Spectrum撸的手机不能给其他卡启用WiFi calling？
S25+在US Mobile Warp网络下WiFi Calling选项消失，疑似Verizon固件兼容问题。

最新动态
Spectrum撸的S25+解锁了，加上了US Mobile的eSIM，居然打不开WiFi calling，是整个选项消失的那种。客服研究了一个小时，这么回复我的： Alright, so I checked with my team and it seems that this issue do comes with Samsung devices on the Warp network. What we can do now to activate wifi calling is that we can transfer you to Dark Star or Light speed network. Thanks for your patience! Since Wi-Fi Calling has been inconsistent and currently isn’t even showing in your settings, and given that we’ve already escalated this with our parent carrier, it looks like the best path forward at this point is to transfer your line to our other network . This should help restore full functionality, including Wi-Fi Calling. Let me know if you’d like me to go ahead and start that process for you. Unfortunately, there’s a firmware issue with certain Samsung phones from the manufacturer’s end, causing the Wi-Fi calling feature to not appear in the settings. Regrettably, this is beyond our control. 这事得刷机才能破了？我记得以前Google Fi撸的S22也有个怪毛病，就是visual voicemail打不开，后来自己好了，但WiFi calling我还挺刚需的
直接刷官方版，网上有教程
我s25ultra，没刷固件，解锁后esim用的att和helium，都能开wifi calling
那估计就是Verizon的问题了
楼主最后怎么样了？我S26 PLUS今天换到US MOBILE WRAP下面，也发现没有wifi calling选项。
