Core Insights - The overall experience of activating eSIM for the domestic version of iPhone Air in China is not ideal due to initial operational challenges and policy restrictions, although the efficiency of the process is commendable [2][10]. Group 1: eSIM Activation Process - The process of converting a physical SIM to eSIM is similar to that of traditional SIM activation, requiring the submission of identification and old phone numbers [3]. - The writing process for eSIM takes less than 5 minutes, with additional time spent on introductions and signing agreements [4]. - Users can still use their physical SIM until the eSIM is activated, at which point the physical SIM will be deactivated [7]. Group 2: Regional Limitations - Despite announcements suggesting cross-regional activation, users found that eSIM conversion is not possible across provinces, requiring users to be in their number's registered area for activation [8][9]. - This limitation poses challenges for users in major cities who may not reside in their number's registered area [9]. Group 3: Roaming and External SIMs - The eSIM experience for international roaming remains unchanged compared to physical SIMs, with no noticeable differences [14]. - The domestic version of iPhone Air cannot activate eSIM services from foreign carriers, and the ability to activate foreign eSIMs while abroad is uncertain [15][17]. Group 4: Cost and Package Changes - There are no additional fees for converting from a physical SIM to eSIM, although some users reported a temporary charge that was refunded [20][21]. - Existing packages can be retained without changes or additional fees when switching to eSIM [22]. Group 5: eSIM Migration - Users must visit a service center to migrate eSIM to a new device or revert to a physical SIM, which requires identity verification [26]. - Each migration counts against the monthly limit of five card replacements per user [27]. Group 6: User Experience and Staff Training - The activation and migration process for eSIM in China is perceived to be more cumbersome compared to experiences with overseas carriers [30]. - Staff training for eSIM services has been rushed due to the sudden launch of the iPhone Air, leading to potential inefficiencies [32][33].
