eSIM for China and Hong Kong: Plans That Cover Both

Which providers sell one plan

Provider	Plan	Covers	Cheapest plan	Routing in mainland China
Holafly	Hong Kong, Macau and China	Those three only	Unlimited, 1 day, €3.90 (no US dollar price shown)	Not stated on the plan page
Nomad	Greater China	Mainland China, Hong Kong, Macao, Taiwan	1 GB, 7 days, $5.00	Not stated on the plan page
Airalo	Asia	18 countries, including mainland China, Hong Kong and Macao	1 GB, 3 days, $4.00	Outside mainland China, Airalo says
Saily	Asia and Oceania	22 countries, including China, Hong Kong and Macau	1 GB, 7 days, $4.99	No claim found

Holafly’s and Saily’s China-only plans won’t cover the trip. Holafly says its China eSIM “is designed for use in mainland China only” and that you need a separate eSIM for Hong Kong or Taiwan. Saily says its China plan won’t work in Hong Kong or Macau, because both are special administrative regions.

The China-only plans are covered on our Airalo, Holafly, Nomad and Saily pages. Airalo vs Holafly for China compares two of them.

Routing in mainland China

On the mainland, blocked apps such as WhatsApp and Google work on an eSIM only if the plan sends your data outside mainland China first. eSIM or VPN for China? explains how this works. Here is what each provider says about these plans:

• Airalo: a VPN is “NOT required” on its “China eSIM, Regional Asia eSIM, and Global eSIM”. Airalo says “your traffic is routed through secure gateways outside mainland China”.
• Holafly: the page for this plan doesn’t describe routing or name a network. It says you can call and message through apps such as WhatsApp. Holafly’s routing FAQ says it uses “home-routed roaming” through “international gateways”, but doesn’t say which eSIMs this covers. Its China-only eSIM page says WhatsApp, Google and Instagram work “without installing an additional VPN”.
• Nomad: the Greater China page doesn’t say. A Nomad blog post on Hong Kong and Macau says its regional Asia plans also cover China, and that you wouldn’t need a separate VPN in Shenzhen. It doesn’t name the Greater China plan.
• Saily: we found no routing claim for the Asia and Oceania plan. Saily’s China page says you need a VPN for WhatsApp in China. Our Saily page covers its conflicting claims about the China plan.

This only applies to the eSIM’s mobile data. Airalo says you get full access to blocked sites “as long as you are using your eSIM data (and not the hotel Wi-Fi)”. For Wi-Fi, see VPN for hotel Wi-Fi in China.
