EXIT Festival packs four nights, six to twelve stages, and roughly 200,000 attendees onto the walls of Petrovaradin Fortress. You will lose your group at least twice per night. The fortress is a maze. The cleanest way to find people again is a pinned WhatsApp location and a working data line — and that is exactly the moment when a tourist on home roaming hits their cap and the line dies.
An eSIM bought before your flight handles all of that. You leave home, fly in, install nothing extra at the festival itself, and have continuous coverage from arrival to the moment you fly home. Yettel and A1 both reinforce capacity at Petrovaradin during the festival nights, so signal stays usable even at peak crowd density.
Pick at least a 5 GB plan for a four-night festival run — Google Maps in offline mode helps, but photos, video calls home, ride-share to the city, and constant messaging chew through data faster than most people expect. If you are staying longer in Novi Sad before or after, take 10 GB / 15 days and have headroom.
Charge before you leave the apartment. Bring a 10,000–20,000 mAh power bank — phones with active eSIMs and constant GPS drain fast. Pre-download offline maps of Petrovaradin and your Novi Sad neighbourhood on Wi-Fi. Tag your accommodation as a shortcut in Google Maps so you can navigate home even if your data slows down at 4 AM.
<p>Generally yes — operators deploy mobile cell sites for the festival run. Voice calls can struggle at peak moments, but messaging and ride-hail consistently work.</p>
<p>Each eSIM activates on one phone. You can tether your eSIM to a friend's device over Wi-Fi hotspot, but that drains your battery fast and reduces speed. For a group of 3–4 the simplest setup is one eSIM each.</p>
<p>Yes — and it is the single most useful feature for keeping a festival group together. Set it to 8 or 15 hours so you do not lose the link mid-night.</p>
<p>Top up from your provider's app — both Airalo and Holafly let you buy add-ons in one tap. Make sure you have Wi-Fi access (your hotel) when you do.</p>
