I have an lg phone that said it would work but would not activate I then found I'm the help section that I should dial ##72786# which reset the phone (not a hard reset that erases everything) after I did that it rebooted and now it works (as great as sprint can work)
I have a Verizon phone paid by my business and I have a Sprint phone which I pay for. The area I live in Sprint has the BEST reception, I tried all 4 carriers. In my house Verizon doesn't work at all, but Sprint is strong!
And another plus, you can get credits whenever you want, I call them every other month and get refunds for all extra charges like international calls, etc. and sometimes just goodwill credits... I can say that in the past 6 months I've gotten 4-5 hundred dollars in credit and adjustments...
