Error 1035 from apple voice mail.

I recently switched carriers. I never needed to adjust any settings with the previous one. I clicked to listen to a message and got the message that voice mail was not set up error 1035. I tried following previous solutions but the options were no longer good. One said to check if I had cellular data turned on. (I do.)

This is on the 14+. I am running 18.3.1.

Thanks.
