A fixed data eSIM is a prepaid plan with a set amount of data and a validity period, such as 5 GB for 30 days. The plan ends when you have used the data or the days are over, whichever comes first. Spidot sells fixed data plans for 160 countries and Europe.

A practical guide to fixed data eSIM plans
A fixed data plan is the simplest way to buy mobile data for a trip: you choose an amount of data and a number of days, pay once, and use the data while you are away. Prices for fixed data plans start from $2.90, and the right size depends far more on how you use your phone than on where you are going.
This guide explains how fixed data plans behave in day-to-day use, how to estimate the amount you need, how they compare with the other Spidot plan types and with roaming or a local SIM, and what to do if your plans change during the trip.
How a fixed data plan works in practice
Every fixed data plan has two limits: an amount of data and a validity period. You can use the data at any pace you like within those limits. Use a lot on the first day and less afterwards, or spread it evenly; the plan does not care, as long as you stay within the total and the days.
The plan ends at whichever limit you reach first. If you use all the data before the last day, mobile data on the Spidot line stops. If the days run out and you still have data left, the remaining data is no longer usable. That second case is the one most travellers want to avoid, which is why choosing a sensible size matters more than choosing a large one.
The validity period of each plan is shown before you buy. Read the plan details if you want to know exactly how the days are counted, and keep an eye on the days left in My eSIMs during the trip.
What you get and what you do not
A fixed data plan is data only. It does not come with a local phone number, call minutes or SMS. Your own SIM stays in your phone, so your usual number keeps working for calls and texts at your home operator's rates, while the Spidot eSIM handles mobile data. Messaging and calling apps work over that data as normal.
Who fixed data suits
Fixed data is a good default for most single trips with known dates. It tends to fit well if any of these describe you:
- You are going on one trip, such as a holiday, a city break or a business trip, and you know roughly when you leave and return.
- You mostly use your phone for maps, messages, email, social media and looking things up, rather than streaming for hours a day.
- You have Wi-Fi at your hotel, flat or office for the heavy things like large downloads, backups and long video calls.
- You like knowing the total cost before you travel, with nothing that can grow while you are away.
- You travel for a week or more and want to avoid paying for unlimited data you are unlikely to use.
How to estimate how much data you need
The easiest starting point is your own phone. Most phones show how much mobile data you used in the last month or billing period, and some show it per app. Divide that by the number of days to get a daily figure, then adjust for the trip: you may use more for maps and translations, and less for streaming if you have hotel Wi-Fi.
If you have no history to go on, the rough figures below can help. They are approximate and vary a lot with the app, the video quality, the network and your settings, so treat them as a guide rather than a promise.
- Messages and email (text, a few photos): a few megabytes to a few tens of megabytes a day.
- Maps and navigation: often in the region of tens of megabytes per hour of active use; more if you browse satellite views or load large areas.
- Web browsing and social media: roughly 50–200 MB per hour, rising quickly when feeds autoplay videos.
- Music streaming: very roughly 50–150 MB per hour, depending on quality.
- Voice calls over an app: in the region of 0.5–1 MB per minute.
- Video calls: often several hundred megabytes per hour, sometimes more.
- Video streaming: from under 1 GB per hour at standard quality to several GB per hour in high definition.
Three rough example trips
These examples are illustrations only, not recommendations for a specific plan. A light user on a week-long city break who uses maps, messages, a little social media and some looking things up might use around 1 GB over the week, which matches the rule of thumb in the questions on this page.
A moderate user on a two-week holiday who also posts photos, makes a few short video calls and uses a ride-hailing or transport app every day might use something like 3–6 GB in total.
A heavy user who works remotely, joins video meetings on mobile data or shares their connection with a laptop can use several gigabytes in a single day. For that pattern, an unlimited plan or a large fixed plan is usually a better fit.
Leave a margin, but not too much
Navigation in an unfamiliar place, a delayed train or a last-minute booking can all add data you did not plan for. A small margin of perhaps 20–30% above your estimate is sensible. You do not need to double it, because you can add more data to the same eSIM if you run low.
Matching the days to your trip
Choose a validity period that covers your whole stay, including travel days. It is easy to forget the day you arrive and the day you leave, which are often the days you need data most: finding your way from the airport, checking a booking, ordering a taxi or messaging the person collecting you.
If your trip falls between two validity periods, the longer one is usually the safer choice. Running out of days on your last morning is more inconvenient than having a few spare days at the end.
When you run low or your plans change
Check your balance from time to time in My eSIMs. Your phone's own data counter is only a rough guide; the balance on your eSIM is the one that counts. Our guide on how much data is left explains why the two numbers can differ.
If your balance is lower than you expected halfway through the trip, you have two options: reduce your usage (see the tips below) or top up. Top-ups are added to the eSIM you already have, so there is nothing new to install and no new QR code to scan.
Ways to make your data last longer
- Download offline maps for the cities and regions you are visiting while you are on Wi-Fi.
- Turn off video autoplay in social media apps and set streaming apps to a lower quality on mobile data.
- Stop photo and cloud backups from running over mobile data; let them run on Wi-Fi instead.
- Download playlists, podcasts and films before you leave home or at the hotel.
- Check which apps use the most data in your phone's settings and restrict background data for the ones you do not need.
Fixed data compared with the other plan types
Spidot sells four plan types. They solve different problems, so the right choice depends on your trip rather than on which one sounds most generous.
Fixed data or unlimited
An unlimited plan is priced by the day, has no data cap and may slow down after heavy daily use. It suits short trips where you use a lot of data every day. For a longer trip with moderate use, a fixed data plan usually costs less, because you only pay for the data you expect to use rather than for the freedom to use a great deal.
Fixed data or no-expiry
A no-expiry plan has no validity period, so unused data stays on the eSIM for your next trip. If you travel to the same area several times a year, that can be more convenient than buying a new fixed plan each time. For a single trip with known dates, a fixed plan is simpler.
Fixed data or data + calls
A data + calls plan adds call minutes and SMS to the data. Most travellers do not need this, because messaging and calling apps work over data and your own number keeps working for incoming calls and texts. It is worth considering only if you need to call or text without an app.
Fixed data compared with roaming and local SIMs
A fixed data eSIM sits between two familiar options. Each has its own trade-offs, and none is right for every traveller.
Roaming with your home operator
Roaming is the easiest option, because there is nothing to buy or install. Whether it is good value depends entirely on your operator and your destination. Some plans include roaming in certain countries; for example, many people with EU SIM cards can use their allowance across the EU under the "Roam like at Home" rules, although these rules do not apply to everyone or everywhere. Others charge daily fees or per-megabyte rates. A fixed data eSIM gives you a known price up front, which is easy to compare with your operator's offer before you go.
A local SIM card
A local SIM can be good value for long stays and usually comes with a local number. The trade-offs are practical: you need to find a shop on arrival, there may be identity checks, and you have to remove your own SIM unless your phone has two slots. A fixed data eSIM can be bought and installed before you fly, so you have data as soon as you land and your own SIM stays in place.
Getting ready before you travel
A little preparation at home makes the first hour of the trip much easier. You need an internet connection to install an eSIM, so do it while you are still on your home Wi-Fi.
- Check your phone: it must support eSIM and be carrier-unlocked. Dialling *#06# shows an EID on phones that support eSIM.
- Buy your plan and install it from the QR code we email you. There are step-by-step guides for iPhone, Samsung and Pixel.
- Give the new line a clear label, such as Travel, and keep your own SIM as the default for calls and texts.
- Make sure data roaming stays off for your own SIM, so your home operator does not charge you for data.
- Download offline maps and anything else you will need on the journey.
On arrival
When you land, choose the Spidot line for mobile data and turn on data roaming for that line. The data roaming guide shows where the setting is on each type of phone. It can take a minute or two for the phone to find a network, especially straight after switching off flight mode.
If you have signal but no data, check that the Spidot line is selected for mobile data and that roaming is on for it, then restart the phone. Those two settings solve most problems on the first day.
Several countries on one trip
A fixed data plan for one country works in that country. If your trip crosses borders, a regional plan is usually easier than buying a separate plan for each stop. The Europe plan covers many European countries on one eSIM, which suits rail journeys, road trips and cruises with several ports.
For trips to a single country, start from that country's page, for example France, Italy, Spain or the United Kingdom. You can see every destination on the destinations page and compare plan sizes and prices on the prices page.
Sharing your data with other devices
Most phones can share their mobile data with a laptop or tablet through the personal hotspot feature. Anything you share comes out of your plan's data allowance, and laptops often use far more data than phones because they run updates, cloud sync and full-size web pages in the background.
If you expect to tether a laptop regularly, either choose a larger fixed plan or look at whether an unlimited plan suits the length of your trip. Before tethering, pause automatic updates and cloud backups on the laptop, or set your hotspot as a metered connection if your laptop supports it.
