Some phones use a physical SIM card (pSIM), while others use an embedded SIM (eSIM), which is a digital version downloaded to the phone. SIM cards let you connect your phone to the Xfinity Mobile network so you can make calls, send messages, and more. Don't worry if you see one of these error messages:
Don't panic if you see one of the following error messages:
- "No SIM."
- "Insert SIM card."
- "SOS."
Sometimes, the pSIM just needs repositioning or cleaning. For an eSIM, it might have been accidentally deleted. Here's how to inspect and clean your pSIM card and steps to replace your eSIM if it's been deleted.
Inspecting and cleaning your pSIM card
- Turn off your phone.
- Remove the SIM card tray using your SIM ejector tool or a paperclip. Take out the pSIM card.
- To find out exactly where the tray is located on your phone, see support for your device:
- Look for dust or dirt on the gold contacts.
- Use a soft cloth to gently clean the gold contacts.
- Put the pSIM card back into the tray, chip-side down, and insert it into your phone.
- Restart your phone.
If you’ve cleaned and reinserted the pSIM and it still isn’t working, contact us. We can help you figure it out and send you a replacement SIM card if needed.
Ineligible device
Did you move your pSIM card to another device and now can't make phone calls? It might be because the new device is ineligible for use on our network. Common reasons include:
- The device was reported lost or stolen.
- The device was meant for Prepaid service.
- The device has an outstanding balance with your previous provider.
- The device isn’t certified for use on our network.
If your device fits one of these categories, your service will be temporarily suspended.
