I know they weren't exactly a hit when they were announced but I would recommend them for anyone who buys 1GB or more. 2GB or more even comes with nite data now! Just be careful, your initial purchase will see you forfeit any normal bundle you have and you'll immediately start using up your dataextenda instead of finishing up the other bundle instead. IT DOES NOT EXTEND A NORMAL BUNDLE BUT RATHER ANOTHER EXTENDA BUNDLE. The other day I extended my 1GB bundle with the 30MB one costing me only R11 to do so, still had like 400MB left over from the 1GB. I don't think the other networks offer anything similar in especially on prepaid.
