Embedded SIM (eSIM) technology allows mobile users to download a carrier profile and activate a service without having a physical SIM card.
eSIM-enabled smartphones, including iPhones and Android phones, let customers do this digitally by scanning a QR code.
The Android framework provides standard APIs for accessing and managing eSIM subscription profiles, as well as for local profile assistants (LPAs) that help the user manage their profiles on the eSIM.
How to download an eSIM
If you're looking to get connected to the cellular network on your smartphone or laptop, you can download an eSIM profile. This allows you to manage your cellular plan on your device without having to use the physical SIM card that is usually shipped in the box with the phone.
An eSIM profile is usually in the form of a QR code that you can scan with your phone or tablet's camera to install and activate it. The process takes a few minutes to complete, and then you're ready to go!
Alternatively, you can download an eSIM from the website of your carrier. They will often send you a confirmation email with a QR code in it that you need to scan to activate your eSIM.
How to activate an eSIM
An eSIM is an industry-standard digital SIM that's built into your phone. It's a lot easier and more secure to use than a physical SIM card.
Typically, a carrier will provide you with an activation code to download an eSIM profile. The code is often in the form of a QR code that you'll scan with your smartphone to install and activate your eSIM profile.
In most cases, it takes a few minutes to download and install the profile. You can also swap operators without having to remove and replace the eSIM - which makes it very convenient for travelers!
The process differs depending on whether you're adding a new line or changing a device. It also depends on your phone and carrier.
How to install an eSIM
You can install an eSIM on your iPhone in just a few simple steps. It’s a digital alternative to a physical SIM card that allows you to add cellular plans and use multiple phone numbers from different carriers.
You’ll also be able to configure things like labeling and data roaming at any time, making it easier to manage your phone’s wireless network usage. Plus, an eSIM makes it harder for someone to remove your physical SIM card.
If you’re switching to an iPhone with an eSIM, it’s important to remember that you’ll need Wi-Fi connectivity for the installation and activation process to work correctly. If you’re planning on traveling to a country without Wi-Fi support, you can install an eSIM on your device before leaving and activate it at your destination.
How to remove an eSIM
If you want to erase an eSIM from your device, there are a few different ways. It's a good idea to check with your carrier before doing this.
Unlike a physical SIM card, eSIMs are embedded in your smartphone or other device's motherboard. They're also more difficult to remove.
One of the biggest benefits of eSIMs is that they're rewritable, which means you can switch to a new operator without having to change the number or wait for a new SIM chip to arrive.
Another benefit is that eSIMs are able to transfer data, which is a big deal when your phone gets lost or stolen. Instead of having to pop out the SIM card, you can retrieve your address book and media files from a cloud storage service.
You can also erase an eSIM when you're selling or trading your iPhone, transferring the number to a new device, or when you're changing plans. It's a good idea to make sure you've set up the new cellular plan before removing the eSIM, though.
