Case Study: O2 UK prevents bill shock and protects revenue with Sandvine real-time usage notifications

O2 UK Takes the Shock Out of Bills

Telefónica O2 UK, a major UK mobile operator, faced widespread "bill shock" when postpaid subscribers—especially while roaming—incurred unexpectedly large data charges that many were unwilling or unable to pay, leaving the operator to absorb significant costs. To address this, O2 UK partnered with Sandvine to find a preventative solution.

Sandvine deployed real-time usage monitoring that sends customers notifications at configurable thresholds and enables easy data top-ups via O2’s bolt-on options. The approach reduced bill shock, improved the subscriber experience and engagement, helped prevent revenue loss from unpaid roaming bills, and gave O2 clearer network and customer insights that improved revenue opportunities and cost-effectiveness.
