I dont have a cellphone either, but my fostermother recently got a new plan. She pays 7.50 euro's a month for 100 minutes and.... a certain amount of texts, not sure how much. It's a one year plan.
you can also chose to just buy a phone and then not get a plan but just buy credit. Comparatively, that is more expensive though. However if you only plan to use it for emergencies, it may be cheaper in the end.
