T-Mobile has notoriously spotty coverage and notoriously bad building penetration. Trivial amounts of research would have ruled them out as a choice for many people working in a hospital.
If you work in a hospital they are one of the worst carrier choices because you will be beyond several solid walls a lot of the time.
Wi-Fi calling is only attractive to me if implemented similar to UMA was on Blackberry smartphones - where they'd hand off to and from Wi-Fi/Cell Towers as you moved in and out of range of Wi-Fi. I had T-Mobile and even with the terrible coverage I got I kept Wi-Fi calling off because it was too much trouble to have to hang out and call people back when I had to leave one place or another since leaving the Wi-Fi hotspot range would drop the call.
Pick a carrier based on your budget and your needs. Sometimes it's worth paying more if you're getting better service - which you will on most any other national carrier if you travel between cities and across the country even occasionally.
Verizon's locked CDMA phones have never been an issue because their 3G Coverage is better than anyone else's and their LTE now covers 99% of their 3G coverage. Additionally, almost all "recent" Verizon devices are Global devices so they are usable if you travel out of the country and have to roam on a GSM network.
All these clich? phrases bashing the other carriers won't change the fact that if the OP had them, you'd have better coverage on his device in that building compared to T-Mobile.
You get what you pay for.
