TTaking over 30 min to receive text messages and send them, tried a factory reset no help
I'm having a similar problem. I'm not recieving texts when they are sent, it sometimes takes hours to get some. It's intermittent, texts work fine most of the time.
It happens at various times of the day in different areas. Sometimes it is a group text other times just one person.
I have a galaxy note 3 and have used the stock sms program and Verizon messenger app as well. I was running old kit Kat android and have tried upgrading to lollipop to no avail. I did a factory reset as well. It has been an issue for 3 months. Happens mainly in group texts but now single person ones as well.
