All I can tell you is be very careful. My daughter set up for 4 day trip to Canada to use her blackberry and tmobile charged her $500 for internet access that she did not use or initiate. the company appears to be really ripping people off. another daughter took her iphone to europe but disabled the phone and just downloaded an app that allowed her to use skype from her phone for free whenever she had wifi available..also skype will work from her computer if she is hooked up to the internet. For $3 per month you can get a fixed number that has voice mail etc. Or a magic jack that plugs into the computer works if you are online. Skype requires less equip though. That was very successful. good luck!
