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.
