This picture was taken by me today 01:44pm at an mtn office in ado along fajuyi park beside an eatry. I equally visited d other office in front of enterprise bank in fajuyi park, i ask the security about the sim registration but he told me that the people on ground are over 350 then i walked to the other office beside the court (the new office) but the number of people on ground are 200plus. So if you have tried to check your account balance and you recieved a message like this "sorry, you cant call, browse, recharge until you register your sim as required by the ncc. Visit an mtn walk_in centre to register your sim. Thank you !. So be wise now to go for yours oooooooooooo

Will I be able to receive calls and messages?

No. Except from ncc
