Pre-paid means you don’t end up tied to a contract for a year or two, you just use the plan for as much as you want.
The new offers range from 100MB to 1GB, which will cost you from $15 all the way to $50 a month. To complicate matters, though, the carriers has limited the lowest tier, 100MB, to last for a mere 7 days, while the mid-tier 300MB option is good for two weeks and only the 1GB data allowance would last you a whole month.
