What is an eSIM?

An eSIM, or “Embedded Subscriber Identification Module”, is a chip that is embedded inside a range of devices and can be activated with cellular services, including data and/or voice and SMS.

How does an eSIM work?

An eSIM functions exactly like a physical SIM card, in that it stores subscription data and can be used to connect your phone to cellular services. However, unlike a traditional SIM card, an eSIM is embedded within a device during its manufacturing stage and cannot be removed. Uniquely, eSIM services are downloaded via the internet (remotely provisioned) from a user’s chosen eSIM provider and can be rewritten at any time should the user wish to change their provider or services plan.

What is an eSIM used for?

The majority of eSIM plans on the market are data-only bundles, ideal for those looking to add data services to their eSIM-enabled tablet, or when traveling overseas as they offer extremely low international roaming rates. However, have recently been the first provider to offer a Global Pay As You Go eSIM plan which comes with a telephone number for voice calls, and SMS and data services. This plan is suited to those who require an active, second mobile line on their smartphone when traveling overseas.

Will an eSIM work with my current SIM card?

eSIM services on a handset work concurrently with an existing SIM card, meaning there is no need to remove your existing SIM or lose your personal, private number. Whether you opt for data-only eSIMs or an eSIM plan with voice, SMS and data, you’ll be able to use both SIM options at the same time. Moreover, depending on your eSIM provider, you may be able to switch between mobile networks and even have two different mobile networks working on your phone at once.
