I did a bit research and purchased today the IMHO beautiful Doro Primo 413
dumb phone (for elderly people) and it includes a USB C to USB charger/data
cable, which then can be connected to an offline Notebook.

Once my batteries are charged, later today, I will try out the following:

Preparing a PGP message, converting it to JAB-Code and then transfer the
.png image( less than 300 KB, due to German Telefon Carrier specs.) to the
dumb phone. 

Finally I will prepare an MMS and load the image and send the message for a
test to my smartphone, for later retrival, to see if everything went well.
