Update: Sorted just in time.Price Plan: Business Access Mobile (Known internally as Number for Life)
Price Per Month: R6.15incl vat

All 7 prepaid lines have been migrated to our business account on that number for life plan as detailed above and in the nick of time too, because all 7 sims were delinked from our 2 main datashare sims yesterday. I was able to add them again this morning via the new MTN App so all sorted and at least I won't have to load R2 airtime and send a sms every 80 days on each sim to keep them alive now.
One annoyance of the process was having to remove each sim card and write down the sim card number onto the application form, but I got it done.
