Top 10 eSIM providers for Antwerp in 2026
Airalo takes the top spot for Antwerp in 2026. It routes through Proximus for reliable signal even in the Premetro tunnels under Groenplaats. The tie-breaker over second-place Holafly is price. Airalo's 3 GB Belgium plan currently runs around €6.50, while Holafly's cheapest option starts at €19 for unlimited data that most short-stay visitors won't fully use.
Coverage quality in Antwerp varies more than you might expect. The Premetro tunnels under the Groenplaats and Opera stops tend to drop weaker signals, and the narrow streets between Grote Markt and Handschoenmarkt can create dead spots on lower-tier networks. We weighted local network quality at 40% of each score. Proximus-routed providers scored highest on that axis. Per-GB pricing took 35%. Activation ease accounted for the remaining 25%, whether that means QR scan, app download, or physical kiosk. Providers with documented hidden-fee complaints on Trustpilot or Reddit lost up to 15 points.
The most common mistake visitors make at Antwerp-Centraal is buying a physical SIM from the Relay newsstand on the main concourse. An eSIM would have been active before the Thalys even crossed the Belgian border. Another frequent error is grabbing a Europe-wide plan with only 1 GB. You'll pull up De Lijn tram schedules, load Google Maps in Zurenborg to find the Art Nouveau walking route, and video-call from Het Eilandje's waterfront. At that rate, 1 GB disappears in about two days. A 3 GB minimum is more realistic for a 4-day trip.
Airalo is not the right pick for everyone. If you're staying longer than 10 days and plan to work remotely from cafes in Het Zuid or the co-working spaces near Borgerhout, Holafly's unlimited plan makes more financial sense. Airalo's per-GB pricing starts to add up past the 5 GB mark. If you fly into Brussels Airport (BRU) rather than the smaller Deurne airport (ANR), Saily is worth a look for its slightly cheaper Belgium-specific plan on Orange Belgium's network. And if you need voice calls to book restaurant reservations in the Kloosterstraat neighborhood, Airalo's data-only plans won't help. Yesim or Ubigi both offer voice-capable eSIMs for Belgium.
The full list
-
Airalo
Runs on Proximus, Belgium's strongest network, with solid signal inside the Premetro tunnels at Groenplaats and Opera. The 3 GB Belgium plan sits around €6.50, and activation is a 2-minute QR scan you can do on the Thalys before it pulls into Antwerp-Centraal.
-
Holafly
Unlimited data makes sense if you're spending 5+ days exploring from Het Zuid's galleries to the MAS museum in Het Eilandje. Orange Belgium backbone. No per-GB anxiety, though the starting price of €19 is steep for a weekend trip.
-
Saily
NordVPN's eSIM arm routes through Orange Belgium with a Belgium-specific plan that tends to run €1-2 cheaper than Airalo at the 5 GB tier. Coverage holds well around Linkeroever if you cross the Sint-Annatunnel on foot.
-
Nomad eSIM
Competitive per-GB pricing on the Proximus network. Coverage holds well along the De Lijn tram 7 route from Astridplein to the Groenplaats area. App-based activation takes about 3 minutes.
-
Ubigi
One of the few eSIM providers with voice calls in Belgium, which matters if you need to phone restaurants in the Kloosterstraat quarter or book a table near Zurenborg. Runs on Proximus. Slightly pricier per GB than Airalo.
-
Maya Mobile
Budget pick with 1 GB plans starting under €4 for Belgium. Coverage on Proximus is reliable above ground in the Meir shopping district and around Grote Markt, though signal can thin in the deeper Premetro sections.
-
Yesim
Includes voice calling and SMS, a rarity among eSIM providers for Belgium. Coverage on Orange Belgium is steady across the central districts from Groenplaats to the Centraal Station area. Pricing sits mid-range at roughly €8 for 3 GB.
-
aloSIM
Straightforward QR activation, no app required. Routes through Proximus. Per-GB cost is fair but not the cheapest. Works well for visitors arriving at Deurne airport (ANR) who want data active before the 15-minute bus ride into the city center.
-
Roamless
Pay-per-MB model suits travellers who need data in short bursts, like checking De Lijn tram times at the Diamant Premetro stop or translating a menu in Borgerhout. No unused data waste, but heavy users will pay more per GB than a fixed plan.
-
SimOptions
Aggregator that resells plans from multiple carriers including Proximus and Orange Belgium. Useful for comparing Belgium-specific bundles in one place, though activation can take longer than direct providers. Coverage around Het Eilandje and the port area is network-dependent.
