What travelers ask us most?
Yes. The Europe plan covers Belgium and 48 other countries, including France, the Netherlands, Germany, Luxembourg, and the UK, and your phone switches networks by itself at the border. Choose it over a Belgium-only plan if a train to Paris, Amsterdam, Cologne, or London is on the cards. Details in does a region plan cover every country in it?
In Belgium your plan connects to Proximus, Orange, or BASE, with 5G in the cities and 4G LTE elsewhere. Your phone joins the network automatically once the plan is switched on. If it hasn't connected a minute after landing, work through the no-signal checklist.
Only on the Europe plan, which covers the UK; a Belgium-only plan stops at the border. If you're already in Belgium on a Belgium plan, add a UK plan to the same eSIM before you board.
Yes, the whole country, with 5G in the cities and 4G on the trains and the coast tram. The only thin patch is the Ardennes forests in the south-east.
It depends on how much data you want and how many days you're staying. A fixed plan costs less overall; an unlimited plan (5 GB a day at full speed, then slower) works out to a lower daily rate the longer you stay. Every current option and price is in the plan selector at the top of this page.
In the app: open My plans, choose your Belgium plan, and tap Top up. The extra data lands on the same eSIM within a few seconds, with nothing new to add or scan. Full steps are in topping up data without reinstalling the eSIM.
Weeks ahead. The plan's days don't start until you turn it on and connect, so a plan bought a month before departure is still complete when you land. Plans need to be activated within 90 days of purchase. See what plan validity means and when it starts.
If it's eSIM-compatible and carrier-unlocked, yes, which covers most phones sold since 2019. The one-minute check for iPhone, Android, and Samsung is in is my phone eSIM compatible?

Belgium eSIM for Brussels, Bruges, and trains to four countries
Set it up before you fly. It's live the moment you land, nothing to check, nothing to remember.

Belgium is a country you cross by train in two hours and leave by train as fast, to Paris, Amsterdam, Cologne, or London, which is why the plan question here is really a Europe question. The best eSIM for Belgium is the one that's working when you land at Brussels Airport, so the short train into the city is bought on the platform and the rest of the week is planned on board.
Below: how a Belgium plan works, how to set it up before you fly, what to expect in Brussels, Bruges, Ghent, and Antwerp, and why the Europe plan is usually the better buy.
Most travel eSIMs make you start over for every country, which in Europe means a new QR code every few days. KnowRoaming doesn't. You add the KnowRoaming eSIM, called KR.One, to your phone once, and from then on each trip is a plan you add to it: Belgium now, Portugal in the spring, the whole continent on a Europe plan when the itinerary gets ambitious. Nothing to scan again, nothing to delete when you get home.
The plan's days start when you turn it on and connect in Belgium, not at checkout. Buy it weeks ahead, add it at home, and a delayed flight costs you nothing. The full rule is in what plan validity means and when it starts.
Choose a fixed plan for a set amount of data at the lowest overall price, or an unlimited plan when you'd rather not count. Unlimited plans give you 5 GB a day at full speed, then a slower speed until the allowance resets the next day. If a fixed plan runs low, top up in the app and the extra data lands on the same eSIM.
See it in two minutes: Meet KR.One, iPhone setup with KR.One, or Samsung setup with KR.One.
Do this at home on Wi-Fi. It takes about a minute.
Before you leave
- Get the KnowRoaming app (available on iOS and Android) and choose your Belgium plan.
- Tap Add. First time on this phone? The app adds KR.One and your Belgium plan together. Already have KR.One? Only the plan is added, with nothing to scan.
- Leave data roaming off on the KnowRoaming line until you land, and turn it off on your home line too so it doesn't run up charges in the background. Steps are in turning off roaming on your home line.
When you land
- Turn the plan on in the app, then turn data roaming on for the KnowRoaming line. That setting lives in your phone, so the app can't flip it for you.
- Give the phone a minute to find the network. If nothing happens, turn airplane mode on for 30 seconds and off again.
Prefer a QR code? The checkout page and your confirmation email both carry one; scan it from your phone's settings. Every tap, by device, is in adding your eSIM on iPhone, adding your eSIM on Android, and adding your eSIM on Samsung, or watch the iPhone QR walkthrough or the Samsung QR walkthrough. Still no signal after landing? Work through the no-signal checklist.
Brussels Airport has a train straight to the city center in about half an hour; Charleroi, the low-cost airport, is an hour by bus. The SNCB app sells train tickets for the whole country and the STIB app covers Brussels' metro, trams, and buses, both easier to use with data than at a machine. Uber and Bolt run in Brussels.
Cards and phone wallets work almost everywhere, including on the trams. The Grand Place, the Sablon, and the comic-strip murals are the first walk; the museums, the Atomium, and the beer bars all sell or reserve online.
Bruges is an hour from Brussels by train, Ghent half that, Antwerp about 45 minutes; all three fit in a day each, and the trains run every half hour without a reservation. Bruges' canals and belfry fill by mid-morning in season, so the early train earns its keep. The coast tram runs the whole Belgian coast from De Panne to Knokke, and Ostend is the beach town.
Coverage is 5G in every city and 4G on the trains between them; Belgium is flat, dense, and well covered end to end.
Brussels is the hub: Paris in 1 hour 20 by high-speed train, Amsterdam in under two hours, Cologne in under two, London in two by Eurostar. Every one of those countries, and Luxembourg, is on the Europe plan, 49 countries on one plan, switching networks by itself at the border, the UK included. A Belgium-only plan stops at the border, so for any trip that takes one of those trains, the Europe plan is the better buy from the start. Read do I need a new plan for every country? for the detail.
Brewery visits, chocolate workshops, and the Christmas markets in Brussels, Bruges, and Liège all take reservations online, and the smaller breweries only open on set days. Tomorrowland in July and the Ghent Festival in the same month are the two events that fill the trains and the hotels; plan around them or for them.
The south-east of the country is the Ardennes: forested hills, river towns like Dinant and Bouillon, kayaking on the Lesse and the Semois, and Bastogne's war museums. Namur is the gateway by train; beyond it, the valleys are car and bike country, and the signal thins in the deeper folds of the forest on every network.
It's the one part of Belgium to treat like a mountain region: download the route, save the guesthouse number, and expect the phone to come back when you climb out of the valley.
Brussels is a city of short business trips and long meetings, and Belgian 5G handles video calls from a hotel room without trouble. For a stay of a week or more with calls and a laptop on the hotspot, an unlimited plan, with 5 GB a day at full speed, is the right buy; fixed plans suit a weekend. Both are on the plan selector at the top of this page.
Your plan connects to Proximus, Orange, or BASE, with 5G in Brussels, Antwerp, Ghent, Bruges, Liège, and the other cities and 4G LTE across the rest of the country. Your phone picks the network automatically once the plan is on; there is nothing to choose by hand.
The one gap to plan for is the Ardennes, in the south-east, where the forest valleys thin the signal on every network. Download maps before a hike.
Most phones sold since 2019 support eSIM, including iPhone XS and later and most Android flagships from the same window. Check yours before you add a plan; it takes a few seconds. On iPhone, go to Settings, General, About and look for an EID or Available SIM. On Android, go to Settings, Network & Internet, SIMs and look for an option to add an eSIM. On Samsung, dial *#06# and look for an EID.
Your phone also needs to be carrier-unlocked. If you're not sure, carrier-locked vs unlocked: how to tell shows you where to look.
Adding a Belgium plan doesn't touch your regular SIM. Calls and texts on your usual number keep working exactly as before. The new plan handles data while you're there, and most phones run both at once without you doing anything else. Bank codes and two-factor texts still arrive on your home number, as long as that line stays switched on.
For a European trip the real competition isn't another eSIM. It's your home carrier's roaming add-on, priced for a weekend and throttled by midweek; the SIM counter in arrivals, after the flight, with a queue; and café Wi-Fi, in a country where even the bus ticket is in an app. A Belgium plan added at home beats all three: one price agreed before you fly, live the second you land, and a Europe plan waiting if the trip grows.
