eSIM – everything you need to know about the SIM card of the future

Are you still fiddling with the small plastic card in your mobile phone? If you haven't gotten to know eSIM yet, it's about time. Get information about the technology, the benefits of eSIM, and how Telavox can help you get started with the SIM card of the future! 

What is eSIM?

The abbreviation eSIM stands for embedded sim and thus means that the SIM card is built into a mobile phone, smartwatch, or tablet. This means you don’t need the traditional plastic SIM card you place in the mobile phone manually. Chips that are built into phones are about 60 times smaller than traditional SIM cards. Since eSIM only requires a small component on the device's motherboard, the phone has more space to include a larger battery or better camera hardware.


eSIM support is standard in the newer generations of smartphones. Some examples of smartphones that support eSIM:

  • All iPhones from 2018 (iPhone XS) onwards

  • Samsung Galaxy series S20-S22

  • All Google phones since the Pixel 3a

The future of eSIM

The global infrastructure for eSIM is well-developed today, and more operators are investing in the technology. According to a study by Juniper, the number of installed eSIMs will increase from 1.2 billion in 2021 to 3.4 billion in 2025. The study shows that as established consumer device vendors such as Apple and Google adopt the technology, eSIM growth will also continue to accelerate for the industrial and public sectors.


Apple started working with eSIM when the Apple Watch 3 was launched with a cellular connection. Apple announced in 2022 that they will remove physical SIM cards from its iPhone 14 models in the US. That means that the process towards a world free of plastic SIM cards is underway, because we know that Apple has a tendency to set the trends in the smartphone industry.


Google, on the other hand, has offered eSIM support in its phones since the Pixel 3a. With Android 13, they introduced support for Multiple Embedded Profiles (MEP), meaning that only one eSIM module is required on the phone to support multiple eSIM lines.

4 clear eSIM advantages

1. Super easy to install

The previously unwieldy plastic card is now built into the phone. Users don't have to wait for the supplier to send a physical card, which means that it's not only easy to install – it's a rapid process allowing you to start using it directly!


2. Increased flexibility

Thanks to eSIM, you, as a supplier, can spend less time on administrative tasks like packing the SIM cards and sending them to the right user. With eSIM, it also becomes more accessible for employees to temporarily change operators when they’re traveling with a company phone and thus avoid expensive roaming costs.


3. Use two SIM cards with Dual SIM

Do you use two different mobile phones – one for work and one for private use? With eSIM, you don't have to switch between several phones as you have eSIM and a physical SIM card in the same phone. You can thus set up your phone so that calls are made, or text messages are sent from your private number and others from the work number.


eSIM provides you with the option of having two active mobile numbers at the same time. However, you can only have one active eSIM at a time.


4. Environmentally friendly and a future-proof solution 

eSIM requires no manufacturing or transport, so it's excellent for both users and the planet. Physical SIM cards can also wear out over time and must be replaced.


An even worse situation is if the phone with the physical SIM card is stolen. That can lead to data leaks if the phone is not password protected. eSIM can help you find your lost phone, even if you haven't set up functions like "Find my iPhone." The operator of your eSIM has access to the data and can help locate your device or block the eSIM card if necessary.
