How multi-line pricing works
Postpaid carriers lower the per-line price as you add lines, so four lines often cost less than twice the price of two.
Prepaid brands more often charge a flat per-line price, which can still beat a discounted postpaid family plan.
Mixing plans across a household
Not everyone in a household needs the same plan. Pairing one unlimited line with three small capped lines is frequently the cheapest correct answer.
Separate accounts on different carriers can save more than a bundled family plan, at the cost of managing more than one bill.
