Fon Network
===========
 - FON network
    * Original "La Fonera" devices      - few useless
    * Partner FON network               - good coverage, unreliable
    * Premium Hotspots in Shops, etc.

 - Access to global network
    * Seems possible using any method described bellow
    ? But this probably does not include Premium hotspots in other countries
    
 - Independent "La Fonera" devices are not produced, but still can be connected.
    * The question how long independent network will be supported. The last devices out of 2y support in 2020.
    * Still we can install it in Armenia or currently in UK.

 - Official FON passes
    * Daily / Weekly / Monthly passes (expensive in DE/UK)
        - Expensive (5 / 20 / 30 EUR in DE)
        - Not available in Germany (only trough provider)
    * Can't be bought from the different country
        - Offered from Mobile App only (after connecting to FON hotpost) and bound to the location
    * Limit on number of connected devices
        - Most countries: 3 devices (not possible in different countries)
        - Germany: single device
    
 - The provider networks:
    * Free Fon with Broadband and Mobile contracts (which up to now have had bad conditions)
    * WiFi passes (similar to FON passes), mostly also location bound
    * WiFi subscriptions (could be cheaper and probably managed from different country)
    
 - Variants
    * BTWifi (UK)       Year subscription, 15 EUR / month
    * Brasilia          Free with commercials, but impossible without Brasilian phone number (and probably neither then)
