- Enable and disable Airplane mode. First, go to iPhone Settings or the Control Center and turn on Airplane mode. After waiting for about 15 seconds, please turn it off.
- Turn on the SIM line. If you use two SIM cards and it shows No SIM, go to iPhone Settings > Cellular > tap a SIM and enable the switch for Turn On This Line.
- Restart your iPhone. Often, the most frustrating problems are fixed by a simple restart. If you’re getting SIM card errors on your iPhone, turn it off and after waiting for a minute, turn it back on.
- Gently wipe and reinsert the SIM card. Sometimes after restarting my four-year-old iPhone, I would get the SIM Not Valid or No SIM Card message even though a functioning card is inserted.
Reinsert the tray and retest. Try the SIM from a friend or family member with the same cellular carrier. If it works, replace your SIM card. You can request one from your service provider, or visit one of their physical locations. As a workaround, use your phone’s eSIM instead.
