Heading to the world's largest tech conference? GleeSim gives Web Summit attendees a Portugal travel eSIM activated in minutes via WhatsApp. No app to download, no SIM counter at Lisbon Airport, and no roaming bill waiting when the closing keynote wraps.
Web Summit spreads across the Altice Arena and the adjacent FIL exhibition centre, plus a city full of Night Summit events after hours. Between the conference app, investor calls, and pitching from the show floor, attendees burn through far more data in Lisbon than on a normal city break.
Altice Arena and FIL together host tens of thousands of attendees across multiple stages. The official Web Summit app and venue maps both need a live connection to get you between meetups on time.
Web Summit's matching and meetup system pushes notifications and confirms locations in real time. Miss a data window and you miss the investor meeting.
The after-hours networking events happen at bars and venues scattered around Lisbon, not just at the arena. Maps and rideshare apps need to keep working well past midnight.
Free EU roaming only applies within the EU itself. Attendees flying in from the US, UK, Brazil or Asia can still face steep per-day roaming charges across four packed conference days.
Demoing a product, sharing a deck, or jumping on a follow-up call from the startup village all need dependable data, right when it matters most.
Web Summit also runs in Rio, Qatar and Vancouver. If Lisbon is one leg of a wider conference circuit, one provider covering 190+ countries beats juggling a new SIM at every stop.
The best eSIM for Web Summit is a Portugal travel eSIM that activates before you land and needs no app, no account, and no SIM swap at the airport. GleeSim is a WhatsApp-managed travel eSIM, with buying, activating and topping up handled entirely inside a WhatsApp chat.
Web Summit runs Centre Stage keynotes alongside a full programme of themed content across the venue, so most attendees plan their days around a rough focus area rather than trying to see everything.
Keynotes from major tech leaders and investors, covering fundraising, AI, and where global venture capital is moving next.
Thousands of exhibiting startups, pitch competitions, and investor meetups spread across the FIL exhibition floor.
Off-site networking events across Lisbon's bars and venues once the day's sessions wrap, running deep into the evening.
No account creation, no separate app to configure in the queue at Lisbon Airport.

An eSIM for Web Summit suits more than just first-time attendees.
Demoing on the show floor, sharing decks with investors, and staying reachable for follow-ups all depend on data that does not run out mid-pitch.
Back-to-back meetups across two venues need a phone that keeps calendars, calls and the meetup app in sync all day.
Companies sending a group to Lisbon can get every team member connected on arrival without setting up individual roaming plans.
Filming interviews, uploading footage, and posting live from the show floor all burn through data far faster than a normal trip.
