Unfortunately, with Sprint - and we have tried them twice - we have had little to no service in vital areas of our city - the school, the store, our home...and the customer service was extremely poor. Our last foray into Sprint was two years ago, and our daughter couldn't get a signal to call us from her school. We are in a pretty major metropolitain area, and the other providers (even t-mobile) don't have difficulty.

I've been with Sprint for years ... and yes, there was a time when they deserved a reputation for worst customer service, but that is more than 4 or 5 years ago.
The customer service I've received, on the rare times I needed it, has been right on the mark. The phone connections and data speeds have been fine... as in, I don't see friends with other services getting faster results ... but I do see them having data limits ... while my plan is unlimited ... I'd definitely recommend them

For price and included features Sprint is hard to beat. Recently however I made the switch to a competitor after doing business with Sprint for almost 8 years. While they had made many improvements, in my line of work I needed a hotspot with great speed, great signal and lots of included data. The competitor beat Sprint by nearly 10x on speed in my area and included twice the amount of data. Yes it was a little more expensive, but it's what I needed.

Always have had excellent service from Sprint, both when I lived in Florida and here in California. At home, I live in a relatively dead coverage area for all providers (nestled among the mountain foothills, shielded from towers), so my signal at home was poor. When I mentioned this to a Sprint rep, she immediately offered an Airave femtocell unit, free of charge, which arrived a day or so later and completely solves the problem. Never had a bad interaction with any customer service or accounts people in the 13 years we've used Sprint.
