I use Unicom card for my mobile phone, the signal is not good, and the Internet access is too slow. Which access point is the best?

If your cell phone signal is unstable or bad, I suggest you:

1. It may be that the signal coverage of your location is poor. I suggest you restart your phone or try another location.

2. Turn off the phone, take out the SIM card, and rub the SIM card chip with an eraser.

3. Replace other SIM cards.

4. If the signal is still bad, try to update the mobile phone system version.

5. If the above problems still occur after the update, please back up the mobile phone data (phone book, SMS information, multimedia materials, etc.). ) and try to restore the factory settings.

If the problem still exists after the above operation, it is recommended that you bring the purchase invoice, three-guarantee certificate and mobile phone to the local Samsung service center for inspection by engineers.
