It depends on the season how many public payphone boxes are operated by Montenegro Card, a subsidiary of Telekom Montenegro, in which Matáv acquired a total of 73.04% holding on April 1, 2005. In the summer months when the tourists come more than 500 telephone boxes are set up, but by autumn their number falls back to around 300. Montenegro Card controls 60 per cent of the public payphone market, the remaining 40 per cent is covered by the competitor Montenegro post.
