@BitFlipper: I bought my phone without a service, so the 2 year scenario doesn't fit to my situation.

Is my situation unusual? Is a mobile phone service worthwhile? I rarely even use my landline phone, (parents phone actually) I probably average once every 2 or 3 months. Microsoft phoned me the other day to inquire about my Visual Studio download and usage. I won't be buying a Windows phone or Surface anytime soon as I have to spend my money on a liscence for VS pro and I have had an extremely low income for several years as I work on my research and development for some of the most complex software you can imagine.
