Hello, I've been having this problem for over a month now. Basically when going between WiFI to Mobile Network my phone does not want to transmit data over mobile. When I leave my house in the morning, for example, my phone shows full bars but no network services work, not even phone or messaging. I have factory reset my phone, paid $10 for a new sim card, downloaded network settings multiple times, and all of the above solve the issue temporarily (I believe it's just rebooting the network each time that actually fixes the issue), but this does not fix the issue all the time. Sometimes I need to leave the phone off for a long period, and then restart in order for the network to reconnect. I've searched the forums, and all over the web and haven't found a solution, or another person with my exact problem. Please let me know if this is an ongoing issue with other people - if so how to fix it - or if my phone has a component that is maybe overheating, or not working correctly (related to the GSM radio perhaps) and causing the issue.
Thank you
