You can't send text messages without an active SIM card. You definitely can't use the Verizon Messages+ application on an inactive phone.

I use other party SIM. phone call and website view running OK except text message. I also download other message program but no luck. when I sent text the Verizon warming also pop up

Did you add the APN for the other carrier?

yes. try AT&T and T-Mobil SIM card already.

Did clean data and reboot software. The problem still there.

Thanks for help. I will use this device as backup phone only.
