Thanks for all the S.A. phone/tablet suggestions.

So I'm bringing an ipad with me, which I put skype on. I'll try it when I have internet access, but I'm afraid that won't be too often. We're spending more than a week in Kruger, and I understand internet access is limited there.

So that leaves the phone. My son has a non-data T-mobile prepaid phone (he does have a text plan on it). Before I leave the USA, just pop the SIM card out of it "just to be safe," right? And then when I land in S. Africa. Buy a SIM card. Are the prices for these "fixed"? Where do I buy one and what do I ask for? Is there one company that has better service/lower int'l rates than others? (Like what about in Kruger?). I assume I automatically get a S. African phone number with the SIM kit. Anything else a non-techie should know?

BTW, when I have to make int'l calls from the USA, I typically use Startec, which is usually just a few pennies a minute. But I see a call to a S. African land line is about 8 cents, and to a S. African cell phone is almost a quarter a minute. That's almost real money! Any way for USA folks to make these calls for less? And about how much per minute should I expect a S. African cell phone call to the USA to cost? Thanks!
