You will need:

Once approved, your brand name becomes officially registered.
Step 2: Sender ID Approval
Sender IDs identify your car rental brand in every SMS.
Examples:
- XYZCAR

Sender IDs typically get approved within 24 to 48 hours.
Step 3: SMS Template Registration
Each SMS type must be pre-approved.
Examples include:
- Booking confirmation
- OTP verification
- Driver details
- Trip reminders
Templates are submitted with fixed text and approved variables such as booking ID or OTP.

Step 5: SMS Activation and Testing
