Hey, so I bought a Blackberry storm off the Ebay. When I got it I sliped one of my vodaphone sims in, which the phone is locked too. I later discoverd that the BIS is not avilable on Pay as you go; only contract...

If I unlock the phone, and put another network's sim into it, would it be possible to use the BIS? If not, is ther eany way possible!?:(

Thanks for any help you can give me in advance!

Orange have PAYG with BIS, and they are the ONLY network with PAYG BIS.

You can get SIM only plans (a 30 day rolling contract) from O2 or T-mobile that also offer BIS

OR get a full contract from any provider (bar Virgin, Tesco Mobile) with BIS.

Cool, thanks for the info.

And how may I sign up for BIS on any of these providers?

Thanks

Go into the store, do it online.
