Does Mint Mobile Work in Mexico? Pass Prices, Setup and Limits

Need more data than a pass holds, or staying for months? A HelloRoam eSIM for Mexico can run your maps and ride apps on Mexican networks while your Mint number stays on the phone.

We checked the Mint prices and rules in this guide on Mint's own pages on November 8 and 9, 2026, and in Mint and T-Mobile announcements and an FCC filing on November 8, 2026. Mint says its international rates and destinations can change at any time without notice, so look at its International Roaming page again before you cross the border.

Mint Mobile in Mexico runs on a Minternational Pass

Your plan's own data stays home. Mint's plans include free roaming in Canada only, and Mint says that to use your service anywhere else abroad, you have to buy and activate a pass. Mint also asks you to check that your destination is eligible before you buy, so type Mexico into the country checker on its International Roaming page first.

Mint sells four passes. Each one starts when you activate it, not when you buy it.

You may have read that your data stops completely once the high-speed part runs out. Mint's own pages say otherwise for the longer passes: the 3-Day and 10-Day passes come with unlimited data, and Mint says speeds drop after the high-speed data is used. Mint gives no figure for that lower speed. The 1-Day Pass lists 1 GB and no unlimited data, so plan on that gigabyte being your day's data.

To buy a pass, you need an active Mint plan that was activated in the US, and Mint's trial plans can't add one. The same passes work in 180+ countries, and Canada gets free roaming instead.

Mint's free calls to Mexico only count from the US

Mint includes free calls to Mexico, Canada and the UK on all its plans. That's the line that trips people up. Mint defines international calling as a call you make from the US to an international number. Using your phone while you're in Mexico is roaming, which Mint defines as using data or calling or texting a US or international number while you're abroad.

So the free calls help before you leave. Call your hotel, your tour company or friends in Mexico from home at no extra cost, and keep your pass minutes for the trip. For how roaming works across US carriers, see what international roaming means.

Once you're in Mexico, Mint's rules work like this:

• Calling a Mexican number, such as a restaurant or your driver, uses pass minutes, the same as calling home.
• Receiving texts is free. Replying uses texts from your pass.
• With Wi-Fi Calling on and your phone on Wi-Fi, calls and texts to US numbers are free and don't come out of your pass.
• Calls to Mint's Care team don't use pass minutes, and using the Mint app doesn't use pass data.

Save Mexican numbers in your phone as +52 and the 10-digit number. That's the format for calls from abroad in the Federal Telecommunications Institute's guide to Mexico's 10-digit numbers, the same for cell phones and landlines. Mexico's national emergency number is 911.

Mint runs on T-Mobile, but T-Mobile's Mexico roaming doesn't carry over

Mint runs on T-Mobile's network. T-Mobile completed its purchase of Mint's parent company, Ka'ena, on May 1, 2024, and said the deal locks in Mint's connection to its 5G network, according to T-Mobile's announcement of the deal. T-Mobile's Mexico page advertises its own plans with "No roaming charges. No setup required."

That doesn't carry over to Mint. T-Mobile said the brands would keep operating on their own, and the roaming perk it announced for Mint customers was free roaming in Canada. In October 2026, Mint's list of what every plan includes still had free roaming in Canada only. If someone in your group is on T-Mobile, their plan may already include Mexico while you buy a pass.

What a Mexico trip costs on Mint, from a border day trip to a month

A pass's time counts in hours from the moment you activate it: 24, 72, 240 or 720. Activating a new pass ends the active one right away, even with data or minutes left. So the cheapest setup is a run of passes whose hours add up to your trip, each started after the last one ends.

At Mint's prices, a Mexico trip adds these pass costs to your monthly Mint plan.

Four days is the close call. A 3-Day Pass and a 1-Day Pass cost $15 for 4 GB, but $5 more buys a 10-Day Pass with 10 GB. From 5 days up to 10, the 10-Day Pass wins, since a 3-Day Pass plus two 1-Day passes costs the same $20 for half the data.

You can keep up to two passes stored at once, and Mint charges you when you buy. Unused passes expire 360 days after purchase, so buy close to the trip. On a 30-day stay, buy the third pass once the first one is running.

Not sure how much data a day you'll use? Estimate your Mexico data use before you pick a pass.

How to turn on your Mint pass when you land in Mexico

1. Buy the pass before you fly: in the Mint app under Account, then Minternational Pass; on Mint's website under Add Ons; or by texting GO to 6700 and replying GO1DAY, GO3DAY or GO10DAY. Buying by text needs a saved payment method with consent checked, or money in your Mint wallet.
2. Activate it once you're in Mexico. Mint texts you on arrival so you can switch on a stored pass. You can also tap Activate under My Current Passes in the app, use Your Passes on the website, or text ACTIVATE to 6700 to start your earliest stored pass.
3. Turn on Data Roaming, which Mint says the 1-Day, 3-Day and 10-Day passes need. On an iPhone, go to Settings, then Cellular, then Cellular Data Options. With two lines, tap your Mint number first, as Apple's roaming steps show.
4. Check what's left by texting GOROAM to 6700, or in the app under My Current Passes.

Time the start. A 10-Day Pass you activate at 3:00 PM on arrival day runs out at 3:00 PM ten days later, so start it when you first need data, not the night before you fly.

Mint coverage in Mexico, and what to check when it won't connect

Mint's checker takes a country, not a city, so it says nothing about coverage in the places you'll visit. The Mint pages we read don't name the Mexican network a pass connects to. Mint says your phone switches between 5G and 4G LTE, whichever is stronger, and that this varies by location. Its roaming page also notes that a capable device is required.

If nothing connects, check these two things first:

• Confirm the pass shows as active and hasn't expired: look under My Current Passes in the app, or text GOROAM to 6700.
• Check that Data Roaming is on in your phone's settings, which the 1-Day, 3-Day and 10-Day passes need.

Still stuck? Mint's International Roaming page links to its full troubleshooting guide, and calls to Mint's Care team don't use your pass minutes.

Mint's passes don't cover cruises, and long stays take pass after pass

Mint says Minternational Passes can't be used on cruises or airlines. On a cruise that calls at Mexican ports, start a pass only once you're ashore, since its hours start counting the moment you activate it.

Long stays are the other limit. For long trips, Mint pitches its 30-Day No Data Pass at people "on extended leave", and that pass carries no data. For data you'd keep buying passes, at $60 for 30 days. None of the pages we read gives a day limit.

Wintering in Baja or spending a few months in Mexico City? Use a Mexican SIM or a travel eSIM for the long haul. If you go local, know that Mexico now ties every mobile line to its owner. Telcel says every line taken out since January 9, 2026, must be registered with official photo ID and a CURP. For foreigners, rules in force since June 30, 2026, accept a passport, a CURP for foreigners or an immigration (INM) visitor or resident card that shows a CURP. Mexico's telecom regulator explains the mobile line registration rules in Spanish. If you're basing yourself in the capital, our Mexico City eSIM is a data-only option you can set up before you leave.

Keep your Mint number in Mexico and move your data to a travel eSIM

Mint's passes make sense for short trips, for calls and texts on your own number, and for a week or so of everyday data. A travel eSIM tends to fit better in three cases: you'll use more than about 1 GB a day (the high-speed share of a 10-Day Pass), the trip runs past 10 days, or you're staying for months. Here's how travel eSIMs and roaming compare in general.

As of November 8, 2026, our plan catalog lists Telcel and AT&T Mexico for every HelloRoam Mexico plan, and the plans carry data only. Networks can change, so the plan page shows the current ones. A plan's days start when the eSIM first connects to a network in Mexico, so you can install it at home.

Compare like for like before you buy. On the day we checked, Mint's 10-Day Pass cost less than our 10 GB Mexico plan, while our 3 GB Mexico plan cost less than Mint's 3-Day Pass and lasts longer, though that pass adds minutes, texts and slower data after its 3 GB. For 30 days, Mint's route is three 10-Day passes at $60 for 30 GB, so price a month-long Mexico plan against that.

Want to keep calling and texting on your Mint number too? Pair the eSIM's data with Mint's 30-Day No Data Pass, which gives your own number 100 minutes and 100 texts for $5. Wi-Fi Calling still covers calls to US numbers whenever you're on Wi-Fi.

Your phone has to be unlocked first. As a condition of buying Mint, T-Mobile agreed with the FCC to unlock Mint phones that have been on its network for at least 60 days and aren't on a financing plan. On an iPhone, "No SIM Restrictions" next to Carrier Lock under Settings, General, About means it's unlocked, as Apple's page on using eSIM abroad explains. Check that your model is on our list of phones that support travel eSIMs, too.

Then, in Mexico, set the phone to use the eSIM for data and leave your Mint line on:

• On an iPhone, go to Settings, then Cellular, then Cellular Data, and choose the travel eSIM.
• On a Google Pixel, go to Settings, then Network & internet, then SIMs, and pick the travel eSIM under Mobile data. Google's dual SIM help says only one SIM can be the default for data.
• Turn on Data Roaming for the travel eSIM's line.
• Keep Allow Cellular Data Switching off. Apple's Dual SIM guide says turning it on lets your iPhone use cellular data from both plans.

We sell travel eSIMs, so weigh our view with that in mind. Here's how we handle being a seller, and our full comparison with Mint goes country by country.
