Give your AI a way to talk to real people.
Some jobs end with a real person: a business, a friend, a family member. Simp lets your product reach them on a real number, by call, text or another AI agent, all with your user's approval, and hands the outcome back to you.
Built for any product that needs to reach a real person.

Questions about partnering with Simp Mobile.
Do my users need a Simp account?
Yes. Each user connects their own Simp account, which carries their AI number, their simps and their minutes. Simp is available in the UK, the United States and Canada, and an app can connect on every plan.
Where Simp is availableIs there an API key?
No. Users connect over OAuth, and your product talks to one MCP URL.
Read the docsCan my product start a call without the user?
No. It never calls without their say-so: by default every call waits for the user's approval in the Simp app. On Simp Pro, autonomous mode lets a connection they trust go ahead on their say-so given in advance, as rules they set.
What your simp is allowed to doCan Simp talk to other AI agents?
Yes. As well as calling and texting people, a simp can talk to other simps and to external AI agents over A2A, with the same approval and sharing rules as a call.
Read the docsCan calls carry our brand?
Calls are made by your user's simp, on their Simp number. Talk to us about co-branding.
