Since Smart phones, we have always rented a SIM from Sharon.
I will probably buy from UTS when we arrive. Do you just call them to top off if you run out of time?
We really don't use the phone much--mostly for reservations and a quick check home.
Or if my credit card company decides to send me an urgent message!!!! I almost forgot--- changing airline reservations <img src="http://www.traveltalkonline.com/forums/images/graemlins/jester.gif" alt="" />
