You are exploring Europe, navigating with Google Maps, uploading photos to your travel blog, and streaming your favourite tunes when suddenly, your internet slows to a crawl. You've bought an "unlimited" eSIM plan, so what's going on?
Like many other travellers, You have just run into something called the Fair Usage Policy (FUP).
The term might sound like, what the hell is that, but it's one of the most important things to understand before choosing a mobile or eSIM plan, especially if you're abroad.
Let’s decode it simply, without the tech headaches.

The Fair Usage Policy is a set of limits that mobile and internet providers apply to "unlimited" data plans. It’s meant to prevent overuse by a small number of users so everyone gets fair access to the network.
For travelers using eSIMs, this is especially important. You may think you’ve got endless data, but if you stream or hotspot too much, your speed might be throttled.
Think of a mobile network like a highway. If too many people drive on it at once, traffic jams happen. The FUP is like traffic control. It helps keep the digital road clear by reducing speeds for heavy users once they hit a certain amount.
It ensures fair connectivity for all, especially during peak usage times.
Even if you’re not a heavy user back home, travel often turns you into one. Navigation apps, social uploads, and video calls back home can eat through data fast.
Remote workers, digital nomads, and long-term travellers are especially vulnerable to FUP restrictions.
A data cap is a hard stop. You buy 10GB, and when it's gone, it's gone. FUP, on the other hand, doesn’t cut you off. Instead, it slows your speed after you've hit a certain threshold, like reducing a highway speed limit from 100 km/h to 30 km/.
Both are limitations, but FUP is more subtle and often catches travellers off guard.
Once you cross the FUP threshold, your internet might:
You won’t lose access entirely, but the quality of your connection will change.
Here are practical tips to avoid hitting your FUP:
Yes, it does. eSIM providers often partner with local carriers who apply their own FUP limits. Even if your eSIM plan says "unlimited," the fine print might say you’ll get 4G up to 20GB, then 2G afterwards.
Always read the plan details or ask customer service directly.
