Overpaying and Under‑billing Due to Inaccurate Roaming Settlement and Reconciliation
Definition
Mobile operators routinely lose revenue or overpay partners because TAP/BCE settlement files are incomplete, late, or incorrectly rated, and manual reconciliation fails to catch all discrepancies. Vendors explicitly position roaming settlement solutions around ensuring operators “pay only what you owe” and preventing “unnecessary outpayments,” which implies recurring leakage in the absence of such controls.
Key Findings
- Financial Impact: Industry vendors and GSMA‑linked analyses indicate that operators adopting near‑real‑time BCE and advanced validation reduce roaming settlement disputes by about 30%, implying that a material portion of wholesale roaming cash flows (often in the tens to hundreds of millions per large operator per year) is at risk without proper reconciliation; specific operator‑level dollar amounts are usually confidential but the exposure is in the multi‑million‑dollar annual range.
- Frequency: Monthly
- Root Cause: Root causes include reliance on legacy TAP standards that are not fit for high‑volume 4G/5G and IoT traffic (leading to missing data and delayed usage records), independent rating and invoicing calculations on each side of the roaming agreement that create mismatches, and fragmented or manual reconciliation processes that do not systematically re‑rate partner files against contract terms. GSMA and solution providers highlight that current wholesale roaming settlement requires complex reconciliation of rates, management of missing/late data, and handling frequent rating and invoicing disputes, all of which create room for systematic under‑billing or overpayment when not automated.

Deep Analysis (Premium)
Financial Impact
$1M-$5M annual from undetected systematic under-billing (operator fails to bill roaming usage to end-customers) and over-acceptance of partner invoices due to weak forensic trail; regulatory audit risk if roaming revenues cannot be reconciled to CDRs • $2M-$8M annual leakage per operator from undetected duplicate charges, late penalties, incorrect rating due to incomplete or late files; disputes take 90+ days to resolve, delaying cash collection • $300K-$1.5M annual for mid-sized MVNO from: (1) customer refunds due to disputed roaming charges (wholesale errors passed through), (2) churn from customer dissatisfaction with roaming billing accuracy, (3) manual correction costs and re-work
Current Workarounds
Custom SQL queries against CDR database to count expected roaming events; manual pivot table comparison against partner invoices; email escalation to Roaming Settlement Analyst and Finance when variance exceeds 5% threshold; Excel-based trend tracking of monthly variance rates • Download host operator settlement CSV; upload to billing system; if system rejects records (field mismatches, date format errors), manually correct in Excel and re-upload; track corrected records in spreadsheet to investigate later; pass through charges to customers even if doubts about accuracy exist • Finance, roaming, and partner management teams export TAP/BCE records and internal CDR/EDR data into spreadsheets to manually sample, re-rate, and match charges; circulate discrepancy lists via email/WhatsApp, and track disputes and adjustments in ad‑hoc Excel trackers and shared drives instead of using an integrated roaming settlement and reconciliation system.
