eSIM手机来了!三大运营商均支持

A significant shift is underway in mobile technology with the rise of eSIM. Unlike traditional physical SIM cards, an eSIM is a digital chip embedded directly into a device. It replaces the physical card with an electronic profile, allowing users to activate cellular service (移动网络服务) without visiting a store for a SIM card. This technology enables switching between mobile carriers, frees up valuable internal space for larger batteries or improved components, and often enhances the device’s water resistance.

This technological advancement has now gained official momentum in China. On October 13, the country’s three major carriers — China Unicom, China Mobile, and China Telecom — announced they had received approval to begin commercial trials of eSIM services for mobile phones, marking a nationwide rollout across mainland China. The carriers highlighted key advantages of eSIM, including high security, stability, and the flexibility it offers. This technology paves the way for a more convenient user experience, featuring card-free activation, multi-device connectivity, and easier global roaming (漫游).

Public anticipation for this new service is evident. Even before the official launch, pre-registration channels offered by China Mobile and China Unicom saw overwhelming demand, with hundreds of thousands of users signing up within hours. To apply for the service, users can currently visit the offline stores of carriers like China Mobile and China Telecom.

The move also fuels speculation (猜测) about new device launches, most notably Apple’s ultra-thin iPhone Air. This device, which has completely eliminated the physical SIM slot in favor of eSIM, may soon see an official release in the Chinese market. The groundwork for this shift has been laid over years. China Unicom, for instance, began its eSIM research as early as in 2015 and has since expanded the technology to wearables, laptops, and IoT devices, serving millions of users. Beyond the iPhone Air, domestic manufacturers like Huawei and OPPO are also expected to launch their own eSIM-compatible phones soon, signaling a broad industry transition towards a more integrated and flexible mobile future.

1.1. What is a key advantage of eSIM technology mentioned in the first paragraph?

A Lower cost for users.

B Free international roaming.

C More internal space for components.

D Longer battery life immediately.

解析:选C。C细节理解题。根据第一段最后一句“This technology... frees up valuable internal space for larger batteries or improved components...”可知,eSIM技术的一个关键优势是为更大的电池或改进的部件释放了宝贵的内部空间。C选项与此完全一致。A(用户成本更低)、B(免费国际漫游)和D(立即延长电池寿命)在文中均未提及。故选C。

2.2. The approval from Chinese carriers implies that eSIM service is ______.

A still in early testing

B available across the nation

C required for all users

D only for Apple devices

解析:选B。B推理判断题。根据第二段中的“commercial trials”与“marking a nationwide rollout”并举,说明尽管名为“试验”,但其性质是面向全国范围的正式商用推广。B选项(全国可用)最符合此深层含义。A(仍在早期测试)与“全国推广”的定位不符;C(对所有用户是必需的)和D(仅限苹果设备)在文中均无依据。故选B。

3.3. What can be inferred about users’ attitude towards eSIM?

A Positive.

B Negative.

C Unconcerned.

D Doubtful.

解析:选A。A推理判断题。根据第三段的“China Mobile and China Unicom’s eSIM pre-registration channels saw strong demand, with hundreds of thousands of users signing up within hours”(中国移动与中国联通的eSIM预约通道需求旺盛,数小时内数十万名用户注册)。“需求旺盛” 和 “快速大量注册” 体现用户对 eSIM 服务的迫切期待,可间接推断态度为积极。B(消极)、C(漠不关心)、D(怀疑)均与文本描述的用户行为矛盾 —— 若态度消极或冷漠,不会出现 “大量注册” 现象。故选A。

4.4. What is a future trend suggested by the passage?

A Physical SIMs’ immediate end.

B The eSIM becoming a standard feature.

C Free global roaming for all.

D The eSIM limited to premium brands.

解析:选B。B推理判断题。文章结尾指出,除苹果外,华为、OPPO等国内厂商也将推出eSIM手机,这标志着整个行业向更集成、灵活的未来转型。因此可合理推断,eSIM将成为一个主流或标准配置。B选项(eSIM成为标准功能)符合此推断。A(实体SIM立即终结)过于绝对;C(所有人免费全球漫游)是过度推断;D(eSIM仅限于高端品牌)与文中多家厂商跟进的描述矛盾。故选B。
