How Ultra Mobile 24GB Scores

Customer experience 7.0

Pricing: the best data-per-dollar in the lineup

24GB runs $39 monthly, $35 on three months, $26.35 on six and $18.90 on twelve. At the annual rate that's roughly 79 cents per GB — the cheapest ratio Ultra sells, and cheaper per GB than any of its unlimited tiers become at realistic usage.

Renewal is $27/mo, the largest absolute step-up among the capped tiers. Even so it stays well below the $39 monthly rate, and below what Ultra Unlimited renews at ($34).

What You Get

✓24GB at $18.90/mo on a year — the most data per dollar in the lineup
✓First tier with 5GB Go Roam data in Mexico and Canada
✓Unlimited talk to 90+ countries and text to 200+
✓Cheaper than Ultra Unlimited by $4.90/mo with data most people won't exhaust
✓Hotspot can use the full 24GB, unlike Unlimited's 10GB cap
✓No credit check, no contract, no termination fee

What You Don't Get

−The $18.90 rate is introductory — it renews at $27/mo
−$39 month-to-month is poor value against unlimited plans at that price
−Still a hard cap; heavy months mean add-ons
−Taxes and fees are extra
−Video is capped around 480p
−Deprioritization can bite above 35GB across Ultra's network

How Ultra Mobile 24GB compares

24GB against Ultra Unlimited is the most interesting comparison in the lineup, and the cap usually wins.

Feature 24GB Ultra Unlimited
Annual term rate $18.90/mo $23.80/mo
Monthly rate $39/mo $49/mo
Renews at $27/mo $34/mo
Data 24GB Unlimited
Hotspot Full 24GB available Capped at 10GB
Mexico & Canada data 5GB Go Roam 5GB Go Roam

Who should choose Ultra Mobile 24GB

✓You use 12–24GB a month and want the best rate per GB
✓You tether and want the hotspot to draw from a big pool, not a 10GB cap
✓You travel to Mexico or Canada and want roaming data, not just calls
✓You call internationally — 90+ countries included
✓You can prepay a year

Who should skip it

−You want month-to-month; $39 buys unlimited elsewhere
−You genuinely use more than 24GB — take Unlimited or Unlimited+
−You want all-in pricing; taxes and fees are extra
−You stream a lot of cellular video; Ultra caps around 480p
−You want a big dedicated hotspot allowance — that's Unlimited+ at 25GB

Final Verdict

The tier to buy if 12GB isn't enough, and the one that makes Ultra Unlimited hard to recommend. 24GB covers heavy real-world use, hotspot draws from the whole allowance rather than a 10GB sub-cap, and it's the first tier to include 5GB of roaming data in Mexico and Canada — genuinely useful if you cross the border. It's $4.90/mo less than Unlimited on the same term. Buy Unlimited only if you truly don't want to think about data at all.

Frequently asked questions

How much is Ultra Mobile's 24GB plan?

$39/mo month-to-month, $35 on three months, $26.35 on six and $18.90/mo on twelve. The annual rate renews at $27/mo. Taxes and fees are extra.

Does it include Mexico and Canada roaming data?

Yes — 5GB of Go Roam data, and this is the cheapest Ultra tier that includes it. Lower tiers include unlimited talk and text there but no data.

Is 24GB better value than Ultra Unlimited?

For most people, yes. It's $4.90/mo less on an annual term, and its hotspot can use the full 24GB where Unlimited caps hotspot at 10GB.

What does it renew at?

$27/mo on the annual term — still well under the $39 month-to-month rate.

Can I use all 24GB for hotspot?

Yes. Capped tiers share one pool between phone and hotspot, so nothing artificially limits tethering below the plan allowance.
