Quantifiable Test Strategies with Substantial ROI Results

The following are a few examples of genuine revenue and network assurance issues discovered by our test services:
  • 5% of PostPaid Mediation CDRs were missing and unbilled by an Operator.
  • Our TCG system detected £89k of lost revenues in a single day (£2.49 million a month), over 700,000 Voice and SMS unrated CDRs were recovered by one Operator.
  • TCG Data usage tests detected large amounts of free rated Data which should have been charged, the estimated revenue loss was between £50k-150k per day (£1.4 - £4.2 million a month).
  • Roaming tests identified data usage allowances exceeded the expected cap rate whilst testing roaming Sims in the USA.
  • An error was detected in a PrePaid IVR platform that prevented customers from topping-up/adding credits.
  • A Voice and SMS 'free' bundle tariff plan was applied twice during the same month, consequently around 30% of the calls for this tariff were unbilled by the Operator due to a bundle rule error.
  • 12% of PostPaid short call durations between 300 milliseconds and 1 second were zero rated and unbilled by an Operator.
  • International testing revealed under-billed call charges to certain countries, due to the PrePaid platform using incorrect rates and country zones.
