Switching your Tello service to a new device is quick and easy!
However, it is important to note that Tello does not support "Direct eSIM Transfer" (the built-in iPhone or Android feature that copies an eSIM from one phone to another).

Instead, you will simply generate a fresh eSIM for your new device. This process will not affect your phone number.

Step 1: Check Compatibility
Before you begin, ensure your new phone is ready:

• Carrier Unlocked: The new device must be fully unlocked.
• Compatibility Check: Verify your new phone’s IMEI on our Compatibility Checker.

Step 2: Prepare for the Switch
To ensure a smooth transition, make sure you have:

• Your Tello Account Security Pin
  *If you don't have your PIN, check the Security PIN help details
• A stable Wi-Fi connection on both your old and new devices.
• Access to your Tello account on a computer or your old phone.

Step 3: Generate Your New eSIM

• Log in to your Tello account and go to the "My SIM" section.
• Select the phone number you will move to the new device, and click on "ESIM," and follow the prompts.
• Once the new eSIM is generated, follow the installation instructions with your new device.

⚠️Important

• Immediate Swap: As soon as you generate the new eSIM, the eSIM on your old device will be deactivated. You will be without service until the new eSIM is fully installed.
• No Data Transfer: This process only moves your Tello phone service. It does not transfer your photos, text messages, contacts, or apps. You should use iCloud, Google Drive, or a device-to-device transfer tool for your personal files.
