Connect your account
Sign in with your registered Superfone phone number to complete the connection. No API key to copy.
Make sure the app is switched ON
Check that the Superfone connected app is toggled ON. If it is off, Gemini will tell you it can't make a phone call.
Say "via Superfone" when you ask for a call
Always include via Superfone in your request so the right tool is used. For example: "Call my dentist via Superfone and ask if they have a slot on Friday."
Without it, your assistant may try to answer without placing a call.
Connected apps are available on paid Gemini plans.
