Due to problems in the O2 mobile network today, our SIP2SIM customers may be having problems with data and calls.
O2 have advised that they believe they have identified the cause of the issues and are actively working to implement a fix.
Further information: Customers roaming on the O2 network are currently unable to establish data sessions. Customers roaming on the Manx and VodaNL profiles may experience difficulties in registering on the network impacting voice, data and SMS services.
O2 have provided the following update - "One of our third party suppliers has identified a global software issue in their system which has impacted us. We believe other mobile operators around the world are also affected." We will provide further updates as and when received from O2.

Our carrier says: O2 continue to work with their 3rd party supplier to resolve the issue. We are liaising with BT to manage signalling traffic levels to prevent further disruption.
Our carrier says: we are seeing an increase in successful network registrations in the last few minutes, we are continuing to actively monitor the network. O2 have advised that their software supplier continues to work to provide a permanent fix to the network issues.
From our carrier: O2 have advised that "Our third-party supplier and our technical teams are working closely together on deploying a software upgrade to fix the issue present on our MMEs. In the shorter term they're also investigating a workaround that could potentially be deployed a lot sooner than the upgrade." Further updates can also be found on the O2 service status page. http://status.o2.co.uk/ Manx Telecom continue to actively monitor the network and will provide further updates as and when available.
Our carrier says: O2 have advised they are in the process of deploying a workaround on 6 of their MMEs. We hope this will alleviate the service issues. There are no time scales for this work to be completed. Manx Telecom are continuing to see high levels of signalling traffic which we are continuing to actively monitor and manage.
Carrier services are starting to resume functionality now. A root cause analysis performed by by Ericsson reveals that the issue was caused by an expired certificate within O2s network.
