Calling the USA from Thailand: A Comprehensive Guide

Calling friends, family, or conducting business in the United States from Thailand might seem daunting at first, but with a clear understanding of the process, it can be simple and affordable. This comprehensive guide will walk you through everything you need to know, from understanding international dialing codes to exploring various calling options and troubleshooting potential issues. Whether you’re a tourist, an expat, or a business professional, this article will provide you with all the necessary information to make successful calls from Thailand to the USA.

Understanding the Basics: Dialing Codes and Time Zones

Before you even think about making a call, it’s crucial to understand the basic building blocks: international dialing codes and time zone differences. These are fundamental for ensuring your call connects correctly and at an appropriate time.

International Exit Code for Thailand

The international exit code for Thailand is 001. This code tells the Thai telephone network that you are making an international call. You must dial this before any other codes when calling outside of Thailand. Think of it as unlocking the door to the international network.

United States Country Code

The country code for the United States is 1. This code identifies the destination country as the USA. This code follows the international exit code.

Area Codes in the USA

The US telephone system uses area codes to divide the country into different geographic regions. Every phone number in the US starts with a three-digit area code. You need to know the correct area code for the person or business you’re trying to call. Some common area codes include 212 (New York City), 310 (Los Angeles), 415 (San Francisco), and 713 (Houston). You can easily find the area code by searching online if you don’t already know it. Many websites provide area code lookup tools.

Putting it All Together: The Dialing Sequence

The complete dialing sequence from Thailand to the US is as follows:

001 (Thailand’s exit code)
1 (US country code)
[Area Code] (Three-digit area code of the US number)
[Local Number] (Seven-digit local phone number)

For example, to call a number in New York City (area code 212) with the local number 555-1234, you would dial: 001 1 212 555 1234.

Navigating Time Zone Differences

Thailand operates on Indochina Time (ICT), which is GMT+7. The United States has multiple time zones, including:

Eastern Time (ET): GMT-4 (GMT-5 during standard time)
Central Time (CT): GMT-5 (GMT-6 during standard time)
Mountain Time (MT): GMT-6 (GMT-7 during standard time)
Pacific Time (PT): GMT-7 (GMT-8 during standard time)

This means there’s a significant time difference. For example, when it’s noon in Thailand, it’s often late at night or very early morning in the US. Here’s a quick reference for the time differences:

Thailand is 11-14 hours ahead of the US, depending on the specific time zone and Daylight Saving Time (DST).
To calculate the time in the US, subtract 11-14 hours from the time in Thailand.

Always double-check the current time in both locations before making a call to avoid calling at inconvenient hours. Use online time zone converters for accurate calculations.

Calling Options: Choosing the Right Method for You

Several methods are available for calling the US from Thailand, each with its own advantages and disadvantages in terms of cost, convenience, and call quality.

1. Direct Dialing (Landline or Mobile)

How it works: This is the most straightforward method. You simply dial the full international dialing sequence (001 + 1 + Area Code + Local Number) from your Thai landline or mobile phone.

Pros:

Simple and direct.
No need for special apps or software.
Reliable call quality (generally).

Cons:

Can be the most expensive option, especially for long calls.
Call rates vary depending on your Thai phone service provider.

Tips:

Check your phone service provider’s international calling rates before making a call.
Consider purchasing an international calling package from your provider for lower rates.

2. Voice over Internet Protocol (VoIP) Services

VoIP services use the internet to transmit voice calls, making them a significantly cheaper alternative to direct dialing.

Popular VoIP Services:

Skype: A widely used platform for voice and video calls. Skype offers both free calls to other Skype users and paid calls to landlines and mobile phones.
Google Voice: Allows you to make calls over the internet using your Google account. Google Voice offers very competitive international calling rates.
WhatsApp: Primarily a messaging app, but also supports voice and video calls. Calls to other WhatsApp users are free, regardless of location.
Viber: Similar to WhatsApp, Viber offers free calls and messages to other Viber users, as well as paid calls to landlines and mobile phones.
Other VoIP Apps: Numerous other VoIP apps are available, such as Line, Telegram, and Facebook Messenger, each offering similar features and varying international calling rates.

How it Works:

Download and install the VoIP app of your choice on your smartphone, tablet, or computer.
Create an account and add funds if necessary (for calls to landlines and mobile phones).
Dial the US number using the app’s dialer.

Pros:

Significantly cheaper than direct dialing.
Often offers better call quality than traditional phone lines, especially with a good internet connection.
Many VoIP services offer additional features like video calling, messaging, and screen sharing.

Tips:

Test your internet connection speed before making a call to ensure good call quality.
Use a Wi-Fi connection whenever possible to avoid using your mobile data.
Compare the international calling rates of different VoIP services to find the best deal.

3. Calling Cards

Calling cards offer a prepaid way to make international calls. You purchase a card with a specific amount of credit and then use it to make calls at a discounted rate.

How it works:

Purchase a calling card from a convenience store, supermarket, or online retailer in Thailand.
Scratch off the PIN code on the back of the card.
Dial the access number provided on the card.
Enter the PIN code when prompted.
Dial the US number (001 + 1 + Area Code + Local Number).

Pros:

Can be cheaper than direct dialing, especially for short calls.
No need for an internet connection.
Good for those who don’t have access to VoIP services or prefer not to use them.

Cons:

Call quality can be inconsistent.
May have hidden fees or connection charges.
The credit on the card can expire.

Tips:

Read the terms and conditions of the calling card carefully before purchasing it.
Look for cards with no connection fees or hidden charges.
Use the credit on the card before it expires.

4. Mobile Apps with International Calling Features

Some mobile apps, beyond traditional VoIP services, offer integrated international calling features. These often combine messaging, calling, and other functionalities into a single platform.

Examples:

Rebtel: Offers local phone numbers in both Thailand and the US, allowing you to make calls over local lines instead of relying solely on internet connections. This can result in better call quality and lower costs.
Dingtone: Provides free calls and texts to other Dingtone users, as well as cheap international calls to landlines and mobile phones. You can earn credits by completing tasks within the app, which can then be used to make calls.

Pros:

Often combines multiple communication features into one app.
Can offer better call quality and lower costs than traditional VoIP services.
May provide features like call recording, call forwarding, and voicemail.

Cons:

Requires downloading and installing a specific app.
May require creating an account and providing personal information.
Call quality can still be affected by internet connection.

Tips:

Explore different mobile apps with international calling features to find one that meets your needs and budget.
Read reviews and compare features before downloading an app.
Check the app’s privacy policy to ensure your data is protected.

Optimizing Call Quality: Tips for a Clear Connection

No matter which calling method you choose, several factors can affect call quality. Here are some tips to optimize your connection and ensure a clear conversation:

1. Stable Internet Connection

If you’re using a VoIP service or mobile app, a stable and fast internet connection is crucial. A weak or intermittent connection can lead to dropped calls, choppy audio, and delays. Ideally, use a Wi-Fi connection instead of your mobile data, as Wi-Fi is generally more reliable and faster.

2. Minimize Background Noise

Background noise can make it difficult for the person on the other end to hear you clearly. Try to make calls from a quiet environment, away from traffic, crowds, or other distractions. If you’re in a noisy area, consider using a headset with a noise-canceling microphone.

3. Use a Headset or Headphones

Using a headset or headphones can significantly improve call quality by reducing echo and feedback. It also allows you to speak more clearly and comfortably, without having to hold your phone to your ear.

4. Close Unnecessary Apps

Running multiple apps simultaneously can slow down your device and affect internet connection speed. Close any unnecessary apps before making a call to free up resources and improve performance.

5. Update Your Software

Make sure your operating system and VoIP app are up to date. Software updates often include bug fixes and performance improvements that can enhance call quality.

6. Check Microphone and Speaker Settings

Ensure that your microphone and speaker are properly configured and working correctly. Adjust the volume levels to ensure you can hear and be heard clearly.

7. Consider the Time of Day

Internet traffic can be heavier during peak hours, which can affect call quality. Try making calls during off-peak hours when the network is less congested.

Even with the best preparation, you might encounter some issues when calling the US from Thailand. Here’s how to troubleshoot some common problems:

1. Call Not Connecting

Possible Causes:

Incorrect dialing sequence.
Blocked international calls.

Contact your Thai phone service provider to ensure international calls are enabled.
Try calling again later to rule out network issues.

2. Poor Call Quality

Possible Causes:

Weak internet connection.
Background noise.
Outdated software.

Solutions:

Move to a location with a stronger internet connection.
Minimize background noise.
Update your software.
Use a headset or headphones.

3. Echo or Feedback

Possible Causes:

Speakerphone is too loud.
Microphone is too close to the speaker.

Solutions:

Lower the speaker volume.
Use a headset or headphones.
Move the microphone further away from the speaker.

4. Dropped Calls

Ensure your device is fully charged or plugged in.

Saving Money on International Calls

Calling the US from Thailand doesn’t have to break the bank. Here are some tips for saving money on international calls:

1. Compare Calling Rates

Before making a call, compare the international calling rates of different phone service providers, VoIP services, and calling cards. Rates can vary significantly, so it’s worth doing some research to find the best deal.

2. Use VoIP Services for Long Calls

VoIP services are generally much cheaper than direct dialing, especially for long calls. Consider using Skype, Google Voice, or another VoIP app for extended conversations.

3. Take Advantage of Free Calls

Many VoIP services and mobile apps offer free calls to other users of the same platform. If you’re calling someone who also uses the same app, take advantage of this free option.

4. Purchase an International Calling Package

Your Thai phone service provider may offer international calling packages that provide discounted rates for calls to the US. Check with your provider to see if they have any suitable packages available.

5. Call During Off-Peak Hours

Some phone service providers offer lower rates for calls made during off-peak hours. Check with your provider to see if they have any discounted calling times.

6. Use a Callback Service

Callback services allow you to make international calls by having the service call you back and connect you to the desired number. This can be a cheaper option than direct dialing, as you’re only paying for the inbound call.

7. Consider a Local SIM Card

If you’re planning to make a lot of international calls from Thailand, consider purchasing a local SIM card with a favorable international calling plan. This can be a more cost-effective option than using your regular SIM card.

Staying Connected: Alternatives to Phone Calls

While phone calls are a classic way to stay connected, several other communication methods are available, each with its own advantages.

1. Messaging Apps

Apps like WhatsApp, Line, WeChat, and Facebook Messenger allow you to send text messages, photos, videos, and voice notes for free, as long as you have an internet connection. This is a great way to stay in touch with friends and family without incurring any calling charges.

2. Video Calls

Video calls offer a more personal way to connect with loved ones. Apps like Skype, Google Meet, Zoom, and FaceTime allow you to see and hear the person you’re talking to, making it feel like you’re in the same room.

3. Email

Email is a reliable way to send longer messages and documents. While it’s not as immediate as a phone call or text message, it’s a good option for non-urgent communication.

4. Social Media

Social media platforms like Facebook, Instagram, and Twitter allow you to share updates, photos, and videos with your friends and family. This is a great way to stay connected and see what’s happening in their lives.

5. Letters and Postcards

In the age of digital communication, receiving a handwritten letter or postcard can be a special treat. Consider sending a traditional letter or postcard to show your loved ones you’re thinking of them.

Calling the USA from Thailand is easier than ever with the variety of options available. By understanding the dialing codes, time zone differences, and various calling methods, you can choose the most cost-effective and convenient option for your needs.
