Q: iphone unlocked but won't accept new SIM

Yes I've already done all this - Telstra says online that is unlocked, I've restored and nothing is different. Any other ideas?

I've restored the phone but still won't work. I'm now in touch with Telstra who told me the same but I don't understand why I need to wait 72hrs if the phone is never locked in the first place? The crowd support on Telstra us is telling me iphobe5 in Australia might not be 'same frequency' as uk sims????

OK all solved. Despite Telstra saying they issue all iphone 5 phones unlocked, you still need to contact them to get it unlocked... go figure. Once they have done this, which is immediate, despite the website saying it takes 72 hours, all you do is sync and you are in.

Thanks for everyones help
