What is an eSIM?
Historically, SIM cards were small chips that you had to insert into your phone to connect to your cell network. Now, eSIMs are a digital version of those cards, already built into your phone.
The market for eSIMs is expected to expand rapidly in the coming years, with Juniper Research projecting a 410% growth from 2024 to 2028.
Can I make phone calls with an eSIM?
The ability to make phone calls with an eSIM depends on the specific eSIM plan you choose.
Instead of traditional phone calls and texts, many eSIM plans offer data-only access to the web and apps. To avoid roaming charges, you can use web-based apps like Facetime or WhatsApp.
Some eSIMs come with a phone number that enables calling and texting, and the specifics of these offerings may vary.
How to check if your phone is eSIM compatible
To ensure a seamless eSIM experience during your trip, confirm that your phone is compatible. Most modern smartphones, including iPhones (XS and later), Samsung Galaxy, and Google Pixel, support eSIMs. If your phone is older, verify compatibility before purchasing an eSIM, as many providers list compatible devices on their websites.
If your phone is locked into a specific carrier, you may encounter difficulties when using a carrier-unlocked phone.
The installation process for an eSIM is typically straightforward and involves downloading an app and following instructions or scanning a QR code after purchase.
Pros and cons of using an eSIM
An eSIM can simplify travel for many people, but it's important to be aware of a few things.
Pros of eSIMs
- No physical card means no risk of losing, breaking, or having your eSIM stolen.
- Instead of visiting a local store to purchase physical SIM cards, you can now download an eSIM.
- Up to 8 eSIMs can be stored on an iPhone, enabling users to utilize two of them simultaneously.
- You can easily refill your eSIM online without purchasing a new physical card when your limited plan runs out of data.
Cons of eSIMs
- Data-only plans are the only option available for many eSIMs, meaning you'll have to use the internet to make calls.
- Transferring eSIMs to another phone is more challenging because there is no physical card to swap. This makes the process of switching eSIMs back and forth a bit more complicated.
- Unlimited data plans may limit your speeds if you use too much data, as per fair use policies.
What to consider when choosing an eSIM
When deciding on an eSIM, it's important to consider a few general factors.
- Before selecting an eSIM, ensure that your device is compatible and not restricted by your carrier.
- Some eSIM providers may offer better plans or coverage in specific regions of the world compared to others, depending on your destination.
- Before signing up for an eSIM plan, consider the duration and amount of data you'll use to determine the fluctuating cost.
- Determine the length of your plan and whether a data-only option or one that includes calls and texts is more suitable for your needs.
- Having a robust customer support system can be advantageous when using your eSIM in a foreign country and encountering any issues.
