Who I have the same questioned this topic

This is a recurrent problem (evidently going back to 2017 or farther)

I am trying to send e-mail text messages in the form of:

nnnnnnnnnn @ vtext.com

nnnnnnnnnn @ vpix.com 

nnnnnnnnn @ vzwpix.com 

All of these have worked in the past, now they all get rejected with an "address not found".  I asked about this at the local Verison store, and never got a call back.

I can send messages through two services -  www.opentextingonline.com and textem.net . Interestingly, Text'em has the message of "We have fixed texting to Verizon Mobile December 5th 2019".

So what is the problem here?  There have been complaints about this for 4 years.

Verizon - please do a definitive fix on what is (at this point) as "ancient" Internet Protocol, and post as FAQ **prominently**!!  (BTW, the dumb "Chat" support dose not recognize "e-mail messaging" or "email messaging".
