If you only need a small amount of data in Budapest and Vienna then probably get the T-Mobile SIM and add an EU roaming package. Otherwise you will most likely have to buy a new SIM for each one.

This assumes you are going very soon. Things may look better once 15-June rolls around and the new regulations come into effect.
