Ultra Mobile review (2026): the plan for calling abroad
What Ultra Mobile's plans cost, how its international calling works, and when it beats Mint Mobile on the same T-Mobile network.
Ultra Mobile is a prepaid carrier on T-Mobile's network built for people who call abroad: every plan includes unlimited calls to 90+ countries and talk and text in Mexico and Canada. Plans start at $19 for 4GB; Unlimited is $49 a month, or $34 a month on a 12-month plan, with taxes extra. If you only call within the US, Mint is cheaper. See Ultra Mobile plans.

International calling
This is why people choose Ultra. Every plan includes unlimited calls from the US to more than 90 countries, including Mexico, India, China and much of Latin America, plus international texting to 200+ countries. Plans also include talk and text while you are in Mexico and Canada. Ultra adds pay-as-you-go credit for countries outside the list.
If you spend $10 to $20 a month on calling cards or an international add-on with another carrier, Ultra's 4GB plan at $19 can cost less than a domestic plan plus the add-on.
Ultra Mobile vs. Mint Mobile
Both use T-Mobile's network. Mint Unlimited is $30 a month on a 12-month plan and includes calls to Mexico and Canada only. Ultra Unlimited is $34 a month on the same term, or $25 in the first year for new customers, and adds calls to 90+ countries. Pick Mint for domestic use and Ultra if you call abroad.
Traveling rather than calling abroad? See phone plans for Canada and Mexico and the best travel eSIMs. For cheap unlimited plans without international calling, compare Visible, Mint and US Mobile.
Coverage and speeds
Ultra uses T-Mobile's 5G and 4G LTE towers, so coverage matches T-Mobile's map. Ultra lines get lower priority than T-Mobile's own customers, so speeds can drop at busy times, and Ultra has said speeds may slow during congestion after 35GB of use in a month on Unlimited. Video streams at 480p, which looks fine on a phone screen.

Who should skip Ultra
Ultra is the wrong pick for some people.
- People who only call within the US: Mint Mobile costs less on the same network.
- Verizon or AT&T customers with weak T-Mobile coverage at home: try US Mobile, which lets you pick the network.
- Heavy hotspot users: even Unlimited+ caps hotspot at 20GB.
If you rarely call abroad, Straight Talk or Visible, Mint or US Mobile will cost less for the same data.
