The plan to buy at AT&T Prepaid — 16GB of priority data and a 10GB hotspot for about twenty dollars a month, which is less than the two monthly tiers that offer neither.

How AT&T Prepaid 12-Month Unlimited Scores

We scored AT&T Prepaid 12-Month Unlimited against the same four pillars we use for every plan. Here’s how it broke down.

Value for money 9.2

Pricing: the cheapest tier is also the best one

$240 once covers twelve months — about $20/mo — with 16GB of priority data, a 10GB hotspot, and unlimited data at reduced speed after the 16GB. Taxes and fees are extra but small in absolute terms.

The reason this is the pick is what sits above it. The $25 online-only plan and the $35 Unlimited Saver both cap you at 3 Mbps with no hotspot at all, and both are deprioritized. This plan costs less than either and is materially better on every axis that matters. The only thing you give up is monthly flexibility.

What You Get

Cheaper than the $25 and $35 monthly tiers while beating both outright
Priority data, where those tiers are deprioritized and capped at 3 Mbps
10GB hotspot, where those tiers include none at all
16GB of high-speed data then unlimited at reduced speed — no hard cutoff
Unlimited talk, text and 16GB of data in Mexico and Canada
Native AT&T network with no credit check or contract

What You Don't Get

$240 has to be paid up front for the year
16GB of priority data is modest for a heavy user
480p video, like most of the prepaid lineup
Taxes and fees are extra on top of the $240
Not eligible for the multi-line discounts, which need $45/line
A year is a long commitment on a prepaid brand

Who should choose AT&T Prepaid 12-Month Unlimited

You want AT&T's own network at the lowest sensible price
You can pay $240 up front
You use up to about 16GB of high-speed data a month
You tether occasionally — 10GB covers email and browsing
You want data that holds up in congestion rather than a 3 Mbps ceiling
You travel to Mexico or Canada

Who should skip it

You can't or won't prepay a year
You need a big hotspot — Ultra's 30GB is the tier for that
You're building a family plan; multi-line discounts need $45/line
You want HD video, which is Ultra only
You want all-in pricing; taxes and fees are extra

Final Verdict

The best plan in AT&T Prepaid's lineup and one of the better annual plans in US prepaid. Twenty dollars a month for 16GB of priority data, a 10GB hotspot and native AT&T coverage is strong on its own — and the fact that it undercuts two monthly tiers that are speed-capped with no hotspot makes it the obvious choice. The condition is real, though: $240 up front, and no refund path if you move on in month three.

Frequently asked questions

How much is AT&T Prepaid's 12-month plan?

$240 paid once for twelve months, about $20/mo, plus taxes and fees. It includes 16GB of priority data a month and a 10GB hotspot.

Why is it better than the $25 or $35 monthly plans?

Both of those are deprioritized, capped at 3 Mbps, and include no hotspot. This plan has priority data, no speed cap on its 16GB, and a 10GB hotspot — for less money.

What happens after 16GB?

Data continues at reduced speed for the rest of the month rather than stopping. The 16GB allowance renews each month across the twelve-month term.

Does it work in Mexico and Canada?

Yes — unlimited talk and text plus 16GB of data in both, at domestic rates.

Can I add family lines to it?

Not at a discount. AT&T Prepaid's multi-line discounts require a plan of $45/month or more per line, so Enhanced Plus is the entry point for families.
