Selected network not available
I have a Samsung Galaxy A3 2016 SM-A310F.
As soon as I get inside my house, automatically my Orange provider network to make calls dissappears. I tried to change it to 2G only, 3G only. Searched networks manually but even with that, it got registered in network, and 5 minutes later, lost again.
It was bought in Singapore. I heard that maybe the motherboard is the issue.
Once I go outside in the street, works again.
Is there something that I can do about it? SIM is not the issue. IMEI is not the issue.
Any advice will be welcome.
Thanks in advance to all.
