Hey KC, I also utilize AT&T/Cingular for my cell service. I set up to have the service added (I believe it is about $5.00 per month additional) that allows me to connect to the local cell provider BTL while in San Pedro and I can receive calls as I normally would and make calls to local numbers without dialing long distance. I think the only stipulation was that your account be active for over 3 months or something. Worth a phone call. Hope this helps!

I've done it both ways - set up the $5 additional charge, and just used as is - not much difference in price that I could see - but I was never on the phone for more than about 2 minutes. My account doesn't have roaming charges, so that could make a difference. Dita is correct - I'd say call AT&T and get some info from them re: charges.

Also, if your phone is turned off no charge for voice mails left, but if it is turned on, there is a charge. I could never get a good explanation for this from AT&T. There is a charge to check your voice mail, and you have to call a US number to do it.

I do not have AT&T (T-mobile) but had no problem using my phone. I would HIGHLY recommend you call to check what the roaming rates are if that applies to your account. I needed to use my phone and the bill ended up being $818.00 @ @2.99/min for roaming charges. My texting was cheap considering at $0.35.

If you have T-Mobile or Cingular just buy a prepaid card SIM at the SP phone company office for about US$10 for local service. You must get your phone unblocked while you're in the US.

If you need it for contact with USA just increase the prepaid amount. It will be cheaper than roaming on your US account.
