Youare comparing an MTN 200 package to a procall 220? vastly different mate, herewith is an explanation thereof, obtained from one of our pricing managers:
"Brief differences:
Old Procall 220, Subscription R389 which gave you 220 Anytime minutes and per minute billing
New MTN 200, Subscription is R200 and you get approximately 90 Anytime minutes, 25 inclusive SMS’s and per second billing
However the correct package for this person to compare Procall220 with is MTN Anytime 350, where the Subscription is R350 pm and the inclusive minutes of up to 183 Anytime minutes. The minutes may seem less, but combined with the lower subscription and the benefit of per second billing the customer is in a better position.
Additional benefits are:
a. 50 inclusive SMS’s
b. the customer can use the inclusive value for Voice, International calls, SMS, MMS and data
c. the customer may carry over up to 6 months of unused value.
Additional points:
a. As a rule of thumb, it is best for a customer to look at his/her monthly spend, say it is R600 and then select the package with the subscription value (and name) closest to this e.g. MTN Anytime 500. In other words the focus moved from knowing how many minutes you need per month to how much do you spend per month or want to spend per month
b. Yes Vodacom also have value based price plan, VC still offers the old minute based price plans.
c. Many international operators are changing to value based plans due to the additional benefits customers get from these."
I hope this clears up your confusion
