You said "that's where TMO evidently failed" and "it's fair to say the promo was not successful." Failure is defined as "lack of success" so if you say the promo was not a success then you're saying it was a failure.
TMO failed at comprehensively addressing Verizon's nationwide coverage. I don't agree with your binary classification either; "lack of success" doesn't necessarily have to mean failure. But I'll stop the semantics discussion
And if the point of the ad campaign was to combat potential losses from a competitor's ad campaign, then showing no significant loss during the time that the competitor's ad campaign ran would be the definition of success.
I would think the point was to poach more customers. Remember, TMO already had a positive porting ratio in the previous quarter, so there was no net loss of customers. But the porting ratio did drop the subsequent quarter when they specifically targeted Verizon--and that cannot be considered a success.
