A customer of mine has a 3G data card but has an ultra-portable laptop that does not have a PCMCIA slot to plug it into. I am going to advise them to put the sim card into a 3G phone instead and use it as a 3G modem over Bluetooth. The phone is a SE V630i. What is the viability of this solution - would it work as fast as a data card? If not, what other solutions could anyone suggest?
