With the introduction of eSIM technology, Apple has launched a significant innovation for iPhone users. The eSIM, a digital SIM card, not only gives you more flexibility in managing your mobile phone plan but also allows you to use multiple phone numbers on one device at the same time. In this article, you'll learn everything you need to know about eSIM on iPhone: from the basics to setting it up and converting your physical SIM card to an eSIM. This comprehensive guide will help you get the most out of eSIM technology and improve your iPhone experience.
The eSIM (embedded SIM) is more than just a technical gimmick - it is a decisive step towards a fully digital mobile future. This technology eliminates the need for physical SIM cards and opens up new possibilities, such as managing multiple mobile phone plans on a single device, easily changing plans or seamlessly using international services. In times when mobility and flexibility are becoming increasingly important, the eSIM is a valuable tool for anyone who wants to use their iPhone more efficiently and in more ways.
What is an eSIM on the iPhone?
The eSIM is a digital SIM card that is permanently installed in your iPhone. Unlike a conventional, physical SIM card that you have to insert into the SIM card slot of your device, the eSIM is activated electronically. This means that you can set up your mobile phone plan directly on your iPhone without needing a physical card. Particularly practical: You can save up to eight or more eSIM profiles on one iPhone and use two phone numbers at the same time. This function is ideal for people who use different numbers for work and private purposes or who travel a lot and want to use local tariffs.
Requirements for using the eSIM
Before you can use eSIM technology on your iPhone, there are a few requirements that must be met:
- Device compatibility: The eSIM feature is supported on iPhone models starting with the iPhone XS, iPhone XS Max, and iPhone XR. Newer models, such as the iPhone 14 and later, offer enhanced features for the eSIM.
- Mobile operator: Your mobile operator must support eSIM technology. Many operators worldwide now do, but it's a good idea to check first.
- Network connection: Setting up the eSIM requires that your iPhone is connected to a Wi-Fi network. However, there is one exception: For iPhone 14 models and newer, a Wi-Fi connection is not required to activate the eSIM.
- Regional restrictions: In some regions, such as mainland China, eSIM technology is not available on iPhone. In Hong Kong and Macau, however, some models offer the option to use an eSIM. However, travelers to China can use prepaid data plans through global service providers.
Setting up the eSIM on the iPhone
Setting up the eSIM on your iPhone is a simple process that usually only takes a few minutes. Depending on your carrier, there are different methods you can use to activate your eSIM.
- Automatic eSIM assignment at purchase: When you buy a new iPhone, your carrier may already assign an eSIM for you. In this case, just turn on your iPhone and follow the onscreen instructions to activate the eSIM.
- Quick eSIM transfer from an old iPhone: If you're upgrading from an older iPhone to a new one, you can easily transfer your eSIM without contacting your carrier. Both iPhones must be running iOS 16 or later and signed in with the same Apple ID. Your old iPhone must be nearby, unlocked, and have Bluetooth turned on. Follow the onscreen instructions on your new iPhone to transfer the eSIM.
- eSIM activation by your carrier: Some carriers support eSIM activation directly from your carrier. In this case, your iPhone will automatically receive an eSIM when you purchase it, which you can activate during setup. When you contact your carrier to activate the eSIM after purchasing a new iPhone, you may receive a message saying "Cellular plan ready to install." Tap it to activate the plan on your device.
- Use a QR code: Another way to activate your eSIM is to use a QR code provided by your carrier. Just open the Camera app on your iPhone and scan the code. Follow the onscreen instructions to activate your eSIM. If you're using an iPhone with iOS 17.4 or later and you receive a QR code from your carrier via email or from the carrier's website, press and hold the QR code, then tap Add eSIM.
Converting a physical SIM card into an eSIM
If you already have a physical SIM card, you can convert it to an eSIM on the same iPhone, provided your carrier supports this feature. Here's a step-by-step guide on how to do it:
- Open the settings: Go to “Settings” on your iPhone and select the “Cellular” section.
- Convert to eSIM: If your carrier supports conversion, you will find the option “Convert to eSIM”. Tap it to start the process.
- Convert mobile phone plan: Confirm the conversion by tapping "Convert mobile phone plan". Your iPhone will now transfer the plan from the physical SIM card to the eSIM.
- Activate eSIM: Wait until the eSIM is activated. Once this happens, the old SIM card will be deactivated.
- Remove physical SIM card: After the eSIM is activated, you can remove the physical SIM card from your iPhone and restart the device.
Additional eSIM activation methods
In addition to the methods described above, there are other ways you can activate your eSIM:
- eSIM activation link: Some carriers may send you a link to activate your eSIM. Simply tap the link to set up the eSIM on your iPhone - requires iOS 17.4 or later.
- Activate eSIM via an app: If your mobile operator offers a special app for activating the eSIM, you can download it from the App Store and follow the instructions.
- Manually enter eSIM details: In rare cases, it may be necessary to manually enter eSIM details. To do this, go to your iPhone's Settings, select Cellular, then Add Cellular Plan. Tap Enter Details Manually and enter the required information provided by your carrier.
Dual SIM function with eSIM and physical SIM card
One of the biggest advantages of eSIM technology is the ability to use dual SIM functionality. This means you can activate an eSIM and a physical SIM card on your iPhone at the same time. This feature is especially useful if you use two different phone numbers - for example, a personal and a work number - or if you travel abroad often and want to use a local plan without giving up your main number. On newer iPhone models, you can even activate two eSIM cards at the same time.
