Why aren't my texts going through?

[windowsuser2016]

They don't show up as "can't send" but the other person never gets them. This has been happening for a while and I'm missing a lot

Is it just the one person that's not getting them? Or is it multiple people? Which carriers do they have?

Have you restarted your phone lately? Shut it down completely and wait a couple minutes, then reboot normally. This can sort out a variety of issues, especially network connections.
