Data & speed
Real-world speed, FUP, and checking your remaining data.
This section explains data volume and speed while using an eSIM abroad — from the factors that genuinely affect real-world speed, to checking remaining data, through to what happens when data runs out before the validity period ends. Nothing here promises a fixed speed or volume figure, since actual results depend on several factors outside the plan alone.
If you are looking for basic network setup, the network and settings category answers that more directly. This page suits anyone whose settings are already correct but who is wondering about actual speed or remaining data volume.
What genuinely affects real-world speed
Real-world speed depends on several factors together: local network density in that area, how many other users share the same network at the same time, buildings or terrain blocking signal, and which network generation the device is connected to at that moment. No fixed speed figure is stated here, since these factors change constantly and differ from place to place.
If you want a general sense of the network in the destination country before travelling, the most direct approach is to look at coverage information published by the local network operator itself, rather than guessing from experience in a different country.
Checking remaining data
| Channel | How to check |
|---|---|
| Orders page in your account (if you have one) | Sign in and open the relevant order to see the latest usage status |
| The device's own network settings menu | Most smartphones can show data used per SIM separately, built into the settings |
| Notification email (if the system sends one) | Some plans send an email as data nears exhaustion — check the inbox including the spam folder |
Channels for checking remaining data
What to do if data runs out before the period ends
If the data volume bought runs out before the plan's own end date, the most straightforward options are topping up if that plan supports it, or buying a separate new plan for the remaining time. Detail on top-up terms is covered specifically in the top-up category.
Some plan types may throttle speed rather than cutting the connection outright once the stated data volume is used, depending on that plan's own terms — check what is stated on your specific plan's page to know which type it is, so there is no surprise when that point is actually reached.
Saving data while travelling
- Download offline maps in advance before setting off
- Turn off automatic app updates while on mobile data
- Use accommodation or venue Wi-Fi when available instead of mobile data
- Lower streaming video quality when not connected to Wi-Fi
- Turn off automatic photo cloud-sync if not essential
Estimating data needs before buying
If you are unsure how much data volume to buy, our data calculator tool helps estimate a rough figure from the usage habits you describe, such as how often you use navigation or whether you watch video during the day. The figure produced is only an estimate to help with the decision, not a guaranteed exact match to everyone's actual usage.
FAQ
Will the speed be the same as at home?+
Not necessarily, since it depends on the local network and actual conditions in that area at the time, which differ from the network you are used to at home.
Can the remaining data figure ever be inaccurate?+
There can be a small discrepancy between the figure the device counts itself and the figure on the orders page, since the two do not count in exactly the same way — treat the orders page figure as the primary reference.
Why does a speed-test app give a different number every time?+
Network speed changes constantly with the number of users and conditions at that moment, so a speed-test app result only captures a brief snapshot, not a constant value.
Will speed differ between a big city and a rural area?+
Generally a big city tends to have denser network coverage than a rural area, though this is not an absolute rule — it depends on the actual local network operator in that specific area.
If I top up, does throttled speed return to normal?+
It depends on that plan's own terms — some plans return to normal speed immediately after topping up, others may work differently. Check the plan's page or the top-up category for clarity.
Does heavy use early in the trip affect data left later in the trip?+
Yes, it does, since the data volume bought is one shared pool used across the whole plan period, not automatically divided into a daily allowance. Planning roughly ahead of time helps if you want it to last the whole trip.
Common questions in this section
The connection is slower than expected+
The usual causes are: your full-speed allowance is used up (FUP), you are in a congested area such as a station at rush hour, or the phone is on 4G where 5G does not reach. Check usage first, then try moving or selecting a network manually.
What does FUP mean?+
A fair usage policy is a cap on full-speed data per day or per cycle. After the cap, speed is reduced but you stay connected. Almost every 'unlimited' travel plan on the market has one; our plan pages state the threshold and the throttled speed explicitly.
Is an unlimited plan really unlimited?+
Unlimited in total volume, but speed-limited after a daily threshold — for example 2GB at full speed per day, then about 512 kbps until the next reset. If you stream a lot every day, compare the daily thresholds rather than the word 'unlimited'.
What time does a daily plan reset?+
Our daily plans reset at 00:00 destination local time — not your home time and not the hour you activated. If you land late at night, that day's allowance has only a short window before it resets.
How do I check my remaining data?+
If your plan reports usage, the remaining figure appears under My eSIM. It comes from the supplier and typically lags 15–60 minutes. Your phone's own counter measures from its last reset, so the two rarely match exactly.
How can I use less data while travelling?+
Download offline maps and playlists while on Wi-Fi, turn off autoplay video in social apps, disable automatic photo backup, and switch on the system data saver. Those four typically cut usage by more than half.
How much data does photo backup use?+
It is usually the single biggest background consumer. Modern phone photos run 3–6MB each and 4K video around 350MB per minute. Set backups to Wi-Fi only for the duration of your trip.
How much data does a video call use?+
A standard-definition video call typically runs 200–400MB per hour; high-definition work meetings can reach about 1GB per hour. If you have daily meetings, pick a daily plan with a high threshold or an unlimited plan.
Why did my data slow down after a few days?+
The most common cause is that you have used the full-speed allowance. Plans with a fair-use policy reduce speed after the stated threshold. Check your usage first; if you are below it, work through the speed troubleshooting steps, since it may be the network you are attached to.
My data disappeared unusually fast. What should I check?+
Look at per-app usage first. The usual culprits are automatic photo and video backup, app updates, and autoplaying video in social apps. All three can be switched off in settings and usually recover the most data with the least disruption.
How much should I trust a speed test?+
A test describes that spot at that moment only. Results move with the number of users, distance from the mast and the priority roaming users receive, and the test itself consumes your allowance. Run one to confirm the connection works, then judge by real use.
Do apps use data when I am not using them?+
Yes. Many apps sync, download updates and back up photos in the background, which is a common reason an allowance disappears faster than expected. Turn off background refresh, disable automatic photo backup on mobile data, and set app updates to Wi-Fi only.
Why is it slower in the evening than during the day?+
More people share the same network in the evening, so the capacity per user falls. That is how mobile networks behave everywhere; it is not a fault of the plan.
Is a hotspot slower than using the phone directly?+
The network speed is the same, but it is shared between the attached devices, and relaying over Wi-Fi adds a little latency.
