The origin of the failure is not yet known.
But mobile and fixed communications between Orange subscribers and those of SFR no longer go through.
The causes of the incident are not yet known, but the two operators claim to be in a crisis cell.
They are working together to try to resolve the incident quickly.
It is still too early to determine where the origin of the malfunction lies.
Communications between Orange subscribers, or between SFR subscribers and with those of Free or Bouygues Telecom are not affected either.
The failure seems to be limited to only communications between Orange and SFR.
