Hey guys, I purchased a HTC One (M7) stating it was locked to Telus (Canada) and it can be unlocked. Went through two unlocking sites stating the carrier is Telus along with my IMEI and both sites returned stating that my phone could'nt be unlocked. After a while I noticed the model number on the back which is PN07120 and it came back as a AT&T model on Google search. Will I be able to unlock it choosing the right carrier this time or is it going to fail again since the IMEI number is whats important? Any advice?
