 Has anyone tried to swap out their 3G sim for a 4G one? I received my 4G sim from The People's Operator and activated it and put it in the car phone but received the message "bad sim or not inserted correctly" so I tried it in one of my phones and it worked fine, asking the phone to manually detect the network it came up with Vodaphone, EE and O2 but not 3 which is the new network provider, so I put it back in the car phone and got the "bad sim" message again so I tried my Giffgaff sim in the car phone which worked fine so I assume the the car phone doesn't support 4G. If anyone has any ideas.

 Given that 4G wasn't really released until around 2011/2012, I'd be amazed if the C6 was compatible with it, as it would have had to be forwards compatible from when it was designed.

 You can only get the phone to work with old 2G signal. GiffGaff works because it works on the old O2 network. You can also use the Vodafone signal as that is a legacy carrier. Three started out on 3G so will never have worked with the C6 radio.
