Dealing with SIM cards when traveling abroad can be a nightmare. Not only are they tiny, delicate pieces of hardware that are easily lost or damaged but getting your hands on a local card can sometimes prove tricky.

So tricky, in fact, that maybe you’ve just given up and chosen to pay the costly roaming charges your service provider thrusts on you.

Neither option is attractive, but there’s good news – did you know that you can get mobile data abroad without ever putting a SIM card into your phone?

Enter embedded-SIM cards, also called eSIM. They’re a new technology steadily gaining popularity among inveterate travelers, and for many good reasons.

Here are five benefits of an eSIM card that you can enjoy next time you’re abroad.

5 Benefits of an eSIM That Might Surprise You

An eSIM is a SIM card that’s built into certain newer phone models. Unlike most SIM cards, it is not removable as it is fused right into the phone’s circuitry. While such phones usually also have a slot for a removable SIM card, the eSIM functions as a secondary SIM that can provide data and coverage benefits while you’re abroad.

Here’s why that’s great.

1. You’ll Stay Connected Anywhere

According to Ericsson, about 80 percent of the world’s population has mobile phone coverage – specifically 4G. That means it’s possible to have cellphone coverage pretty much anywhere there are people.

Despite that, cell service ends at international borders for most people. That’s true even if you pick up local SIM cards wherever you go. Even then, you’ll still lack service at critical points in your trip when you’re most likely to need it.

In contrast, the biggest benefit of an eSIM is that it’s possible to get data almost anywhere in the world. (Airalo provides data plans for over 190+ countries and regions). That can even include data packs covering multiple countries, which you can purchase ahead of time while you plan the rest of your trip.

Imagine getting off that long haul flight and immediately having service. With an eSIM, you can.

2. You Won’t Lose It

Removing your domestic SIM card when you travel is a surefire way to avoid accidental roaming charges. It’s a good idea to do this unless you’ve got amazing international data coverage.

Of course, that presents its own challenges. Remember the days of brainstorming the perfect place in your luggage to store your domestic SIM card so you won’t forget where you've put it?

Remember the dizzying panic when you landed back home and realized you threw out the backup wallet where you had hidden it?

That doesn’t happen with an eSIM.

One benefit of an eSIM is that it’s stored on your device much like an app. Once you’ve downloaded it from the eSIM marketplace, it’ll hang out on your phone until you activate it. Best of all? You can store multiple eSIMs at the same time, and they’ll always be right there at your fingertips.

3. There’s No Contract Required

Believe it or not, two-year cell service contracts were once the norm. Providers loved locking people into long-term contracts, never minding that it is simply inconvenient for their customers– especially when you travel a lot.

While those are thankfully a thing of the past, it’s still common to find providers hiding favorable prices and package options behind year-long contracts. That’s annoying when you only need that international data option for a few months.

The benefit of an eSIMs from Airalo shines in its ability to offer you exactly what you need and only for as long as you need it. You can choose between three, seven, or thirty-day plan options. It’s even possible to mix and match these plans according to your travel itinerary. Likewise, if you’ve decided to stay longer in an area, topping up your eSIM with a new data plan is super easy.

(Plus, you get almost local data plan prices. Yay!)

4. It’s Secure

The eSIM is a relatively new technology, but it’s already recognized as a secure alternative to traditional SIM cards. According to GSMA, eSIM provides the same level of security as traditional SIM cards.

Some skeptics of the eSIM point to the fact that the embedded SIM makes it difficult to remove in the event of a hacker gaining access to the phone. When a phone is hacked and taken over, it’s usually done via the SIM card. With a traditional card, that control can be broken if the SIM card is removed.

(Many phone manufacturers take advantage of additional encryption to protect against this.)

However, the embedded nature of the eSIM isn’t a weakness. Since it can’t be removed easily, it reduces theft and increases the likelihood that your phone will be recovered.

5. Keep Your Existing Phone Number

We rely on our phones for so much these days, from identity verification to keeping in touch with friends. Changing phone numbers is a hassle, especially when you’re abroad.

However, with an eSIM, you can keep your phone number. This is one benefit of an eSIM  that frequent travelers love the most.

This is because an eSIM doesn’t conflict with your physical SIM card. Instead, you can switch back and forth between the two easily. You can even take calls on your domestic number while using the data available via your eSIM.

Say goodbye to updating everyone on your new phone number every six months. With an eSIM, you’ll stay connected – to the network and your friends.
