Network problem

[Avi2223P]

The Network of the Galaxy M35 5G is really weak. It always disconnects with the wifi between 2 rooms. And the Sim netwrok is also weak. It can not send sms verification for Gpay from inside my room, I had to go out in open area to send that sms.

Can anyone has any solution for this?

1. Wi-Fi Keeps Disconnecting Between Rooms
Causes: Aggressive battery saving or weak antenna calibration.
Fixes:

Go to Settings > Wi-Fi > [Your Network] > Tap Gear Icon > Advanced
→ Turn OFF “Switch to mobile data” & Enable “Wi-Fi always on during sleep”.

Turn OFF Battery saver mode during Wi-Fi use.

Try resetting network settings:
Settings > General management > Reset > Reset network settings.

2. Weak SIM Signal & SMS Not Sending Indoors
Fixes:

Settings > Connections > Mobile networks > Network mode → Set to 5G/LTE/3G/2G (auto).

SIM tray issue? Gently clean and reinsert the SIM.

If dual SIM, try using the other slot.

Enable Wi-Fi Calling if supported:
Settings > Connections > Wi-Fi Calling → ON. Helps with SMS/Calls indoors.

⚡ Bonus Tip:
Check Samsung Members app > Diagnostics > Mobile network & Wi-Fi to test hardware. If weak, visit service center—antenna module might need inspection.

Try using the 2.4GHz band instead of 5GHz (2.4GHz has better range).
