    I recently downloaded the Android 6.0 on my Htc One M9 and can no longer make any calls or connect to my mobile data. I am currently roaming in Mexico and I don't know if that has anything to do with it. I have tried connecting to networks, changing to CDMA/GMS and cannot connect to anything. I have Tmobile and had been able to get LTE down here and everything and now I can't. Any suggestions? Thanks.

    Try a Cache Partition wipe.
    If no go, consider a Factory Reset. Let us know if you need advice about backing up before doing that.
