I have 0 coverage at my work, i need coverage at my work as i have a business to run. Unfortunetly i thought the coverage might get better after using it for few days and forgot to take care of this within first 30 days. now i can't use a phoen that doesn't give me coverage. I tried to work with sprint support and i can't plug-in their airwave device into my corporate router. I want a phone that gets me calls, is there anyway i can get out of contract?
