Everything you need. Nothing you don't.

Delivery-only

We send OTPs, you verify them. No stored phone numbers, no lock-in. One endpoint, that's it.

Credit-based, no subscriptions

Buy credits, spend them as you go. Test mode fires zero real SMS and deducts zero credits — identical response shape.

Built for Malaysia

PDPA-compliant from day one. Phone numbers never stored in full. Delivery logs auto-purged after 90 days.

Simple, transparent pricing

Pay only for what you send. No subscriptions, no surprises.
