888-266-7848 The number I use is 888-266-7848. Good luck though getting any kind of decent service. I have been going through a total nightmare with them just to order another phone. Seriously, I have to say Boost has the absolute worst customer service I have ever had to deal with in 65 years. I'm to the point of switching even though I will have to pay more.
