No carrier name in status bar but a meaningless number!

[H1984m]

My iPhone 6s shows a meaningless number instead of sim carrier name in the status bar, how it’s possible?
Nothing solved it, like resetting, restarting, updating iOS and so. Plead help me, it’s so ridiculous!

It's a Network Code. That one is MTN Irancell, Iran's second largest mobile network.

This is a non-problem and does not require a solution. Not sure what’s so ridiculous about it as it doesn’t affect your performance or detriment to your handset experience.
