Coverage and network
Coverage in a very online country
Estonia mobile networks
Estonia runs most of its state online and the infrastructure matches: 173 Mbps, 16th globally, ahead of Germany, France and the UK. For a country of 1.3 million people that is unusual, and it shows in how consistent coverage is outside the capital. (Speedtest by Ookla, June 2026)

Tallinn, specifically
- Old Town and Kalamaja: Strong throughout. The medieval walls and cellars weaken it in a few places, and stepping into a courtyard fixes it.
- Beyond the city: Better than most countries this size manage - Tartu, Pärnu and the main roads are well covered, and even the bogs and forests of Lahemaa hold a usable signal near the trailheads.
- The ferry to Helsinki: Two hours across the Gulf of Finland, and both ends are EU, so your plan works either side at domestic rates. Signal fades in the middle of the crossing.
- Saaremaa and the islands: Covered in the towns and along the main roads. Thinner on the smaller islands and the coastal tracks.
Estonia, and the EU
The plan covers all of Estonia, and EU roaming carries it to Latvia, Lithuania or Finland without a second purchase.

Frequently asked questions
Where to buy a SIM card in Tallinn?
Telia, Elisa and Tele2 stores, plus Circle K, Coop, Rimi, R-Kiosk and post offices. It is genuinely easy here.
Do I need ID to buy a prepaid SIM in Estonia?
No, not by law. Estonia proposed mandatory prepaid identification in 2020 and dropped it from the final bill after privacy objections, so there is no registration requirement.
You may see claims online that registration has been "mandatory since January 2024". We could find no legislative source for that and it appears to be recycled SEO copy - treat it as wrong. A shop may still ask for a passport as its own policy, so carry one, but nothing obliges you to register.
Does it work on the ferry to Helsinki and in Latvia?
Yes, in both cases. Estonia, Finland and Latvia are EU members and EU roaming rules put them all on one plan at domestic rates. The gap is physical rather than contractual: mid-Gulf on the Helsinki ferry you can lose signal for a stretch before the Finnish networks pick you up.
eSIM not working in Tallinn?
Mid-crossing on the Helsinki ferry there may be no coverage. In an Old Town cellar, step outside. If neither applies, confirm the phone is using Ohayu for data with roaming permitted, then flip Airplane mode once. Chat and support@ohayu.com are open 24/7.
