One day i might require a smart phone but never needed one yet. On holiday i take an ipad just to use the internet. My pay as you go phone uses 5 pound of credit in about 12 months. I top it up abroad just to receive urgent calls. My wife does have a smart phone so i suppose i could use that if really needed.
I make probably 6 calls using mobile phone in a year. Most use is Grandchildren phoning me for favours. Yesterday it was oil top up and tyre repair on a scooter. Slow air leak so tried one of the tyre repair spray cans.
