I have a new Samsung A21 which I purchased in the spring, and just got hooked up around Memorial Day weekend (end of May). Sometimes, maybe once a week, the phone won’t send texts. It will receive texts, but not send. I will get a failure message. I will try repeatedly and I keep getting the failure message. It may or may not cut phone calls off, too.

This has happened three separate times in the past three weeks. All three times, the next day the phone works fine. Facebook, Google, Waze, Shazam all worked fine while I had the texting problem.

In my quest to figure out what the problem is, I have deleted Facebook and deleted Messenger, thinking maybe it would help.

I had the problem last night, then this morning it was sending texts fine, and now I have it again. I’m on the verge of returning the phone but don’t want to do that if there is a simple fix.

The phone is not in Airplane mode and the texting issue will occur without anything being pressed. Another detail is it happens when I’m out as well as when I’m home (so I don’t believe it’s a WiFi issue).

Please help!
