Imagine upgrading to a new iPhone without ever having to swap a physical SIM card. eSIM technology is transforming the way people stay connected, offering convenience, flexibility, and security.
Whether you are a frequent traveller, a business professional, or simply someone who values a more simplified mobile experience, understanding eSIM has never been more important. By the end of this blog, we will have explored everything from activation and transferring numbers, to international use and business considerations - helping you make the most of your device.
What is eSIM and Which iPhone Models Support It?
An eSIM, or embedded SIM, is a digital alternative to the traditional physical SIM card. It allows you to activate a mobile plan directly on your iPhone without the need for a physical SIM card. Customers can store multiple eSIMs on a single device and even use two numbers simultaneously. This means you can have separate work and personal lines, or manage multiple business lines, without juggling devices.
The latest generation of iPhone, and iPhone XS, XS Max and XR or later, support eSIM.
How to Activate an eSIM on iPhone
Activating an eSIM on iPhone is simpler than you might think, with several options available depending on your carrier.
Carriers who support eSIM Quick Transfer make it easy to move your number to a new iPhone, and when they also support eSIM Carrier Activation, they can digitally assign your eSIM directly to your device.
eSIMs can also be activated by scanning a QR code provided by carriers or downloading through a carrier app. In some regions an ID check or a visit to a carrier store may be required for verification, while business customers may need to contact their administrator or carrier.
How Can I Transfer My Number and Manage Multiple eSIMs?
One of the most appealing features of eSIM is the ease of transferring phone numbers. If you are upgrading from an previous iPhone, carriers who support eSIM Quick Transfer allow you to migrate your number without changing your plan, as long as both iPhones are nearby and on the same network. Android users switching to iPhone can also transfer their number via eSIM Carrier Activation, QR code, or a carrier app. Once activated, the previous SIM is immediately deactivated, preventing any overlap or confusion.
iPhones can store eight or more eSIMs, allowing you to manage multiple numbers from a single device. This is ideal for professionals who need separate lines for work and personal use, or for those who frequently travel internationally and require temporary plans. It is important to transfer your eSIM to your new iPhone before trading in an old device, ensuring uninterrupted connectivity and a smooth transition.
Can eSIM be Used for Travel and International Use?
For travelers, eSIM offers unmatched convenience. With an unlocked eSIM-compatible iPhone, you can connect to carriers worldwide without swapping physical SIM cards. Customers can even set up a travel eSIM from a local carrier or worldwide service provider before leaving the country, providing instant connectivity on arrival. Roaming works the same as with traditional SIMs.International roaming works the same on an eSIM as it does with a physical SIM, and many carriers offer convenient and affordable international roaming plans.
International business users will also benefit from the flexibility of eSIM. You can maintain your primary number for work, while using a local eSIM in another country for data and local calls. This eliminates the need to carry multiple devices or worry about excessive roaming charges, making eSIM a truly global solution for staying connected.
A Smaller Change with a Big Environmental Impact
Beyond convenience, eSIM technology also supports a more sustainable future, by removing the need for physical SIM cards. With fewer cards being manufactured, shipped, and replaced, eSIMs contribute to reducing carbon emissions across the supply chain.
