Wrong number appearing in outgoing calls and messages after porting

[NoelleB_2421857]

Hello. My old number has been ported over successfully but the number that appears to people I message or call is the entirely different. However people can ring or text me on my old number. All confusing. Is there an easy solution?

@NoelleB_2421857 It may help to go into settings on your phone and change it manually.
