# What "Unlimited" Actually Means on an eSIM Plan > Unlimited rarely means unmetered. What the fair-use threshold is, what happens when you cross it, and the trips where unlimited is still the right buy.

The number is what you are actually buying.* Almost no unlimited mobile plan is unmetered. The standard arrangement is a generous allowance at full speed, after which the connection is slowed — often dramatically — for the rest of the period. You are never cut off, which is what lets the word stand. That is not automatically a swindle. It is a real product with a real use, and for some trips it is the correct buy. But it cannot be compared with a metered plan on price alone, and the number that decides whether it suits you is usually buried. ## The number that matters Every unlimited plan has a fair-use threshold: the point where full speed ends. It might be 1 GB per day, or 10 GB for the period, or an unstated figure the provider reserves the right to apply. Find that number before you buy, and compare it against [what you actually use](https://esimradar.com/blog/data-usage). An unlimited plan with a 1 GB daily threshold is a 7 GB weekly plan wearing a better word — and if a 5 GB plan costs less, the comparison is not close. ## What happens after the threshold The post-threshold speed is the second number to look for, and it decides whether the plan is still usable or merely still connected: - 512 kbps to 1 Mbps — maps, messaging and email work; video does not. Tolerable. - 128 kbps to 256 kbps — text-based things load slowly and everything else effectively stops. - Unstated. Assume the lower band, because a provider confident of the figure tends to publish it. [How throttling works](https://esimradar.com/blog/data-throttling) covers the mechanism. > **Note:** Tethering is where unlimited plans are most often restricted, separately from the main allowance and sometimes excluded outright. If a laptop is going to live on the connection, [check the hotspot terms specifically](https://esimradar.com/blog/esim-hotspot) rather than assuming the headline covers it. ## Why the disclosure varies so much In regulated markets, disclosure is not optional. US broadband providers, including mobile ones, must publish [a consumer label](https://www.fcc.gov/broadbandlabels) stating the data allowance and linking to a network management policy that covers throttling. The UK constrains the word rather than the label: [the CAP advice on unlimited claims in broadband and telecoms ads](https://www.asa.org.uk/advice-online/broadband-and-telecoms-unlimited-claims.html) allows "unlimited" only where any limitation the provider imposes is moderate and would not surprise the average customer. The EU takes a third approach and writes the threshold into law. Under [the roaming regulation that runs to 2032](https://eur-lex.europa.eu/legal-content/EN/LSU/?uri=CELEX:32022R0612), an operator may apply a fair use limit to a domestic plan used abroad, and that limit has to follow a published formula rather than a number of its choosing — which is why [an unlimited home plan behaves differently once you cross a border](https://esimradar.com/blog/free-data-roaming-europe). Travel eSIM resellers generally sit outside those regimes. Nobody compels them to state a threshold, which is why some do and some leave it to the terms of service. The absence of a published figure is itself information. ## When unlimited is the right buy Three cases, and they are genuine rather than grudging: 1. A long trip where you cannot predict usage and would otherwise top up repeatedly. 2. Heavy video or hotspot use where even a large metered plan would run out, and slow beats nothing. 3. Any trip where you would rather not think about it. Paying a premium to stop monitoring a counter is a legitimate purchase. What it is not good for is a short trip with ordinary usage. There, a metered plan is almost always cheaper and never throttled. ## How we rank them We rank on price per GB, and an unlimited plan has no GB figure to divide by — so it cannot be placed honestly in a list sorted that way. We show them with their threshold where the provider states one, and say so where they do not, rather than inventing a number to make the sort work.

Most give a fair-use allowance at full speed and then slow the connection for the rest of the period. You stay connected, which is what lets the word stand. ### How do I find the fair-use threshold? The terms of service, usually. If the provider does not publish one anywhere, treat that as a warning rather than as an absence of limits. ### Is unlimited better value than a large metered plan? Only for long or unpredictable trips, or heavy video and tethering. For a normal week a metered plan is usually cheaper and never throttled. ### Does unlimited include hotspot use? Often not, or only up to a separate smaller cap. Tethering is the most commonly restricted part of an unlimited plan, so check it specifically. --- More guides: https://esimradar.com/md/blog.md Compare plans by destination: https://esimradar.com/md/destinations.md
