I recently bought a card phone 2.0 from eBay and am having a few problems. I cannot find a fault with the actual card and believe it to be working fine. However when I put in my SIM card (a Pay as you go 02 sim), the card phone can never seem to make a connection. When I launch the Mac software, the signal strength is zero (and when I try to use it as a modem it states there is no carrier signal), and it cannot read any contact info off the sim card. I've double and triple checked the card is in the right way round and I should have enough signal strength, since when the sim is in my Nokia 7110 the signal strength is nearly maximum. Can anyone suggest what might be wrong?
