Athens, Greece – October 2, 2025 – COSMOTE TELEKOM connects with Protergia, the energy of METLEN, to bring even more benefits to their customers. The world of MagentaONE and the world of Protergia Picasso come together, delivering a new offer for COSMOTE TELEKOM customers that combines internet and electricity. That means a discount on the fixed-line bill, along with energy solutions at the same cost[1] every month.
