- Orange Belgium — 4G/5G, primary carrier in Bruges and surrounding regions
Belgium eSIM vs UK roaming: real cost in £
Answer: Save up to 85% vs UK roaming. Most travellers spend £4–£15 on a TripSIM Belgium plan instead of £40–£250 on UK roaming for the same trip. The reason is simple — UK carriers charge £5–£8 per MB once you leave EU roaming zones, and Belgium is outside most UK "roam-like-at-home" bundles. A 5 GB TripSIM Belgium plan replaces what would otherwise be £5–£8 per MB × thousands of MB.
- Quick check-in trip (3 days, ~3 GB): TripSIM ~£4–£8 vs UK roaming ~£60+
- Standard holiday (7 days, ~10 GB): TripSIM ~£8–£15 vs UK roaming ~£150+
- Long trip / digital nomad (14+ days, unlimited): TripSIM single fixed price vs uncapped roaming charges
- Heavy maps + video calls user: still capped at the TripSIM plan price — no bill shock

Belgium eSIM frequently asked questions
Will my UK phone work with a Belgium eSIM?
Yes — if your phone is eSIM-compatible (any iPhone XS or newer, Google Pixel 4+, Samsung Galaxy S20+ and most 2020-onward Android flagships) and network-unlocked. Phones bought outright from Apple, Google or the Samsung UK store are unlocked by default. Contract handsets from EE, Vodafone, Three or O2 are unlocked automatically as well.

Activation details land in your inbox within a few minutes of paying. We recommend installing the eSIM at home on UK WiFi before you fly, then activating it when you land in Brussels.

Yes. Modern phones run two SIM profiles at once. Keep your UK SIM as the default voice/SMS line for bank verifications and use the TripSIM eSIM as your data line. WhatsApp, iMessage and your normal apps keep working on your UK number.
