How to send SMS from WhatsApp to WhatsApp - in detail?

To send an SMS from WhatsApp to another WhatsApp user, you'll need to follow a specific process since WhatsApp itself doesn't support direct SMS sending within the app. However, there are workarounds that can help you achieve this. Here’s a detailed guide on how to do it:

Using Third-Party Services

1. Choose a Reliable Service: There are several third-party services available online that allow you to send SMS messages. Some popular options include Twilio, Nexmo (Vonage), and Clickatell.
2. Create an Account: Sign up for the service of your choice. Most services will require you to provide some basic information and a valid phone number for verification purposes.
3. Purchase Credits: You’ll need to buy credits or subscribe to a plan that suits your needs. The cost per SMS can vary depending on the service and the destination country.
4. Integrate with WhatsApp: Unfortunately, these services don't directly integrate with WhatsApp. However, you can use their APIs to send SMS messages from a web-based interface or a custom application that you create.

Using an Android Device

If you’re using an Android device, there are apps available in the Google Play Store that allow you to send SMS messages directly from WhatsApp:

1. Download and Install: Search for an app like "SMS through WhatsApp" or similar in the Google Play Store and install it on your device.
2. Grant Permissions: Make sure to grant the necessary permissions for the app to access your contacts and send SMS messages.
3. Send Message: Open WhatsApp, select the contact you want to send an SMS to, and use the app’s functionality to send the message as an SMS.

Using Web-Based Services with Scripts

For more tech-savvy users, you can use web-based services combined with scripts to automate the process:

1. Choose a Web Service: Select a web service like Twilio that provides an API for sending SMS messages.
2. Set Up API Credentials: Obtain your API credentials (Account SID, Auth Token) from the service provider’s dashboard.

3. Write a Script: Use a programming language of your choice (Python is commonly used) to write a script that sends an SMS message using the service's API. Here’s a basic example in Python:

   from twilio.rest import Client
   # Your Account SID and Auth Token from twilio.com/console
   account_sid = 'your_account_sid'
   auth_token = 'your_auth_token'
   client = Client(account_sid, auth_token)
   message = client.messages.create(
    body="Hello from WhatsApp via SMS!",
    from_='+1234567890', # Your Twilio phone number
    to='+0987654321' # The recipient's phone number
   )
   print(message.sid)

4. Run the Script: Execute your script whenever you need to send an SMS message. This method provides a high degree of automation and flexibility.

Conclusion

While WhatsApp doesn’t natively support sending SMS messages, using third-party services, Android apps, or custom scripts can help bridge this gap effectively. By following the steps outlined above, you can send SMS messages from WhatsApp to another WhatsApp user with ease.
