I’m not able to analyze “what would happen if…” scenarios for individual cases. I don’t have access to the logic table for the system. However, we are confident that if you follow the exact steps I provided, the system will recommend phones optimized for the best coverage for that purchase.
I analyzed the what-if scenario myself by logging into my granddaughter’s account and taking an order all the way to the last step. Along the way I changed the shipping address to her address in the ZIP described as having no cell coverage and, unless something happens on the very last click that places the order, the system will sell a phone to that address.
This raises more questions: Does the algorithm use the billing address or the shipping address? How can it select a phone in a zip it thinks has no coverage at all?
