Activating your Tello plan

Once you've chosen your Tello plan, activating your SIM card only takes a few minutes. Below, I'll guide you through the activation steps for both Android and iPhone devices:

How to set up a Tello SIM card:

Follow these steps to activate your physical Tello SIM card:

  • Go to MySIM in your Tello account.
  • Follow the prompts until your activation is confirmed.
  • Insert your SIM card into your device and turn it on.
  • Follow the instructions on your phone screen.

If you bring your own phone, you may need to take a minute to configure some settings to optimize your phone service.

Follow these steps, depending on your phone's operating system:

Tello iPhone setup:

On an iOS device, you can view or adjust your APN settings in one of the following locations:

  • Settings > Cellular > Cellular Data Options > Cellular Network


  • Settings > Mobile Data > Mobile Data Options > Mobile Data Network.

Tello Android setup:

  • Go to Settings.
  • Tap More networks (under Connections, or More, Wireless & Networks, Wireless Controls, Wireless Manager, Phone Information).
  • Select Mobile or Cellular networks.
  • Select Access Point Names.
  • Tap the Menu icon.
  • Tap the Access Point you want to check.
  • If you're adding a new APN, tap New APN.

Now all you need to do is use our handy Tello APN settings to plug the relevant information into your device.

Tello network issues

Encountering network glitches? No need to panic; try one of these easy fixes:

  1. Turn your phone off and on: There's a reason this method is so commonly recommended - it often works. Turn your phone off and back on, or toggle airplane mode on and off.
  2. Reinsert the SIM card: For those with a physical SIM, this step might help resolve issues. If you're using an eSIM, toggle it off and then on again.
  3. Software update check: I know system updates take extra time; the good news is that installing the latest version can fix various issues.
  4. Upgrade your phone or plan: If your device has seen better days, it might be time for a newer model. Old phones may cause compatibility issues.
