苹果 iPhone 18 Pro/Max 仅限 eSIM 地区共 12 个，与上代保持一致

苹果 iPhone 18 Pro 和 iPhone 18 Pro Max 在巴林、加拿大、关岛、日本、科威特、墨西哥、阿曼、卡塔尔、沙特阿拉伯、阿联酋、美国、美属维尔京群岛等 12 个国家和地区采用仅 eSIM 设计，不再配置物理 SIM 卡槽1。该受限地区名单与上代 iPhone 17 Pro 系列保持完全一致1。

这一设计调整为内部腾出空间以容纳更大容量电池1。iPhone 18 Pro Max 的电池容量相比前代升至 5567mAh（国行版本为 5391mAh），而上代 iPhone 17 Pro Max 为 5088mAh1。同时，iPhone 18 Pro 系列的充电功率也有所提升，达到 3560W，相较 iPhone 17 Pro 系列约 3040W 的功率范围有所增强1。苹果自 2022 年 iPhone 14 系列起在美国推行仅 eSIM 设计1。

Apple's iPhone 18 Pro and iPhone 18 Pro Max will feature eSIM-only designs in twelve specific countries and territories, with no physical SIM card slots 1. The list of eSIM-only markets—Bahrain, Canada, Guam, Japan, Kuwait, Mexico, Oman, Qatar, Saudi Arabia, the United Arab Emirates, the United States, and the U.S. Virgin Islands—remains unchanged from the iPhone 17 Pro lineup 1.

By eliminating the physical SIM slot, Apple has freed internal space to accommodate larger batteries 1. The iPhone 18 Pro Max will include a 5,567 mAh battery (5,391 mAh for the mainland China variant), representing an increase from the previous generation's 5,088 mAh capacity 1. Charging capabilities have also been enhanced, with the iPhone 18 Pro series reaching 35–60W, compared to approximately 30–40W for the iPhone 17 Pro models 1. Apple first introduced eSIM-only design for the iPhone 14 series in the United States in 2022 1.
