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 $1.79. 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.
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.
| Data | Duration | What it covers |
|---|---|---|
| 1GB | 3-5 days | Maps, WhatsApp text, light email. No video. |
| 3GB | 1 week | Maps, WhatsApp calls, occasional social media. |
| 5GB | 2 weeks | Maps, WhatsApp video, some music streaming. |
| 10GB | 1 month | Daily use including video and video calls. |
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.
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 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. If you are keeping your Indian SIM active, read our guide on keeping your Indian SIM active.
Ready to travel? Browse Belgium data plans and choose the size that fits your trip. Prices start from $1.79. The eSIM is data only, with no local number, calls or SMS. WhatsApp calls work over data, and hotspot is allowed. Top-ups are done online on the same eSIM, so you can add more data if you need it without buying a new plan. Days start counting only when it first connects at the destination, so you can install it early without wasting days.

Your phone must be unlocked and eSIM compatible. Most recent iPhones and many Android handsets support eSIM, but it is worth checking your settings before you buy. If your phone is locked to a network, ask that network to unlock it first.
Yes. Your Belgium eSIM is data only, so you can leave your home SIM in the phone for calls and SMS. That means bank OTPs and other verification texts still arrive on your usual number. Just make sure data roaming is switched off on your home SIM so you do not run up charges.
For a short city break of three to five days, 1GB is enough for maps, WhatsApp text and light email. For a week, 3GB covers maps, WhatsApp calls and occasional social media. If you are staying for two weeks and plan to use video or stream music, choose 5GB or more.
Install it before you fly, while you are still on home Wi-Fi. The QR code arrives by email within a minute of purchase. You can add the eSIM to your phone and leave it switched off until you land. It only starts counting days when it first connects in Belgium.
Yes, you can expect data coverage in all four cities on a major local network. If you arrive by Eurostar, you land in the city centre, so data from the platform is useful for maps and messages. Coverage is generally good in urban areas, but it can be weaker inside thick-walled buildings or in some rural parts of Belgium.
Yes, hotspot is allowed on your Belgium eSIM. You can share your data with a laptop or tablet when you need to work. Just keep an eye on your data usage, as tethering can use more than you expect.
For most trips a 5GB to 10GB data eSIM valid for 30 days is the right size: Slashtel's 5GB plan for Belgium is $5.69 on Proximus, Orange and Base. Install it before you fly, keep your home SIM on for calls and bank texts, and top up the same eSIM if you run low.
If your phone supports eSIM, an eSIM is simpler than a local SIM card: nothing to collect at the airport, no passport registration, and your home SIM stays in the phone for calls and OTP texts. A physical SIM only makes sense for long stays where you need a local phone number.
From $1.79 for 1GB valid 7 days, as of 9 October 2026. Longer trips: two weeks from $3.79 (3GB), one month from $3.99 (3GB).

No. Slashtel eSIMs are data only, with no local number, calls or SMS. WhatsApp and other internet calls work, and your home SIM can stay on for calls and OTP texts.
