Device locked or unlocked? - Donnieclark - 10-11-2017
I've recently purchased a second-hand Samsung Galaxy Tab S2 9.7 'unlocked' from O2, and am having problems getting a (non-O2) SIM card to work in it.
1.. I'm getting message 'SIM network blocked. Enter network PUK'. I put in the number supplied and I get 'Network unlock unsuccessful'
3. , When I go into Settings, Search Networks, it will only show O2-UK
4. On my start screen I also get message 'Invalid SIM card, network locked'
4. The above suggests the device is still locked to O2.
I didn't find the right solution from the Internet.
