I use my phone very little for phone calls. Mostly it's my pocket notebook, navigator and my window to the web. It's the computer I can have with me everywhere. Because I use it so little for phone calls, I wonder if I would be better off with a pre-paid phone plan. Let's see.
I'm currently on a $29 plan with 3, who were purchased by Vodafone in the middle of my contract. Over the 24 months of that plan, my total cost is about $696. My included call credit ($180/month) easily covers my calls and texts. Every two years, I sign up for a new plan mostly to get a new handset for free, so that would have to be part of a pre-paid budget too.
Now how would a prepaid plan with a BYO handset work? The new handset I currently want is the Nexus 4, for $400. If I had to buy one every 24 months, that leaves just $296 for calls and data over the two years, or just more than $12 per month. I'd have to survive on a $30 top-up only four times per year to make a pre-paid phone more cost-effective than a 24-month plan. I use more than that, though I do use fairly little.
So what about if I were to sell my old phone after 6 months and buy a new one? Well, that's much worse. Even if I were able to reclaim 75% of the original price and the prices of new phones didn't go up, I'd still be spending an extra $100 every 6 months, which is a bad deal, price-wise. It's the same cost as replacing the $400 phone every two years. The only difference is that the average age of my phone would go down, and that doesn't matter very much to me.

PS - I've never had a prepaid phone, so I might be missing some important factor.
PPS - If not, then they're terrible value for me.
