Belgium eSIM
data from $1.99.

You step off the Eurostar at Brussels Midi, or you clear arrivals at Brussels Airport and look for the train into the city. Either way, the first thing you need is data. A map to your hotel, a message to say you have arrived, a check on the next train. Without it, you are relying on station Wi-Fi and guesswork.

Slashtel gives you a Belgium eSIM that arrives as a QR code by email within a minute of purchase. You install it at home, before you travel, and it activates when it first connects in Belgium. Prices start from $1.99. There is no contract, no local address needed, and no shop to visit. It is data only, so no local number, calls or SMS, but WhatsApp calls work over data and hotspot is allowed.

Who goes and why

UK travellers often come to Belgium for Eurostar city breaks and business trips. Brussels is a short hop from London, and Bruges, Ghent and Antwerp are easy to reach by train. If you are travelling for work, you might need to check email on the move or join a call from the train. A data eSIM keeps you connected without hunting for Wi-Fi or paying your home network's EU roaming charges. Many UK networks now charge extra for roaming in the EU, so a local data plan can be simpler and cheaper.

Indian travellers come to Belgium for business travel and as students. You might be attending meetings in Brussels, visiting the EU institutions, or starting a course in Ghent or Antwerp. Having data from the moment you arrive helps with maps, messaging family back home, and checking university or work emails. Your Indian SIM stays in the phone for bank OTPs and calls, while the eSIM handles your data.

How much data for this trip

If you are a light user on a short break, 1GB is often enough. For longer stays or if you plan to stream video, choose a larger plan to avoid topping up mid-trip.

Two practical notes for Belgium

Arriving by Eurostar means you land in the city centre, so data from the platform is useful. You can check your route to the hotel, order a taxi, or message your host while you are still on the platform. Having data ready means you are not dependent on station Wi-Fi or asking for directions.

Many UK networks now charge extra for roaming in the EU. If you are used to using your UK plan abroad at no extra cost, check the current terms before you travel. A Belgium eSIM gives you a fixed data allowance without surprise charges, and you can top up online on the same eSIM if you run low.

Install before you fly

Install your Belgium eSIM before you fly, while you are on home Wi-Fi. The QR code arrives by email within a minute. You can add the eSIM to your phone and leave it switched off until you land. Your home SIM stays in the phone for calls and OTPs, so you do not lose access to your bank or other verification texts. For step by step instructions, see our installation guide.
