Galaxy s8 not recognising sim

[Judith81]

I got my phone yesterday afternoon and my sim still not working. I can't ring or txt, anyone else had this problem, and know what to do

Hi @Judith81

As a process of elimination can you insert your SIM card in another phone to see if the SIM card is working? 

If.it isn't then you'll need to contact your Mobile Network Customer Services. 

If it works then can you try another SIM card in your phone. 

Did your Network supply the Samsung Galaxy s8 phone to you  ?

I am having a similar problem, I've been using my two sims for basically everything until this evening, my Sim1 card tray no longer recognises any sim card, it's really frustrating. It's a galaxy S8 in case anyone can profer a solution.
