We have all seen that as technology advances, eSIM technology becomes something which rapidly replaces traditional physical SIM cards, which offers greater flexibility and convenience for users. So, if you own an iPhone and watch to switch to an eSIM; this guide will walk you through the eSIM installation and activation process, step by step.
What is an eSIM?
An eSIM (Embedded subscriber identity module) is a digital SIM embedded into your iPhone, which allows you to connect to a mobile network without actually using a physical SIM card. With an eSIM, you can very easily switch between carriers, manage multiple phone numbers, and even use international plans without swapping SIM cards.
How to Install an eSIM on your iPhone
There are several methods to install an eSIM on your iPhone, depending on your carrier's potential setup options:
1. Direct eSIM Installation via Apple Universal Links
With the release of iO 17.4, Apple has now introduced a seamless way to activate an eSIM using Universal Links:
- You can receive a universal link from your eSIM carrier via email or SMS.
- Then you can tap the link on your iPhone and start the eSIM installation process.
- Follow the on screen prompts, and then your eSIM profile will be added automatically.
- This is by far the fastest way to activate an eSIM on those iPhones which support it.
2. QR Code eSIM Activation
If you carrier can provide you with a QR code, you can install your eSIM by simply scanning it:
- Open Settings --> Cellular --> Add Cellular Plan
- Choose Use QR Code and scan the code using your iPhone camera
- Wait for the eSIM profile to download and activate the eSIM
- Set your default line for calls, messages, and data.
This method is most commonly used by global eSIM providers, such as Mobimi, Holafly and Airalo.
3. Manual eSIM Installation
If a QR code or Universal Link is unavailable, you can enter your eSIM details manually:
- Go to Settings --> Cellular --> Add Cellular Plan
- Select 'Enter Details Manually'
- Input the SM-DP+ Address, and Activation Code, which will be provided by your carrier.
- Follow the instructions to complete the eSIM activation.
This will ensure that you can set up an eSIM even if other methods are not available to you.
How to Activate an eSIM on iPhone
After installing your eSIM, you need to then activate it in the following way:
Go to Settings --> Cellular, and ensure that your eSIM line is enabled.
Set your eSIM as the primary or secondary line based on your preference.
Restart your iPhone completely if necessary, to ensure network connectivity.
Benefits of Using an eSIM on iPhone
Switching to an eSIM offers several advantages:
Convenience: There is no need for an actual physical SIM card.
Dual SIM capability: Use two phone numbers instead of one on a single iPhone.
Easy Carrier switching: You can activate your new plans remotely.
Great for travellers: Get local eSIM plans when abroad, without changing SIM cards.
eSIM Adoption and Challenges
While eSIM technology is growing, its adoption varies across regions. In Germany, only 13% of smartphone users currently use eSIMs, while in the US, Apple has made its latest iPhone 16 modls eSIM only. This is a transition which may cause frustration for users who rely on physical SIM cards, especially when travelling to areas with limited eSIM support.
