There is a thing for unlocking the bootloader, but I don't think that's the same as unlocking the SIM network, whcih I can't find.
I also tried the paying service suggested by giffgaff but they failed to unlock my phone, and reimbursed me saying that my IMEI number wasn't on their database...
So I'm finally tryingt o do it via my network providor, which is Giffgaff, but they don't offer that as an option in https://giffgaff.com/unlock/services. I presume that's because my phone will have been locked to another network before I started using Giffgaff. This adds to teh confustion, as surely I would have had to unlocked my phone for Giffgaff to work. Anyway, I can't find out what that network might be
I hope I'm not the only one to have struggled with this. Any help much appreciated
Hi I recommend you to go to eBay and search for your phone and type in unlock code. You should find one that is cheap it shouldn't go over £10 Make sure when purchasing that the sellers feedback is very good otherwise you might not get the code Hope this helps you
