My phones Sim card isn't working properly.

So recently my phone, (about 1 year old) has been having some sim card problems,

Data works fine, no problems.

I can send texts, but only with a picture. when I try to send a text without a picture it says “CB Null” and a red explanation mark by the text to show it hasn’t been sent

When I try to make a call, it says “No Sim card or Sim card error”

This all started after I went on a trip overseas to hawaii, and when I got back these problems started, the phone was off most of the time and I didn’t damage it in any way. I checked the sim card, its still in there.

My service provider is ting.
