You do not get a new phone number with this eSIM.
Setting up your eSIM? The installation and activation guide walks through it step by step, and the full FAQ covers device compatibility, hotspot, dual SIM and topping up.
One plan covers the whole country, so the same eSIM works in Brussels, Bruges, Ghent and Antwerp - all an easy train ride apart. Install it before you travel, switch off airplane mode on arrival, and you are online for tickets, maps and bookings.
The eSIM connects automatically when you turn off airplane mode at Brussels (BRU), Brussels South Charleroi (CRL) or Antwerp (ANR). Your train into the centre, the SNCB app and maps are ready the moment you land.
Belgium's networks - Proximus, Orange Belgium and BASE - give dense 4G/5G coverage nationwide. Because the country is small and flat, signal is consistent in the cities, the historic centres and on the trains between them, with few of the rural gaps larger countries see.
The same eSIM works as you string the cities together by rail - Brussels to Bruges, Ghent and Antwerp in well under an hour each. Belgium is also a gateway to its neighbours; if your trip continues into France, the Netherlands or Germany, consider a Europe regional plan so one eSIM covers them all.
Most British visitors reach Belgium by train: Eurostar runs city centre to city centre in about two hours. If you go that way, the EU's Entry/Exit System - fingerprints and a photo on your first trip - is done at St Pancras before you leave the UK, not in Brussels. By air, Brussels Airlines and British Airways fly from Heathrow in just over an hour.
Belgium is in the Schengen area, so the usual passport rules apply (issued within ten years, valid three months after you leave), and you must carry your passport at all times while there. Declare 10,000 euros or more in cash. The Foreign Office suggests downloading the official 112 BE emergency app (gov.uk, updated 7 October 2026).
Belgium is in every big UK network's Europe zone: included on O2 up to 25GB and on Vodafone plans with Euro Roam or Global Roam, otherwise £2.75 a day on Vodafone, £2.72 on EE and £2 or £2.75 on Three. Sockets are the European two-pin kind, and Belgium is one hour ahead of the UK.
Yes. You stay online across the rail network connecting the main cities, so the SNCB app, live maps and bookings work throughout your day trips.
Yes. Belgium has dense, consistent 4G/5G coverage, so the medieval centres of Bruges and Ghent and the cities are all well covered.
A Belgium plan covers Belgium. If your trip also takes in France, the Netherlands or Germany, a Europe regional plan lets a single eSIM cover the whole route.
At St Pancras International, before you leave the UK: the Foreign Office says Eurostar passengers have their Entry/Exit System details taken at the border there (gov.uk, updated 7 October 2026).
