The best values in MVNOs if you have more than one line. While the top-end unlimited plan with 30GB of hotspot data and HD video streaming starts a little steep at just under $50 per month, you can add up to four additional lines for $25 per month each. You could also choose from three other plans with 5GB, 8GB, or 40GB data allotment starting at $25, $30, and $40 per month.

Even if you're not on an unlimited plan, you'll only pay for the data you use, and you'll never pay for more than 6GB of data, thanks to Bill Protection. After 15GB on the Flexible plan, your data speeds will slow, but you can always add more high-speed data at that time for $10 per GB. On the unlimited plans, your speeds will slow after 22GB of use.
