OpenCall – Open the world of cheap calling!

Virtual operator OpenCall was launched in September 2013 and following the sale of over 130 000 SIM cards during the following years, became one of the most successful MNVOs on the Czech market. From the very beginning we were focussed on favourable call rates, great customer care and a wide distribution network. In 2016 we began cooperation with O2 and achieved a significant improvement in terms of coverage and quality of our data services offered whilst keeping the low calling rates.

In OpenCall we have an international team, and because of this we are fully aware of how important it is to not to lose contact with friends and family back home when you are abroad for the long-term. For this very reason we offer unrivalled International calls rates. For instance, did you know that with OpenCall you can call to Vietnam from 1,8CZK or to African countries from just 5CZK per minute?
