hasn't sprint added this ability on the website? when logged in you can add numbers that you want blocked or something like that....
I myself need to check into this. I tried to get an online insurance quote thinking it was going to give me rates and such...unfortunately it sent out my contact info to 100 insurance companies ...3 of which call me 5 or 6 times a day
ok never mind sprint allows you to block texts but I can't find anything on the call part...
only found this :
