Hey @JeppePeppe , hoping you might know the answer to this one? Screenshot of the error attached. the registered number is the correct number for the service ported into Tre from another carrier. Could there be a conflict between the original simcard number vs the activated/ported number causing this issue?

Hey, my partner had the same issue a while back. I just “restarted” iMessage. 
And then it just started working again. But, sometimes you have to remove it from imessage and start the process over. 

 

Ah good one Chips, removing the number and adding it again was a fix ! Cheers and thanks 

Hi @Sasha Jovanovic! 

Sorry, I wasn't available last week, as to why I didn’t respond.
Glad to read that @Chipsgeneralen’s tip fixed your problem!
