CONNECTION PROBLEM OR INVALID MMI CODE while using 4G

2019-02-21, 5:55 AM

A few days ago my phone just started to behave a little strange, my 4G cellular data speed became slow, it stopped receiving SMS and some short codes are now showing this error message about MMI and when I switch to 3G I get the message in the image... so I looked up on the internet about this and found many different solutions and I tried all of them, obviously none of them worked so that's why I'm here...

Hi leaopedro,

 

Thanks for posting, can you please try the below mentioned and see if that helps.

 

-Reinsert the sim card

-Reset APN settings (If didn't get any APN settings after reinserting, contact Service provider they will send the APN settings again .)

-Goto Settings>>More>>Mobile Networks>>APN settings>>" reset to default"

-Switch Sims with different networks.

Also, try to contact your Network provider as well and check. 

 

Thanks

Sandip
