Compare with a travel eSIM for Europe — from $2.99arrow_forward

This site is not affiliated with T-Mobile; we sell eSIMs. How we compare

You may not need an eSIM. On Experience Beyond, a trip that stays inside the 15GB is already covered, and in Mexico and Canada both Beyond and More include data. Stay on T-Mobile then: same number, no second line to set up.

Two bill traps come first: a pass with no start date starts at once. In the 21 destinations T-Mobile leaves out, data is billed per use. We compare public packages; check your own plan.

What does your T-Mobile plan include abroad?

T-Mobile Experience Beyond gives up to 15GB of high-speed data abroad, Experience More up to 5GB, each then up to 256Kbps. Both work in 215+ countries and destinations; Essentials has no data abroad without a pass (checked on October 29, 2026, T-Mobile international roaming).

Plan prices for one line with AutoPay on October 29, 2026: Experience Beyond 2.0 is $100 (or $105 without AutoPay), Experience More 2.0 $85 ($90), Essentials 2.0 $60 ($65) and Essentials Saver 2.0 $50 ($55) (T-Mobile plans).

T-Mobile’s roaming page says: “Our plans are also international plans. Your phone just works when you arrive.” The same paragraph ends with “Not for extended international use”, with no day count, so we give none. If you will live abroad for weeks, ask T-Mobile what your line allows.

Calls are where T-Mobile’s pages disagree: the roaming page and the plan terms print different per-minute rates, and we print neither. In the 215+ destinations, calls are charged per minute, so check your plan before you dial. Calls and texts between the US, Mexico and Canada are a separate case (see below).

Texting abroad is included on every plan in the table. The data in an International Pass can also be used as a hotspot, T-Mobile says (T-Mobile International Pass).

This table covers postpaid plans. T-Mobile Prepaid lines run on separate plans, with a $5 Mexico and Canada add-on described below. For other destinations on a Prepaid line, check T-Mobile Prepaid.

Count your high-speed data before you count dollars. A normal week of cellular data at home, on your phone’s usage screen, tells you whether 5GB or 15GB is enough.

Two checks cost nothing. Find your destination on the list below. If you will use T-Mobile abroad, make sure data roaming is on for the T-Mobile line (turn data roaming on or off).

How much is the International Pass, and what does a trip cost?

T-Mobile sells three International Passes on qualifying plans (checked on October 29, 2026, T-Mobile International Pass). $10 buys 2GB for up to 24 hours and $50 buys 15GB for up to 10 days. $75 buys 30GB for up to 30 days, and every pass includes free calls.

You buy a pass in T-Life or My T-Mobile and choose its start date; without a date, the pass starts at once. One pass runs at a time, and activating a new one ends what is left of the old one.

When a pass’s high-speed data runs out, your plan’s roaming data takes over. On Essentials, that means up to 128Kbps until the pass ends.

The table below is our arithmetic: the smallest total from the three passes, for a line with no data abroad (Essentials). Passes run one at a time, so a longer trip chains them back to back.

At 14 days, a 10-day pass plus four 24-hour passes would cost $90, so the $75 30-day pass is the smaller total.

One more trap: T-Mobile’s cruise page still carries an FAQ with an older, cheaper 1-day pass. That text is stale; the International Pass page, $10 for 2GB, is the current price (T-Mobile cruises).

One row where we do not win: Experience Beyond on a 7-day trip. Its included 15GB costs $0 extra, so a travel eSIM adds cost for nothing unless you will pass 15GB.

Before you compare with our plans, check that your phone can take a second eSIM: Is my phone unlocked? and Does my phone support eSIM?

A T-Mobile pass puts data and free calls on your own number. Our plans in the table are data only: your US number stays on your main line.

The pass gives 15GB or 30GB where our plan gives 5GB or 10GB, and it includes calls. On most of our plans the days start when the eSIM first connects at your destination; check the activation rule shown on your plan. Compare the dollars per GB you will actually use, then work out your trip.

Which countries are included, and which are not?

T-Mobile’s support page lists “215+ supported countries and destinations (including the U.S. and Puerto Rico)”; 21 destinations get no plan benefits and no International Pass at all (checked on October 29, 2026, T-Mobile country list).

The International Pass countries list is the same list: every included destination takes plan data and the pass, and none of the 21 takes either. Names below are exactly as T-Mobile prints them.

Countries not included, 21 destinations in all: American Samoa, Ascension Island, Bhutan, Cook Islands, Cuba, Djibouti, Equatorial Guinea, Ethiopia, Falkland Islands, Lebanon, Lesotho, Libya, Micronesia, Namibia, New Caledonia, Palau, Saint Pierre and Miquelon, Sao Tome and Principe, Solomon Islands, South Sudan, Yemen.

There, T-Mobile says “you can still use calling and messaging services but data is turned off by default”. Dial #RON# to turn data on and #ROF# to turn it off. Data is then billed per use, at rates T-Mobile shows only in an interactive search, so we print none.

T-Mobile’s country search tool disagrees with the support page. It returns 256 destinations: 220 in Simple Global and 36 with no group, among them Somalia, Kiribati, Eswatini and East Timor. We follow the support page; for the 15 names outside its 21, check with T-Mobile.

Ethiopia, Namibia, South Sudan, Kiribati and East Timor are on the AT&T and Verizon lists but not on T-Mobile’s included list. Check each destination before you pick how to connect.

The cost of getting this wrong is concrete: a Beyond customer who lands in Namibia has no plan benefits and no pass to buy. Data stays off until they dial #RON#, and from then on it is billed per use. A look at T-Mobile’s country search before you leave avoids that bill.

Europe

Spain, France, Italy, Germany, Portugal, Greece, Switzerland, Turkey, Ukraine, Ireland, England, Scotland, Wales and Northern Ireland are all on T-Mobile’s included list. None of the 21 excluded names is in Europe.

The allowance is the limit, not the map: 15GB on Beyond, 5GB on More, nothing on Essentials without a pass. For the Europe country-by-country picture, see SIM cards for Europe.

Japan

Experience Beyond includes T-Satellite: texting and select apps by satellite in select countries, Japan among them (checked on October 29, 2026, T-Mobile international roaming). Other plans pay $10 a month for it. Japan itself is on the included list, so plan data and passes work there.

For a two-week trip, the 30-day pass at $75 for 30GB is the smallest pass total in our arithmetic above. The T-Mobile in Japan page goes into detail, and SIM cards for Japan covers every way to connect there.

Dominican Republic

On Essentials, a ten-day trip to the Dominican Republic fits one 10-day pass: $50 for 15GB. Our Dominican Republic plan with 5GB over 30 days is $17.99, data only (Dominican Republic eSIM). On Beyond, the same trip costs nothing extra up to 15GB.

Caribbean

Many islands are on the included list, among them the Bahamas, Jamaica, Aruba, Barbados, Bermuda, Curacao, Grenada, Haiti and Trinidad and Tobago. Cuba is on the not-included list.

Puerto Rico counts as home on T-Mobile, and T-Mobile’s page does not confirm the U.S. Virgin Islands, so check your plan before a USVI trip (see US territories below).

Costa Rica

On Essentials, a week in Costa Rica is one 10-day pass at $50 for 15GB. Beyond’s 15GB and More’s 5GB apply there as anywhere else on the list.

Philippines

A month in the Philippines fits the 30-day pass, $75 for 30GB, on a line with no data abroad. For a longer stay, remember T-Mobile’s “Not for extended international use” clause and ask T-Mobile what your line allows.

China

China, Hong Kong and Macau are three separate entries on T-Mobile’s included list, and all three take plan data and the International Pass. Mexico and Canada are on the list too, with their own allowance: see the next section.

Mexico, Canada, cruises, flights and US territories

Mexico and Canada are on the included list with their own data allowance: Experience Beyond 30GB and Experience More 15GB, then up to 256kbps. Territories split three ways, and ships and planes follow separate rules (checked on October 29, 2026, T-Mobile Mexico and Canada).

Mexico and Canada

T-Mobile’s own page differs on More. The headline groups “Experience Beyond and Experience More” at “Up to 30GB of high-speed data”. The plan list on the same page gives More “Up to 15GB”, then up to 256kbps.

We follow the plan list: Beyond 30GB, More 15GB. Check your plan.

Calls and texts between the US, Mexico and Canada come with T-Mobile’s Mexico and Canada benefit. Its page says: “Call, text, and browse in Mexico & Canada. No roaming charges.” For Essentials it names data only, at up to 128kbps, so check your plan for calls (T-Mobile Mexico and Canada).

Other plans get less: Go5G 10GB, then 128kbps; Magenta, ONE and Plus 5GB, then 128kbps; Essentials 128kbps. T-Mobile’s support page adds that hotspot use counts toward the allowance (T-Mobile: Mexico and Canada terms). The benefit is “Not for extended international use”: you must reside in the U.S., and most of your use must be in the U.S.

On a T-Mobile Prepaid line, the $5 Mexico and Canada add-on covers calls to the US, Mexico and Canada. It also gives up to 5GB of high-speed data there (T-Mobile Prepaid).

Details are on the T-Mobile Mexico and Canada page.

Cruises

At sea your phone uses the ship’s network. T-Mobile lists 533 ships where you “pay for the data, text, and voice you use”, at rates shown only in an interactive search (T-Mobile cruises). It advises keeping roaming off while the ship is docked at a U.S. port; a travel eSIM works in port, not at sea (cruise connectivity).

In flight

T-Mobile offers free in-flight Wi-Fi through airline loyalty programs on Delta, Alaska, Hawaiian and Southwest, including some international flights (T-Mobile in-flight). Texting works over Wi-Fi Calling, and no travel eSIM works in the air.

US territories

Puerto Rico is home on T-Mobile: its support page counts “the U.S. and Puerto Rico” inside its 215+. Guam and the Northern Mariana Islands (Saipan, Rota, Tinian) are on the international list, and American Samoa is not included. T-Mobile’s page does not confirm the U.S. Virgin Islands (T-Mobile country list).

We have no plan page for these places, so check your T-Mobile plan before you go.

eSIM on T-Mobile: activation, transfer and a travel eSIM next to your line

T-Mobile sells passes, not a travel eSIM; ours runs as a second line beside yours (checked on October 29, 2026, T-Mobile travel benefits). T-Mobile unlocks a postpaid phone after at least 40 days active on the line, once it is paid off (checked on October 29, 2026, T-Mobile unlock policy).

T-Mobile’s page says to turn off SIM Protection before you move your own eSIM to a new phone (T-Mobile SIM and eSIM help). Then follow the steps for your phone (how to transfer an eSIM), or use T-Life: Account → SIM transfer or activation. Menus can differ by model and software version.

On T-Mobile Prepaid, you start an eSIM at prepaid.t-mobile.com or in the T-Mobile Prepaid eSIM app, and the phone must be unlocked (T-Mobile Prepaid eSIM activation).

T-Mobile unlocks supported postpaid phones automatically and free within 2 business days of eligibility. For a Prepaid phone, the rule is 365 days since activation, or more than $100 in refills and more than 14 days since purchase. Our T-Mobile unlock guide walks through both.

Apple’s page says: “You can have two eSIMs active at the same time on supported iPhone models.” With both lines on, “your travel eSIM will be used for data”. Apple adds: “You might still incur roaming fees from your home eSIM” (checked on October 29, 2026, Apple).

So set the travel eSIM as the data line and turn off data roaming on the T-Mobile line. Then the T-Mobile line uses none of its data abroad, while its calls and texts still follow your plan (dual SIM, data roaming).

Your number stays on the main line for 2FA codes and app verification (keep your US number). Most of our plans are data only, with no number of their own; check the plan’s calls/SMS fields.

When is a travel eSIM worth it on T-Mobile?

A travel eSIM can win on T-Mobile when your line has no data abroad or its 5GB or 15GB will not last. It can also win in the 21 places left out, but not on a short trip inside your allowance (checked on October 29, 2026, T-Mobile international roaming).

On Essentials, any trip over a day is the clearest case: each 24-hour pass is $10, and a week is $50 with the 10-day pass. A data-only plan can cost less for the same days; the cost table has the sums.

On Beyond or More with heavy use, speed drops to up to 256Kbps after 15GB or 5GB. A plan with more high-speed data keeps you at full speed for longer.

In the 21 destinations T-Mobile leaves out, there is no pass at all: you pay per use or go without data. On a long stay, data on a travel eSIM does not use T-Mobile’s roaming at all.

If none of those fits you, stay on T-Mobile. For a trip that does need one, pick your destination: Europe, Japan or the Dominican Republic. Roaming or eSIM puts the carriers side by side, and all carriers is the full list.
