Multiple pay as you go provider with one phone ?

Hi,

Does anybody know if I can use my Samsung X475 phone with mutiple
pay as you go providers. I am using T-Mobile and I would like to
add cingular pay as you go also. The phone supports both providers
it appears since it will let me attempt to connect to either network.
The question is can it be done ? Do I have to switch sims to do it ?
I want to be able to use cingular when I go to the islands where
t-mobile has not coverage...

thx

You need the phone to be unlocked, and then you simply need to swap SIM
cards.
