I always turn off my wifi when entering shopping malls that is IF I carry my Samsung Galaxy S3 android. Most free connections are very slow.....so itīs useless anyway imho. I also not have any 3G plan...way to expensive in paraguay. So I only use wifi.
But most of the times when I go to town I take my old Nokia brick phone with me.(still works like a charm)....you know were I live people get robbed (or worse!) if they see a nice smartphone..!! I avoid to flash it arround in public.
I also have an old Motorola V3 Razr clamshell.....still works....
But I donīt break it everytime I make a phone call...like on TV...hehehehehe
besides that...If i go shopping...I look at things and other people and donīt stare 55 min from every hour at my smart phone....;-)
