you can add all your favorite USSD code, even those that needs an input, you can do that by putting your code USSD like that : eg: *133*N*M*C# (in this code you said to the app that you need three text field and the first one go to the place of "N"....). *133*N*M*C# : i need 3 text field.
*133*N*M# : i need 2 text field.
*133*N# : i need 1 text field.
In the setting enter your code: for exemple crédit transfert: *133* N (stand for phone Number) * M(stand for money) * pine code(if you have one)#
eg: sold: *122#
Recharge: *133*C (stand for Card number)#
Call me: #124*N#
