iPhone: Settings › Mobile Data › Wi-Fi Calling. Android: Settings › Connections or Network › Wi-Fi Calling (wording varies by manufacturer).

Persistent, material failure of coverage represented at signup constitutes grounds for formal complaint: dated evidence assembled — checker captures and failed-call logs across weeks — the matter raised in writing, and the eight-week or deadlock route pursued per the consumer rights guide. Where a service materially fails, a written request for penalty-free departure is a reasonable remedy to seek.
