iPhone SE back orders and promotion

Hello,

I am considering moving myself and my family over to Xfinity Mobile. I am trying to get the $200 iPhone SE promotion, but am unsure if the backorder dates will affect this. As the terms are currently written, I would have 30 days from purchase date to activate my number on the new phone in order to take advantage of the promotion. 

The problem I am facing is that the backorder dates have continued to move further and further back. If the phone is purchased before the promotion date ends (5/17/20), will the 30 days be waived and the promotion still be honored even if the phone cannot be activated within those 30 days? 

Thanks.
