How to Audit Your Company Mobile & Phone Bill in 10 Minutes
A practical 5-step checklist for UK directors and finance managers to spot ghost SIMs, CPI+ price rises, out-of-bundle charges and contract end dates.
1. Count active employees vs billed SIM numbers (Ghost Lines)
In fleets of 15 or more lines, we routinely find 1 to 4 SIMs still being billed every month for staff who left the business months ago, or old 4G tablet/router SIMs sitting in a desk drawer. Identifying zero-usage lines over a 60-day window is the fastest instant saving.
2. Check contract end dates and annual April price rises
Once a 24-month handset contract finishes, networks often keep charging the full handset-inclusive monthly price even though the phone has been paid off in full. Switching those lines to commercial SIM-only rates immediately drops the bill by £15 to £30 per line each month.
