Hello, does anyone know here, with which code one examines the Handy-credit?

Nothing to do with the mobile phone type.

Which provider do you use? (AIS, DTAC, TRUE...)

I think you find your info here:

Balance check:

*103*8*9#<dial>

 

They show for different for "Happy Tourist SIM".

As I am not familiar with DTAC I can't tell what applies:
