Welcome to the forums. It's possible that you need to enable Premium SMS back. Try this. Go to settings - apps - tap 'more' menu - special access - use Premium SMS services - message service - choose 'ask' or 'always allow'. Tell us how it goes.Galaxy S6 does not send to short numbers after I accidentally hit "don't send" when it asked me. Now I can't respond to automated messages from my pharmacy, please help!
Three dots top right?There is no 'more' menu for me to tap after apps?
