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.
Pricing: the annual rate is the only interesting one
4GB runs $19 monthly, $16 on three months, $15 on six and $13 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.
Ultra currently discounts this tier to $10/mo for new customers on any multi-month term — $30, $60 or $120 upfront. That covers the initial term only, after which the plan sits at its regular rate. It's a 43% increase, so plan for it.

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.

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.

How much is Ultra Mobile's 4GB plan?
$19/mo month-to-month, $16 on three months, $15 on six and $13/mo on twelve. New customers currently pay $10/mo on any multi-month term, for the initial term only. Taxes and fees are extra.
Is 4GB enough data?
For a Wi-Fi-heavy user doing maps, messaging, email and occasional browsing, yes. For daily streaming, social video or navigation on cellular, no — look at 8GB or 12GB.
Does it include international calling?
Yes — unlimited talk to 90+ international destinations and global text to 200+, on this tier and every other Ultra plan.
What does it renew at?
$13/mo is the regular twelve-month rate. The $10 new-customer offer applies to the initial term only.
Is it better than Ultra's Talk & Text plan?
At the regular twelve-month rate Talk & Text is cheaper — $10 against $13 — but it carries 500MB against 4GB. With Ultra's current $10 new-customer offer the two cost the same, which makes 4GB the clear pick.
