What is an eSIM and How Does It Work?

Your train is delayed, and you're impatiently waiting for the train at the station in the middle of Paris when the Wi-Fi signal fails. You really want to get your ticket, get the updates from your group chat, and find directions to your accommodation in the city.

Just remember how you moved from traditional DVDs to online movies and changed from keychains to smart locks. In both cases, you do not lose anything valuable; you only rid yourself of the wearisome intermediary. If you are going to travel soon, make sure you know everything about connectivity and avoid extra charges for roaming services.

What is eSIM?

So, what are eSIMs? eSIMs, or embedded Subscriber Identity Modules, are small chips that are placed into the phone’s motherboard during its manufacturing.

Think of an ordinary SIM card as being a hotel physical key card. You go to reception to pick it up and must keep it on you whenever you are moving from one hotel room to another. An eSIM works like a hotel pass sent through the app to your phone, and hence the lock remains the same, while the permissions change almost instantly. There is no need for you to open a tiny tray and insert a small piece of plastic into the phone.

How Does an eSIM Work Behind the Scenes?

When examining how eSIM works, one needs to keep in mind the interplay between three important components:

eUICC chip: The chip is physically installed on your mobile phone. It is a blank digital container ready to accommodate network profiles.

eSIM profile: The profile contains information about your mobile service plan, data limit, and network credentials.

Remote provisioning: Remote provisioning is the secure software process through which the operator downloads the network profile directly to the mobile phone over the Internet.

Upon purchasing a travel plan from SIMZY, you are provided with a unique setup QR code, which makes your phone download the profile into its eUICC chip. The moment your plane lands, your phone connects to the local network of either 4G or 5G towers.
