MTN Nigeria just updated its share & Sell USSD Code used for changing PIN in case you one of those that uses this service, the popularly called mtn transfer now has a new code for changing its pin similar to the code used for initiating a transfer.
You would recall that to activate the mtn transfer Pin was *601*DEFAULT PIN*NEW PIN*NEW PIN# while to transfer credit was *600*RECIPIENT NUMBER*AMOUNT*PIN#.
Now both to change / activate your pin and to transfer now as the same code "600" to change your pin use *600*DEFAULT PIN*NEW PIN*NEW PIN# While to transfer remains the same
Buh hey you can decide to transfer some credit over to us here lol.
