Mobile Phone Networks
Hong Kong mobile numbers are typically 8 digits long and commonly start with 5, 6, or 9. Mobile number portability is widely available, meaning the starting digit doesn't always indicate the current network provider.
| Major Network Providers | Common Starting Digits |
|---|---|
| HKT (PCCW-HKT) | 5, 6, 7, 8, 9 (Portability common) |
| SmarTone | |
| 3 Hong Kong (Hutchison) | |
| China Mobile Hong Kong (CMHK) |
Remember to dial 011 + 852 + Full 8-digit Mobile Number regardless of the network.
Time Difference
Hong Kong operates on Hong Kong Time (HKT), which is UTC+8 year-round. Hong Kong does not observe Daylight Saving Time.
This means the time difference with the US varies:
Eastern Time (ET): 12 hours ahead of ET (UTC-5). 13 hours ahead during US Daylight Saving Time (UTC-4).
Central Time (CT): 13 hours ahead of CT (UTC-6). 14 hours ahead during US Daylight Saving Time (UTC-5).
Mountain Time (MT): 14 hours ahead of MT (UTC-7). 15 hours ahead during US Daylight Saving Time (UTC-6).
Pacific Time (PT): 15 hours ahead of PT (UTC-8). 16 hours ahead during US Daylight Saving Time (UTC-7).
Check the current time difference before calling, especially when the US is observing Daylight Saving Time (roughly March to November).
Hong Kong's Phone System
Hong Kong boasts a highly advanced and reliable telecommunications infrastructure. Mobile phone penetration is extremely high, with widespread 4G and 5G coverage. Landline services are also excellent and widely available. Internet-based communication apps like WhatsApp are very popular for personal calls, but traditional phone calls remain common for business and reaching landlines.
Best Times to Call
Considering the significant time difference, coordinating calls between the US and Hong Kong requires planning.
Typical Hong Kong business hours are Monday to Friday, 9:00 AM to 6:00 PM HKT. Lunch breaks are common around 1 PM.
The best overlap for calls often occurs during US evening hours. Aim for 7 PM to 11 PM ET / 4 PM to 8 PM PT, which corresponds to 7 AM to 11 AM HKT / 8 AM to 12 PM HKT the next day. Always confirm the current time difference, especially during US Daylight Saving Time.
