How to Avoid Roaming Charges Abroad: 7 Steps

Here is how to avoid roaming charges on a trip abroad, in one paragraph. Decide before you fly whether your US line will handle data abroad, or whether a travel eSIM or local SIM will. If your US carrier plan already includes international data, as T-Mobile's Experience plans do, use it and set nothing else up. If it does not, either accept the carrier's daily pass at $12 a day on Verizon or AT&T, or buy a travel eSIM for roughly a quarter of that over a week, turn data roaming off on your US line, and turn Wi-Fi Calling on at home so your US number still rings. The seven steps below walk through each decision, with the prices from the carriers' own pages and a cost table for a seven-day trip at the end.

Step 1: Find out what your plan already includes

Roaming charges are what a US carrier bills when your phone uses a foreign network. The first step is to see whether your plan already covers that, because on some plans the answer is yes and the rest of this guide is optional.

T-Mobile is the carrier where this is most likely. Its international roaming page says Experience Beyond, and the older Go5G Next, include "15GB of high-speed data in 215+ countries & destinations", then unlimited data at up to 256 Kbps. Its Simple Global page says Experience More, along with Go5G Plus and Magenta MAX, gets "In 215+ countries and destinations, up to 5GB high-speed data, then unlimited at up to 256 Kbps." In Canada and Mexico the allowances are larger: the same page quotes "In Canada/Mexico, up to 30GB high-speed data then unlimited at up to 256kbps." for Experience Beyond, with Experience More at 15GB. According to T-Mobile's plan page, the Essentials plans include texting in 215+ countries but no high-speed data abroad. Calls on all of these cost $0.50 a minute abroad.

Verizon's international travel page says, according to the plan descriptions there, that Unlimited Ultimate already includes international service, while Unlimited Plus and Unlimited Welcome add TravelPass automatically. That automatic add is important. It means a phone on those plans that connects to a foreign network can trigger a daily charge without you doing anything.

AT&T's international page lists no monthly international data add-on for consumers, according to the page. The only monthly item there is International Calling at $15 a month per line, which covers calls from the US and includes no data. So on AT&T the choice is the daily pass or something that is not AT&T.

Check your own plan name against these before moving on. If you are on T-Mobile Experience Beyond or Experience More, or Verizon Unlimited Ultimate, you may be done.

Step 2: Know what the daily passes cost

If your plan does not include data abroad, the carrier's fallback is a daily pass. The passes are convenient because nothing changes on the phone, but they are the most expensive way to get data on anything longer than a weekend.

Verizon TravelPass, according to Verizon's international travel page, costs $12 a day in 210+ countries and destinations and $6 a day in Canada and Mexico. You are charged only on the days you use it, and each daily session includes 5 GB of high-speed data before the speed drops to unlimited 3G. Verizon also sells an International Monthly Plan at "$100 /line per month", with 20GB of high-speed data then unlimited 3G, 250 minutes and unlimited texts in 210+ countries. Verizon recommends the monthly plan for trips of nine days or more, which matches the arithmetic: nine days of TravelPass is $108.

AT&T International Day Pass, per its page, is summed up as "Stay connected abroad on land for $12/day." in 210+ destinations, with unlimited talk, text and high-speed data on eligible plans. AT&T's support article adds "$6 for each additional line used on the same calendar day." and caps charges at 10 daily fees per line per bill period on land and in the air. On cruise ships the rate is $20 a day per line on 400+ ships, with 500MB of data per day.

T-Mobile sells International Passes for plans that need more. According to T-Mobile's plan page, the 1-day pass is $10 for 2GB, the 10-day pass is $50 for 15GB, and the 30-day pass is $75 for 30GB, each with unlimited calling, and more than 20 pay-per-use destinations are not covered.

Write down the number that applies to you. For a seven-day trip on Verizon or AT&T, the daily pass is $84 for one line, and that is the figure a travel eSIM has to beat.

Step 3: Decide which line carries data abroad

This is the core of how to avoid roaming charges. Roaming is billed per line that uses a foreign network, so the trick is to make sure the only line using data abroad is one you have deliberately paid for at a price you accept.

You have three choices for that line. Keep data on your US line and pay the pass, or use the included allowance if you have one. Add a travel eSIM for the destination and put data on it, keeping the US line for calls and texts. Or put a local physical SIM in the tray, which on a single-slot phone takes your US line offline for the trip.

The eSIM route needs a supported, unlocked phone. Apple's eSIM page says "An iPhone XS, iPhone XS Max, iPhone XR, or later" supports eSIM, Google's Pixel page says "Pixel 4 and later: All phones work with eSIM.", and Samsung's US page lists the Galaxy S20 through S26 series, Note20 and the recent Fold and Flip models as hybrid eSIM devices. Our guide on whether your phone supports eSIM has the full model lists and the carrier-lock check. If the phone is locked, Apple notes that "Only your current carrier can unlock your iPhone.", and Google says carrier-bought Pixels may stay locked for up to two years.

Step 4: Turn off data roaming on the US line

Once a travel eSIM is the data line, the US line should not be allowed to use foreign data at all. Every modern phone has a data roaming switch per line, and the travel setup is to leave it off for the US line and on for the travel line.

We are deliberately not quoting a settings path here, because the carrier and manufacturer pages we rely on for this guide do not give one, and the exact menu wording changes across phone models and software versions. The general shape is the same everywhere: the cellular or mobile network settings list each line, each line has a toggle for roaming, and there is a separate choice for which line is the default for mobile data. Set the data default to the travel line and the roaming toggle on the US line to off.

Airplane mode is the blunter tool. It cuts every radio, so it stops roaming completely, but it also stops the travel eSIM and your calls. It is useful for the moment you land, before the lines are configured, and for flights, not as a way to spend the trip.

The reason this step matters even on a pass plan is the automatic add. Verizon says Unlimited Plus and Unlimited Welcome add TravelPass automatically, which means a line that merely connects abroad can start a $12 day. If you have an eSIM carrying data, there is no reason to let that happen.

Step 5: Turn on Wi-Fi Calling before you leave

Wi-Fi Calling is how your US number keeps working on a trip without roaming, and the carriers' rules on it are specific enough to quote.

Verizon's Wi-Fi Calling FAQ says "Calling back to the US is free." over Wi-Fi while abroad, while calls to other countries bill at international long-distance rates. The same FAQ has a line every Verizon iPhone user needs: "Wi-Fi Calling can't be activated after you leave the country." Switch it on while you are still in the US.

AT&T's Wi-Fi Calling article says "You can call U.S. numbers with no additional charge." from abroad. Calls to non-US numbers, including numbers in the country you are visiting, bill as international long distance.

T-Mobile's Simple Global page says "Calls, including over Wi-Fi, are $0.50/min. in 215+ countries and destinations.", while Wi-Fi calls to the US, Mexico and Canada are free.

The practical setup is to leave the US line installed and on, with data roaming off, and let it fall back to Wi-Fi Calling whenever the phone is on hotel or café Wi-Fi. Calls and texts to your US number then reach you at no roaming cost, and two-factor codes keep arriving.

Step 6: Buy a travel eSIM sized for the trip

The eSIM is the alternative that turns an $84 week into a $25 week, and the prices in our eSIM directory show the range. These are the plan prices we recorded on the provider pages on the check date shown in the directory, and they change, so treat them as a snapshot.

For Japan, Nomad lists an Unlimited 7-day plan at $25.00 on its Japan eSIM page, Airalo lists Unlimited 7 days at $26.50 on its Japan page, and Saily lists 5 GB for 30 days at $10.99 on its Japan page. For Italy, Airalo lists Unlimited 7 days at $23.00 on its Italy page, Holafly lists Unlimited 7 days at $23.90 on its Italy page, and Saily lists 1 GB for 7 days at $3.99 on its Italy page.

Which size you need depends on habits. Our trip data calculator uses published per-hour figures: Google Maps navigation at 5 to 10 MB an hour from a Consumer Cellular blog figure, social scrolling at 120 MB an hour without video and up to 700 MB with video from the same source, HD video at 2,500 MB an hour from AT&T's data calculator, and the Netflix mobile app's Automatic setting at about 250 MB an hour from Netflix Help. A week of maps, messaging and photo-heavy social media fits in a few gigabytes. A week with an hour of HD video a night does not, and that is when the unlimited 7-day plans at $23 to $27 are the better buy.

Install the eSIM on home Wi-Fi, label it, and set it as the data line before you go. Our eSIM vs physical SIM guide covers the setup paths by phone.

Step 7: Cut the data you use at all

The cheapest gigabyte is one you never download. Two preparations shrink the plan you need, whichever option you chose.

Download offline maps. Google Maps Help says "your offline maps can guide you to your destination as long as the entire route is within the offline map." The limits are real: "When you're offline, transit, bicycling, or walking directions are unavailable.", there is no traffic or alternate routes, the maps expire and must be updated, and "You can't download offline maps in some countries or regions". On Android, search a place, then More > Download offline map > Download, or go to Profile > Offline maps > Select your own map.

Use the hotspot rather than two plans. If two people travel together, one eSIM can serve both phones. T-Mobile's hotspot page describes it as "Mobile Hotspot lets you share the high-speed data of your phone, tablet, or Wi-Fi Hotspot" with up to 10 devices, with the caveat that "Price and high-speed Mobile Hotspot data allotment varies depending on your plan." Whether a travel eSIM allows hotspotting is a per-plan question to check on the provider's page.

Set streaming apps to their data-saver modes before you leave. The Netflix figures above show why: the mobile app's Save Data setting is about 167 MB an hour against 3,000 MB an hour or more on Maximum Data, per Netflix Help.

Seven-day trip cost, option by option

Here is the arithmetic for one line on a seven-day trip, using only the figures cited above. Multiply or divide as your trip length changes.

Option	Seven-day cost	Data included	Source
Verizon TravelPass, most countries	$84 (7 x $12)	5 GB high speed per day, then 3G	Verizon international travel page
Verizon TravelPass, Canada or Mexico	$42 (7 x $6)	5 GB high speed per day, then 3G	Verizon international travel page
Verizon International Monthly Plan	$100	20GB high speed, then 3G	Verizon monthly plan page
AT&T International Day Pass, one line	$84 (7 x $12)	Unlimited high speed on eligible plans	AT&T International Day Pass page
AT&T International Day Pass, second line	$42 (7 x $6)	Same	AT&T support article
T-Mobile Experience Beyond	$0, included	15GB high speed, then 256 Kbps	T-Mobile roaming page
T-Mobile Experience More	$0, included	Up to 5GB high speed, then 256 Kbps	T-Mobile Simple Global page
T-Mobile 1-day International Pass, daily	$70 (7 x $10)	2GB per pass	T-Mobile roaming page
T-Mobile 10-day International Pass	$50	15GB	T-Mobile roaming page
Nomad Japan Unlimited 7 days	$25.00	Unlimited	Nomad Japan page
Airalo Italy Unlimited 7 days	$23.00	Unlimited	Airalo Italy page
Saily Japan 5 GB / 30 days	$10.99	5 GB	Saily Japan page
Saily Italy 1 GB / 7 days	$3.99	1 GB	Saily Italy page

Three things stand out. If you are on T-Mobile Experience Beyond or Experience More, your allowance is already paid for and the eSIM only makes sense if you expect to burn through 15GB or 5GB. On Verizon or AT&T, a week on the daily pass costs more than three times a seven-day unlimited eSIM for Italy or Japan. And for a light user, a few dollars of eSIM data covers maps and messaging for the whole week.

The checklist to run the week before you fly

Check your plan name against the T-Mobile and Verizon inclusions in Step 1. Note the daily pass price that applies to you from Step 2. Confirm the phone supports eSIM and is unlocked, using the lists linked in Step 3. Buy and install the eSIM on home Wi-Fi, sized with the calculator. Set the travel line as the data line and switch data roaming off on the US line. Turn on Wi-Fi Calling while you are still in the US, which is mandatory on Verizon iPhones. Download offline maps for the cities and routes you will drive. Set streaming apps to data saver.

Do those and the bill when you get home is the eSIM price and nothing else. That is how to avoid roaming charges: not by going dark, but by choosing in advance which line is allowed to spend money abroad.
