中国旅游网络与上网指南 | Internet & Connectivity Guide for China Travel

网络限制 / Internet Restrictions

中国大陆屏蔽Google（含Gmail、Maps）、Facebook、Instagram、Twitter/X、WhatsApp、Telegram、YouTube、LINE等境外服务。替代方案：百度（搜索）、高德/百度地图（导航）、微信（即时通讯）、微博（社交）、哔哩哔哩（视频）。

Mainland China blocks Google (including Gmail, Maps), Facebook, Instagram, Twitter/X, WhatsApp, Telegram, YouTube, LINE, and other foreign services. Alternatives: Baidu (search), Amap/Baidu Maps (navigation), WeChat (messaging), Weibo (social media), Bilibili (video).

VPN选择 / VPN Options

出发前下载安装VPN（到了中国无法从应用商店下载）。稳定性较好的选择：ExpressVPN、NordVPN、Astrill。免费VPN基本不可用。VPN在中国属于灰色地带——外国游客使用不会被处罚，但连接稳定性取决于时期和地区。

Download and install a VPN before departing — you can't download them from app stores in China. Reliable options: ExpressVPN, NordVPN, Astrill. Free VPNs generally don't work. VPNs exist in a legal gray area in China — foreign tourists won't face penalties, but connection stability varies by period and region.

SIM卡与eSIM / SIM & eSIM

实体SIM：机场中国移动/联通/电信柜台购买，游客套餐约¥100–200含10–20GB流量。eSIM：Airalo、Holafly等平台提前购买，落地即用，无需排队。eSIM通常不含中国号码，无法注册微信支付等需要手机号的服务。

Physical SIM: Buy at China Mobile/Unicom/Telecom counters at the airport; tourist packages ~¥100–200 with 10–20GB data. eSIM: Buy from Airalo, Holafly, etc. before departure — works instantly on arrival, no queuing. eSIM usually doesn't include a Chinese phone number, so you can't register for services that require one (like WeChat Pay).

WiFi覆盖 / WiFi Availability

酒店、咖啡馆、机场、高铁站WiFi免费但速度参差。星巴克和麦当劳WiFi最稳定。高铁车上WiFi信号不稳定，隧道多的线路（如贵广高铁）会频繁断线。建议关键功能（地图、翻译）下载离线包。
