I have been getting message not sent errors 4/5 times when I try to send an SMS text message. It's getting really annoying. A restart seems to fix it for a couple minutes but then it begins again.

Any ideas as to why this is happening?

I am having the same issue. ATT 6s Plus SMS text messaging saying not delivered message not sent. My wife has a 6s ATT and SMS text messages go through fast and get no errors. I did some troubleshooting with ATT tech support , and even got a new sim card from the ATT store. Issue still exist at least for me. Anyone else?

It's been happening to me intermittently since I made this post. Not nearly as bad as it was when I created this thread, but it's happening a couple times a day. Not sure what the cause is.

Yes, zero problems with iMessage. Only SMS.
Had the same problem... with AT&T

Try this...

Settings - Cellular - Enable LTE - Data Only (I had switched mine to Voice & Data). This worked for me.

Some others suggestions for similar problems have been. Reset network settings on iPhone, remove text forwarding to all devices and then reboot, restore iPhone. I haven't tried any of these. (First step worked for me).
