eSIM, roaming, or a local SIM—what should I use?
Choose by device support, trip length, data needs, and whether you need a mainland number. For short trips, many visitors prefer an offshore or Hong Kong–routed travel eSIM bought before departure—some plans make Google, WhatsApp, and similar apps easier than a mainland carrier alone. Roaming can work with less setup; a local SIM helps when services prefer a China number. Confirm activation, hotspot rules, and app behavior with the provider before you fly.
Will Google, WhatsApp, Instagram, or Google Maps work?
On many mainland networks, Google services, WhatsApp, Instagram, and Google Maps can be blocked or unreliable. An offshore or Hong Kong–routed travel eSIM is the cleanest fix for most short trips so those apps keep working without juggling a separate VPN. Still install Amap (Gaode) as the local navigation backup for metro exits, walking routes, and Chinese place names, and download hotel and ticket details offline before you fly.
Which apps should I download before traveling to China?
Start with the tools that remove first-day friction: Alipay or WeChat for payments, DiDi or an in-wallet ride service, 12306 for trains, and a map and translation option that you have tested. Finish account verification before departure, keep your home number active for security codes, and save hotel and ticket details offline.
