Prepaid vs. postpaid internet

Prepaid internet stopped being a last resort

For years prepaid home internet meant slow DSL for people who couldn't pass a credit check. That changed when the big operators started selling prepaid versions of their own networks. Comcast's NOW brand runs on the same cable plant as Xfinity, and Mint's Home MINTernet runs on T-Mobile's 5G. Both are real, current-generation connections sold without a contract, a credit check, or a promotional rate that expires.

What makes them interesting isn't just the price — it's that the price is honest. When NOW says $30, taxes, government fees and the gateway are already inside that number, and it isn't an introductory rate. Compare that to a postpaid plan advertised at $30 that arrives as $48 after equipment rental and fees, then steps up to $70 in month 13.

What prepaid actually costs you

Three things. First, the ceiling: prepaid tiers stop well short of gigabit — 200 Mbps on NOW, up to about 400 on a good Mint signal — and uploads in particular are modest. If you push large files up or run a household of simultaneous video calls, this is the trade that will bother you.

Second, cash flow. Some prepaid plans bill monthly like anything else; others, Mint especially, want the whole term at checkout. A $45/mo figure that arrives as a $540 charge is a very different product from a $45 monthly bill, and the marketing rarely makes that distinction loudly.

Third, the small print around service. Prepaid plans often mean self-install only, refurbished equipment, a single outlet, mandatory autopay and paperless billing, and sometimes no money-back guarantee. None of that is unreasonable at the price, but it's worth knowing before the box arrives.

The prepaid plans worth knowing

When postpaid is still the right call

If you want fiber, you want postpaid — nobody sells symmetrical gigabit prepaid. The same goes for multi-gig tiers, professional upload speeds, bundled TV or mobile at a household price, and the promotional credits and reward cards that only exist on the postpaid side. Postpaid also lets you negotiate, which is a real lever: a customer of three years on a contract-free plan can usually talk their way to a better rate at renewal. Prepaid has no one to negotiate with.

The catch is that postpaid pricing requires management. You need to know when your promo ends, what the rate becomes, whether the equipment fee is avoidable, and whether the data cap applies to you. Our guide to reading your bill covers what to look for. If that sounds exhausting, that exhaustion is exactly what you're paying prepaid to avoid.

Five checks before you buy prepaid

The bottom line

Prepaid has quietly become the best-value way to buy ordinary home internet. If 200 Mbps covers your household — and for most households it does — paying $30 all-in with no credit check, no contract and no expiring promo is simply a better deal than a $30 promo that becomes $70. Buy postpaid when you need what only postpaid sells: fiber, gigabit speeds, real uploads, or a bundle.
