I have recently bought a 2002 Volvo S60 T5 which has the factory installed in -car phone system. I would like to use it but have been advised that the GSM SIM which works is outdated and it is unlikely that I will be able to purchase one. It is a small size it seems and the latest version is 3g

Any suggestions as to what I should do or where I may buy one
