Salesbot can be set up so that it first sends a message to the client on WhatsApp, and if the client's number does not have WhatsApp, Salesbot will send an SMS. Here's a schematic of such a process:

1. Select "Message" and enter a message.
2. Add the Interrupter "Until message received".
3. Add the Condition "If Client message Equals: Manual input" and enter the text "The client has not installed the application or has linked it to another number".

4. Add an SMS service widget when a condition triggers and enter the text of the message. If the Salesbot widget list doesn't include your SMS service, read the next section.
5. Add a bot stop.
6. Add a bot stop in the condition branch when the condition fails.
7. Click Save.
This is how the message from Salesbot will look in the deal card:

1. Create another stage in the funnel after the stage with Salesbot.

2. Click "Add Trigger" and search for the name of your SMS service.
3. Add a widget and enter the message.
4. Go to Salesbot settings and after "Condition" add "Action" → "Change lead status".

5. Select your stage with the SMS sending widget.
6. Add a bot stop.
7. Add a bot stop in the condition branch when the condition is not met.
8. Click "Save".
