Credits are calculated exactly like regular SMS – based on actual messages sent.
Basic Calculation:
Total Credits = Number of Recipients × SMS Parts × RateSMS Parts Depend On:
Standard Text (160 chars/SMS):
- 1-160 characters = 1 SMS
- 161-320 characters = 2 SMS
- 321-480 characters = 3 SMS
Unicode Text (70 chars/SMS):
- 1-70 characters = 1 SMS
- 71-140 characters = 2 SMS
- 141-210 characters = 3 SMS
Examples:
Example 1: Simple Text Message
- Recipients: 100
- Message: “Hi {{NAME}}, this is your reminder.” (36 characters)
- SMS Parts: 1
- Rate: ₹0.25 per SMS
- Total Cost: 100 × 1 × ₹0.25 = ₹25
Example 2: Long Unicode Message
- Recipients: 500
- Message: Hindi text (150 characters)
- SMS Parts: 3 (Unicode)
- Rate: ₹0.30 per SMS
- Total Cost: 500 × 3 × ₹0.30 = ₹450
Example 3: Multiple Groups with Duplicates
- Group A: 200 contacts
- Group B: 150 contacts
- Duplicates: 50 contacts
- Unique Recipients: 300 (200 + 150 – 50)
- Message: 1 SMS part
- Rate: ₹0.25 per SMS
- Total Cost: 300 × 1 × ₹0.25 = ₹75
