Samsung chat messages

[Emmachaplin87]

I recently ported my number from Vodafone to O2 and now when texting it does not auto change to a chat message. I believe when porting this is a common issue. I think the 1st time I had this a new SIM was sent but in more recent years some phone settings were changed.

It's in settings under chat settings >Rich communication settings

There's only a slide option on that to turn on or off
