Hi guys

I'm looking to upgrade my precision m6400 with a Dell / Ericsson 5540 mobile broadband card.

Specifically this one!

I'm pretty sure I can install that card (the aerial cables are all there) put a Telecom XT SIM in and be away laughing.

It supports 850 /2100 WCDMA, is there anything else that might trip me up?

Thanks, hopefully this is a easy one to answer
