The Electric Network people in Ireland wrote again asking if I'd take a "smart meter" and there was a number to ring.
Apparently the modem even on brand new ones doesn't do 4G, and the 3G is gone in many places, so it uses 2G-GSM-EDGE.
Also the same one works for any retailer of Electricity.
So does the Kindle DXG still work? Amazingly Amazon must be still paying for a SIM contract. It works.
On the Web Site you go to the library/content page and send a book, then select the DXG.
On the DXG you enable "Wireless" and then "Sync and Check for Content". Indeed pressing Menu to see connect mode always shows EDGE now (the high speed 245 k 2G GSM, regular GSM is 14.4 k). Then it downloads.
In calibre, unlike KFX which give a mono cover, the cover on the Mobi is colour. The particular mobi had cunning attempts to be like the epub / azw3. Amazon seems to replace the original SMALL CAPS chapter lead in <span> with a <samo> tag. I have also both azw3 (D&T) and KFX (whispernet) versions for a newer kindle.
How curious.
For many ordinary novels the epub from the mobi won't be much worse than KFX, and the spans & CSS can be edited as easily on the epub conversion. I must try an ebook with illustrations. The DXG still goes due to having the battery replaced.
They might cut it off either by cancelling the SIM contract or disabling basic mobi. We can only speculate. OTOH newer models might get a newer unreadable KFX.
