Bought my sim card at Best Buy, registered my kudos account and bought a prepaid plan. Put my sim in my phone and no service. Tried rebooting many times, still no service. Then I read that I have to make sure my number is activated in my self serve account so I tried to login but says my account does not exist. Thought I would ask customer service what the problem would be but they are trying to charge me $30 for it! What a #$%&ing scam. I just lost out on almost $100. Only thing I can do now is warn others not to use Kudos. On my way to every forum I can find. #$%& you Kudos!
