Phone signal keeps dropping: causes and fixes

A signal that keeps dropping can be caused by coverage where you are, the SIM card, the phone’s settings or a fault in the antenna or network hardware. The steps below help you tell whether the problem is the phone or the line.

Cep Market Repair TeamIn Kadıköy since 2006
Key points
  • If other phones also lose signal in the same place, coverage is most likely the cause.
  • Remove and clean the SIM card and try it in another phone.
  • Resetting network settings does not delete your data.
  • Thick cases or cases with metal can weaken the signal.
  • Signal problems after a drop or liquid contact need an antenna check.

01Why does the signal drop?

  • Coverage. Signal weakens indoors, in basements or in busy areas.
  • SIM card. A worn, dirty or loose card breaks the connection.
  • Settings. Network mode, operator selection or settings after an update can play a part.
  • Case. Cases with metal or very thick cases can cover the antenna.
  • Hardware. An antenna cable, SIM reader or baseband chip fault.

02Step-by-step fix

  1. Compare with another phone. Check another phone on the same carrier in the same place.
  2. Toggle airplane mode and restart the phone.
  3. Check the SIM card. Remove it, wipe it with a clean cloth, reinsert it fully and try it in another phone.
  4. Select the operator automatically. In mobile network settings, check that the network operator is chosen automatically.
  5. Reset network settings. Your data is not deleted; Wi-Fi passwords are reset.
  6. Update the software.
  7. Test without the case.

FAQ

Frequently asked questions

01

If the signal keeps dropping, is the phone at fault?

Not always. If other phones nearby have the same problem, it is coverage; if the SIM works fine in another phone, the phone should be checked.

02

Does resetting network settings delete my data?

No. Saved Wi-Fi networks and Bluetooth pairings may be reset; your photos and apps are not touched.

03

Can a case affect the signal?

Cases with metal or very thick cases can cover the antenna and weaken the signal. Test without the case.

04

Can a new SIM card fix signal problems?

If the old SIM card is worn or damaged, yes. Get a new SIM from your carrier and try; if it does not help, the phone’s antenna or board should be checked.

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.
