MTN Has Finally Reviewed Its Tariff Plans In Secret, Check It Out!

MTN disabled some tariff plans to promote higher plans without giving prior notice. Recall last year that MTN launched two tariff plans: the MTN Xtra Pro and Xtra Special tariff plans. The MTN Xtra Pro tariff plan was touted and recommended as the cheapest call tariff plan on the network.
What makes Xtra Pro the cheapest tariff plan is the ability of subscribers on the network to make off-net and on-net within the country at a FLAT rate of 11kobo/sec (N6.60KB/min), upon successful access charge deduction of N5 daily.
Unfortunately, it was reported from a source that MTN secretly eliminate and discontinued Trutalk tariff, since 5 April, 2017 and Xtra Pro tariff plan with some other tariff plans from its list of tariff plans. So, these are the available list of tariff plans customers can presently migrate to :
√ MTN Pulse
√ MTN XtraSpecial
√ MTN BetaTalk
√ MTN XtraValue
Customers will no longer be able to migrate to the following plans below, but customers on these plans can migrate out to other available tariff plans but can never migrate back again.
× MTN TruTalk (Old)
× MTN BetaTalk(Old)
× MTN SuperSaver
× MTN SmoothTalk
× MTN iPulse
× MTN Zone
Before XtraPro tariff plan was discontinued on the 5th of April, 2017, the code for migration was *401#, but presently, if you choose to go back or migrate to the Xtra Pro tariff plan, you will get a prompt telling you that you are already an existing MTN tariff plan customer as well as giving you the MTN pulse code for direct migration which is *406#.

What's your say about this MTN review? Do you think is appropriate for MTN to just eliminate and discontinued the cheapest call tariff plan?
