I have been using sunrocket for almost a year. There were a lot of problems with it when I first signed up. Problems getting my old phone number back, problems getting it to work right, getting sound clarity. After several months, those glitches finally ironed out and it worked well. But for the past several months, problems have been growing again. I'm having trouble calling out on the phone. When I tried to reach a tech support line, I found they no longer provide that service. You cannot call Sunrocket for help with problems that occur. Nor am I getting any responses with email. I have left email messages that have not been returned.
I am afraid that they are going out of business. Whatever the reason, service is non-existent. Do not waste your time and money on this company!
