I had Sprint for 10 years before switching to Cricket.
In terms of the price, the $50 plan shakes out to be $60+ a month.
The quality of phone isn't the best. Battery dies quickly from the minute I got it. Don't have good reception at home but other phones have been just fine.
A small thing and a minor annoyance but an annoyance nonetheless. I dial 411 to get a number for somewhere and that isn't part of the $50 plan.
Overall it's "ok" but just because of the price being much less than Sprint. Still looking around for something that fits me "better".
