SIM card inserted but it says “No Service”: SIM or phone?

If the phone says “No Service” with a SIM card inserted, first find out whether the SIM or the phone is at fault: try the SIM in another phone and another SIM in this phone. If the SIM works elsewhere, the cause may be the phone’s SIM tray, antenna or network chip.

Cep Market Repair TeamIn Kadıköy since 2006
Key points
  • First try the SIM card in another phone.
  • Toggling airplane mode and restarting often helps.
  • Clean the SIM and tray and seat the card flat.
  • A suspended line can show “No Service”; ask your operator.
  • If the phone is at fault, the tray, antenna or chip is checked.

02What you can try at home

  1. Airplane mode. Turn airplane mode on and off after a few seconds.
  2. Restart. Turn the phone off and on.
  3. Reseat the SIM. Clean the card and tray with a dry, soft cloth; insert the card flat and the right way round.
  4. Ask your operator. If the line is suspended or the card is old, the operator can issue a new SIM.
  5. Reset network settings. Saved Wi-Fi passwords are deleted; note them first.

03If the phone is at fault

If the SIM works in another phone but yours still shows “No Service”, the cause is usually the SIM tray (card reader), the antenna connection or the network chip. Drops and liquid can affect these parts. Diagnosis is free; repair options are explained and nothing is done without your approval. If the SIM is recognised but there is still no network, see the operator and IMEI checks in SIM detected but no network. If the signal comes and goes, see phone signal keeps dropping.

FAQ

Frequently asked questions

01

Why does it say “No Service” with a SIM inserted?

It can be the SIM card, the line status, the SIM tray, the antenna or the network chip. Trying the SIM in another phone tells them apart.

02

Can a SIM card fail?

Yes, a worn or scratched card may not be read. Your operator can issue a new SIM.

03

Does resetting network settings delete data?

No; photos and apps stay. Saved Wi-Fi passwords and Bluetooth pairings are deleted.

04

Will a SIM tray repair delete my data?

Data is usually preserved during a repair; still, you need to back up your data before the repair starts (backups are the customer’s responsibility).

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.
