Greater Bay Area travel eSIM comparison
GBA plans are built for the weekly Shenzhen/Guangzhou/Macau crossing: one SIM whose data pool spans Hong Kong, Macau and mainland cities, often with daily CN allowances. Because they're HK-issued, your apps bypass the firewall on the mainland leg.

FAQs
Do GBA plans work immediately at Lo Wu / West Kowloon?
Yes — they register on China Mobile/Unicom partner networks automatically within a minute of crossing. Keep data roaming enabled; the switch happens in the background.
GBA plan vs a dedicated China data add-on — which?
Frequent crossers: GBA plans win on convenience and shared pools. Occasional visitors: a short China add-on on your existing plan can be cheaper — compare both tables on this page against our China guide.
