Frequently asked questions

How fast can I start sending SMS?

Create an account, top up a bundle, and send your first message via the API or dashboard in minutes.

Do you support delivery reports?

Yes, every message returns a delivery receipt with per-recipient status you can track in the dashboard or via webhooks.

Can I use a custom sender ID?

Yes. Register an alphanumeric sender ID (e.g. your brand name) or use a numeric long/short code, subject to local carrier regulations.

What throughput can I achieve?

Throughput scales with your plan and route. High-volume senders can connect directly over SMPP for sustained, low-latency delivery.

Do you support two-way SMS?

Yes, inbound messages and replies are delivered to your systems in real time via webhooks, so you can build keywords, opt-outs, and conversations.

Which networks are covered?

All major Zambian mobile networks (MTN, Airtel, Zamtel, and Zedmobile) through direct carrier routes with smart routing and automatic failover for reliability.
