Why the New iPhone Air’s eSIM Is a Game‑Changer for China’s Mobile Market
The iPhone Air eliminates the physical SIM slot in favor of eSIM, prompting Chinese carriers to prepare support while highlighting which device models can use eSIM domestically and abroad, and explaining the trade‑offs for travelers.
Apple has been promoting eSIM internationally for a long time, allowing users to activate or cancel plans online without a physical SIM, which is convenient for travelers.
In mainland China, eSIM adoption has lagged, but the newly launched iPhone Air completely removes the physical SIM slot, using only eSIM.
Other iPhone models like iPhone 17 still use dual nano‑SIM slots and do not support eSIM.
Domestic carriers are ready:
China Unicom supports eSIM on the iPhone Air; users must visit a physical store with ID to activate, online activation is not available and other models are unsupported.
China Mobile has prepared for eSIM but has not opened the service yet.
China Telecom is fully prepared and expects to launch eSIM services, including for iPhone Air, after regulatory approval.
Which models can use Chinese carriers’ eSIM?
Currently only the mainland China version of iPhone Air (model A3518) supports eSIM with Chinese carriers. Foreign versions cannot activate eSIM in China, and the iPhone Air without a physical SIM cannot use cellular networks there.
The mainland iPhone Air also supports foreign carrier eSIMs when taken abroad, using a one‑way lock mode, so buyers should consider the trade‑off between physical SIM and eSIM.
Other versions with SIM + eSIM:
Japanese, Canadian, UAE versions of iPhone 17 series are eSIM‑only. Users wanting both eSIM and a physical SIM should consider Hong Kong, Australian, or Taiwanese versions, which provide one eSIM and one physical SIM.
This dual‑SIM setup allows continued use of a physical SIM domestically and eSIM abroad, which is currently the optimal solution for travelers.
