How Ultra Mobile 4GB Scores

We scored Ultra Mobile 4GB against the same four pillars we use for every plan. Here’s how it broke down.

Value for money 9.0
Network & speed 8.0
Hotspot & features 6.2
Customer experience 7.0

Pricing: the annual rate is the only interesting one

4GB runs $19 monthly, $16 on three months, $12.75 on six and $9.10 on twelve. Bought by the month it's poor value — plenty of carriers sell more data for $19. Bought by the year it's one of the cheapest legitimate smartphone lines in the US.

The renewal matters here more than on other tiers because the gap is proportionally large: $9.10 becomes $13/mo after the first year. That's still under monthly pricing, but it's a 43% increase, so plan for it.

What You Get

✓$9.10/mo on an annual term — under ten dollars for a real smartphone line
✓Unlimited international calling to 90+ countries, same as every tier
✓Unlimited talk and text in Mexico and Canada included
✓4GB is workable for a Wi-Fi-heavy user who still needs maps and messaging
✓Sold month-to-month too, unlike Talk & Text
✓No credit check, no contract, no termination fee

What You Don't Get

−The $9.10 rate is introductory — it renews at $13/mo
−4GB goes fast if you stream or navigate on cellular daily
−Monthly pricing is $19, more than double the annual rate
−Taxes and fees extra, unlike Cricket or Metro
−Hotspot shares the 4GB rather than having its own allowance
−No Mexico or Canada roaming data below the 24GB tier

How Ultra Mobile 4GB compares

The decision is 4GB against 8GB, and on an annual term the gap is smaller than the headline prices suggest.

Feature 4GB Ultra Mobile 8GB
Annual term rate $9.10/mo $11.90/mo
Monthly rate $19/mo $24/mo
Renews at $13/mo $17/mo
Data 4GB 8GB

International calling 90+ countries 90+ countries

Who should choose Ultra Mobile 4GB

✓You call internationally and want the cheapest line that includes it
✓You use about 2–4GB a month and are mostly on Wi-Fi
✓You can prepay a year to get the sub-$10 rate
✓You want T-Mobile coverage on a budget bill
✓You travel to Mexico or Canada and mainly need talk and text there

Who should skip it

−You want month-to-month flexibility — that costs $19, not $9.10
−You use more than about 4GB; 8GB costs $2.80/mo more on a year
−You tether — hotspot comes out of the 4GB
−You want all-in pricing; taxes and fees are extra
−You stream video on cellular; Ultra caps around 480p

Final Verdict

The right entry point at Ultra and a better buy than Talk & Text for almost everyone — eight times the data for less money on a year. 4GB is enough if your phone spends most of its day on Wi-Fi and you mainly need maps, messaging and calls, and the unlimited calling to 90+ countries that comes with it is the real draw. If you regularly use cellular data for anything visual, step up: 8GB is only $2.80/mo more on the same term.
