some one earlier was looking for cheap phones. Recently I have seen a number of really cheap phones, some of which seem highly capable, for under $10, including one Android with a 6" screen (from Hong Kong) but they all lack 4g and some lack 3g.I know an elderly lady that tends to loose phones (or grandson steals them). I'm looking at a Trackphone Samsung 3g flip phone, very basic, no camera, and a Best Buy ATT go phone, also I think 3g. The trackphone has a double the minutes card. Thinking about one or the other, since I ASSUME they still work in the emergency mode. If ATT had double minutes that would be appealing, assuming same minute price, so she could use as regular phone. CAN A 3G PHONE BE USABLE IN THE FUTURE? THANKS
