What is an eSIM? KnowRoaming eSIM review

An eSIM (embedded SIM) is a software-based digital SIM that allows you to activate a cellular plan from your carrier without having to use a physical nano-SIM.

Unlike a physical SIM card, an eSIM is embedded directly into the device. There’s no need to insert a card to activate the service. Instead, you can download a cellular plan directly to the eSIM using a QR code or through an app.

Here’s how eSIMs work: KnowRoaming eSIM review

  • The eSIM contains your phone number, service plan, and other data typically stored on a physical SIM card. But instead of being on a removable chip, it’s integrated into the device’s hardware.

  • To activate the service, you scan a QR code or enter an activation code provided by your carrier. This securely transfers your service plan to the eSIM.

  • Once activated, the eSIM connects to the carrier network and provides service just like a regular SIM card would. You can switch plans or carriers directly on the eSIM without swapping any cards.

eSIMs offer several benefits over traditional physical SIM cards:

  • Convenience – No need to obtain, insert, or replace a physical card. It is easy to add or change plans remotely.

  • Dual SIM – Have two plans (personal & business) active simultaneously when the phone supports dual eSIM.

  • Security – Reduced risk of SIM swapping fraud. eSIM is deeply integrated into the device.

  • Global roaming switch carriers as you travel across borders. Roaming agreements are not needed.

So in summary, an eSIM provides the same functionality as a physical SIM but in an embedded digital form within the device. This allows more flexibility and convenience when managing cellular plans.
