Dear Valued Customer,

We would like to inform you that O2 UK engineers will be conducting an essential upgrade to a core node within their infrastructure. As part of this process, PDP sessions on the primary link will be cleared and redirected to an alternative link to minimize any potential impact on data services.

During the scheduled maintenance window, existing sessions will be temporarily cleared, and the device will automatically establish a new session on the alternative link. Please be assured that this will be seamless and largely unnoticed by most customers. New sessions will remain unaffected.
