Tell me more about this FWIW. If that could solve the coverage problem we might be able to keep most of us on TMobile (which is cheaper) and leave daughter on Verizon for $50/month (and call it a cost of going to college there).
How'd we end up with TMobile? In the beginning... the coverage at our home was fine. Over time we noticed that we couldn't get bars unless we turned the phone off and then on again. Eventually that didn't work and we'd just have to stand outside on the porch (yes, even in the winter) to make calls. Receiving calls was a problem - they'd go right to voice mail and I'd get the tone that I had message and a missed call - but it never rang. In the last few weeks going outside hasn't helped, so either there is too much competing with the signal, or it is part of my (and hubby's) phone giving up the ghost. Daughter is already on a prepaid Verizon phone - and we still pay the $5/mo to keep her line to avoid paying a penalty to move her number. So she got a new number - she's a teenager - she'll get over it.
Took an informal survey in our neighborhood. Some neighbors cannot have Verizon because of where we are located (people directly across the street from me!), but I've had two people plus daughter test their phones at our house and it's good. Some can't use Sprint for similar reason - we have dead zones in our neighborhood. And, no, we're not in the boonies, we're in a well-established, thoroughly populated suburb of Baltimore.
Now that my phone is giving me trouble in my office, I'm having difficulty waiting until Oct to change. I work part time so I don't give out my work phone; I don't want friends, doctors, family, etc bothering the folks at work when I'm not there. So my cell phone is my phone at work. But now the conversations are garbled. And the keypad types pretty much what it wants (multiple letters, ignores ALT key, skips some letters, skips spaces)
