I don't have one, but I need to get one for emergencies.
We had a bad snowstorm a couple of years ago and the power went out for five days. Phone lines, too.
Our house uses central heat for warmth.
Well, we try to leave to spend the night with my brother and the car won't start. (yikes!)
So, we had no phone, no heat, not much food, and a few batteries for our lanterns.
Luckily, we had a couple of little foot tall butane indoor heaters that put out enough warmth to heat about a six foot circle.
I want a cellphone just in case it happens again and then maybe we can get a little help.
I don't know what I'm waiting for, either. (just a big procrastinator, I suppose)
Cellphones, in general, are a good thing, imo.
