1. What Is FUP (Fair Use Policy)?

The FUP — Fair Use Policy — is a contractual clause that almost all telecommunications providers include in their general terms of service. On the surface it appears to be a fairness measure: it is designed to prevent a small number of heavy users from saturating networks at the expense of everyone else.

In practice, for anyone who purchases an "Unlimited" eSIM for travel, FUP means just one thing: your connection speed is drastically reduced — often to 128 kbps — once you have crossed a data consumption threshold, which may be daily or total. Your data doesn't run out: technically you are still "unlimited." But the speed is so low that the vast majority of modern applications become unusable.

2. How it works in practice: real-world speeds

The FUP activation threshold varies from provider to provider and from plan to plan. The most common values in the traveller eSIM market in 2025–2026 are:

• 1–2 GB per day at full speed (4G/5G), then throttling
• 500 MB per day for hotspot (tethering), regardless of total data
• Reduced speed to 128 kbps, 256 kbps or 512 kbps after the threshold
• Deprioritisation on congested networks (less visible, but real)

Here is a visual representation of what this means in terms of bandwidth:

For reference: first-generation 3G networks ran at around 384 kbps. 128 kbps is less than a third of that speed — we are back in the GPRS era, early 2000s. At that speed, loading a simple web page takes 15–30 seconds.

3. What you can (and can't) do at 128 kbps

This is the part no provider shows on their sales page. Here is a realistic map of what works — and what doesn't — at reduced post-FUP speed.

The picture is clear: an eSIM with active FUP is useless for remote work and very limited even for heavy personal use. This applies to tourists streaming content, and even more so to entrepreneurs and digital nomads.

4. Why FUP exists: technical and economic reasons

It is fair to be honest: FUP is not always a deception. It has concrete technical and economic roots.

Mobile networks are shared infrastructure

When an operator purchases roaming rights from a local network, it pays for the capacity used. If too many users consume large amounts of data at high speed, the network becomes saturated and everyone suffers. FUP is a tool for distributing bandwidth more fairly among all users connected at the same time.

The cost of wholesale roaming in Europe

The European Commission sets a maximum ceiling on wholesale roaming costs: in 2025 it stands at €1.30 per GB plus VAT, set to fall to €1.00 per GB from 2027. This means that every GB consumed in roaming has a real cost for the provider. An "Unlimited" plan sold for €30 with aggressive FUP often conceals the mathematical impossibility of genuinely offering unlimited data at that price.

5. Who applies FUP: analysis of 9 providers

Below is an overview of the main international eSIM providers, with particular focus on their FUP policy, based on their publicly available terms of service and independent sources updated to 2025–2026. We do not label conditions as better or worse in absolute terms: every model has its audience. The goal is transparency.

6. How BLIVALE works: the 4 types of eSIM explained

BLIVALE doesn't have a single eSIM model. It has four distinct product lines, each with different features and usage logic. Understanding which one suits you is essential to avoid surprises.

8. How to choose the right eSIM for you

Use this quick framework based on your usage profile:

🧳 Tourist with light use (social, maps, messaging)

A fixed-GB plan (Airalo, Nomad, Ubigi, BLIVALE Standard) is often the most affordable choice. You don't need "Unlimited" — you need enough GB at full speed. Rule of thumb: ~1 GB per day of light travel.

💼 Business owner or professional travelling

You need guaranteed speed, the ability to receive calls and banking SMS, and a hotspot for your laptop. The right choice is an eSIM with no FUP, native voice and SMS, real number. In Europe: BLIVALE eSIM Unlimited Premium.

🌍 Digital nomad (heavy multi-country use)

You're looking for maximum speed for many hours a day, a stable hotspot, and often need to be reachable on a European number. Look at the most capable plans and consider investing in a Premium plan without FUP as protection for your productivity.

✈️ Frequent traveller with alternating intensity days

If you alternate intensive with lighter days, a hybrid plan such as BLIVALE eSIM Unlimited Smart can offer you flexibility: high speed when you need it, with a daily mechanism that resets every 24 hours.
