TL;DR
Unlimited travel eSIMs are not truly unlimited, they are capped. Every one of them gives you a set amount of data each day at full speed, then slows you down until the allowance resets. Roamless Unlimited Plans give you 3GB a day at full speed and 1 Mbps after that, and both figures are on every destination page before you choose a plan. The number that decides whether unlimited is right for you is your own daily use, and most travellers use far less than 3GB a day. What separates the providers is how much you get, how slow the slow speed is, and whether you can find that out before you pay.
What "unlimited" means on a travel eSIM
Unlimited plans typically mean unlimited in duration, not unlimited in speed. You get data every day of your plan and you will not be cut off mid-trip. What you will hit, if you use enough in a day, is a fair usage policy: the amount of data you can use each day at full speed.
Two terms get used interchangeably and mean different things.
A data plan is a fixed bucket. Buy 10GB, use 10GB, and data stops until you buy more. Every gigabyte runs at full speed until the last one is gone.
A fair usage policy is a speed ceiling for unlimited plans on a daily cycle. You keep data for the whole plan. Past the daily allowance everything still works, just slower, and the allowance comes back on the next cycle. On Roamless that means 3GB at full speed, then 1 Mbps until the allowance resets 24 hours later.
Fair usage is not a loophole invented by eSIM companies. It is a regulated concept: the European Commission adopted rules on fair use in roaming in 2016 as part of Roam Like At Home, precisely so that "unlimited" domestic allowances could travel without being abused.
Why two people on the same plan get different speeds
A travel eSIM is a roaming product. You connect to a local network under a roaming agreement rather than as one of that network's own subscribers.
When there's a lot of demand for data (think of a festival when your data disappears), that network's own customers are served first and other users tend to go to the back of the queue. This has nothing to do with your plan size or your provider. It is why two people on identical plans in the same city can get very different speeds, and why nobody can promise you a speed.
So the useful question is not whether an unlimited plan throttles. They all do. It is how much you get first, how slow it gets, and whether the provider tells you before you buy.
How much data a day actually is
A daily allowance of 2GB, 3GB or 5GB means nothing until you know what you get through in a day. Check your usage on an iPhone or on Android before you buy anything so you can see how much data you use on a regular day.
Here is what the apps most travellers live on actually consume.
Google Maps: around 5MB per 10 minutes of navigation
WhatsApp: 1MB to 5MB a day for text, 15MB to 20MB for a few minutes of voice calling
Instagram: 60MB to 80MB per hour of active scrolling through Stories and Reels
Spotify: 43MB per hour at normal quality, 144MB per hour at its highest
YouTube: 600MB to 900MB per hour at 720p, 900MB to 1.2GB at 1080p, 1.8GB to 2.7GB at 4K
Netflix: 1GB per hour in standard definition, 3GB per hour in HD, 7GB per hour at 4K
Zoom: 600MB to 1.2GB per hour for a one-to-one HD call, 1.5GB to 2.5GB per hour for a group call in full HD
TikTok: 840MB for 1 hour of scrolling in HD
Essentially, maps and messaging are close to free but videos can rack up data quickly. If you are traveling for work or like scrolling TikTok on trains and buses, you might find your data eaten quickly. If you have easy access to WiFi, you can comfortably live on 500MB per day.
Totals matter as much as daily peaks. Our guidance on how much data a week of travel takes puts a normal week at 1GB to 2GB and a heavy week at 3GB to 5GB. Set that against a 3GB daily allowance and most users won't ever come close to throttling, but an unlimited plan can give peace of mind if you don't want to worry about data while you travel.
Two things that will push you over your data limit
Streaming instead of downloading is the first. Pulling your maps, playlists and Netflix episodes down over WiFi the night before is the best way to save your data for when you need it.
Tethering is the second, and it is worse than people expect. A laptop on a hotspot pulls far more than the same tasks on a phone: desktop sites are heavier, cloud sync runs constantly, and a software update will eat a day's allowance while you are making coffee.
What the main providers give you before they slow you down
Here is what each provider states in its own published terms as of October 2026.
Provider | Daily full-speed allowance | Speed after that | Reset | Hotspot | Where you find out |
5GB | 1 Mbps or less | Every 24 hours | Allowed, "excessive" tethering prohibited, no figure given | Public help article | |
Roamless | 3GB | 1 Mbps | Every 24 hours | Included, from the same 3GB | Every destination page, before you choose a plan, and in the app |
3GB | 1 Mbps for the rest of the day | Every 24 hours from activation | No limit on tethering or number of devices | Dedicated fair use page | |
2GB | 512 kbps | Every 24 hours | Not stated | Plan document | |
Not published | Not published | Not published | Not published | Nowhere before purchase | |
eSIM.io | Not published | Not published | Not published | Not published | Nowhere before purchase |
What 1 Mbps and 512 kbps actually get you
So, you've hit your limit, now what? Is 1 Mbps actually usable?
Netflix's own recommended speeds start at 3 Mbps for HD, 5 Mbps for full HD and 15 Mbps for 4K. So no throttled travel eSIM will stream HD video, whichever provider you are on. Standard definition is the most you can hope for, and you will be seeing the buffering screen a lot.
Video calling is tighter still. Zoom's published bandwidth requirements put a one-to-one HD call at 1.2 Mbps in both directions and a group HD call at 2.6 Mbps up. A 1 Mbps throttle will not carry either. At 512 kbps you cannot hold even a 360p one-to-one call, which needs 600 kbps.
Throttling doesn't touch the core things you need when you travel. Maps, messaging and email work fine at 1 Mbps, the speed Roamless drops you to after 3GB. Zoom screen sharing without video runs on 50 to 75 kbps, and voice on 60 to 80 kbps, so an audio call with a shared deck is comfortably within even a 512 kbps throttle.
If you tether, read the hotspot column first
Hotspot is the least consistently disclosed part of the category, and it is where people get caught worst, because a tethered laptop burns through a daily allowance several times faster than a phone doing the same jobs.
Three of the six providers above say nothing about it at all. One allows it but prohibits "excessive" use without defining excessive, which means you find out where the line is by crossing it. On Roamless, hotspot is included and comes out of the same 3GB a day as your phone. If you are planning to work off your phone, decide this before you buy rather than on your second morning, and check what your provider actually permits for tethering a laptop or a second device to an eSIM.
Do people actually hit the daily limit?
Mostly not, going by what travellers report themselves. r/eSIMs is the most useful place to read this, because the people there have paid for the plans and post their real numbers.
The self-reported figures cluster well below what people expect to use. A short city break comes in around 3GB in total. A week of normal use, meaning maps, messaging, browsing and some photos, lands at 5GB to 10GB. Light users report getting through five weeks on 10GB. Two weeks in Japan including rural areas comes up repeatedly at around 20GB total. Against a daily allowance of 2GB to 5GB, none of those trips would ever throttle.
The people who do hit it consistently are a narrow group: travellers who skip hotel WiFi and stream instead, who report 30GB or more per trip, and remote workers tethering a laptop all day, who report 50GB to 80GB a month. If you are not in one of those two groups, the daily limit is unlikely to be what you notice about an unlimited plan.
What unlimited actually costs
Unlimited is priced by day and by destination, and the per-day rate falls sharply with duration. Roamless Unlimited Plans are available in every Roamless destination and run from 1 to 90 days, with the exact range depending on the destination. The table shows a selection.
Destination | 1 to 2 days | 10 to 20 days | 46 to 90 days |
Europe, the UK and Switzerland (32 destinations) | $3.85/day (AED 14.14) | from $2.55/day (AED 9.36) | $1.50/day (AED 5.51) |
United States | $3.85/day (AED 14.14) | $2.95/day (AED 10.83) | $1.50/day (AED 5.51) |
Turkey | $3.85/day (AED 14.14) | $2.95/day (AED 10.83) | $1.50/day (AED 5.51) |
Saudi Arabia | $4.70/day (AED 17.26) | $3.45/day (AED 12.67) | $3.25/day (AED 11.94) |
Canada | $6.85/day (AED 25.16) | $3.00/day (AED 11.02) | $3.00/day (AED 11.02) |
Brazil | $4.70/day (AED 17.26) | $3.60/day (AED 13.22) | up to 30 days only |
Mexico | $4.70/day (AED 17.26) | $3.50/day (AED 12.85) | up to 20 days only |
Prices are in USD, with AED at the fixed rate of AED 3.6725 to the dollar, and vary by destination within each group. Every plan in the table includes 3GB a day at full speed, then 1 Mbps.
When the maths favours a fixed data plan
Work out your total, not your daily peak, and the comparison gets easy.
Ten days in Europe on unlimited is roughly $30 (about AED 110). If your honest usage is the 1GB to 2GB a normal week runs to, you are paying around $15 (about AED 55) a gigabyte for the privilege of not counting. A metered plan or paying per gigabyte will be more cost effective.
The equation flips when your trip is long or your use is genuinely heavy. Six weeks in Europe at $1.50 (AED 5.51) a day is $63 (about AED 231) for six weeks of data you never think about, which is hard to beat any other way. Short trips and light users pay the most for unlimited; long stays and heavy users pay the least.
"People don't want to do gigabyte math on their trip," Ali Gazioglu, Co-Founder & COO at Roamless said. "They want to buy one thing, know the price, and get on with it. That's what Unlimited Plans are built for."
Unlimited or a metered plan: which fits your trip
Unlimited is not the best product. It is the better product for a specific kind of traveller and the wrong one for several others.
The beach streamer
You want to lie somewhere warm and get through a series without thinking about it. Unlimited is built for you, with one piece of arithmetic worth doing first: Netflix in HD uses about 3GB an hour, so one hour of streaming uses a full 3GB day at full speed and the rest of the day runs at 1 Mbps. If you don't mind downloading a few hours of TikTok or that new Netflix documentary over hotel WiFi, a fixed data plan might be better.
The heavy poster
Uploading Stories all day, voice notes, video calling home in the evening. This is the profile unlimited genuinely suits. Uploads are lighter than most people fear and social scrolling sits under 100MB an hour, so even an aggressive day of posting rarely troubles a 3GB allowance. You get the fixed price and the freedom not to check.
The remote-area traveller
In rural areas your speed is set by which local network your eSIM lands on and how far you are from a tower. A bigger daily allowance changes neither. What matters is which network your eSIM connects to and whether you can switch it manually. Strong coverage with a modest allowance beats a generous allowance on a weak network every time.
The worker tethering a laptop
A couple of hours of meetings, email and light tethering fits inside a 3GB day. A full working day does not.
Eight hours of laptop work with calls throughout will pass 5GB comfortably. Once you are throttled, a 1 Mbps connection sits below the 1.2 Mbps Zoom asks for a one-to-one HD call, so your camera is the first thing to go. On Roamless you can switch to Credits or a Data Plan at full speed for the rest of the day when the app tells you that you have reached 3GB.
The short trip and the multi-country trip
Three days away, or four countries in two weeks, the data plan you choose should be based on your own usage.
This is the case for paying only for what you use, and the trade-offs between buying data as you go and buying it in fixed buckets are worth working through properly before a trip with several stops.
"I bought unlimited for two weeks in Portugal because I thought I was a heavy user. I checked the app on the last day out of curiosity: I had averaged well under a gigabyte a day, and the only time I got near the daily limit was one long train journey where I watched films instead of downloading them the night before. The plan did its job though, I never once thought about data and just enjoyed my holiday."
Emily Waddell, Roamie.
One thing to do before you fly
Install your eSIM and top up your balance before you leave rather than after you land. Installing needs an internet connection, airport WiFi is unreliable, and in some markets eSIM providers' own apps and websites are blocked within the country, which leaves you unable to buy more data at the point you need it.
If you are setting up in the UAE, install your eSIM before you travel. WhatsApp and FaceTime voice and video calls are blocked on UAE networks, while messaging and data work normally, so use BOTIM, Zoom or Google Meet for calls while you are in the country.
Unlimited Plans from Roamless
Roamless Unlimited Plans are fixed-price plans sold per country and per region, available in every Roamless destination, from 1 to 90 days depending on the destination. You get 3GB a day at full speed, then 1 Mbps until the allowance resets 24 hours later. Both figures are printed on every destination page next to the price, and again on the plan detail screen before you pay, so you know exactly what you are buying before you choose a plan.
When you reach 3GB, the app tells you. You can stay at 1 Mbps for the rest of the day, or use Credits or a Data Plan at full speed until the allowance resets, and Credits are only used once you confirm. Hotspot is included and draws from the same 3GB.
FAQ
Is unlimited really unlimited data?
Not in the sense most people mean. It is unlimited in duration: you have data every day of your plan and you will not be cut off. It is not unlimited in speed. Every provider applies a daily full-speed allowance and reduces your speed once you pass it, until the allowance resets. What differs is the size of the allowance, the speed afterwards, and whether you can read the policy before you buy.
Is there a cap on unlimited data?
There is no total cap on most unlimited plans, which is the honest part of the claim. There is a daily one. Roamless and Airalo give you 3GB a day at full speed, Saily publishes 5GB and Nomad 2GB. Holafly and eSIM.io publish no figures at all. Pass the daily allowance and you keep working at a reduced speed rather than losing your connection.
How fast is unlimited data?
At full speed, as fast as the local network gives you. Because a travel eSIM is roaming, you can be deprioritised behind that network's own customers when a tower is busy, so nobody can promise you a speed.
After the daily allowance, published throttled speeds sit between 512 kbps and 1 Mbps, and Roamless drops you to 1 Mbps. Neither will stream HD video, since Netflix asks for 3 Mbps at that quality, and neither will carry an HD video call. Maps, messaging, email, voice calls and screen sharing all keep working.
Is unlimited data better than a data plan?
It is better at one thing: you know the price up front and you never think about consumption. If you know roughly what you use, a metered plan is usually the better buy. If you do not know and would rather not find out mid-trip, unlimited is worth paying for. It all depends on your usage, where you're travelling and for how long.
Can you get a global eSIM with unlimited data?
Not in any meaningful sense. Plans sold as global or worldwide unlimited cover a list of countries, not the world, and the list usually has gaps in places travellers actually go. Regional unlimited is the real version of this, and Europe is where it works best: one plan across the whole region. For a trip that spans regions, buying data from a single balance that works everywhere is more practical than stacking plans.
Is hotspot included in unlimited data?
It depends on the provider, and this is the least clearly disclosed part of the category. Roamless includes hotspot on every Unlimited Plan, drawing from the same 3GB a day. Airalo states there is no limit on tethering or the number of connected devices. Saily allows tethering but prohibits "excessive" use without defining it. Nomad, Holafly and eSIM.io do not address it in their published terms. Where hotspot is included it draws from the same daily allowance as your phone, and a tethered laptop gets through that allowance considerably faster.
What happens when I hit the daily limit?
Your speed drops to the provider's throttled rate for the rest of the daily cycle, then the allowance refills. You do not lose your connection and you do not have to buy anything. Most providers do not tell you, so the first sign is usually that a video stops loading. Roamless sends you a notification in the app when you reach 3GB, and you can stay at 1 Mbps or switch to Credits or a Data Plan at full speed until the reset.
Does unused data roll over on an unlimited plan?
No. A daily allowance is use it or lose it, and an unused day does not add to tomorrow.
