[Q] HTC Sensation won't let me enter my network unlock code
I have the network unlock pin for my Sensation but when I put in a different sim from another network the phone just says no sim card inserted and asks for a PIN number.
The phone is locked on 3. I tried with O2, Giffgaff and Vodafone simcards and I get the same thing. The simcards work fine with my older phone and neither of them is locked with a pin number. I tried the default PIN for the respective network and I got a message saying Incorrect Pin. When I enter the unlock code (even though not prompted for that) I get the same message.
Has anyone else had that? Any advice?
Thanks in advance
