Trying to connect my Twilio Phone number to the send_text_tool but I get “No configured Twilio numbers found. Add one in Phone Numbers.” I’ve refreshed the page but it does not find the phone number in the Settings section in the send_text_tool page.

Import your Twilio number via the Phone Numbers section using your Twilio credentials, ensure it’s SMS-enabled, then assign it to the send_text_tool in the Tools settings.

It’s a UK mobile number - so I’m not entirely sure…

You can use your UK Twilio number with Vapi’s send_text_tool if it’s SMS-enabled, properly imported via the Phone Numbers section, and assigned in the Tools settings, just ensure it complies with UK SMS regulations.

Were you able to configure the SMS properly?

checking if this is resolved/solved for you?

Yes the text works but is there a potential way to transition the whole convo via chat over text?

You can transition a conversation from voice to text by using call transfers and integrating with messaging platforms via workflows and server URL setups.
