    Dear Senior Members and developers/experts,

    I need your urgent help regarding the issue of mobile data that I am facing in recent days. Please see the pic as attached. My device info is also attached for your information. I am using Galaxy S6 DuOS and facing the mobile data problem. When I select GSM Only (2G) (Attachment 2), my mobile data is all right. Sim 2 selected GSM all time (Attachment 3) with no problem. I am using mobile data from Sim 1. When I select WCDMA/GSM (3G/2G), my mobile data HSUPA showing connected but no internet connection and emergency calls only appears (Attachment 4). And lastly UMTS and mobile network state disconnected (Attachment 5). Please note that my IMEI 2 is not valid according to IMIE.info and mobile info application. I have the mobile data available when I purchased but after OTA update, this problem occurs. THen I flash sam firmware but no improvement. Any solution regarding this will be appreciable. Thanks.
