Resurrecting this thread given the new MTN Pi offerings.
I see as an introductory offer, when you sign up you can get a ZTE G5TS for R499, and get 200Gb for R399, which rolls over for 12 months - (up to 25mbps). Source: https://techcentral.co.za/mtn-lobs-a-grenade-into-sas-mobile-market-with-pi-launch/279573/
Seems okay for a backup solution. Any thoughts?
Fixed wiresless and mobile data topups don't roll over as per their terms. Only the monthly mobile data does.
