Yeah, I agree. You can use any Slovak SIM card at domestic SK prices roaming in Germany and Greece. So it's suggested to buy a SIM in Slovakia and bring it to the other two countries. The three major providers are the easiest bet: Orange, Telekom and O2. They will all offer you similar packages. Be sure to have topped up your SIM or loaded enough data before having left SK as some top-ups from abroab may be harder to do.
