I just got my first cell phone a few months ago. It's an iPhone. I know people travel all over the world with theirs, but can someone explain how that works?? Obviously I can use it here in Muscat, but if I were to take it on my upcoming trip to Egypt, can I use it there, too, or will I be paying exorbitant long-distance rates since it's "based" in Muscat, or what? I thought it might be handy for communicating with the driver or guide or travel agent. If it costs too much to use there, I'll just leave it home.
Please speak slowly and use simple words. This stuff is all very confusing to me!
