Just see the difference after disabling the 2nd sim

edited March 2021 in ROG Phone 2

This is the issue i'm facing since very long. Most of the time even after disabling the second sim won't make any difference i have to put my phone on flight mode several time, and when i'm using hotspot i need to make sure my phone's screen is on otherwise i am unable to access the internet.

Sometimes when i'm using YouTube the internet gets disconnected and for that i have to put my phone on flight mode then it starts working and yeah, both upload and download falshes in the status bar.


  • HI,

    Try a different SIM or try swapping SIM.

    Run SMMI test to check if this is related to hardware

    How to Enter SMMI_TEST (test hardware)

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

    you will be entered to SMMI_TEST

    Update your phone's software to latest version if not.

    Last step would be:

    Kindly visit the nearest service center:


  • Sim is working fine on another phone, but swapping the sim is nightmare, I can't even send a whatsapp message.

    I am using the latest version of software and SMMI_TEST passed even after swapping both sims.
