Is there a way of having one mobile phone number on 2 separate sim cards and if so how or where can i get one?

I have a sim card in my PDA that has an unlimited data plan with T-mobile that allows me to surf the web using 3G. I am thinking of buying one of those Ultra mobile PC's which can also take advantage of mobile 3G but don't want to have to get an additional contract or keep swapping my sim card.

Couldn't you connect the PC to your mobile and use it as a modem? therefore not needing a new sim or contract.
Reply:The ESN (Electronic Serial Number.) is more important then the mobile number. The system uses the ESN to track the location of phones so that it can direct calls to that phone.





What you want to do in effect is have one phone number on two different ESN's. The system would be trying to direct a call to two different ESN, and would not result in the best possible service, particularly if the phones were located in different cells at the same time.





You would get a lot of drop outs, calls going astray and not being received at all. In short, the answer is NO, not legally, and if you could do it illegally your service would be cr.p
