Since your plan differ heavily from the thread starter, I'd recommend to
sketch your plan and create a new thread if this mail will be oversight.

I think that would also require status reports, send, delivered, read
(optional).

On cellular network the internet connection could go down for a short or
longer time. What happens to messages send when the recipient was
offline at that point? Without a server... Constantly resending the
message would be required? In which time intervals? Try to resend (the
first message) every 5 minutes, give up after 2 days and inform about
failure?
