Samsung Galaxy S7 Edge I have hit a dead end with trying to move to an alternative network provider. Currently with O2 and I want to move to BT. I didnt think my phone was locked to a network but have tried the BT SIM but get message SIM Network PIN Blocked - Enter SIM Network PUK. First of all I asked BT for a code. That didnt work so I suspect my phone is now locked. Have asked O2 4 times for help. They take several days to respond. All I have now is an Unlatch code which doesnt work. Asked Samsung for help and they referred me to O2, my current provider. Have asked for further help but getting nowhere and this has now gone on for 4 weeks. Any suggestions would be very welcome??
