Here's some help determining which plan will work for you, even if you don't know how many megabytes are in a gigabyte.
Verizon hasn't said what its plans will look like. But because AT&T introduced capped data plans a year ago and T-Mobile USA eliminated its unlimited data plan in May, this is well-trod ground.
The new Verizon plans will most likely apply only to new customers or people trading up to smartphones.
They could also apply to smartphone users buying new phones.
For AT&T, the introduction of data caps has gone quite well, but some customers are complaining because their data usage reports are hard to decipher. AT&T says 90 percent of its customers on capped plans stay within the limits, but it won't say how much those who go over end up paying, on average.
Verizon now charges $30 a month for an unlimited smartphone data plan.
Here's a look at potential caps:
•Less than 200 megabytes per month.
It's possible Verizon could have an entry-level plan for $10 or so per month with a very low data limit, such as 75 megabytes per month. But any plan with less than 200 megabytes per month should be considered mainly a tease. It will be very hard to stay under the limit.
•200 megabytes per month.
This is a popular size, offered by both AT&T ($15 per month) and T-Mobile ($10). When it introduced this plan, AT&T said 65 percent of its subscribers consumed less than 200 megabytes.
T-Mobile charges $30 for this tier, or $10 more than the 2-gigabyte plan. Verizon would likely charge substantially more. This would be for those who spend a lot of time on their phones. Laptop cards generally come with this data limit.
What if you don't want to bother with any of this?
Sprint Nextel Corp. still offers unlimited data, seeing it as a crucial way to keep and attract customers who are tempted by an iPhone at Verizon or AT&T. However, offering an all-you-can-eat data buffet gets expensive. Sprint raised the fees for all its smartphones by $10 per month this winter to $30.
