closest available Wi-Fi network which could be at a hotel, your office, at home, or even a Wi-Fi hotspot.
It is an ideal alternative to Roaming (which we don't yet offer) when you are traveling abroad or even when you experience poor network coverage at home in the US.
You can use Wi-Fi Calling with Tello if the following conditions are met:
  • your device supports Wi-Fi Calling which the majority of Tello GSM-compatible phones do.
  • you have enabled Wi-Fi Calling on the device.
  • you have registered an E911 address in your Tello online account (or through your phone Menu).
  • the Wi-Fi network you are using allows Wi-Fi Calling. Obviously, this is not within Tello's control or responsibility.

How is Wi-Fi Calling & Texting Charged?
Wi-Fi Calling & Texting has no additional charge.
It's simply taken from your existing plan balance or your Pay As You Go balance, whichever applies to the activity.
For example, if you receive any calls (no matter where from) or if you call the US or any of the 60+ included international destinations then the minutes of those calls will be deducted from your minutes' plan balance.
If, on the other hand, you call an international destination that is not included in our plans (Ex: Cuba), then it will be charged from your Pay As You Go balance if you have one.
The same logic applies to Wi-Fi Text.

One-Time Passwords (OTPs)
You can receive any kind of text message if you have successfully set up WiFi calling & text.
This includes, one-time passwords (OTPs) and shortcodes for verification and 2-factor authentication.
If Wi-Fi calling & text is working for you while abroad and you’re receiving SMS's as usual, there should be no problem for you to get texts from your bank for verification.
However, of course, MMS will not work.

Please check our International Calling page for included countries and the rates for excluded countries.
Also, please visit our Blog for more details about Wi-Fi Calling & Text.
