如何在海外使用 eSIM 上 WhatsApp

WhatsApp 与旅行 eSIM 完美配合

WhatsApp 是旅行者最常用的即时通讯应用，可通过 eSIM 数据连接无缝使用。语音通话、视频通话、发送消息和分享媒体文件，一切都和在国内一样顺畅。

WhatsApp 支持 eSIM 吗？

支持。WhatsApp 的所有功能均通过网络连接实现，而非手机号的蜂窝服务。只要有数据（来自您的 eSIM），WhatsApp 就能正常使用。

设置——无需任何操作

即使您使用其他 SIM 卡上网，WhatsApp 仍会继续绑定您的原始手机号。您无需更改 WhatsApp 中的任何设置。

保持原有 SIM 卡处于激活状态以保留手机号

WhatsApp 流量消耗

语音消息：每分钟约 5–10 MB

海外使用 WhatsApp 的省流技巧

关闭媒体自动下载以节省流量：WhatsApp → 设置 → 存储和数据 → 媒体自动下载 → 设为仅 WiFi
用语音通话代替视频通话以减少流量消耗
以较低画质发送图片：WhatsApp → 设置 → 存储和数据 → 媒体上传质量 → 省流模式
