Mine is SmartBro Prepaid... so far i have no other complains other than sometimes during bad weather the signal is not good. It works ok, almost the same as the SmartBro postpaid as we are using it in school. Its also economical on my side and I don't need to pay the monthly bill. If you want to use the smartbro prepaid, just be sure you have a smart broadband site and 3G signal in you place. And the speed also depends on the place if they have the broadband signal speed is faster or the usual 384kps.
