Your proposed solution are based on dedicated simcard. As there is not need for permanent online for DB it would be nice to have possibility to use my mobile phone.
I can do it right now using following setup: Nokia via Blutooth to Notebook, notebook via Ethernet cable to DB. There is drawback in this scenario - I have to connect and switch on my laptop every time I want my DB to be online.
I'm keen to know if there exist some configuration where can archieves this without computer
