My education on SIM cards is very little, but hopefully will be better VERY soon as I am traveling soon. I use an ATT phone which is unlocked for international use. Given that I am traveling the British Isles on an extended trip, I am still not clear after all the reading which company to go with. I believe I'm too late to order on line so can one buy a sim card say in Dublin? What company would be one to buy from for a good price to call around the isles and back to the US. My thought is to use text messaging to have the receiver of the text phone me. I'm not sure really the right route here and am looking for feedback.
