How does an eSIM work?
eSIM technology is changing the way people connect to mobile networks by simplifying the process of switching carriers and plans. We’ve summarized how eSIMs work.
eSIM stands for “embedded SIM”, which is a feature of most smartphones and tablets manufactured today. Think of it as the digital evolution of the SIM card – giving you everything you need to connect without having to swap out pieces of plastic.
What is an eSIM and how does it work?
In simple terms, an eSIM is a small chip embedded directly into mobile devices like smartphones, tablets and smartwatches.
eSIMs are reprogrammable, but SIM cards are only programmed once and then thrown away when no longer needed.
eSIM chips can’t be replaced or removed, but you can store and delete eSIM profiles when you need them.
How do eSIM profiles work?
An eSIM profile is a small piece of software that gets downloaded and installed onto an eSIM chip. This contains critical information that allows your device to access your chosen carrier’s network.
This chip can be programmed with multiple eSIM profiles (usually up to 7, 8 or more) that contain all the information needed to connect to a mobile network, including your phone number, plan details, and carrier information.
This means that you no longer need different physical SIM cards to connect to different networks – everything is stored digitally on the eSIM chip.
What does eSIM mean for your digital experience?
eSIMs take the effort out of changing mobile plans because they are fully digital (unlike plastic SIM cards). What eSIM means for users is a much more streamlined and effortless experience.
- Faster switching: no more time wasted visiting a shop or waiting for a new SIM card to arrive in the mail. Just download your new plan from anywhere.
- No accidental damage: you can’t use SIM cards that get lost, damaged or dirty. eSIMs never have this problem.
- Easier install: activating your eSIM is much easier than opening a SIM tray, unpackaging a new SIM card and not dropping it on the floor.
- Unlimited choice: your traditional SIM card limits you to the plans that support that specific card. With an eSIM, you can easily switch between virtually any mobile plan with just a few clicks.
- Better security: the key ‘Subscriber Identity Module’ information on an eSIM is stored digitally on the chip, so it’s less susceptible to physical damage or theft. They can also be remotely managed and updated by eSIM providers.
