Good news: you don't have to leave your Tello service behind when you travel. Whether you want to use your actual phone line abroad or just stick to Wi-Fi, you have three solid options to stay connected.

All phones purchased from Tello are already unlocked so no international unlock is required for use overseas.
If you came to Tello with a locked device then you will need to get the device unlocked with the original carrier.
Tello does not lock or unlock devices.

Option 1: International Roaming
You can use Tello roaming in over 200 countries. This uses cellular towers abroad and pulls from a Pay As You Go balance.

• How to activate: Log in to your Tello account, go to "My Settings," and flip the "International Roaming" switch. To use Data while on Roaming, enable the option "Pas As You Go Data".
• Cost: You’ll need at least a $5 Pay As You Go credit to turn this on. Calls, texts, and data will be deducted from that balance.

Option 2: Wi-Fi Calling & Text
This feauture lets you use any local Wi-Fi (hotel, cafe, or hotspot) to make calls and send texts just like you’re back in the States.
The Benefit: It doesn’t cost extra—it just uses the minutes from your existing Tello plan.
See more details on this blog.

Option 3: The "My Tello" App
If your phone doesn't support built-in Wi-Fi calling, you can download our free app on iOS or Android.

• What it does: Allows you to make calls over Wi-Fi.
• The Catch: You cannot receive calls or send/receive texts through the app; it is for outgoing calls only.

To make a call, simply dial the destination number from the keypad (always include country code) or choose from your phone "Contacts" tab (ensure the number is in international format).
