What Is an eSIM?

Lost without service? Here’s an explanation of what eSIMs are — and how they’re changing the game for travelers. 

Your bags are packed, your itinerary is set, and you’re ready to explore. But the moment you step off the plane, your phone flashes a dreaded message: No Service.

You scramble to connect to airport WiFi (if it’s even available), fumble with a local SIM card you bought at a kiosk, and pray you remember your hotel’s address before getting into a taxi. Meanwhile, your friends and family have no idea where you are. Sound familiar?

“ESIMs eliminate roaming charges, simplify setup, and ensure you’re never stranded without service.

Because the only thing you should be worrying about on your trip is where to explore next.”

For years, travelers have been caught in this all-too-common nightmare — disconnected, disoriented and sometimes downright lost. But thanks to eSIM technology, staying connected abroad is no longer a hassle.

What Is an eSIM?

An eSIM (embedded SIM) is a digital SIM card built directly into your phone. Unlike traditional SIM cards, eSIMs don’t require swapping out tiny plastic chips. Instead, you can activate a data plan by scanning a QR code — no waiting, no extra hardware.

And eSIMs are quickly becoming the standard. The number of eSIM-enabled devices is expected to grow from 1.2 billion in 2021 to 3.4 billion by 2025, according to a study by Juniper Research. That’s a 180% increase.

How Do eSIMs Work?

Setting up an eSIM is incredibly simple:

1. Make sure your phone is compatible. 

2. Purchase an eSIM plan from a provider online.

3. Receive a QR code via email.

4. Scan the code with your phone’s camera.

5. Boom — you’re connected!

With an eSIM, you can store multiple data plans on a single device, meaning you can switch between providers with just a few taps. Many travelers keep their home number active while using an eSIM for data abroad — no more expensive roaming fees.

Why Travelers Are Ditching Traditional SIMs for eSIMs

1. Instant Connectivity

Gone see those frantic airport searches for a SIM card vendor. You can activate your eSIM before you even take off.

2. No More Roaming Nightmares

International roaming fees can be brutal. A 2023 study by WhistleOut found that some U.S. carriers charge up to $10 per day for international data, while pay-as-you-go rates can skyrocket to $2.05 per MB (that’s $2,050 for 1 GB!). ESIMs offer flat-rate, prepaid data plans that can save travelers hundreds of dollars per trip.

3. Eco-Friendly and Hassle-Free

ESIMs eliminate the need for plastic SIM cards, packaging and shipping, making them a greener choice. Plus, no more losing or damaging those tiny chips.

4. Dual SIM Capability

Need to keep your regular number active for calls and texts? No problem. Many eSIM-compatible phones let you use your primary number for calls while using an eSIM for data abroad.

5. Hotspot and Data Sharing

Some eSIM plans even allow tethering, so you can share your data with a laptop or travel companion — perfect for digital nomads or group travelers.

What to Know Before Using an eSIM

While eSIMs are a game-changer, they aren’t perfect for everyone. Here are a few things to keep in mind before making the switch:

1. Your phone must be compatible. 

Not all phones support eSIMs. As of now, only newer models from Apple, Samsung, Google and a few other brands work with eSIMs. If you’re unsure, check your phone’s settings or the provider’s compatibility list before purchasing.

2. You need WiFi for setup.  

To install an eSIM, you must be connected to WiFi. This means you should set it up before leaving home or from a hotel with stable internet. Forget to do it? You might struggle to get online when you land.

3. You don’t get a phone number on data-only plans. 

Most travel eSIMs are data-only, meaning they don’t provide a phone number for calls or texts. If you need to make calls, you’ll have to use WhatsApp, FaceTime or Google Voice instead.

4. Data sharing isn’t available everywhere. 

Not all eSIM plans allow hotspot sharing. If you plan to connect your laptop or share data with a travel partner, check whether your plan supports it — especially if you’re traveling in a remote area.

5. Coverage can vary. 

ESIMs rely on local networks, meaning signal strength and speeds depend on where you are. If you’re in a rural or mountainous area, you might experience weaker coverage — just like with a regular SIM card.

6. Switching providers may take a few steps. 

While eSIMs make it easier to change carriers, some phones require a manual reset when switching networks. If you’re juggling multiple providers, this could cause minor delays.

FAQs About eSIMs for Travelers

What exactly is an eSIM?

If you have a newer phone (like an iPhone XR or later, Google Pixel 3 or later, or a recent Samsung Galaxy model), the eSIM technology is already built into your device. You don’t need any extra hardware — just activate an eSIM plan by scanning a QR code or entering details manually, and your phone connects to a local network.

Since it’s embedded in your device, an eSIM can’t be lost, stolen or damaged like a traditional SIM card.

Why would I need an eSIM?

If you travel internationally, an eSIM lets you stay connected without expensive roaming fees or the hassle of swapping physical SIM cards. With an eSIM, you can activate a local or global data plan before your trip and have internet access the moment you land.

Does an eSIM replace an international data plan?

An eSIM is an international data plan, but instead of using your home carrier’s potentially expensive roaming package, it connects to local networks at a better rate. Unlike traditional international data plans that require carrier contracts, eSIMs are prepaid and flexible.

Can I use an eSIM and my regular SIM at the same time?

Yes. Most eSIM-compatible phones have dual SIM functionality, meaning you can keep your regular SIM active for calls and texts while using an eSIM for data. This is great for people who need to receive calls on their primary number while using a local data plan abroad.

Do eSIMs work in every country?

ESIM providers offer coverage in most major travel destinations, but coverage quality varies depending on local networks. Always check if your destination supports eSIMs before purchasing a plan.

What happens if I lose my phone while using an eSIM?

If you lose your phone, your eSIM is tied to that device and cannot be removed or swapped like a physical SIM card. However, you can still access your account from another device to transfer your eSIM, depending on your provider’s policy.

Can I share my eSIM data with other devices?

Some eSIMs allow hotspot sharing, while others restrict tethering. If you plan to use your phone’s hotspot for a laptop or another device, make sure your eSIM provider supports this feature in your destination.

Are eSIMs secure?

Yup. ESIMs cannot be physically stolen or removed, making them more secure than traditional SIM cards. However, like any digital service, it’s important to use strong passwords and enable remote tracking features on your phone in case of loss or theft.

How do I switch back to my regular SIM after my trip?

It’s easy! Simply go into your phone’s SIM settings and switch back to your primary SIM. If you don’t plan to use your eSIM again, you can delete it from your device.

Travel Planning Made Easy With Chatbots

If you want a stress-free travel experience, let chatbots help you find deals, book flights and hotels and create custom itineraries. Plus: Learn why you should have a VPN, too. 

Travel planning has gotten a whole lot easier thanks to chatbots.

In the past, planning a trip was a time-consuming and often frustrating experience. Even today, many travelers have to spend hours researching flights, hotels and activities that fit within their interests, budgets and dates. 

But now there’s a new way to plan travel: chatbots. Generative AI chatbots are programs that simulate human conversation, using natural language processing and machine learning, allowing users to complete a variety of travel-related tasks with a digital device — almost as if they were communicating with a person.

“Today’s chatbots are not like HAL, the sentient AI in Stanley Kubrick’s ‘2001: A Space Odyssey.’

They’re simply tools that can help you make your travel planning easier.”

Even if you’re a seasoned pro, chatbots can still help you plan your next trip. New tech tools are making travel planning easier than ever. According to research by Humley, a UK-based tech company that creates AI-assisted chatbots, 87% of people surveyed said they would use a travel chatbot if it could save them time and money.

Today’s chatbots are not like HAL, the sentient AI in Stanley Kubrick’s 2001: A Space Odyssey. They’re simply tools that can help you make your travel planning easier.

A travel chatbot can act as a personal assistant, offer budget-friendly travel options, book transportation and offer suggestions based on user behavior. If you have an issue, it can seem as if airlines make you wait on hold for longer than the flights you’re trying to book. Why wait on hold for an hour when you can speak with a smart computer immediately? Hop aboard this growing trend.

Where to next? Chatbots can help you decide — and get the best deals.

Benefits of Travel Chatbots

As chatbots become more nuanced and sophisticated, they offer a wider range of benefits for both travelers and travel businesses. Plus they’re able to learn and adapt to your personal needs. Here are the most common ways bots are revolutionizing the travel industry:

Up-to-date information: One of the biggest benefits of travel chatbots is that they can provide travelers with up-to-date information on prices, destinations and packages. This information is constantly being updated, so travelers can be sure they’re getting the best possible deal.

Multilingual support: Chatbots can be programmed to speak multiple languages, which makes them accessible to a global audience.

Personalized recommendations: Travel chatbots can also provide personalized recommendations to travelers. This is done by taking into account the traveler’s interests, budget and travel history. This can help travelers to find the perfect experience for them.

Real-time response: Forget limited office hours and automated voice prompts. Chatbots are available 24/7, so you can get help with your travel plans no matter what time of day it is. They’re also versatile enough that they can pass the baton to a human agent if things get tricky. With almost half of all customers expecting round-the-clock availability, real-time answers are the name of the game. 

Increased efficiency: Chatbots can help travel businesses increase their efficiency by handling a large number of customer inquiries without the need for human intervention. This can free up staff members to focus on other tasks, such as providing more personalized service to customers.

Kick back and relax, and let AI do the heavy lifting.

How Chatbots and Other Tools Can Make Travel Planning Easier

They make initial inquiries a breeze.

Navigating travel plans can be as chaotic as a tourist rush at the Louvre. Ever-changing rules and questions about travel insurance, restrictions and fees, can leave your head spinning. But fear not: These trusty sidekicks can answer your questions quickly and reliably, without the long wait for a live agent. 

They track lost luggage.

When your luggage goes missing in a labyrinth of unfamiliar airports, fear not, weary traveler, for the chatbot is here to lend a helping hand (or virtual voice). Armed with real-time data from airports and other points of departure, they can offer immediate assistance to track it down. And should misfortune strike and your baggage goes entirely AWOL, a chatbot can guide you through the bureaucracy of filing a claim. 

If you’re planning a trip to Vietnam, a chatbot might suggest an excursion on Ha Long Bay — and score you a good deal.

They make suggestions you might actually find useful. 

Chatbots can collect data about customer preferences and behavior, which can be used to improve the travel experience for future customers. And armed with some of your personal preferences, these digital dynamos can get quite adept at weaving their magic to create your ultimate travel package, seamlessly bundling flights, hotel stays, car rentals, and even sweet discounts on tours and activities. 

Think of chatbots as concierges with insider knowledge, coming up with hidden gems you might have otherwise missed. 

They can find the most favorable conditions for booking. 

Chatbots like Expedia’s on Facebook Messenger, can be the ultimate deal-finder. Just type in your desired destination and travel dates, and even throw in specific requests like non-smoking rooms or all-inclusive resorts — and the chatbot will swiftly sift through a variety of options, presenting you with a curated selection of relevant options. 

They can also simplify arranging wheelchair services, changing check-in dates and selecting the best seats. With a few taps and clicks, you can effortlessly finalize your reservations, make payments and voilà! Your detailed itinerary will be whisked to your phone’s text app or email inbox.

They help reduce the frustration of the cancellation process. 

Nobody likes dealing with cancellations, but with chatbots, the process has never been easier. They’re equipped to easily access customer info, retrieve reservation codes and navigate refund policies. 

Bonus tip! Set up a VPN for deals, privacy and access to foreign streaming platforms. 

A VPN (virtual private network) can act as a cloak of invisibility, a gateway to unbeatable deals and a VIP pass to entertainment options. It encrypts your data, masks your location and routes your online usage securely. 

What does that mean for travelers? First, access those sweet local deals! Connect to a server in your desired region and unveil a treasure trove of unbeatable prices. Second, you can indulge in global entertainment — log onto Netflix UK, for example, no matter where you are. 

Here’s how to set up a VPN:

1. Find a reputable VPN provider with the right features.

2. Download and install their app.

3. Sign up, configure and select your desired server location.

4. Connect with a single click, and you’re off to the races.

5. Confirm your new virtual location by checking your IP address on a dedicated website.

From getting the best prices to tracking lost luggage, chatbots can make the process more seamless. Best of all, they’re available at all hours — and won’t put you on hold for half an hour.

Travel Help — No Humans Needed

Need to arrange wheelchair services? Find the best deals? Score a sweet excursion package? With chatbots and AI, you’ll save time and effort — and, chances are, have a more pleasant experience than you would being on hold for interminable amounts of time and getting shuffled around from one department to another. And they’re getting better at an exponential rate.

Don’t be afraid to embrace the power of chatbots, because the tech travel journey has just begun! –Tony Olsen
