SIM failure - unable to unlock iPhone 4 after using iphone 6

[Anonymous]

I'm currently having to use my old iPhone 4 while the iPhone 6 is being replaced. I've inserted a new SIM card whcih is not recognised. The device states a SIM failure with no service. I've downloaded the O2 app and when i navigate to the unlock device section the information shows that the phone is my iPhone 6. It seems the iPhone 4 is not being recognised and therefore is not being unlokced properly to allow the new SIM (STC Saudi Arabia) to work properly. I'd appreciate to be able to contact a support person directly with the IMEI numbr of the phone I need unlocking in order to get this SIM card working.

Thanks for he help. I've submitted via the online form. Hopefully that will work.

You need to use the o2 network to register the phone before the unlock can be requested and it won't work from abroad either I'm afraid.
