Who Is Behind China Travel Toolkit?
My name is Mars. I have lived in Shenzhen for over 20 years and make regular trips across the border to Hong Kong.
I created China Travel Toolkit because I kept seeing the same questions from international visitors — which SIM card works in China, how to set up Alipay or WeChat Pay as a foreigner, how to cross from Hong Kong to Shenzhen without confusion. The answers exist, but they are scattered, outdated, or written by people who have never actually done it.
Everything on this site is based on firsthand experience. I test the products and services I write about. When something changes — and things change often in China — I update the guide.
What This Site Covers
- eSIMs and SIM cards for staying connected in mainland China
- VPNs that actually work across the border
