The short answer
Six travel eSIMs sell a Belgium plan and get most of the traffic for this search. I priced all six on the same day, for a weekend in Brussels, two weeks by train between Brussels, Bruges, Ghent and Antwerp, and a month, and read the fine print on unlimited. Here is where each one wins.
Unlimited data at full speed for 2 weeks at $14.99 or 30 days at $26.99, nothing renews. Airalo asks $42 for 15 days and $71.50 for the month.
3 days of unlimited at $9.50 and 20 GB for 30 days at $20, on Telenet.
10 GB for 30 days at $12, on Orange and Telenet, installed by QR code.
Days, not gigabytes, no daily cap stated for your own phone, on Proximus, Orange and Telenet. $27.50 for a week.
Prices read on 11 November 2026: Airalo, Holafly, Saily, Nomad, Ubigi on their own sites or listings, Ringo Light from its catalogue. All in US dollars unless stated. Treat every number as a snapshot.

The prices, charted
US dollars, 11 November 2026. The rivals sell 15 days, Ringo Light 2 weeks. Ubigi's 15 days is 30 GB at full speed, then 2 Mbps. Nomad sells no 15-day unlimited.
The 30-day plan at each brand. Ubigi's month is 60 GB at full speed, then 2 Mbps. Nomad sells no 30-day unlimited.
Holafly sells no buckets. Ringo Light sells no bucket either: its 2 weeks is unlimited, so it lasts 2 weeks, not 30 days.

Want to keep your own number abroad?
That is the full Ringo service: one plan that works everywhere, with your own number included.
It is a separate product from Ringo Light and it is still being built, so it is not on sale yet. Join the waitlist to hear when it opens.
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.
If you want unlimited for two weeks or a month: Ringo Light
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 $14.99 for 2 weeks and $26.99 for 30 days, 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 is unlimited data at full speed for 2 weeks or 30 days.
For a short trip, Ringo Light sells 3 days of unlimited data at $8.99, and no 7-day plan. Airalo sells 3 days of unlimited at $9.50 and Ubigi a week with 20 GB at full speed for $19. I still count Ringo Light 2 weeks at $14.99 as cheaper than any rival's week.
Networks and roaming in Belgium
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. I read Holafly as 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 I would check that before you buy, because 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.
If you want a data bucket: Ubigi or Airalo
- 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, 10 GB for $13.
- 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.
- ✓Ringo Light, no buckets. Ringo Light 2 weeks is unlimited for $14.99 and its 30 days unlimited for $26.99. 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 Ringo Light month. I would rather you read that here than at checkout.
What Ringo Light is
Ringo Light is Ringo's own data eSIM, sold to fund the full Ringo, one plan that works everywhere with your own number ported onto it. I write for Ringo, so I tell you which rival wins a row. For Belgium it sells three trips, all unlimited data at full speed: 3 days at $8.99, 2 weeks at $14.99 and 30 days at $26.99. Nothing renews. The eSIM arrives by email in seconds and installs in one scan, no app.
The card to buy it is further up this page, just after the side-by-side table.
Pick by trip
Ringo Light unlimited, 3 days, $8.99, against $9.50 at Airalo; its 2 weeks is $14.99 if the trip might run longer.
Ringo Light unlimited, 2 weeks, $14.99, less than any rival charges for one week.
Ubigi 10 GB for 30 days at $12.
Ringo Light unlimited, 30 days, $26.99. Holafly at $73.90 if you want all three Belgian networks.
None of these travel plans does that. The full Ringo, which Ringo Light funds, ports the number you have.

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.
