I'm on Sprint now. I was on TMobile and had no issues with them but the price was killing me and since my wife lost her job, decided to look into the 50% off Sprint is offereing and the $200 offer they had on top of that and it worked out for us. $210/month at TMobile is now $86 a month at Sprint with three new LG G4s. I liked my Note 5 more, but the G4 is a good phone too. Service is pretty comparable to TMobile in my area.
VZW, been with them on our own plain since 2006, although they can be more expensive they do have the best coverage, especially if you travel all over the country.
I am with Verizon, there is no other coverage where I am in this rural area (not that I'm complaining). I also work for Verizon as a sales associate in a one door store. So business is nice.
I have been with Verizon since about 06. Many times complained that I would leave but then realized that the service I get with big red is better than any other. Been on unlimited the whole time and don't plan on changing that until they make me!!
Voted! Had Verizon a while back with unlimited data, but I switched to t-mobile so i could use my Oneplus (at&t was not an option for me). Currently, I'm paying less than I did with Verizon with 6gb of data that I don't even scratch because now music and video streaming doesn't count towards my data usage. I'm also very satisfied with the coverage.
