I've got a factory unlocked iPhone 4 currently running iOS 5.0.1 that I bought online from Apple in February of last year. Used it on Vodafone, Meteor and Three without issue. I switched to 48 last weekend however, and the phone is not activating. Both iTunes and the phone display this message:
"The SIM card inserted in this iPhone does not appear to be supported.
Only compatible SIM cards from a supported Carrier may be used to activate iPhone. Please insert the SIM card that came with your iPhone or visit a supported Carrier's store to receive a replacement SIM card."
The strange thing is, I tried the sim in unlocked Nokia and Blackberry phones and it works. When I tried the sim in another unlocked iPhone 4 running iOS 5.0.1 I got the same message.
I've tried everything- restoring and updating from DFU mode, jail breaking and installing SAMprefs, even activating using other sims from O2 and Vodafone and then trying to hacktivate the phone using the 48 sim through jailbreak by installing a custom profile containing 48's APN settings- pretty much anything that Google has come up with I've done, and nothing has worked.
I emailed 48 support on saturday, twice they just suggested googling for a solution as there are a lot of similar iPhone cases around the world, and they linked me to suggested solutions they thought might work- no joy, but at least they were fast replying and tried to help.
I called Apple later that day, they said it could be to do with the software on the phone or that the network is so new- however an unlocked iPhone 3GS' I have seen on the 48 network does not have this problem. I've yet to hear anything back from apple regarding the matter.
Is there anybody else out there with the same kind of problem? Is it possible 48 have to submit iPhone carrier setting to Apple to have make their sim cards supported or something? Feel like I'm hitting my head against a brick wall at the moment, so any help would be appreciated!
