Who is this customer and how they use data

This is not a tourist visiting for a week. This is a UK resident — someone who lives and works in London and uses mobile data as their primary connection, without relying on a fixed contract with a local operator.

This type of user exists and is more common than you might think: expats, mobile workers, professionals who manage everything from their phone or share the connection via hotspot with laptops and tablets. For them, the word “unlimited” is not a bonus — it is the minimum requirement.

And the numbers you are about to read show exactly what “unlimited” means when there is no Fair Usage Policy throttling traffic after the first few gigabytes.

Real data: day by day

The following table shows the aggregated daily consumption, extracted directly from the official system log (UTC+0). The ICCID is partially masked to protect the customer's privacy.

Analysis • 16 June

95.62 GB in a single day: what happened?

The log shows three consecutive sessions in the early hours of 16 June: 68,626 MB at 00:53, 22,415 MB at 00:26 and 6,751 MB at 01:53. This was almost certainly an automatic cloud backup (Google Drive, iCloud or similar) or a scheduled background download — operations many devices run automatically overnight while charging. No traditional operator with a FUP would have let more than 10–20 GB pass without reducing speed. Here, nothing happened. The connection held.

What would have happened with a traditional operator

Most mobile operators, both British and Italian, apply a Fair Usage Policy (FUP): a threshold beyond which speed is drastically reduced, often to 1–2 Mbps. In some cases traffic is blocked entirely until the next day.

FUP values refer to typical market conditions. Details vary by operator and plan. For an in-depth comparison across 9 operators, read our FUP comparison article.

Why Blivale does not throttle after a certain amount of traffic

The Blivale UK eSIM operates on Vodafone, EE, Telefonica O2 and Hutchison networks with a no Fair Usage Policy policy. This means traffic is not counted against a monthly threshold and speed is not programmatically reduced.

The guaranteed minimum speed is 10 Mbps under normal network conditions. Traffic resets automatically every 24 hours. The hotspot function is included without restrictions: the case study customer almost certainly shared the connection with other devices, which explains the high volume especially overnight.

Who is this eSIM for

The case study you just read describes a specific profile. But there are many situations where consuming even just 20–50 GB in a few days in the UK is the norm, not the exception:

All plans operate on the same networks (Vodafone, EE, O2, Hutchison), with the same conditions: no FUP, no speed limit, hotspot included, instant QR activation.
