Even at $22/month, I still wouldn't leave T-Mobile. Unless Sprint service has somehow gotten miraculously better.
DO NOT BUY! No matter how good it sounds the service is horrific
FWIW, I jumped on the deal for a free year of Sprint (except taxes and fees) to switch from another carrier around Thanksgiving 2017. I switched from AT&T to Sprint. The former wasn't exactly awesome and Sprint isn't really any better (not that I expected to be). It has some downsides, but I'm thrilled with the price I'm paying for my 1st year.
I was paying $4.07/month and now it's gone up to $4.60/month. I'm still very happy with level of service for the price.
But, I also do carry a Verizon phone (for work) and usually another test device on T-Mobile. There are definitely places where VZ doesn't work or where 2 or all 3 carriers don't work well or work at all.
There's a monster thread at
https://slickdeals.net/f/10235008-s...-text-data-free-w-eligible-device-sim-req?v=1. My signup process was uhh... rocky and time consuming (long story short). But again, thrilled w/the price.
I'll have to see if I stick around after the year's up, but it doesn't look like any carrier w/LTE that's decent in the US w/visual voicemail is cheap.
Agree that it is annoying that more carriers are ahem... misusing the word "unlimited".
majority of BYODs don’t work on Sprints CDMA network
Maybe so, but one always needs to get a phone that supports CDMA networks. On Sprint, I'm using an iPhone 8 A1863, the one w/a Qualcomm modem that supports it. The other version

I bought it thru a Target Black Friday deal. They were handing out A1863 regardless of what carrier you were on. I used it for a few days on AT&T before paying it off in full, getting it unlocked and switching it to Sprint.
The wackiest part about Sprint though is that unlike virtually every other carrier where a SIM will just work in your (unlocked) phone given that it's the right size and the phone supports the right set of frequencies, you need the correct SIM SKU for your model!

Madness! Luckily, I was able to get the right SKU of SIM (SIMGLW416Q) for my phone for free from a local Apple store instead of waiting for Sprint to send me one.
