For an optimal start to your Estonian adventure, we strongly advise activating your eSIM Routes QR code before you depart for your trip, ideally while you are still in your home country. This proactive approach guarantees that your data service is immediately live the moment you land at Lennart Meri Tallinn Airport (TLL). You can then instantly access maps, transportation apps, and communicate with ease, bypassing the need to hunt for free Wi-Fi upon arrival and keeping your itinerary on schedule.
