## What is RoamChina?

Landing in China and not sure whether your phone will work the way it does at home? RoamChina turns that uncertainty into a short plan: pick the data setup that fits your trip, then check the connection you actually get once you arrive. Free, offline-ready, and no account needed.

BEFORE YOU FLY: GET A PLAN THAT FITS YOUR TRIP
• Tell RoamChina how long you are staying, how many people are travelling, and how much data you use
• Get a matched combination of travel eSIM or roaming plus hotel Wi-Fi, with a reference cost for the whole trip
• Compare travel eSIMs, managed subscriptions, a personal server, and your existing roaming side by side
• See which option needs the fewest setup steps and where each one falls short

AFTER YOU LAND: CHECK THE CONNECTION YOU HAVE
• One tap tests reachability for the local and international services travellers rely on
• See your network exit, latency, and download speed on Wi-Fi and on mobile data
• Detect hotel Wi-Fi sign-in pages and other common connection problems
• Optional location context tells you whether the result is a pre-trip or in-China reading
• Share a diagnosis card as an image when you need help from a friend or your provider

ON THE ROAD: EVERYTHING WORKS WITHOUT A CONNECTION
• Step-by-step setup checklists you can follow at the airport or in a hotel lobby
• Field guides on eSIMs, hotel Wi-Fi, roaming, and how two networks can behave differently
• An interactive Connection Lab that shows why the same app can work on cellular but not on hotel Wi-Fi
• A Home Screen widget with your next step and a bookmark list for the guides you want at hand
• Trip choices and checklist progress stay on your iPhone

BUILT FOR TRAVELLERS, NOT ENGINEERS
• Plain language in English, Simplified Chinese, and Traditional Chinese
• Dark Mode, Dynamic Type, and VoiceOver supported
• No ads, no tracking SDKs, no sign-up

WHAT ROAMCHINA IS NOT
RoamChina is a planning and diagnosis tool. It does not provide a VPN or proxy service, does not create a network tunnel, and does not change your iPhone's network settings. A successful endpoint check shows that a service responded; it does not guarantee that sign-in, payments, calls, or every feature will work. Third-party prices, availability, and terms change; confirm them with the provider before you buy.

Some provider links include disclosed affiliate parameters. If you buy on an independent third-party site, we may earn a small commission. This does not change the recommendation order and does not unlock anything in RoamChina.
