I have two telephones.
My portable one is a basic DORO 6520.
Rated at 3G, it supposedly can be linked to the Internet but I have not done that. I keep it on PAYG, and it costs me £30 to £40 a year, generally, in call fees. A display area only 44mm wide X 58 high is hardly going to be any use for web-sites!
Its primary function, as designed, is voice telephony. I wonder if that revolutionary idea will catch on?
[In case you are wondering how I use SW, on a PC on full broadband service that also holds my land-line telephone. I need a proper computer with standard keyboard, mouse, printer and 21-inch screen for most of my IT purposes, before Internet use.]
