The network issue we are currently experiencing remains a top priority for us and we are working as quickly as possible to fix the issues.
All O2 technical teams are working closely with one of our third party suppliers who has identified a global software issue in their system which has impacted data services. As a result of this incident, we are experiencing a high demand on our network which means some customers may have issues making and receiving voice calls.
We believe other mobile operators around the world are also affected.
We apologise to our customers for any inconvenience.
