New SIM card

[BlueTree25]

I put new SIM card number.  And touched “save changes “ then “ ! “ mark came up.  
What does it mean? I checked new numbers again. It was a correct number.

HI @BlueTree25 

is the sim card new and was never been used?

were you using the app or the browser?

If enter online then just clear the cache on your browser then enter it again. 
Or you can enter it on the PM app.
