Development of an unstuctured supplementary Service Data [closed]

I want to wrap 3 ussd codes,e.g *456#,*567# and *456# that independently allows me to subscribe to a product into one single ussd code.e.g.*3456#.such that when I dial *3456#. it allows me to subscribe to the products offered by the 3 codes at once.please help me through

I tried developing the code and I was expecting a ussd code that could subscribe to the products automatically
