3. Go data-free: Kick it old-school style by dropping your data plan altogether. This option may not be available if you've purchased a smartphone that requires a data plan; but for some consumers it's a sensible move.

And it is possible: When my suffered a fatal fall recently, I went back to my elderly flip phone and relied on an for apps and Internet services. When I wanted to check email or browse the Web, it was Wi-Fi only.

My pockets were heavier, in part because I was carrying two devices around, but also because my pockets had more cash in them thanks to my lower monthly bill.

How much can I save? $15 to $50 a month, or more.

4. Go on a data diet: Not ready to opt out of a data plan completely? Try cutting back instead.
