What does eSIM mean?

eSIM stands for embedded SIM. Unlike traditional SIM cards that you physically insert into your phone, an eSIM is built directly into your device’s hardware. It stores your mobile plan digitally, allowing you to easily connect to a network without needing to fuss around with a removable card. Because it's embedded, an eSIM can be activated remotely, and you can store multiple eSIMs at once, making it much more flexible than the old plastic SIM cards that you’d have to manually insert.

How does an eSIM work?

When it comes to how eSIMs work well, they’re almost exactly the same as regular SIMs. The main differences are that instead of using a physical card, an eSIM card is a small chip embedded in your phone, and it can’t be removed. You can also have plans with multiple networks on the one phone with an eSIM.

To set up an eSIM, your carrier will usually send you a QR code or activation details that you scan to download your mobile plan directly onto your phone. This process is called remote provisioning, and it allows you to add, change, or remove plans without touching a physical SIM.

Benefits of using an eSIM

Switching to an eSIM brings a whole host of practical benefits that make everyday use more flexible and hassle-free. If you’re a frequent traveller, eSIMs make it easy to add a local data plan without swapping out physical SIM cards, which is ideal for avoiding pesky (and costly) roaming charges.

Dual-SIM functionality also means that you can run two numbers on one device, which is perfect for balancing work and personal life. So, if you need to switch mobile networks, it’s super easy to do – you can activate a new plan in minutes without visiting a store. Because there’s no physical card, manufacturers can save space inside your phone, leading to slimmer designs and better water resistance.

Plus, whether you’ve made the most of an iPhone deal or Galaxy deal, no matter the device you opted for, they’re considered to be more safe because eSIMs are encrypted and built to be tamper-resistant. This provides additional peace of mind as well as convenience. Win-win.

FAQs about eSIM

How many eSIMs can my phone have?

The amount of eSIMs you can have on your phone depends on the make and model of your current device. An iOS device (iPhones) can store up to eight eSIM profiles, but only two can be active at the same time.

If you have an Android device, the number of eSIMs you can install and have active at one time varies. Most allow for five to seven eSIMs, but again, you can only have two active lines simultaneously.

Can I remove or delete an eSIM?

Yes! You can delete or switch an eSIM easily in your phone’s settings.

On iPhone, go to Settings > Mobile Data, select the eSIM you want to remove, and tap Delete eSIM.

On Samsung, it’s under Settings > Connections > SIM Manager.

Are eSIMs secure?

Absolutely. eSIMs use strong encryption and tamper-resistant technology to protect your data. They’re just as secure as traditional SIM cards, if not safer, because they can’t be physically stolen or swapped without your knowledge.
