View Full Version : Check Sim on Mars Trium

05-12-2002, 11:17 AM
I have two Trium Mars phones.

One appears to be Vodafone and the other O2. When I switch on both phones they show CHECK SIM.

I have purchased a data cable in an attempt to unlock in case that was the problem, but this does not change the message.

Is Check Sim the Trium way of saying contact service.

Either way I could do with some advice.
