Hi.
My operator offers some kind of menu with USSD. You enter *111#, operators sends back Menu with numeric choices.
Now I use USSD pad to use it, unfortunatelly, Menu is too long for short USSD pad display.

Is there way to increase display size?

You have three options:
1) Hack up ussd-pad code yourself
2) Find somebody who can and wants to do it
3) Use console tool. Type in terminal "ussdquery.py interactive". Not as nice-looking as ussd pad, but would work.

you can use ussd-widget leaving spaces between the choice numbers.
What I mean is this: Normally I would dial *111# and get back a menu, then press 1 for 'Balances' and press enter and get back choices for which balance I want. I would then enter 7 for Data Bundle balance and would then get my balance returned.
Using ussd-widget, I set up the following ussd number:
*111# 1 7
The ussd-widget will first send the *111#, when it gets a response it will send the 1 and then again the 7.
All I get to see is the end-result - I click on the widget, it reads "Processing" and then after a few seconds it reads "You have 10GB available to use" (or whatever) ...

The fact is I can't see the start of USSD menu. And bottom choices overlaps keypad.
I think I will try to hack ussd-pad.
