iOS 17 Activation

  • QR Code Method: Go to Settings > Cellular > Add eSIM. Point your camera at the QR code. Follow the screen prompts to finish.

Dual-SIM & Roaming Rules Want to keep your home number active for calls? No problem! Keep your primary SIM turned on. But make sure you set your new Celitech eSIM as your only line for Mobile Data. Turn Data Roaming OFF on your home SIM to avoid surprise fees. Then, turn Data Roaming ON for your new eSIM so it connects smoothly to international networks.

  6. Tap Continue to install the profile.

Step-by-Step for Android 14

Mastering Dual-SIM and Roaming

Managing two lines is a breeze.

  • Label your lines: Call your home SIM "Primary" and your new eSIM "Travel".
  • Default Data: Go to your cellular or network settings. Choose the "Travel" line for cellular data.
  • Data Roaming: Select your travel eSIM and toggle Data Roaming ON. Make sure Data Roaming remains OFF on your primary line.
  • Disable Data Switching: On iOS, make sure "Allow Cellular Data Switching" is turned off. This prevents your phone from sneaking back to your expensive home network for data.

Checking Your APN Settings

If your data refuses to work abroad, you might need a manual APN tweak.

  • iOS 17: Go to Settings > Cellular. Tap your eSIM. Select Cellular Data Network. Type the required APN into the Cellular Data field.
  • Android 14: Go to Settings > Network & internet > SIMs. Tap your eSIM. Scroll down to Access Point Names. Add a new APN with the provided details and save it.

Troubleshooting Tree

Got a frustrated traveler on the line? Use this troubleshooting tree to fix their problem fast.

Issue 1: Customer sees "Unable to Complete Cellular Plan Change"

  • Cause: Poor internet connection during setup.
  • Fix: Tell the customer to connect to a strong Wi-Fi network and try the install again.

Issue 2: Customer sees "Code no longer valid" or "eSIM cannot be added"

  • Cause: The eSIM is already installed. QR codes only work once.
  • Fix: Have them check their cellular settings. Look for an unnamed or unlabeled secondary line. Ask them to toggle it on and enable Data Roaming.

Issue 3: Customer reports a "PDP Authentication Failure"

  • Cause: Network connection glitch.
  • Fix: Ask the customer to turn Airplane Mode on for ten seconds. Turn it off and wait two minutes. If that fails, restart the phone completely.

Issue 4: The eSIM shows active, but there is no internet.

  • Cause: Incorrect roaming or APN setup.
  • Fix: First, verify Data Roaming is ON for the eSIM line. Next, ensure the eSIM is the designated line for Mobile Data. If it still fails, help them add the APN manually.

Macro 1: Fixing the "Code No Longer Valid" Error

Hey there!

Seeing that "code no longer valid" message usually means your eSIM is already safe and sound on your phone. The QR code only works once.

Please go to your phone settings. Under your Cellular or Network settings, look for a new secondary line. It might lack a custom name. Tap it, turn it on, and make sure Data Roaming is enabled!

Macro 2: Fixing "PDP Authentication Failure"

Hello!

Let's get that data working for you. A "PDP Authentication Failure" means your phone needs a tiny push to connect to the local network.

Try toggling Airplane Mode on for ten seconds, then turn it off. Give it a minute to find the signal. If that fails, please restart your phone completely.
