Ever since the August 2017 Android Security Update for the HTC U11, I haven't been able to send texts. I can still receive texts and send/receive calls, but I just can't send out texts. I've tried every messaging app, but the only one that happens to work is Verizon Messages, and that's only when I have a WiFi connection.
What is the story w/htc and Verizon? HTC makes a great phone but it is nearly a brick on Verizon. I'd love one but no thanks to the both of them for their inattentiveness to these issues. So sad to hear of the issues and money wasted.
1), Try wiping the system cache (not the App cache, although for the normal messaging app, you could try that first):
2). If that didn't work - back up the important content you have on the device and perform a Factory Data Reset.
I had the same issue with mine; two days ago I suddenly lost the ability to send a text. So what do I do? I rebooted, like I would have suggested to anyone. Unfortunately, upon start up and ever since, I have no cellular connectivity. None. I now have a wifi-enabled paperweight. I love this phone, and I really do love HTC, but Verizon absolutely crippled this device on their network. I'm in the middle of trying to return the device to HTC, and I'll likely go with a Google Pixel 2 from Verizon (business account with them and I don't have a choice of carrier). Such a shame.
I've had this issue as well.. Today I lost my SMS ability for the third time. I've factory reset twice already and will have to do it AGAIN. It's beyond frustrating. I've called Verizon who says the network is fine and it's the phone.. HTC says its the sim card and account settings.. I'm about to pull my hair out with the frustration this causes.. I don't have time to continuously factory reset, nor do I want to. I am NOT a technologically skilled person to be able to do the things some of the posters have done in an attempt to fix the issue. I just want the phone I pay so much for, to work properly with out me having to reset the thing.

I rely on my messages to keep me connected and definitely want to make sure you can rely on your text messages, MELWIL97. We'd like to look into this together and figure out what's going on. Just to confirm, what is the make and model of your device? Have you tested a new sim card? What happens when trying to send and receive text?

This is still a problem. I've spoken to Verizon on the phone, and HTC, and each of them blame the other.
This is really unacceptable. Why did it used to work and doesn't now? Does anyone care?
