Certain Text Messages Failing to Send

[gary4540]

I have a Samsung Galaxy S9. No issues with receiving or sending text messages, except:

- Automated messages I receive from, for example, my bank and medical providers confirming appointments or seeking authorization.

- In either case, my response is to be 1,2,3,... or Accept, Confirm, Yes, No....

-Once I type my response (1, Yes, etc), I see an exclamation point to the left of my response. -

-Pressing on the exclamation point brings up a "Couldn't Send Message" notice with the option to Resend, Delete or Edit.

My wife has the identical phone and doesn't have this problem. That is, Yes, 1, Confirm, etc., sends successfully. I have to assume that this is a settings issue on my phone, but can't determine which setting.

Hey there and welcome to the Samsung UK and EU Community Customer to Customer Forum

Sorry to hear of your issues.

Just a thought, where you are replying to messages, are they chargeable messages (i.e. to a short SMS number) and if so do you have a spend cap set on your account with your network?
