The iPhone Air is exclusively eSIM-capable and does not have a physical SIM slot. This makes it completely eSIM-only. You can store multiple eSIM profiles on the device and actively use up to two eSIMs simultaneously (Dual eSIM). It is not possible to use a physical SIM concurrently, as there is no slot. Setting up your BuddySIM eSIM is convenient via QR code scan or Apple Universal Link (from iOS 17.4). Multiple eSIM profiles can be stored (8 or more), but two eSIMs can be active simultaneously. Please note: The range of functions may vary depending on the country. iPhone Air models purchased in Germany allow the simultaneous use of up to two eSIMs. In mainland China, the market launch is delayed as eSIM usage is restricted by regulations. Currently, only China Unicom supports the iPhone Air with eSIM. In Hong Kong and Macao, iPhone Air models are also not eSIM-capable at present, as Apple does not offer an eSIM version there. This makes the iPhone Air one of the first devices from Apple worldwide to rely exclusively on digital SIM technology, thus consistently advancing the future without plastic SIMs.

How to set up your eSIM

Easily from home
1
Check compatibility & buy eSIM
Make sure your iPhone Air supports eSIM, and buy your eSIM in the BuddySIM shop.
2
Install eSIM
Settings → Mobile Data → Add eSIM → enter the activation details from your email or scan the QR code.
The eSIM's mobile data only activates in your destination country — before that an error message may appear. That's normal, since the data is intended for your destination only.
Activate
Only in your destination

Frequently asked questions
What is an eSIM?
An eSIM (embedded SIM) is a digital SIM card already built into your smartphone. You no longer need to insert a physical SIM card – everything works digitally via QR code.
Can I use my regular SIM card at the same time?
Yes! Your iPhone Air supports dual SIM. You can use your regular SIM card alongside the eSIM – perfect for travelling or to separate personal and business numbers.
How long does activation take?
The eSIM is activated within seconds. Right after purchase you receive the QR code by email and can scan and use it immediately.
Does BuddySIM work worldwide?
Yes, BuddySIM offers eSIM data plans for over 190 countries worldwide. Just choose your destination and stay connected anywhere.
Do I need a new number?
No! BuddySIM eSIMs are data-only plans. You keep your existing number on your physical SIM card and use the eSIM just for mobile internet.
Your iPhone Air stores 8 or more eSIM profiles. From the iPhone 13 you can use two eSIMs active at the same time (Dual eSIM); on older models one eSIM is active – combinable with a physical SIM.
