'Restricted Network' Iphone 4 - Orange
I have just bought a new orange sim card, and inserted into an iphone that I bought off ebay.
It is iOS 5.0.1 baseband 04.08.11.
It does not connect to the network, and when I go to the settings and turn automatic network selection to 'OFF' it shows me the various networks. When I click on the Orange network it says the network is restricted.
So I thought I may have been sold a blocked IMEI number phone, and I did an online check with checkmend.com It says that the IMEI number is not currently blocked.
Why won't it find the network? Any suggestions would help.
