When I was in Europe visiting, I found that my carrier: T Mobile did not charge me for data or text at all. I use an iP6s at that time and found it very useable with my US number...
The iPhone 5s and the 5c use a nano SIM, while older models use the somewhat larger micro SIM. Be sure to buy the right one and try it out in the store before you pay for it. Unlocked phones are those which originally belonged to a specific carrier but have been manually unlocked by someone with the requisite expertise. Although in most cases these phones should work on almost any network, they are less reliable than true SIM-free phones that are designed to be used in several different countries on multiple networks. You need iOS 6 or later to use FaceTime over Cellular. You might notice decreased performance on some carriers while using FaceTime over Cellular on 2G networks. May include an additional fee or requirement. Some iPhone devices are unlocked by default. Contact the carrier for more information.

Can I use a gsm unlocked phone for carriers in south africa.
I was on the GSM towers with T Mobile and since they are partners with other country's GSM - no charge - was a nice surprise when I got home with no extra charges....
It's a shame that the new iP 7 does not do both GSM and CDMA like the 6 and 6s did.

BTW: Other carriers - they charge a lot for use of your US number in Europe - my GF was charged $40 for international data use on her ATT phone! So just do what others have done - go get yourself a data SIM card when you land in any European country and use texting and data for pennies.... Of course it will not be a US number...
