Galaxy S8+ texting issue
I have a new Galaxy S8+ and am not receiving or able to send text messages to some contacts. I can get and send to some people but there are some I can not get messages to or get messages from. I have tried a new SIM card and turning things off and on. It doesn't matter what the other persons phone is- iPhone or Android. Also the carrier doesn't seem to matter. I can get phone calls from those I am not able to get texts from. Any ideas?
