Toll-free 800 numbers

When to call

Hong Kong has one time zone, Hong Kong Time (UTC+8). The cards below show your time and the time in Hong Kong.

Hong Kong does not change its clocks, so the time difference only shifts when your own country changes.

Call quality

A browser call needs a steady connection more than a fast one, using roughly half a megabyte to one megabyte of data per minute (an estimate).

• Use Wi-Fi or a good mobile signal.
• Use headphones to avoid echo.
• Switch off a VPN if the audio is choppy or one-way.
• Check the microphone permission if the other person can't hear you.
