What is Bulk SMS?
Bulk SMS is like sending the same message to thousands of people at once — directly to their mobile phones.
Instead of typing one message and sending it one by one, businesses use bulk SMS to:
Share offers and discounts
Send reminders and alerts
Deliver OTPs and transaction updates
Run awareness or promotional campaigns
It’s fast, affordable, and almost every SMS is read within minutes.
