Before now, we can keep track of the Value Added Services we are subscribed to by dialing *447#. With that code, we can as well unsubscribe or stop attached VAS.

To stop VAS in MTN Nigeria now, as from 2023 to whenever the codes will be updated again, use *305#.


There is always a need to check balance, this is done daily on average by most Telecommunication users. You need to be aware of your balance status to know if you can make that call, or buy that data plan. *556# is usually the number to dial to check balance, but not anymore. The new USSD code to check balance is now *310#.


Airtime recharge also took part in the changes, *555# is yesterday, *311# is today. This is to say if you want to recharge airtime, don’t type the code this way “*555*airtime code#”, but use this format “*311*airtime code#.”

DATA PLAN: *312#

“Data is life,” that’s a popular saying in this modern day. To access the internet or download games and applications, you need an internet connection, and for this connection you need an active data plan.

Data plan ranges from daily to monthly and yearly, you go for the one that suits your need and financial capability. Previously, *131# is the code to get started, but not anymore. To view data plan, share data, gift data and engage in any data service, dial *312# to get started.


There are just two services under this category, Share Services (MTN Share ‘N’ Sell) and Verification of SIM Registration/NIN-SIM Linkage.

Share Services USSD code has been updated from *777# to *321# and Verification of SIM Registration/NIN-SIM Linkage from *785# to *996#.

One thing you should notice about the USSD code update is the fact that 7 out of the 8 services begins with the number 3. This makes it easy to remember the USSD codes for services as they all begin with “3.” The old USSD codes is scrambled, beginning with different numbers, difficult to remember sometimes.

Hopefully, most Telecommunication service providers in Nigeria will follow suit and work on making their service USSD code as friendly to remember as possible. This is a good change and every MTN Nigeria user will adapt fully soon enough.
