When you see the SIM not supported, SIM Card not Installed or Invalid SIM message it usually means that the iPhone is Locked! How To Unlock Iphone 5 Tmobile Usa. Carrier Unlock is the solution.
Izotope Ozone 4 Keygen Download. I have an Apple iPhone 6 A1586 from the US which was a replacement device from Apple, but the previous handset would've been locked to TMobile (always GSM and never CDMA I believe). I've inserted a new UK (GSM) SIM into the device and it's telling me the SIM is unsupported. I've checked and this tells me the device is not locked and can be activated by a new user but I'm unable to do that.
I've wiped the phone and attempted to set it up as a new device but as soon as that new SIM goes into the phone it locks up saying 'SIM not supported' but it will still work when I put the old TMobile SIM into it. Am I missing something here?
