I called today TP-LINK services, they told unfortunately Bezeq works hard to keep its monopoly, so that worldwide routers aren't supported on Bezeq line, the only internet line in Israel. Really Bezeq tells all time to use only their routers/models, while in same time its technicians says "know that Bezeq has full remote access to all devices connected to its routers, is able to install anything, etc.".
