H2O Multi-Line Unlimited, at $50 for 2 lines
This is the plan H2O built for exactly this situation, and it starts at two lines rather than four. Both lines get 60GB at full speed (not shared, each) plus 5GB of hotspot and unlimited calling to 100+ countries. There is no overage: past the allowance speeds reduce and service continues. At $50 for the pair it undercuts most single lines from the major carriers.
The catch: Taxes are extra, roughly $1.60 to $3.00 a line before state tax, so budget nearer $55. The rate requires two or more lines on one account. There is no single-line equivalent at this price.
Read our full review →Every price here is the cost of two lines, not one. Watch for plans where the discount only starts at three or four lines — Boost's $25 tier, Cricket's 12-Month Unlimited and Visible's flat-rate plans all have no two-line discount at all, which does not make them bad, just not cheaper as a pair.
Top picks — the short version
The best plan for two lines costs about $50 a month for the pair. The choice comes down to whether you want each line to have its own big data allowance, or the lowest possible combined bill.
