Client stories
These notes come from operators, MVNOs, and wholesale teams who commissioned concrete reviews — not anonymous star ratings.
“The sample window caught under-rated roaming events that our internal check had skipped because the partner feed arrived a day late. The memorandum named the exact tariff rows, which made the finance conversation shorter.”Amira Hassan, Revenue assurance lead, Penang-based MVNO
“We needed interconnect settlement checked before a contract renewal. DigiInfra AI Digital was careful with our CDR extracts, though the first draft asked for a second mediation file we had already archived — once that arrived, the variance table was clear.”Wei Ming Tan, Wholesale settlements manager
“The app analytics review showed which usage events never reached rating. It was less about glossy charts and more about which handset sessions dropped before mediation.”Priya Nair, Product operations, prepaid app team
Extended case notes
Prepaid roaming under-rating after a zone map update
An MVNO in northern Malaysia asked for a [Telecom Billing Validation Audit](/services/telecom-billing-validation-audit/) covering one prepaid roaming product. A zone map change had shipped mid-cycle. Reconstruction of 1,200 sampled events showed under-rating on three destination groups when the old map still applied to late-arriving CDRs. Finance adjusted partner accruals before month-end close.
Interconnect minutes disputed at renewal
A wholesale desk commissioned an [Interconnect Settlement Review](/services/interconnect-settlement-review/) ahead of renewing a voice partner. Settlement files and rated events disagreed on weekend peak codes. The findings note separated timing rejects from true volume gaps, which shortened the commercial meeting and avoided a blanket credit the partner had requested.
