Pricing: an intro rate, then a different plan

$45 buys the first three months, $15/mo, and then it renews at $35/mo. Signup is online only. You get 30GB at up to 3 Mbps and then 1.5 Mbps for the rest of the cycle. 3 Mbps handles SD video, music, maps and browsing perfectly well. It does not handle HD streaming, large downloads or video calls comfortably. A 5GB hotspot is available as a $10/mo add-on.

Judge it on the $35, not the $15. At that price AT&T's own 12-month plan is about $20/mo with priority data, no speed cap on its 16GB, and a 10GB hotspot included: $15 a month less for materially more plan, if you can put $240 down at once.

What You Get, and What You Don't

What we like
✓$15/mo for the first three months is the cheapest route onto AT&T's own network
✓30GB before the speed drops further: a generous allowance
✓Unlimited talk, text and international texting to 230+ countries
✓25GB of data in Mexico and Canada
✓No credit check, no contract, no termination fees
Where it has limits
✕Hard 3 Mbps ceiling: this is the defining limitation
✕No hotspot included: the 5GB add-on is $10/mo on top
✕Deprioritized on top of the speed cap
✕The price jumps to $35 after three months
✕The 12-month plan is $15/mo cheaper at that point, with priority data and a 10GB hotspot
✕Online signup only: a store can't sell it to you
✕Taxes and fees are extra

Unlimited ($35) vs. 12-Month ($20/mo)

The awkward comparison is against AT&T's own annual plan, which costs far less once the intro ends.

Choose it if

✓You want the cheapest monthly AT&T line and can live at 3 Mbps
✓You stream at SD quality and browse rather than download
✓You want a large 30GB allowance before further slowing
✓You don't tether at all
✓You travel to Mexico or Canada
✓You want month-to-month rather than an annual commitment

Skip it if

✕You can prepay a year, the 12-month plan is cheaper and better
✕You tether; there's no hotspot on this tier
✕You want HD video or fast downloads: 3 Mbps prevents both
✕You want to sign up in a store
✕You want all-in pricing; taxes and fees are extra

Final Verdict

6.6/10 · AT&T Prepaid Unlimited (online only)

A good three months and a mediocre fourth. At $15/mo, 30GB at 3 Mbps on AT&T's own towers is a genuinely cheap way onto the network, and 3 Mbps is more usable than the throttles most budget carriers impose. At the $35 it renews to, AT&T undercuts it with its own annual plan at about $20/mo: uncapped on its first 16GB, with a 10GB hotspot included. Take the intro, then decide again in month four.

Consider instead: AT&T Prepaid 12-Month Unlimited. Fifteen dollars a month less than the renewal rate, with priority data instead of a 3 Mbps cap and a 10GB hotspot instead of none. Better in every way if you can prepay the year.

Frequently Asked Questions

How much is AT&T Prepaid's online-only unlimited plan?

$45 for the first three months, about $15/mo, then $35/mo plus taxes and fees. Signup is online only. It includes 30GB at up to 3 Mbps, then 1.5 Mbps.

What does a 3 Mbps cap actually feel like?

Fine for SD video, music, maps, social and browsing. Not enough for HD streaming, big downloads or comfortable video calls.

Does it include hotspot?

No. Neither this plan nor Unlimited Saver includes any hotspot. The 12-month plan and Enhanced Plus include 10GB; Ultra includes 30GB.

Is it better than Unlimited Saver at $35?

They now cost the same $35 and carry the same 30GB at 3 Mbps. This plan adds Mexico and Canada roaming and a three-month intro rate; Saver's only edge is that it isn't restricted to online signup.

Why is it online only?

AT&T restricts this rate to its online channel. If you need to buy in a store, Unlimited Saver is the equivalent plan at $35.
