Watch4 LTE - no texts

Just wanted to add my 2 cents.  I know the watch does have its own data plan because I can make and receive calls on it with the phone off.  I can also say that the techs at the stores I have been to have tried their best to figure it out but they don't really have much knowledge with Samsung products, or at least as much as they do with Apple watches.  The issue seems to be limited to texting which is the main method of communicating these days.  It is very frustrating.  Does this issue occur on Verizon or AT&T as well?  If I can get this to work, I would love my watch, now I only like and and should probably stop paying for the data plan.
