Ultra Mobile sells prepaid phone plans on the T-Mobile 5G network, each with unlimited talk to 90+ international destinations, plus phones, eSIM and SIM cards.
You pay for plans upfront, and money paid generally isn't refunded if you cancel. Pick the term length carefully, because the lower multi-month rates come with a longer commitment.
Ultra Mobile plans come in 4GB, 12GB and Unlimited sizes, and each includes global texting, mobile hotspot, Wi-Fi calling and unlimited talk and text in Mexico and Canada, with international calling and roaming credits on top. Customers can bring their own phone or buy a new one, and choose between an eSIM and a 3-in-1 SIM card.
The carrier sells online and through retail stores, with a store locator on its site, and its customer care team works in English, Spanish and Mandarin; the website itself also has a Spanish version. A family plan bundles several Unlimited lines, a 30-day Mexico roaming pass adds data for trips south of the border, and a refer-a-friend program is offered. Plans have to be activated within 45 days of purchase.

More about shopping at Ultra Mobile
Plans
Choose 4GB, 12GB or Unlimited, paid upfront for a single month or for 3, 6 or 12 months; the 4GB plan is $19 a month.
Contract terms
There's no contract and no early termination fee, but taxes and fees are added on top of the plan price.
Refunds
Cancelled plans aren't refunded unless the law or the Plan Refund Policy requires it; if Ultra ends a multi-month plan, unused 30-day periods come back pro rata.
Auto Renew discount
1-month plans get 10% off with Auto Renew, which you can cancel anytime at least 24 hours before the cycle ends.
Referrals
You get a $25 renewal credit and your friend a $25 credit once they activate; both expire 90 days after the code is issued.
Mexico roaming
Heading south? A 5GB Mexico data roaming pass covers 30 days and costs $5.
Activation deadline
A purchased plan must be activated within 45 days, so don't buy a plan long before you need the line.
Ultra Mobile's promotions can't be combined with each other and have no cash value, so each plan purchase carries one offer at moSt. That matters most for the Auto Renew saving: the 10% off 1-month plans doesn't combine with other offers, so a new-customer multi-month price and Auto Renew won't stack.
Weigh the flexibility of a single month against the lower monthly rate of paying upfront.
If a friend referred you, use their code when you activate, because the $25 credit only arrives once your plan is active.
Plans also need activating within 45 days of purchase, so time the purchase to your switch.
If your Ultra Mobile code doesn't work
Combining offers: Promotional offers can't be combined with other offers and have no cash value.
New customers only: "30% Off Ultra Mobile Orders" is for a first order.
End date: "30% Off" ends Feb 1, 2027; "15% Off Ultra Unlimited & Plan Sim Kit (plan 1 Month)" ends Nov 17, 2026.
Turning on Auto Renew takes 10% off a 1-month plan, and you can switch it off at least 24 hours before the cycle ends.
Referring friends earns a $25 renewal credit each time one activates, but use it within 90 days.
Paying for 3, 6 or 12 months upfront lowers the monthly rate in the new-customer offers above.
Frequent travelers to Mexico can add the 5GB roaming pass for $5 rather than paying for a bigger plan.
