How to Avoid Roaming Fees While Travelling: eSIM Cards and International Data Plans

The easiest way to avoid roaming fees while traveling internationally is to use an eSIM, a digital SIM card you activate on your phone before you leave home, giving you local data rates in your destination country without swapping any physical cards. Providers like Airalo, Holafly, and Nomad sell plans starting around $4 to $5 for basic coverage, and setup takes about five minutes.

I used to land in a new country and immediately start hunting for a SIM card kiosk at the airport. Sometimes the line was long. Sometimes the vendor only took cash. Sometimes my phone needed a nano-SIM but the kiosk only had micro-SIMs. The whole process was a small headache that kicked off every international trip. eSIMs eliminated all of that for me, and they will probably do the same for you.

What Is an eSIM and How Does It Work?

An eSIM is a programmable SIM chip already built into your phone. Instead of popping in a physical card, you scan a QR code or download a profile through an app, and your phone connects to a local carrier in your destination country. You keep your regular phone number on your primary SIM for calls and texts, while the eSIM handles data like maps, messaging apps, ride-hailing, and everything that needs internet.

The technology has been around since 2017, but it really hit its stride in the last few years as more phones added support and more providers entered the market. Today, eSIMs cover well over 200 countries and territories, and the providers competing for your business have driven prices down significantly.

Which Phones Support eSIM?

Before you get excited about eSIMs, you need to confirm your phone supports them. The good news is that most phones sold in the last four to five years do.

• iPhone: iPhone XR, XS, and every model released after 2018 support eSIM. The iPhone 14 and later models sold in the US are eSIM-only with no physical SIM tray at all. Note that iPhones purchased in mainland China generally do not support eSIM.
• Samsung: Galaxy S20 and newer, all Z Flip and Z Fold models, the Note 20 series, and select A-series phones like the A54 and A55 support eSIM.
• Google Pixel: Pixel 3 and every model released after it support eSIM. Google was actually one of the earliest adopters, introducing eSIM with the Pixel 2 back in 2017.

One critical detail: your phone must be carrier-unlocked to use a third-party eSIM. If you bought your phone through a carrier on an installment plan and have not paid it off, it may still be locked. Check with your carrier before your trip, since unlocking usually takes a phone call or an online request.

The Big Three eSIM Providers Compared

There are dozens of eSIM providers now, but three dominate the traveler market: Airalo, Holafly, and Nomad. Each takes a slightly different approach to pricing and coverage.

Airalo

Airalo is the largest eSIM marketplace and the one I have used the most. They sell fixed-data plans where you choose how many gigabytes you want and how many days of validity. A basic 1 GB, 7-day plan for a single country runs between $4.50 and $6.00 depending on the destination. Larger plans go up to 20 GB with validity periods stretching to a full year. Airalo also offers regional plans covering multiple countries (handy for a multi-stop Europe trip) and global plans covering nearly every destination. Their coverage breadth is hard to beat.

Holafly

Holafly takes a different approach: unlimited data. Every plan gives you unlimited data for a set number of days, from 1 to 90 days. This is appealing if you are a heavy data user or just do not want to think about rationing gigabytes. They also offer monthly subscriptions ranging from about $40 to $65 per month. Holafly is the only major provider that includes 5G on every plan, which matters if you are in a city with strong 5G coverage. Their coverage in the Middle East and Oceania tends to be strong.

Nomad

Nomad offers some of the lowest entry prices in the market. You can find 1 GB plans for as little as $1.30 in parts of Asia and the Americas. Like Airalo, Nomad uses fixed-data plans. Their Asian coverage is particularly strong, which makes them a good pick if you are traveling through Southeast Asia or East Asia. The trade-off is that their overall country coverage is slightly smaller than Airalo's for most regions.

eSIM vs. Traditional Roaming: The Cost Comparison

Here is where eSIMs really shine. Major US carriers charge between $6 and $12 per day for international roaming passes. A two-week trip to Europe on AT&T's International Day Pass would cost $140 at $10 per day. The same trip with an Airalo regional Europe eSIM (say, 5 GB for 30 days) costs around $18 to $25. Even Holafly's unlimited 15-day plan runs roughly $47. Either way, you are saving $90 to $120 compared to carrier roaming.

And that is assuming you even use the roaming pass correctly. Plenty of travelers have horror stories about accidentally disabling their roaming pass, letting it expire mid-trip, or getting charged for data in a country not covered by the pass. With an eSIM, your regular carrier data stays off. There is no accidental roaming bill waiting for you at home.

How to Set Up an eSIM Before Your Trip

The best time to set up your eSIM is the day before you travel, while you are still on your home Wi-Fi. Here is the process:

• Step 1: Download the provider's app (Airalo, Holafly, or Nomad) and create an account.
• Step 2: Search for your destination country or region and pick a plan that fits your trip length and data needs.
• Step 3: Purchase the plan. You will receive a QR code or a direct installation prompt.
• Step 4: Go to your phone's Settings, find the eSIM or Cellular section, and add the new plan. On iPhone, this is Settings, then Cellular, then Add eSIM. On Android, it varies slightly by manufacturer but lives in the SIM or Network settings.
• Step 5: Label the new line something like "Travel Data" so you can easily toggle it on and off.
• Step 6: Keep the eSIM turned off until you land. When you arrive, turn off data roaming on your primary line, turn on the eSIM line, and you are connected.

The whole process takes five minutes at most. Some providers even let you install the eSIM but delay activation until you arrive, so the validity period starts when you actually need it rather than when you install it.

Which Provider Should You Pick?

It depends on how you travel:

• Budget-conscious and light data user: Airalo or Nomad. You can buy exactly the amount of data you need and keep costs under $10 for a short trip.
• Heavy data user or streaming on the go: Holafly. The unlimited plans mean you never have to worry about hitting a cap, and the included 5G is a nice bonus in supported areas.
• Multi-country trip: Airalo's regional plans cover the most countries. A single Europe plan works across 30+ countries without switching eSIMs at each border.
• Asia-focused travel: Nomad offers excellent Asian coverage at very low prices. If your trip hits Thailand, Vietnam, Japan, or South Korea, check Nomad first.

Tips from Someone Who Has Used eSIMs on 20+ Trips

A few things I have learned the hard way:

• Screenshot your QR code. If something goes wrong with the installation, you may need it again. Store it in your photos or email it to yourself.
• Check if calls are included. Most travel eSIMs are data-only. You will not be able to make traditional phone calls or send SMS through the eSIM line. Use WhatsApp, FaceTime, or similar apps for calls instead.
• Turn off your primary line's data roaming. This is the most important step. If your primary carrier's data roaming stays on, your phone might use it instead of the eSIM, and you will get a roaming bill anyway.
• Buy slightly more data than you think you need. Running out of data in a foreign country is stressful. An extra gigabyte or two costs very little and gives you a cushion.
• Airport lounge Wi-Fi is your backup. If your eSIM has issues after landing, head to an airport lounge where you can use the Wi-Fi to troubleshoot. Lounges accessible via Priority Pass or your travel credit card are perfect for this.

What About Physical SIM Cards?

Physical SIM cards still work fine, and in some countries they are cheaper than eSIMs. In places like Thailand, India, and parts of Southeast Asia, you can buy a local SIM at the airport for very little money. The downside is the time spent at the kiosk, the potential language barrier, and the need to carry a SIM removal tool. For most travelers, the convenience of an eSIM outweighs the small potential savings of a physical card.

If your phone does not support eSIM, a physical SIM is still your best option for avoiding roaming fees. Buy one at your destination airport or order one online before your trip from providers like SimsDirect or Amazon.

The Bottom Line

Roaming fees are a solved problem. eSIMs give you affordable, reliable data in almost every country, and they take less time to set up than it takes to order a coffee. Pick a provider, install the profile before you leave, and land ready to navigate, translate, and message without worrying about a surprise bill. It is one of those travel upgrades where the only regret is not doing it sooner.

And when you do land, having data immediately means you can check lounge locations, pull up your card benefits, and find your way around the airport without hunting for Wi-Fi. That alone makes the five-minute setup worth it.
