Do not retry repeatedly. Check three things first: your internet connection, free profile slots on the device, and whether this profile was already installed. Then contact us with the exact on-screen message.

- Open the plan list in cellular settings: is it already there, or are the slots full?
- Restart the device and try once more
- If it still fails, send us the order number, device model and the message shown
