What is an eSIM? eSims explained

An eSIM (embedded SIM) is a type of SIM card that is embedded directly into a device, such as a smartphone or tablet, instead of being a physical card that can be removed and replaced. An eSIM allows users to activate and switch between different mobile phone plans or carriers without the need to physically swap out SIM cards.

The biggest advantage is that you can keep your existing cell phone / data plan and add a new cheaper plan for example when traveling abroad. Both plans get to run on your phone side by side and you can choose what plan handles data and what plan handles calls. You can also opt to turn off your regular plan entirely while traveling and just use the eSim / cheaper plan.

It that it allows users to easily switch between different carriers or plans without the need to physically remove and replace the SIM card. This can be especially convenient for travelers who need to switch to a local carrier while abroad, or for users who want to switch between different plans without the hassle of physically changing SIM cards.

It is important to note that not all devices are compatible with eSIM technology, and availability may vary by region. It is always a good idea to check with your device manufacturer or carrier to determine if an eSIM is an option for your device.
