How to fix 'Your SIM cannot be registered' problem with Moto G2 on Marsh Mallow I have moto g 2nd generation mobile with android marshmallow 6.0.

The problem is suddenly one day, one of my SIM doesn't get signal at all and I tried these steps:

settings&gt;More&gt;Cellular Networks&gt;Connect automatically then a prompt saying your SIM cannot be registered or Cannot connect to this network right now. Please try again later.

Then I tried to select manually the network that my SIM belongs to. This time the prompt is No Service Selected network unavailable

I did removing SIM and inserting in other slot, rebooted, turned on air plane mode and off etc.. nothing worked

If I insert this SIM in other Mobile it works.. and other SIMs work fine in my mobile.

I also tried dialing *#*#4636#*#* and did Turn off radio and also selected GSM only GSM auto(PRL) wcdma only etc but nothing helped.

Finally I tried factory reset, even this doesn't work.

Device detials:

Moto g2 XT1068

OS: Android Marshmallow 6.0

SIM that has problem: BSNL.


This issue is not there in the beginning and I remember I didnot install anything new or change a setting.

I couldn't get a solution even on the community or on google. Please do help me.
I did some searching and it appears this is not restricted to yourself.  I mean if it works in another device (with full BSNL functionality) then you have limited the problem to this specific device.  I found the following page from a Moto G User which may still apply for you if you would like to give it a shot:

I am also wondering did you try to remove the SIM from the slot it is not working in plug it in to the slot it is not normally in and REBOOT the phone and see if you have it fully working.  If this is the case then it is probably an issue with Marshmallow recognizing the second slot which from looks of google search seems to be an issue they encountered when Lollipop upgrades first hit too.
