I found the perfect plan with OpenWeb.

I am very happy with my new mobile sim card product. I use no more than 100gb when commuting from home to work and back each month, so the low priced mtn option really appeals to me. I recommend for anyone who travels because this works great in a phone. I use a mobile router however because I keep my telkom sim in my phone. Works just as good! I will be sharing the results with my family as well because this is very convenient. The best part? NO CONTRACT like with other ISPS. praise be!
