Most travellers buy too much data because they are afraid of running out mid-trip, and then pay for gigabytes that expire untouched. This tool looks for the middle.
8 GB
Около 0,9 GB на ден за 7 дни, плюс 15% резерв за по-натоварените дни.

Four baseline daily levels are combined with the habits you tick — maps open most of the day, video every evening, hotspot shared with a travel partner — then multiplied by your days with 15% headroom for the heavier days.
- Navigation costs around 150MB a day in bursts
- Video at 1080p costs roughly 1.8GB an hour — more than everything else combined
- Automatic photo backup is the usage people forget to count
If you want a number from your own usage
Open your phone's data usage screen, reset the counter before your next trip and read it when you get home. That figure beats any average, including ours.
The output is an estimate, not a measurement of you
This tool does not read anything off your phone. It does not know how many hours of video you watch, and it does not know whether the hotel you booked has Wi-Fi that actually works. What it does is take the usage pattern you selected, multiply it by your days, and leave a little room for the days that go sideways. The result is a sensible starting point, not a measurement of you.
The distinction matters because it changes how you should use the figure. Treated as a measurement, you buy it and stop thinking. Treated as an estimate, you do two more useful things: check real usage during the first days of the trip, and know in advance what you would do if it runs short.
Frequent travellers notice their own consumption is fairly stable from trip to trip. If you have ever written it down, that number beats anyone's average, ours included. Averages exist for people who do not yet have their own data, not for people who do.
Why gut feel misses in both directions
Most people guess high because they are afraid of running out. The fear is rational — running out while trying to find your way back to a hotel in an unfamiliar city is not an experience anyone wants twice. But over-buying means paying for gigabytes that expire with the plan untouched.
Interestingly, some people guess low for the opposite reason. They reason from home usage, where Wi-Fi is always present, and forget that on a trip everything that used to sit on Wi-Fi moves onto mobile data: maps while walking, looking up restaurants, checking transport times, sending photos home.
Both mistakes have the same root: estimating from feeling instead of from something countable. The next section is about converting the feeling into a number, which takes a few minutes and can be done before you leave.
Getting your own number from the phone in your hand
- 1Open the data usage screenEvery OS has one, though the menu name and location differ by manufacturer and version. Search the settings app for data or network usage and look for the screen showing a running total alongside a per-app list.
- 2See which apps dominated the last monthThe list is usually more surprising than expected, and one or two apps normally account for over half. Knowing which they are lets you control the right thing instead of economising on everything equally.
- 3Reset the counter before you travelIf your handset lets you reset it, do so on departure day. The figure you read on your return is then that trip's real consumption, with no back-calculation needed.
- 4Divide by the days to get your own daily averageThat number is what you should start from next time, with a little added when the coming trip involves more navigation or long travel days.
- 5Write it somewhere you will find itNote it with the country and the type of trip, because a hiking trip and a city conference trip consume very differently.
What genuinely eats data, and what people fear needlessly
Ranking helps more than blanket economising. High-resolution video sits at the top of the list every time, and by a wide margin. Messaging and checking email sit at the bottom, low enough to ignore. Control only the top of the list and you capture nearly all of the benefit without spending the trip feeling restricted.
| Activity | Weight on your data | What to do about it |
|---|---|---|
| Streaming video at high resolution | The heaviest by far, easily more than everything else combined | Lower the quality in the app's settings, or download over Wi-Fi in advance |
| Long video calls | Heavy, comparable to streaming | If seeing faces is not the point, voice-only is dramatically lighter |
| Automatic photo and video backup | Heavy and invisible, because it runs in the background without asking | Set it to Wi-Fi only for the whole trip |
| Scrolling social feeds that autoplay video | Moderate to heavy, depending how long you scroll | Turn off autoplay inside that app's settings |
| Maps and navigation | Moderate, but daily use makes it accumulate | Download the offline map for your city before you go |
| Search, reading pages, checking reviews | Малко | Leave it alone; restricting it buys discomfort, not gigabytes |
| Messaging and plain email | Very light | Not worth a thought, except for video sent inside chats |
Ranked by real impact, so you only control what is worth controlling
The Wi-Fi you are counting on versus the Wi-Fi you get
A lot of data plans fail on the Wi-Fi assumption rather than on arithmetic. People assume the accommodation has Wi-Fi, buy little data, and discover the signal does not reach the room, or that it does but is too slow to use, or that it requires re-accepting terms every hour.
The safer approach is to plan with Wi-Fi as a bonus rather than as the foundation. Buy enough data for the hours you spend outside your accommodation each day, and working Wi-Fi becomes upside. If it fails, the trip carries on unchanged.
One more thing to anticipate: public Wi-Fi in cafés and airports usually puts a terms page in front of you, and those pages behave poorly on handsets with strict privacy settings. If you regularly find yourself connected but unable to load anything, that is the terms page refusing to appear — not a problem with your data plan.
Settings that cut usage without spoiling the trip
Good data saving is saving you never notice. The list below runs from the highest result per unit of inconvenience. For most people the first three, done before departure, are enough.
- Set photo and video backup to Wi-Fi only
- Download offline maps for your destination before leaving home
- Download music, podcasts and anything you plan to watch over Wi-Fi in advance
- Turn off autoplay in whichever social apps you open most
- Stop automatic app updates over mobile data
- Drop the default video quality one step in the apps you actually watch
- Check no large work-file sync is running in the background
Notice that none of these ask you to stop using the internet. Saving that leaves you afraid to open a map when lost is not saving at all; it just moves the cost from money to stress.
Buying tight versus buying loose
| Approach | What you gain | What it actually costs |
|---|---|---|
| Buy exactly what the estimate says | You do not overpay, and you learn your real number afterwards | If the estimate was low, you deal with it mid-trip at a possibly awkward moment |
| Buy one size up | You stop thinking about data for the rest of the trip | You pay for gigabytes that may expire unused |
| Start small and top up if needed | Closest to paying for what you actually use | Only works on plans that support top-ups, which has to be checked before buying |
| Choose an unlimited plan | No volume guessing at all | Nearly all have a daily full-speed ceiling, so the question becomes whether that ceiling fits your day |
Four approaches people genuinely use, and what each one trades away
None is right for everyone. A trip inside a large city where buying more is easy carries less risk than one heading somewhere remote, where topping up mid-trip may be impossible precisely because you have no connection to buy with. That, more than price, is the strong argument for buying a size up.
Unlimited does not mean you can stop thinking
A plan labelled unlimited does remove the how-many-gigabytes question, but nearly all of them carry a daily full-speed condition. Once the stated amount is used, speed is reduced either until the day rolls over or until the plan ends, depending on the terms. The question does not disappear; it changes shape from how much for the whole trip to whether the daily ceiling covers your day.
Check two things on the plan page before buying: what the daily full-speed amount is, and whether full speed returns at the day boundary once exceeded. Both vary by supplier and by plan, so do not carry an assumption over from the last one you used.
Groups, and sharing by hotspot
Sharing a hotspot with travel companions changes the sum materially, because their usage is your usage. If one of them watches video for a two-hour train ride, all of that comes out of your plan. Have the conversation before agreeing to share, not after.
Hotspot sharing also drains the battery hard. On a day spent walking, being everyone's hotspot can leave your phone dead before evening — a bigger problem than data, since a dead phone has no map and no travel tickets either.
If the group will not be together all day, individual plans usually cause less friction. If you walk together and one person carries a phone they can keep charged, sharing works well. Decide from how the trip will actually run, not from price alone.
Check as you go, and adjust while there is still time
Discovering on day three that the data will not last is far easier to fix than discovering it on the last day. Look at the usage figure on the evening of day two or three and compare, roughly, what fraction of the allowance is gone against what fraction of the trip is gone. If the two are close, the plan is holding.
- Open the data usage screen on the evening of day two
- Compare the fraction used against the fraction of days elapsed
- If you are ahead of pace, find the responsible app in the per-app list
- Adjust that one app: lower its quality or stop its background sync
- Check again two days later to see whether the change worked
If it is clearly going to run short, act while you still have data left rather than waiting for zero. Buying more or topping up needs a connection to complete the transaction, so keeping a little in reserve means keeping your options open.
Често задавани въпроси
Can I buy exactly the number this page gives, or should I add more?+
Use it as a starting point, then adjust for the two things it cannot know. First, whether you will really have usable Wi-Fi at your accommodation — if unsure, round up. Second, whether you are heading somewhere that makes buying more difficult; if so, round up as well. In a large city with reliable accommodation Wi-Fi, buying to the number is reasonable.
Why does the result include a small buffer?+
Because real trips have days that go off plan: maps open all day because a train was cancelled, a longer call home than usual, accommodation Wi-Fi that does not work. A small buffer costs less than solving the problem when the data runs out somewhere unfamiliar.
If I under-buy, can I top up during the trip?+
Only on plans that state they support top-ups, which the plan page tells you. Check that before buying if you intend to buy tight. If a plan cannot be topped up you can still buy another and install it as a second profile — but that needs a connection to complete, so act before you hit zero.
How much extra should I add if I am sharing a hotspot?+
There is no fixed figure, because it depends on what your companions do. If they check maps and chat, the addition is small; if they watch video in transit, it can exceed your own usage. The direct approach is to ask what they normally do and add accordingly — or give everyone their own plan if the group will split up during the day.
Does an unlimited plan make this page unnecessary?+
Not quite, because nearly all unlimited plans have a daily full-speed ceiling. The question shifts from how many gigabytes to whether that daily ceiling covers your day — which still requires estimating daily use. The number from this page remains useful for comparing against the daily ceiling of the plan you are looking at.
Why did my real usage differ so much from this estimate?+
Because real usage depends on things this page cannot see: background photo backup, the quality of your accommodation Wi-Fi, how many hours you spend out of the room, and video habits that vary enormously between people. The way to get a better number is to record this trip's total and use it as the base next time, which always beats an average.
Често задавани въпроси
Can I buy less and top up later?+
Only on plans marked as top-up capable, which the plan page states outright. If a plan cannot be topped up you can still buy another and install it as a second profile.
Does an unlimited plan remove the question?+
It removes the guessing, but nearly every unlimited plan has a daily full-speed ceiling and throttles after it. The question becomes whether that daily ceiling fits your day.
Why does the result add 15%?+
Real trips have days that go off plan: navigation all day, a long video call home, hotel Wi-Fi that does not work. A small buffer is cheaper than fixing it when the data runs out.
