Samsung S7 network problems
with this message I'd like to report a problem concerning my Samsung Galaxy S7. I've recently bought an ATT model on the web, but I've noticed that it was previously "debranded". When I insert the SIM, it is recognized without problems, but it's not allowed to connect to any network operator. In detail, if I go through "Connections"> "Mobile Networks"> "Network Operators", whenever I press "Search Networks" I get the message "Error while searching networks" or "Can not connect ...". I checked the IMEI and it's ok. So my question is this: is there some kind of blocking by ATT? In case, could it be possible to unlock?
