Flight mode light blue no network

[puzh2start]

Hi guys anyone that knows how to solve this issue. I have an A52 .Flight mode is slightly blue and I have no network , I'm unable to select network manually when I try to switch it on network operators it says error while searching.

When I remove sim card flight mode goes completely off and the minute I place it back flight mode goes light blue. My sim card works fine on other device.

Try opening the Galaxy store and search for "Carrier services". Update the app if an update is available.. This app helps your phone connect to carriers network.

Check SIM Card & Slot

Clean the SIM card and slot with a dry cloth.

Try your SIM in the second SIM slot (if available).

Boot into Safe Mode (to check for app interference)

1. Press and hold the Power button


2. Tap and hold "Power off", then select Safe mode


3. Check if Airplane Mode behaves normally


4. If it works in Safe Mode, a third-party app may be causing the issue. Uninstall recently installed apps.

Check for SIM Lock or IMEI Issues

Dial *#06# and check if your IMEI number appears.

If IMEI is missing or shows Null, your phone might have a firmware issue or be blacklisted.
