2. WeChat — For Mainland China Connections
WeChat is essential if your Hong Kong contact has ties to mainland China. Many Hong Kong residents use both WhatsApp and WeChat — WhatsApp for local contacts, WeChat for cross-border communication with the mainland. WeChat voice and video calls are free.
Tip: If your contact works in finance, trade, or any China-facing business, they almost certainly have WeChat. Ask which app they prefer.
