Sprint appears to have coverage in my area. I'm guessing you live in Indiana? How well did it work when you were in the U.P? I get constant calls that never ring and go to voicemail or not receiving texts, I'm sick of paying a premium price for what I think is mediocre service, what company is your work cell? how does it compare, and would you go back to ting if you had too?
Yeah I live in Indiana. Ting (on Sprint network) worked fine for voice/text in the UP - it has phone roaming so you should get phone service anywhere. The trade-off is it doesn't have data roaming. I don't care if I don't get data while on vacation in the middle of nowhere, but I can see that being an issue for some (if you stay in a hotel, they all have wifi).
My work phone is verizon, which in my experience has slightly better voice coverage than Sprint and quite a bit better data, but I will go back to Ting if I switch jobs and don't have a work phone anymore.
Give ting a try - no contract, just pay for what you use and you can buy a used sprint phone to see how it works. If you call them, a human answers immediately.
