Re: can't dial neither USSD codes / nor GSM codes on my BB Storm 9530
Some carriers block Short Code SMS messages. If you call them they will enable it on your account. Sprint does this because so many scam billing schemes come this way. Users suddenly get a $10 recurring monthly charge because they "opted in" on one of these schemes without even realizing what was happening, all because they answered a harmless looking text message. Then Sprint fields a bunch of angry calls to customer service, asking what the heck such-and-such charge is for.
