SIM Cards, Internet and VPNs in China: The 2026 Reality

Option 1 — International roaming / travel eSIM (easiest)

Global eSIMs (Airalo, Holafly) and your home carrier's roaming route traffic through overseas servers, so Google, WhatsApp and Instagram keep working without any setup. Costs run US$3–8/day. Downside: slightly slower speeds and higher latency; fine for maps and messaging, occasionally painful for video calls.

Option 2 — Chinese SIM without VPN

A China Mobile/Unicom/Telecom tourist SIM (passport required, sold at airport counters, ¥50–150 for 10–30 GB) gives fast domestic data but no access to Google/WhatsApp/Facebook. You can navigate with Amap, translate with Baidu, and message Chinese contacts with WeChat — the local way. Many 10-day travellers now do exactly this and report missing nothing.

Option 3 — Chinese SIM + VPN

If you must keep your usual apps, install a reputable paid VPN before you fly (download pages are themselves blocked inside China). Expect ¥25–50/month equivalent and occasional slowdowns; free VPNs are unreliable and a privacy risk.

Wi-Fi reality check

Hotel and café Wi-Fi is everywhere but also sits behind the national firewall — the same rules apply. Airport Wi-Fi needs a Chinese phone number to receive the login code, which is why the airport SIM counters stay busy. Download offline maps (Amap supports English, offline packs) before deep west-China trips where signal dies entirely.
