Just started running into these errors about a month ago, I figured it was just network hiccups by Verizon, but now I'm not really sure if it's that or a combination of that and my HTC Droid Incredible phone?
The actual error code is:
Cause Code: 1
Error Class: 3
Thing's I've done thus far:
1.) dialed *228 and did option 1 and option 2 in two seperate instances, after having removed the battery from the phone.
2.) Cleared the cache for dialer and messages on my phone.
I'm not sure what else I can do.
I can Recieve messages FINE.
Just when I send, no matter what network (friends on AT&T or family on Verizon), I get the SMS error code, and cannot send texts.
This is really frustrating.
After a little bit of testing, I think I might have discovered something.
If you send to the phone # with a +1 in front, it will give you SMS errors. If you send to the person without the +1, it works FINE.
