How can I Check my message center number on IOS 12?

Greetings,

I used to be able to see my current message center number by Dialing *# 5005*7672# on my phone, that showed me right away my message center number, however, I try now that I have IOS 12.2 and I am unable to do so, as for some reason the phone looks like it does something but its instantaneous and does not provide me with the regular message that waits for me to press the dismiss button, I tried also with #*06# to check my IMEI that one works properly.

If someone could tell me the correct code or how can I look into the message center number from the settings I would Highly appreciate it.

Thank you in advance.
