Send SMS Using Python
Below are some ways and techniques to send SMS using Python:
- Twilio API Integration
- Vonage API Integration
Send SMS Using Twilio API Integration in Python
Below are some of the ways by which we use Twilio API integration to send SMS in Python:
Step 1: Create a Twilio Account
If you don't have an account, then sign up at Twilio.
Twilio sign up windowsStep 2: Get Twilio Credentials
After login you will receive your Account SID and Auth Token from its dashboard.
Step 3: Get a Twilio Phone Number
Get a Twilio phone number from the Twilio console. This will be the number by which your SMS will be sent.
Step 4: Install the Twilio Python Library
Install the Twilio Python library in your system using the following command in your terminal.
pip install twilio
Step 5: Write Python Code (send_sms.py)
Now you have to write this code and replacing directed credential with your Twilio credentials and contacts.
Python
from twilio.rest import Client
# in this part you have to replace account_sid
# auth_token, twilio_number, recipient_number with your actual credential
account_sid = 'account_sid'
auth_token = 'auth_token'
twilio_number = 'twilio_number'
recipient_number = 'recipient_number'
# Create Twilio client
client = Client(account_sid, auth_token)
# Send SMS
# in body part you have to write your message
message = client.messages.create(
body='This is a new message',
from_=twilio_number,
to=recipient_number
)
print(f"Message sent with SID: {message.sid}")
Step 6: Run the script
Now, save the above python script with extension .py and run it.
python file_name.py
After running successfully, you can check your console for the message SID, and you can verify your Twilio dashboard whether the SMS was sent successfully or not.

Send SMS in Python Using Vonage API Integration
Below are some of the ways by which we use Vonage API integration to send SMS in Python:
Step 1: Create a Vonage Account
If you don't have any account, then sign up at Vonage.
sign up windowStep 2: Get Vonage API Key and Secret
After login you will receive your Account SID and Auth Token from its dashboard.
Step 3: Install the Vonage Python Library
Install the Vonage Python library in your system.
pip install vonage
Step 4: Write Python Code (file.py)
Now you have to write this code and replacing directed credential with your Vonage credentials and contacts.
Python
import vonage
# Replace with your Vonage API key and secret
api_key = 'your_api_key'
api_secret = 'your_api_secret'
# Create a Vonage client
client = vonage.Client(key=api_key, secret=api_secret)
# Create a Vonage SMS client
sms = vonage.Sms(client)
# Replace with your phone number and the message you want to send
to_number = 'recipient_phone_number'
message = 'This is a message from vonage'
# Send SMS
response = sms.send_message({
'from': 'Vonage API',
'to': to_number,
'text': message
})
# Check the response
if response['messages'][0]['status'] == '0':
print(
f"SMS sent successfully to {to_number}. Message ID: {response['messages'][0]['message-id']}")
else:
print(
f"Failed to send SMS. Error: {response['messages'][0]['error-text']}")
Step 5: Run the Script
Now, save the above python script with extension .py and run it.
python file_name.py
After running successfully, you can check your console for the message SID, and you can verify your Twilio dashboard whether the SMS was sent successfully or not.
