I am customer of O2 in my home country - Slovakia and I currently live in Czech Republic. O2 recently came up with a program that allows me to pay exact same charges as I would at home (both phone and data). It is much simpler to have one number than numerous SIM cards...

O2 SK always had a somewhat funny relationship with Czech republic. It used to be cheaper to call from Slovakia or from roaming in CZ, than local Czech calls.
