Keep the order simple
The site intentionally avoids asking buyers to commit to channels during checkout. That works in favor of WhatsApp-oriented users because they can receive the device, complete first boot, and then decide exactly how they want the workflow configured.
Why this is cleaner than DIY
When WhatsApp is just one layer on top of a prepared device, the buyer avoids mixing base system setup with day-one messaging configuration. That separation lowers friction.
Where the value comes from
The value is not that WhatsApp exists. The value is that the phone arrives with the hard setup already handled, so adding a WhatsApp workflow later feels like a final connection step instead of an entire project.
