Most trips to Belgium start in Brussels and spread out by train: Bruges, Ghent and Antwerp are each under an hour away. For 15 days, Airalo asks $42, Saily $48.99 and Holafly $50.50. For a month, $71.50, $71.99 and $73.90. Ubigi is cheaper at $34 and $55 for a fixed amount at full speed. Ringo Light charges $12.99 for 2 weeks and $21.99 for 30 days, one payment each, nothing renews.
Read what unlimited means before you pick. Airalo gives 3 GB a day at full speed, then 1 Mbps. Saily gives 5 GB a day, Nomad 2 GB. Ubigi gives 30 GB for 15 days or 60 GB for the month, then 2 Mbps. Holafly states no daily cap for your own phone and limits sharing to 1 GB a day. Ringo Light has no speed cap: the 2 weeks starts with 10 GB and the 30 days with 20 GB, and when you have used 80% we add 10 GB once and charge the $12.99 top-up. A heavy two weeks with us costs $25.98, still under Ubigi's $34 for 15 days; a heavy month costs $34.98, under every rival for the month.
For a short trip, Ringo Light sells no 3-day or 7-day plan. Airalo sells 3 days of unlimited at $9.50, the cheapest here, and Ubigi a week with 20 GB at full speed for $19. Our 2 weeks at $12.99 still costs less than any rival's week.
Belgium has three big networks: Proximus, Orange Belgium and Telenet, which also runs BASE. All three cover the cities, the motorways and the train lines with 4G and 5G. Signal thins in the deep valleys of the Ardennes, around Dinant and Bouillon. Holafly is the only brand here that names all three; Airalo rides Telenet, Nomad Proximus and Orange, Ubigi Orange and Telenet.
If your phone plan is from another EU country, you roam here at home prices within a fair use limit, and you may not need a travel eSIM at all. Travellers from the US, the UK, Canada or Australia usually pay a daily roaming fee, and that is where a travel eSIM saves money.
Ubigi, $12 for 10 GB. The cheapest 10 GB, on Orange and Telenet, no app needed. 25 GB for 30 days at $21.
Airalo, $13 for 10 GB. Its Belganet plan on Telenet, 20 GB for $20, buckets from $4 for 1 GB.
Nomad, $16 for 10 GB. 20 GB for $20 on Proximus and Orange with 5G.
Saily, $16.99 for 10 GB. 20 GB at $25.99. Its listing is from June; saily.com would not load for us.
Ringo Light, no buckets. Our 2 weeks starts with 10 GB for $12.99 and our 30 days with 20 GB for $21.99. For 10 GB that lasts a month, Ubigi at $12 is the better buy, and Airalo's and Nomad's 20 GB at $20 both cost less than our month. We would rather you read that here than at checkout.
Ringo Light is our own data eSIM, sold to fund the full Ringo, one plan that works everywhere with your own number ported onto it. For Belgium it sells two trips, both unlimited data at full speed with no speed cap: 2 weeks at $12.99, starting with 10 GB, and 30 days at $21.99, starting with 20 GB. Each adds 10 GB once at 80%, charged at $12.99. One payment, nothing renews. The eSIM arrives by email in seconds and installs in one scan, no app.

You need your own number to keep ringing. None of these travel plans does that. The full Ringo, which Ringo Light funds, ports the number you have.
What to do in Belgium, and what your phone needs for it. Eight places most first trips include, from the Grand-Place to the Menin Gate, with the one thing your data does for you at each. Most are an hour or less by train from Brussels, and all have good 4G and 5G.
The Grand-Place, Brussels. The old market square, ringed by gilded guildhouses and the Gothic town hall, and on the UNESCO list. Come back after dark, when the facades are lit. Brussels signs switch between French and Dutch. Camera translation reads menus in both.
The Atomium, Brussels. Nine steel spheres built for the 1958 World Fair, with exhibitions inside and a view over the city from the top sphere. Metro line 6 runs to Heysel. Tap your contactless card or phone at the gate, then book your Atomium time slot on the phone.
The Rozenhoedkaai and the Belfry, Bruges. The canal corner with the Belfry behind it is the picture of Bruges. Climb the 366 steps of the Belfry, or take a boat along the canals. Bruges is about an hour from Brussels by train. The SNCB app sells the ticket and shows the platform.
Graslei and the three towers, Ghent. Medieval guildhouses along the river Leie under the towers of St Nicholas, the Belfry and St Bavo's, home of the Ghent Altarpiece. The Gravensteen castle is a short walk away. The centre is closed to cars. The De Lijn app sells tram tickets for the ride from Gent-Sint-Pieters station.
Antwerp Central Station, Antwerp. A stone hall under a glass and iron dome, finished in 1905, often called one of the most beautiful stations in the world. The diamond district starts next door. Trains to the Netherlands leave from here. Check live platforms and delays in the SNCB app.
The Grote Markt and the Oude Markt, Leuven. A university town under half an hour from Brussels, with a lace-like Gothic town hall and the Oude Markt, a square lined with bars end to end. Most bars and cafés take cards and phone wallets; keep a little cash for the smallest ones.
Dinant and the citadel, Dinant, on the Meuse. An onion-domed church at the foot of a cliff, with the citadel on top and the river in front. Adolphe Sax, who invented the saxophone, was born here. Signal thins in the Ardennes valleys. Save the map offline before you kayak the Lesse or walk the hills.
The Menin Gate, Ypres. A memorial arch carved with the names of more than 54,000 Commonwealth soldiers missing in the First World War. The Last Post sounds under it every evening at 8 pm. Search a family name in the Commonwealth War Graves Commission database before you go, and find the panel on your phone.
We priced Airalo, Holafly, Saily, Nomad, Ubigi and Ringo Light for Belgium on 28 September 2026, all on the same day, in US dollars. Each rival's price comes from its own website where it showed dollars, otherwise from an esimdb.com listing, and every source and its date is listed below. Ringo Light's prices come from the catalogue our checkout charges.
We compare the trips people actually book: a week, two weeks and a month of unlimited data, and a 10 GB bucket. We read each brand's fair use and speed rules and quote them as the brands state them. We did not run speed tests, so this page makes no speed claims for any brand.
Ringo Light is our own product. We put it in the table on the same terms as everyone else, and where a rival is the better buy the page says so.
Left out: Maya Mobile, we could not read its own prices for this country on the day, so it stays out rather than being guessed.

Airalo rides Telenet, Nomad Proximus and Orange, Ubigi Orange and Telenet, and Holafly all three. Saily does not name its network on its listing. All of them cover Brussels, Bruges, Ghent, Antwerp and the train lines between them.
Every brand has a limit somewhere. Airalo slows you after 3 GB a day, Saily after 5 GB, Nomad after 2 GB, Ubigi after its fixed full-speed amount. Holafly states no daily cap for your own phone. Ringo Light has no speed cap: it starts with 10 or 20 GB and adds 10 GB once at 80%, charged.
If your home plan is from an EU country, roaming in Belgium is usually included at home prices, within a fair use limit. Travellers from the US, the UK, Canada or Australia usually pay a daily roaming fee, and that is where a travel eSIM saves money. A Belgian prepaid SIM from a shop has to be registered with an ID before it works.
