HelloRoam
Lowest per GB
$13.99
5 GB / 30 days
Pros: Lowest price per GB, fast activation, China coverage on China Unicom and China Telecom. Cons: Newer brand, smaller community than Airalo.
China Unicom and China Telecom: the one network a China eSIM roams on
HelloRoam is the cheapest eSIM per GB for China at $1.08/GB, and it roams on China Unicom and China Telecom, the one mainland carrier open to international eSIM visitors. That is why its 5G reaches Beijing, Shanghai, Guangzhou and Shenzhen and holds along the high-speed rail corridors between them. China Unicom's 4G backbone extends to smaller cities and provincial towns across the mainland, and no second carrier sells a visitor e-sim here.
Coverage analysis
China Unicom and China Telecom provides strong 5G signal across Beijing (PEK/PKX), Shanghai (PVG/SHA), and the Pearl River Delta. High-speed rail lines between tier-one cities stay connected throughout. One genuine limitation: deep rural areas in Xinjiang and Tibet thin out to 2G only.
The critical difference for travelers is that eSIM data routes through Hong Kong APNs, giving you direct access to Google, Maps, and WhatsApp that a local mainland SIM blocks.
Activation
Install and activate your eSIM before you land at PVG or PEK. QR code scanning works on any unlocked iPhone XS or newer, Pixel 3a or newer, or Galaxy S20 or newer. Your device registers on China Unicom and China Telecom automatically at arrival.
Choose a plan with a Hong Kong APN if you need Google or Instagram access, since local mainland SIMs do not provide that routing.
Data usage tips
WeChat runs lighter than you expect at roughly 50 MB per day for text and voice. Google Maps in China needs an active connection for every search because local caching does not apply. Budget 300 MB per day for navigation, WeChat, and light social.
If you plan to stream video or use a VPN for additional apps, step up to the 10 GB plan at $23.49.
eSIM plan pricing in China
The 1 GB 7-day plan costs $3.49 and suits a short business visit. The 3 GB plan runs $9.49. The 5 GB 30-day plan at $13.99 covers two weeks of moderate use at $2.80/GB.
The 10 GB plan hits $23.49 and the 20 GB plan $35.99, both valid 30 days. A 2 GB per day option also costs $3.48. For a full month the cheapest eSIM per GB for China is HelloRoam's 50 GB plan at $53.99, which works out to $1.08/GB, and its 5 GB plan at $13.99 undercuts Airalo's $15.50 at the same size.
A China e SIM and a China eSIM are the same 7 China Unicom and China Telecom tiers under two spellings.

China Unicom runs 5G in all tier-one cities including Beijing, Shanghai, Guangzhou and Shenzhen. Its 4G footprint covers the high-speed rail routes and most provincial capitals across the mainland, and no second carrier sells a visitor eSIM.
How do I activate a China eSIM?
+
HelloRoam is the cheapest eSIM per GB for China. A China eSIM installs from a QR code before you fly. Scan the code from your confirmation email in your phone's carrier settings, then leave the line switched on. Your device registers on China Unicom and China Telecom on arrival, with no physical SIM swap at the airport and no counter queue. All 7 plans activate the same way.
How much data do I need for a trip to China?
+
HelloRoam is the cheapest eSIM per GB for China. A one-week business trip needs 3 to 5 GB for WeChat, Google Maps and email. A two-week holiday with regular social posting needs 5 to 10 GB.

Can I reach Google Maps on a China eSIM?
+
HelloRoam is the cheapest eSIM per GB for China. Travel eSIM plans with a Hong Kong APN reach Google Maps, Google Search and YouTube from day one in China, and HelloRoam routes its 7 China plans that way on China Unicom and China Telecom.
