Just some feedback: It's working fine here in South Africa on the Vodacom network. *100# returns balance as it's supposed to. We also have a USSD menu system whereby *111# brings back a menu of numbered items - you just enter the number on the menu and send that and it returns either a submenu or the result of your query. This is how prepaid users buy data bundles, check various balances etc. The menu doesn't display properly on ussd-pad - the top menu items are off the top of the screen and the bottom menu items are layered over the ussd keypad but the functionality does work - I successfully navigated through various menus to purchase a data bundle using ussd-pad. I also tried loading airtime which doesn't work, I think the string is too long for a buffer or something like that. We use *100*01*123123123# to load a voucher with the code 123123123, but a long error message was returned when attempting it...
