WiFi calling fails on iPhones despite carrier support claims

Similar Problems
surfaced semanticallyT-Mobile Customers Pay for Service They Can Only Access Via WiFi or Hotspot
T-Mobile customers in coverage-deficient areas pay full mobile service rates but have no usable cellular signal at home or in common locations, requiring reliance on WiFi or other hotspots to function. The billing continues at the contracted rate despite the service being non-functional. This gap between contracted service and delivered coverage is a structural consumer harm with no self-service remedy.
Mobile subscribers pay full plan rates but have zero usable signal outside home Wi-Fi
Subscribers on major carriers like T-Mobile pay $40–$80/month for cellular plans yet rely entirely on home Wi-Fi or employer hotspots to place calls and access data. Coverage maps overstate usable signal density, and support teams have no remedy beyond suggesting the customer use what they already have. The subscriber has no leverage to exit contracts or receive credits without extensive escalation.
T-Mobile WiFi calling fails internationally and SMS verification blocks account access abroad
T-Mobile WiFi calling fails silently when abroad with no workaround, and the carrier requires SMS verification to access accounts—a code that cannot be received on an international number. Users are locked out of support at the moment they need it most.
T-Mobile and Apple Both Refuse to Replace Defective Phone Sold Through Carrier
A customer received a defective T-Mobile phone that failed to receive emergency calls from day one, but T-Mobile refused replacement and deferred to Apple, who refused because the 14-day return window had passed. The handoff between carrier and manufacturer creates an accountability gap that leaves customers with a non-functional device and no recourse. This gap is especially dangerous when emergency call failures are involved.
Telecom carrier acquisition leaves customers with no service during transition
When T-Mobile acquired a smaller carrier, the transition left a customer with no service from day one, with no device delivery and inability to call support. This is a carrier-managed transition failure with no external software remedy.
