Hello guys,

Today i'm going to showing you how to fix the 3G disconnection for M3s. I has tested this metod with my italian friends and is working. We have tried also for M3 Note, but for that model this has problem. Anyway you can try.

1) Open telephone app and digit *#*#3646633#*#*

2) Now go on Band Mode and select your SIM Card (In most case is SIM1)


   

3) On UMTS section disable the band that is not using on your country. You can check here https://www.frequencycheck.com/carriers
Please pay attention to this step and selected the right band!

In Italy is the UMTS global band, so i checked only
WCDMA-IMT-2000 and WCDMA-GSM-900

Click on SET.

 

4) Go back and returned in Main Menu, click on Antenna Test and in section Antenna Test (3G FDD) selected
Resume default setting

 

5) Go back again in Main Menu and click on AMR-WB on/off and uncheck Enable UMTS AMR-WB

 

6) Go back and set your M3s only in 3G. Now everything is working correctly. I tested for one day and hasn't lost the connection.

Probably this guide become useful when Flyme Team fixed with a new release, but for now you can use this workaround and i hope can help also you.

This guide cannot guarantee the 100% that 3G will work correctly for you and you are only the responsible for the change. So pay attention and don't try to change settings if you don't know what you are doing.
