iPhone not reading the SIM card: how to fix “No SIM”

If your iPhone does not read the SIM card, take out the tray, wipe the card, refit it and restart the phone. If another SIM card is not read either, the problem is the phone: the SIM slot or the cellular section should be checked.

Key points
  • Take out the SIM tray, wipe the card with a dry cloth and refit it.
  • Try another SIM card; if it fails too, the phone is the problem.
  • Open Settings › General › About; install any carrier settings update.
  • Resetting network settings does not touch your data.
  • If it started after a drop, the SIM slot or board should be checked.

01Step-by-step fix

  1. Refit the SIM. Take out the tray, wipe the card and make sure it sits flat.
  2. Restart. Turn the phone off and on.
  3. Carrier settings. Open Settings › General › About; accept the update prompt if one appears.
  4. Reset network settings. Settings › General › Transfer or Reset › Reset › Reset Network Settings.
  5. Try another SIM. If another card works, your old SIM is the problem.

Menu names vary by iOS version.

FAQ

Frequently asked questions

01

Why does my iPhone say No SIM?

A SIM not seated, a damaged SIM, carrier settings or a fault in the SIM slot or cellular section are the most common causes.

02

Does resetting network settings delete my data?

No. Only saved Wi-Fi networks, passwords and Bluetooth pairings are removed.

03

Will a SIM slot repair delete my data?

If the storage is intact, your data is usually still there; we confirm it at diagnosis.

04

Could my old SIM card be faulty?

It could. Get a new SIM from your carrier and try; if it works, the old card was the problem.

Phone works but the screen is black: what to do

If your phone rings or vibrates but the screen is black, the phone is on; the problem is the screen or its connection. Force restart and charge it first. Shine a torch close to the screen in the dark: a faint picture means a backlight fault. If it started after a drop or liquid, the screen is usually replaced.
