This is how balance checking works on Blau, also.
I'd try *111# but
I'm out of credits and can't buy e-Plus cards in the US.
O2 even offers a full menu with response-possibility if you use *100#.
Balance is *101#, but you can also use *100# and choose 1 then. It
also allows you do send full texts etc back where necessary.
