If anyone found an app to correctly monitor 3G data for the s.s.g.t 10.1, please let us know.
In the meantime I also use mtn's website (
https://www.mtn.co.za/MyMTN/MyInternetAccount/Pages/default.aspx) to check my usage on my pc.
Annoyingly, if you visit this site on your tab, you get re-directly to the worlds most annoying site "MTN play". To avoid the redirect, do the following on your tab:
-install firefox (mobile) on your tab
-in firefox, search for add-on's and install "Phony"
-now, in firefox's settings, change the "User Agent" setting to "Internet Explorer"
Firefox Mobile will report itself to the MTN website as a normal I.E browser, letting you access the link above and check your bundle, without the forced redirection to MTN play!
There may be other simpler ways to set the "user agent" of the built-in browser, or other 3rd party browsers, but this was the first and only option I bothered to tried.
