How to send bulk SMS in Sri Lanka
Steps
1. Create a VeloBotix account and register a Sender ID. 2. Export consenting contacts to CSV. 3. Remove landlines and duplicates. 4. Write a short message; check Unicode if you use Sinhala or Tamil. 5. Send a test to your own SIM. 6. Schedule or send. 7. Review delivery reports before the next blast.
Portal vs API
Use the portal for marketing teams. Use SEND_BULK_SAME or SEND_BULK_DIFFERENT when your CRM should fire the campaign.
FAQ
Do credits expire?
No. Buy when you need volume; unused credits stay on the account.
