Hi guys , i have a data plan that only allows me check the remaining 3g data and check my plan account using the menus from the SIM. Since n900 does not support STK, is there anyway to extract the USSDs from a SIM CARD MENU ?

To guys from Brasil: Anyone knows the USSD to "Consulta Saldo OI Conta" from OI ?

I googled and find the ussd codes for other operators but not the one i need...
