I'm going to Spain and want to use my Tour over there, it's native to the Sprint network in the US. Can I just purchase a prepaid SIM card in Madrid and pop it into my phone or do I have to use the Sprint supplied SIM card? Sprint charges $1.99 a minute in Spain and I believe I can purchase a prepaid SIM for less cost per minute when I get there but does it work?

From past experience with the Sprint 8830, the SIM card slot should accept any provider's card, but you will not receive your e-mail with a PAYG card. You will only be able to use voice and SMS service.

that works for me, thanks.
