Original Summary

I switched from Verizon to T-Mobile, specifically because there were too many silent missed calls. Silent meaning my device never showed I had a missed call.<p>This was a pattern across more than a year, spanning multiple devices (all iphones). It happens on both wifi and cellular. It happens with wifi calling enabled and disabled. It happens with people I call every day, in my address book, as well as new contacts (say someone I met who called to follow up). I called support, searched online, reset network settings multiple times at different points months apart.<p>After being on T-Mobile for about a year, the degraded service is about the same as Verizon. Every week, more than once, people call me, my phone never rings, and I never see a missed call on my device. It happens at home, at work, on work trips in different states.<p>I still get missed calls regularly and my device shows I missed the call. It seems like a certain % of callers get my VM, but I never know the call attempt happened. The missed calls never appear later on my phone (like a late VM or text deliver, coming minutes or sometimes hours after it was sent).<p>Hypothesis: A growing number of cellular subscribers don&#x27;t care enough or use voice calls as much, so (regardless of motive&#x2F;feelings) cellular providers have found they can simply reduce quality without losing customers.

用户反映从 Verizon 换到 T-Mobile 后，仍常出现手机不响、也无漏接记录的来电，跨多台 iPhone、Wi-Fi 与蜂窝、开关 Wi-Fi 通话均如此；由此提出假设：因越来越多用户不重视语音通话，运营商可降低质量而不流失客户。
