Validation is only performed when an SMS is queued before sending, not during Contact Import/Creation. If the number is identified as a landline number, we will not send even the first message to the carriers.
Validation only needs to be activated in Topline OS to function.
We can Filter Based on the Error when the Phone Number is
- Not valid
- SMS incapable
