How to upgrade my sim to 4G when there is an error in the name

Hello. I registered my sim sometime 2014 when I was about 15 years. Unknown to me the tech guy filled in his details instead of mine. I only got to know when I downloaded the MyMTNApp. I don't know how I can upgrade my sim

Hmmm. This is a tricky one .
But with mandatory use of NIN , you could give this a try.
Visit MTN service center with your National Identification Number (NIN) and NIN Slip if you have otherwise your NIN is okay.

Tell the Rep that you are the owner of the line, fill the request form and put down your frequently called numbers and Last Recharge. Be prepared to give more information on line like year of purchase.

Because it is an upgrade you are requesting, you will get a one time pass code, give the Rep the code if it is validated, then they should proceed with upgrade request and then correct your registration details .

Hope it helps. Thank you
