Long gone are the days where we had to flip through the pages of a map or send a postcard to stay in touch with our friends and family. Along came the internet and thankfully, nowadays these tasks have been simplified for us, making travel overseas so much easier. Whether you’re a digital nomad like us, a frequent business traveler or you just love exploring the world (also like us), the question of whether an eSIM or a physical SIM card is better for your travels is a question that keeps popping up. 

With the rise of eSIM technology, travelers finally have more options than ever when it comes to choosing how they get online and stay connected anywhere they go. Here’s a full breakdown of eSIM vs physical SIM to help you make the best choice for your next trip.

What is an eSIM?

An eSIM (Embedded Subscriber Identity Module if you want to get technical) is a digital SIM that allows you to activate a cellular plan from a carrier without the need for a physical SIM card. The beauty of an eSIM lies in the ability to switch carriers or plans without having to swap out a physical card. Apps like AloSIM and Airalo can make this extremely simple. This feature is particularly handy for travelers who move between countries or need to change their mobile data plan frequently. For additional information on what an eSIM is, check out our guide to What is an eSIM?

eSIM pros and cons

eSIM for travelers: The pros

• No physical swapping required: No need to carry a SIM ejector tool or worry about losing tiny SIM cards, your eSIM is always in your device, ready to go.

• Convenience: With an eSIM, you can easily switch between carriers and plans digitally. No more juggling multiple SIM cards.

• Great Value: eSIMs from providers such as Nomad, Airalo, Holafly and others offer you very reasonable prices on plans overseas, likely saving you from expensive roaming fees.

eSIM for travelers: The cons

• Compatibility issues: Not all smartphones or devices support eSIM technology. If your device isn’t eSIM-compatible, you won’t be able to use services like Airalo. If you have a newer phone, it’s quite likely that your phone will be compatible as the technology has become so much more common.

• Setup process: Although setting up an eSIM is generally quite simple, even more so if you check our guide here, some users may find the process complex, especially if they are not tech-savvy. Physical SIM cards can be fiddly and require an ejector tool (where did I put that again?) but you simply need to replace one card with another, setting up an eSIM requires the following of a number of steps on your device. This process might be intimidating or confusing for some users.

For the full breakdown of advantages and disadvantages, see our eSIM Pros and Cons guide.

What is a physical SIM card?

On the other hand, a physical SIM card is the traditional way of accessing mobile networks. It’s a small, removable chip that stores your carrier’s data and needs to be manually inserted into your device, usually with a SIM ejector tool. While it may seem outdated, physical SIM cards are still widely used and supported worldwide.

Physical SIM card pros and cons

Physical SIM card for travelers: The pros

• Universal compatibility: Almost every mobile device can accommodate a physical SIM card, making it a safe bet for travelers using older phones or certain models that don’t support eSIM. Want to know if your phone supports eSIM? Check out our guide here.

• Potentially cheap: If you can navigate the process perfectly, there’s a chance that you can get a good local plan.

Physical SIM card for travelers: The cons

• SIM swapping: This can be highly frustrating, especially with SIMs being so tiny these days. You’ve also probably only got 1 SIM slot, meaning that if you have 2 numbers, you’re going to be swapping a lot!

• Easy to lose: Physical SIM cards can be lost quite easily, we’ve been there.

• The local SIM card purchase: Purchasing a physical SIM card after arriving in a new country often means hunting for a store, providing your details, activating the SIM and more, it can be pretty painful. You’re navigating unfamiliar places, possibly dealing with language barriers, all without internet connectivity. eSIMs spare you this whole process.

• Extortionate costs: If you’re trying to roam using your home mobile plan, there’s a high likelihood prices will be through the roof.

Choosing what’s best for you: eSIM vs physical SIM card

Ultimately, the choice between using an eSIM or a physical SIM card boils down to personal preference, travel habits and technological compatibility. Here are a few final considerations to guide you:

1. Device compatibility: Ensure your device supports eSIM technology, is unlocked and ideally is dual SIM compatible if opting for a travel eSIM. For physical SIMs, also check that your device is unlocked and compatible with local network bands.

2. Travel type: Consider how long you’ll stay and if you’ll change immigration status in the country. Shorter, less permanent trips would be more suitable for travel eSIMs, longer stays might be better suited to finding a local SIM plan. 

3. Cost comparison: Compare requirements and costs between using a travel eSIM, roaming with your home country’s SIM, and buying a local SIM, including data rates and potential roaming fees.

4. Roaming charges: Be aware of the roaming charges associated with using your home country’s SIM abroad to avoid unexpected expenses. Costs can add up!

5. Convenience and availability: Consider the convenience of activating a travel eSIM digitally, versus the potential hassle of finding and purchasing a local SIM upon arrival.

6. Flexibility and scalability: For those visiting multiple countries or wanting different types of plans, a travel eSIM can offer the flexibility to easily switch plans and providers as you move around, whereas local SIMs are tied to one country’s network and rates.

7. Customer support: Bear in mind that you can receive support in English from the travel eSIM apps, but may not be able to get the same from a local SIM provider. This can prove difficult when canceling, changing plans, topping up etc.

Our opinion: eSIMs offer significant advantages for travel

You probably wouldn’t be surprised to know that we love and regularly use eSIMs for travel. For us, it’s really hard to beat the experience of buying your eSIM online and in advance without any headaches around registration and being able to get online almost instantly. We’ve spent significant amounts of time in different countries and originally, we did try local SIM cards but it just proved difficult on many levels.

Just to give you an example, in one of our home bases Colombia, we’ve had to queue for an hour just to purchase a local SIM card. We were constantly bombarded with SMS adverts, and our mobile service stopped working after only a couple of weeks! This meant another long line for technical support. Fortunately we speak Spanish or that would have been a nightmare.

Another example is when we moved to the UAE and weren’t able to get a local SIM or a tourist SIM card for a period of time because of issues with our ID verification. Needless to say, a travel eSIM saved us in that instance. 

Our choice: eSIM!

Final thoughts: Which is better for travel?

In comparing eSIM vs physical SIM card, it’s clear that each has its unique strengths, tailored to different needs and lifestyles. Choosing between them isn’t just about picking the latest tech, it’s really about what works best for you.

eSIMs shine for those who love convenience and travel often. They let you switch carriers easily, perfect for people like us looking to avoid roaming charges.

Physical SIM cards, on the other hand, keep things simple and straightforward. They’re universally compatible, making them a go-to for people who prefer the reliability and tangible control of a physical card. They’re especially handy for those who might not have eSIM-compatible devices yet.

Although we prefer eSIMs for travel, in the end, the choice between an eSIM or physical SIM card ultimately depends on your travel habits, device compatibility and personal preferences. Both options offer ways to stay connected, each adapting to different aspects of our lives.

Remember, you can also have the best of both worlds, a physical SIM and an eSIM on a dual SIM phone. This is our current use case as we keep our home plan on a physical SIM card and travel on eSIMs to take advantage of cheaper data plans.
