Does Tello offer Wi-Fi calling?


Yes! If your phone supports Wi-Fi calling, you can connect to a nearby Wi-Fi network and use the minutes from your Tello calling and texting plan.


You can also make calls (but not receive calls) through the My Tello app. Be sure you’re connected to Wi-Fi before using this app when you’re travelling, because it will use about 1 MB/minute otherwise.
