What to know about mobile data in Belgium
Belgium is in the EU roaming area and small enough that a border is never far: France, the Netherlands, Germany and Luxembourg are all an easy train ride away. 3G is gone. Proximus closed it at the end of 2024, the other operators followed in 2025, and no 3G network has been active since that summer. 2G is being kept for now, with operators and the regulator pointing to 2028 and 2029 for its end. Most visits are multi-country trips.
Before you go
- If Brussels is one stop between Paris and Amsterdam, a single-country plan will not last the day. Compare plans for the whole route.
- Taking the Eurostar to London? The UK is outside the EU roaming regime. Check that the United Kingdom is named in the plan.
- Near Maastricht, Lille or Aachen the phone may hold a neighbouring country's signal. That is harmless on a regional plan and a problem on a Belgium-only one.

Plan a route starting in BelgiumFrequently asked questions
What is the cheapest eSIM for Belgium?
On October 5, 2026, the cheapest plan we found was Yesim with 1 GB, 30 days at $3.00. The lowest price per gigabyte was aloSIM: 50 GB, 10 days at $25.00, which is $0.50/GB.
Is there an unlimited data eSIM for Belgium?
Yes. 7 of the providers we track sell unlimited plans for Belgium; the cheapest is Holafly at $3.90 for 1 day. Unlimited plans often slow down after a daily amount, so read the fair-use note on the provider page.
Which regional eSIM plans include Belgium?
26 of the 69 regional and global products we track list Belgium: Ubigi Europe, Nomad Europe (35 countries plan), Yesim Europe & UK, Holafly Europe, Saily Europe Unlimited (35 countries), Airalo EUconnect (European Union and United Kingdom), Saily Europe (34 countries), Airalo Eurolink.
Is a Belgium-only eSIM worth buying?
Only if you really stay in Belgium. The country is small and its neighbours are close, so the phone crosses into another network quickly, and a plan covering the countries on your route avoids losing data at each border.
Will my data work in the Channel Tunnel on the way to London?
The tunnel has mobile coverage, but that is not the limiting factor. What matters is whether your plan lists both France and the United Kingdom, because the UK is no longer in the EU roaming regime.
