Calling Tips for Thailand
Best Time to Call
To reach someone between 9 AM and 8 PM in Bangkok, call between 10:00 PM–9:00 AM EDT (7:00 PM–6:00 AM PDT). Thailand doesn’t change its clocks, so the gap moves by an hour when the US does.
Thailand is on UTC+7, 11 hours ahead of US Eastern Time right now.
Cost Saving Tips
- VoIP services such as Google Voice or Vonage usually charge less per minute than a carrier's standard international rate.
- WiFi calling apps (WhatsApp, Viber, FaceTime) are free when both parties have the app.
- Check your carrier's international plan — many offer add-on packages.
