ELk M1 and voice cellular dialing

HI all DYIer here.  I am thinking of getting away from my copper telco(Verizon).  I do not currently use a central station.  Currently, any and all alarms from Elk M1 are calls via copper to my cell and I also email myself via M1XEP.  What are my options to offer the alarm calls via a voice message as I am receiving now, but via cellular?  I see a few products out there from Uplink, Napco, Leviton, etc. 
All I want is a cellular to take place of the copper landline for these alarm calls. Thoughts? Thanks

Nothing pro level I know of.
 
Consumer grade or generally a Chinese import item that provides basic cell service. HAI's C3 is going to be dead tech if 2G is gone in your area.

As DEL said, units like this are not professional grade.  But this would probably do what you want.

Well yes on a consumer level I do see a Verizon Home Connect unit that I can add a phone(line) to my existing cellular service. Claims it will operate with a security dial out. Two plugs so one for home phone and one for Elk M1 just as I have wired to Verizon copper right now. Just as a follow up anyone heard of this Verizon unit working? Thanks in advance.
