Pros and Cons of using an eSim for International Travel

In the United States, I have a cell phone provider for domestic calls, texts, and data. However, when I travel internationally, my current phone provider’s international plan is not cost effective at $10 per day for data only with additional costs for phone calls and sms text messaging. So I am always looking at ways to stay connected during my travels while also saving money.

For my last couple of international trips, I used an eSim card from a couple of different companies to access data on my phone while abroad. This allowed me to use apps, such as Google Maps, WhatsApp, FaceTime, and other social media apps to stay connected to my friends and family while turning my current cell phone line off so that I did not use any data with my primary plan.

What is an eSim?

An eSIM, or embedded SIM, is a digital SIM card that is built directly into a device rather than using a removable physical card. It stands for "embedded Subscriber Identity Module" and serves the same purpose as a traditional SIM card: it authenticates your device on a mobile network and enables you to make calls, send texts, and use mobile data.

Here’s how it works:

1. Digital Activation: Instead of inserting a physical SIM card, you activate an eSIM by downloading a carrier profile or plan directly to your device. This process often involves scanning a QR code or entering activation details provided by your carrier.

2. Multiple Profiles: Many devices with eSIMs allow you to store multiple carrier profiles, so you can switch between different carriers or plans without swapping SIM cards. This is particularly useful for travelers who want to use local carriers in different countries.

3. Space-saving: Because eSIMs are embedded, they save physical space in a device. You do not need to worry about storing your primary sim card while using this sim.

4. Security and Convenience: eSIMs can offer enhanced security and convenience features. For example, they can be remotely programmed or updated, reducing the need for physical card replacements if you change carriers or plans.

Devices that commonly use eSIM technology include newer smartphones, tablets, and smartwatches. Many major carriers worldwide support eSIMs, but availability can vary depending on your region and device.

Ludwigsburg, Germany

In Germany, I used the French company, Orange Travel. Since I was planning on traveling to multiple countries and solo for some of the duration of my trip, I wanted the ability to make local calls. Orange had plans that included both data and phone calls with a local French phone number.

Douro Valley, Portugal

In Portugal, I used Airalo for a data only plan. They have local, regional, and global eSims. Since the only country I was visiting for this trip was Portugal, I chose the local Portugal eSim to be able to connect to the local networks. (save $3 off your first purchase using code: KATIE9634)

Setting up an eSim

Setup for both eSims was very similar. At the time that I purchased Orange, their setup required you to scan a QR code to start the activation process, whereas Airalo allowed you to purchase the plan and start the activation process through their app.

I setup my Orange eSim while at home before I left for my trip, which was super easy. Once I landed, I switched off my primary sim and turned on my Orange eSim. However, I did this while still on the plane. If you know anything about my Germany trip, my carry-on suitcase was accidentally taken from a passenger on the plane. I was stressing out since I didn’t receive my local french number until after I connected to the local network. Therefore, the contact number on my luggage tag was my primary line that I had just turned off. Luckily, the gate agent for Air France helped me retrieve my suitcase. Thank you Air France!

For my trip to Portugal, I waited to switch to Airalo’s eSim until after I arrived at my Airbnb. I used a $10 International day pass from my cell phone provider the day of my travel so that I can ensure that I had access to my primary phone number while traveling. I would say using the day pass and waiting to switch my sims until I was at my accommodation made for a way less stressful travel day!

Using an eSIM comes with its own set of advantages and disadvantages. Here’s a rundown of the pros and cons:

Pros:

1. Convenience

   • You don’t need to handle or swap out physical SIM cards, making it easier to switch carriers or plans. Many eSIM-enabled devices support dual SIM functionality, allowing you to have multiple lines on one device (e.g., one for work and one for personal use).

2. Space Efficiency

   • Since eSIMs are embedded, they save space inside the device, allowing for potentially slimmer designs or more room for other features.

3. Faster Data Speeds

   • Connecting to a local network can provide faster data speeds than using your home cell phone provider’s international data plan.

4. Easy Activation

   • You can activate or change carriers remotely, often by just scanning a QR code or downloading from an app, which is especially useful for international travel.

Cons:

1. Carrier and Device Compatibility

   • Not all carriers and devices support eSIMs, so you may face limitations in certain regions or with older devices.

2. Initial Setup Complexity

   • Setting up an eSIM can be less intuitive than inserting a physical SIM card, especially if you’re unfamiliar with the process.

3. Potential Troubleshooting Challenges

   • If something goes wrong with the eSIM provisioning or activation, resolving issues might be more complex compared to swapping a physical SIM.

4. Lack of Contact Information

   • By turning off your primary line, your primary phone number cannot be used as contact info in case of emergencies. Some eSim providers that include a local phone number may not be provided until you connect to the local network after full day of travel.

Overall, eSIMs offer a modern, convenient solution for managing mobile connectivity while traveling abroad, but think about your needs while traveling to determine if this is the solution for you.
