The best eSIM for Estonia depends on how much data you need, but for a typical trip eSIM Ahora offers plans from $0.88, activated by QR code in about 30 seconds with no roaming from your home carrier. A 3 GB, 30-day plan costs $3.68. You connect, with top-ups available and nationwide coverage. It includes EU roaming if you continue your trip across Europe. Compatible with iPhone XS or newer, Samsung Galaxy S21+ and Google Pixel 3+.
Full-speed data every day; after the daily cap the speed is reduced.
Full speed up to 500 MB/day, then 512 Kbps.
Every eSIM can be installed within 180 days of purchase. Plan validity starts when you first connect.
Your eSIM picks between these networks on its own. If you see bars and nothing loads, you can pick one by hand.
Your Estonia eSIM runs on Tele2 and Telia, and your phone picks whichever has the better signal. Other local networks won't carry your data: if you see signal bars and nothing loads, turn off automatic network selection (iPhone: Settings → Cellular → your eSIM → Network Selection; Android: Settings → Network & internet → SIMs → your eSIM) and pick Tele2 or Telia by hand.
Telia, Elisa and Tele2 cover Estonia with 5G across Tallinn, Tartu, Pärnu and Narva — among the fastest mobile networks per capita in Europe. Excellent 4G even on Saaremaa and Hiiumaa islands and rural Lääne-Viru. Dense forests in Lahemaa national park can have spotty signal. Estonia is the birthplace of e-Residency and nearly all government services run online — you'll need data for e-services, Smart-ID and mobile banking outside public Wi-Fi. EU roam-like-at-home applies. Type C/F plugs, 230V/50Hz.
Fly into Tallinn (TLL); the airport is 4 km from the Old Town, tram #4 costs 2€. Euro is the currency. Tallinn Card covers transit and museums. Tartu (the university city) is 2h by bus on Lux Express. Ferries to Helsinki take 2h — easy day-trip. Bolt was founded here and is the dominant app (rides, scooters, food delivery). Saunas are national culture — public sauna in Tallinn from 12€. Craft beer and modern Nordic restaurants concentrate in Telliskivi. Long winters: November-March with short daylight.
