Privacy and payment checks
Review the permissions requested by each app and avoid installing unfamiliar packages from links or QR codes. Do not assume a Hong Kong account or wallet will work for every mainland service. Confirm eligibility, fees and current terms with the provider.
See the northbound payment guide and Shenzhen port comparison.

Frequently asked questions
Can I use my Hong Kong phone number to register?
It depends on the app. Check its current registration and verification rules before departure; some services may require a mainland number or additional identity checks.
Will a Hong Kong mobile wallet work for every payment?
No. Acceptance depends on the merchant, wallet, account verification and linked payment method. Carry a backup payment option.
Should I install apps after reaching Shenzhen?
Set up and test essential services before travelling where possible. Use official app stores and verify the publisher.
