AT&T Messages via WIFI Problems!

[AC Question]

I have a BLU Pure XL, but it didn't work on my Note 4 as well, so I am using the ATT messenger app, and I work offshore. We don't have cell service here but we have WIFI. I can receive text messages , but I am not able to answer! Not even mention about wifi calling is not available. So I am not buying an Iphone to do this, and will not buy a Note 7 either, I feel it is marketing ( pushing people to buy more expensive phones) , and not a phone/app related problem. Anyone can help me with this issue? I don't want to use any 3th party app! I want to use my original number without any extra charges to able send back text messages.

Just an observation, Are you able to receive a 3G or 4G signal?.. If so then disable the wifi and try to send or answer a text using the 3G or 4G netowrking.
