Pls..... help me by giving the codes to fetch TEST MODE & SERVICE MODE in my zenfone 6. I have an issue in NETWORK BAND changing. it does not change automatically, locked at one 4G band. So I get very slow internet speed at that network band. Also I want to test my camera & sensors works properly or not.


  • Hi there. kindly follow the below steps:

    1 . To enter SMMI test

    Go to Calculator=>type " .12345+= "

    you will be entered to SMMI_TEST_V4.1.35

    Select Receiver1_Test=>Press Start to check 

    2 . You can't change band by yourself so if you have any internet connectivity issue you can switch SIM and see if the issue remains

    3 . Update firmware version if you have not already.

    4 . Check with your network provider if the issue persists there.

    5 . Last option would be to visit the service center to have a

    check. Locate here: https://www.asus.com/in/support/Service-Center/India
