In 2014, O2 had cancelled roaming charges between Slovakia and Czech Republic for calls, SMS, MMS and data. People traveling in a public transport heard a public service announcement telling them they don't have to pay an extra penny abroad if they're an O2 (and that may the clients of other carriers have also a pleasant trip).
The TV spot for the concept was made by VCCP Bratislava.

The concept has won a shortlist in the Zlatá pecka 2014 awards.
