I just acquired an unlocked Blackberry RIM which I plan to use while in Mexico.

I was in BestBuy and I was told that they have a SIM card that allows calls to be made and received in the US.

My delimma:

I am only planning on using the phone while in the Playa area calling the US.
I also could only use the phone when called. I am looking for the most economical way to stay in touch.

Thanks

PS My first post so be kind.

Scott
