At present, both China Unicom and China Telecom do not provide inter-provincial eSIM transfer services. Users who were among the first to purchase the Apple iPhone Air must return to the province where their phone number is registered to carry out eSIM-related operations. However, they have the option to activate a new eSIM plan locally. Utilizing an eSIM card incurs no additional charges, but a processing fee applies if users decide to switch back to a physical SIM card. This morning at 9 a.m., the domestic version of the Apple iPhone Air became available for pre-order, with prices starting at 7,999 yuan. The initial batch of stock was depleted within minutes. IT Home cautions that it remains uncertain whether the domestic iPhone Air model will support the long-term use of overseas eSIMs, or whether it will facilitate overseas eSIM roaming services while in mainland China. Consumers with specific needs in this regard are advised to await further testing results before proceeding with a purchase.
