Last time Vodafone EG was my ISP it was using PPPoE for vdsl2/fttc lines maybe things changed since then,, I think the issue is that line port has changed when FTTC cabinet installed and really there is no co-ordination between other ISPs and Telecom-Egypt which is playing 2 rules (TE) first as an ISP by itself and the second it owns EVERYTHING in the phone line / broadband infrastructure leasing the equipment and bandwidth to other ISPs so they must require re-activation of service on the lines subscribed with them and it takes sometime cause I think TE is making the process take longer time than it should be so other ISPs' subscribers get bored and change the ISP to TE which takes much less time in service activation, subscribers who are already with TE service works flawlessly with only time out of service when lines are sorted out in the cabinet.
The best thing UK did is separating OR from BT, cause in our situation things are really really messy.
