Either way, the effective rate per MB ends up higher than straightforward PAYG.
Example 1 — unused data
A company buys a 1,000 GB pool at £3 per GB = £3,000. If they only use 700 GB:
Effective rate paid
£4.29 per GBvs £3.00 quoted
Example 2 — overage penalties
Same pool, but 1,200 GB used. 200 GB overage at £5/GB adds £1,000 to the bill.
Effective rate paid
£3.33 per GBvs £3.00 quoted
Example 3 — uneven usage across 100 SIMs
High usage (20 SIMs)
10 GB each → 200 GBModerate usage (50 SIMs)
4 GB each → 200 GBLow usage (30 SIMs)
1 GB each → 30 GBTotal usage: 430 GB out of 500 GB pool. The problems with this arrangement:
No waste. No penalties. No cross-subsidisation. Just predictable, fair billing per SIM.
