Prepaid Estonia eSIM | Telia, Elisa & Tele2 Coverage
📑 Table of Contents
An Estonia eSIM sounds simple in e-Estonia, but since January 2024 every local prepaid needs in-person ID registration — this guide explains what that means for visitors. Estonia is a 45-by-150 km country that pitches itself as “e-Estonia,” so the question here is not whether the networks are good — on Ookla’s H2 2025 awards, Elisa won both Best and Fastest 5G with a median 5G download of 336.49 Mbps — but whether a foreign visitor can actually get onto one. Since 1 January 2024, every new prepaid SIM (and eSIM) sold in Estonia must be registered against a passport or EU ID card in person, which quietly removes the “walk up and buy a local eSIM” option that exists in most countries. This guide answers three things: which of the three networks your eSIM should ride, how the prepaid-ID wall changes your buying path, and what EU roaming really means when you hop the Tallinn–Helsinki ferry. Our test lines plus the questions travelers actually send us shape what’s below — Estonia quirks included, even the ones carriers would rather skip.
Quick answer: The honest summary: Telia for reach, Tele2 for price, Elisa for speed — and very little separating them in the big cities. If eSIMs are new to you, the activation how-to comes first — the plan tables below can wait.
Some phones cannot take an eSIM at all, and plenty of people have never seen a profile install. Both gaps are covered elsewhere — the eSIM compatibility list and the activation explainer — so this page can stay on the networks.
The 30-second version: City trip to Tallinn or Tartu? Elisa is the fastest 5G network in the country (336 Mbps median). Heading to Lahemaa, Saaremaa or the southeastern forests? Telia holds signal where the others fade and reaches 99% of the population on 4G. Tele2 is the budget third network — fine in cities, thinner in the countryside. You cannot buy a local carrier eSIM remotely as a tourist: since the 2024 ID rule you must visit a Telia or Elisa store with your passport to get a QR code. Skip the paperwork with Roami’s free trial Estonia eSIM, which rides all three networks and needs no in-person registration.
Which Estonia carrier should your eSIM connect to?
Telia vs Elisa: which is better in Estonia?
| Telia | Elisa | Tele2 | |
|---|---|---|---|
| Role | Widest rural/island coverage | Fastest 5G, urban leader | Budget value network |
| Ookla H2 2025 median 5G download | 242 Mbps | 336.49 Mbps (fastest) | 112 Mbps |
| Ookla H2 2025 Speed Score | 57.98 | 64.03 | 43.95 |
| Ookla H2 2025 Connectivity Score | 77.48 | 80.94 | 69.91 |
| 4G population reach | 99%+ | Strong, 97% on 5G | Good in cities |
| Tourist can buy eSIM direct? | In-store only, with passport | In-store / some online, with ID | In-store, with ID |
The single most useful fact on this page: none of the three Estonian networks sells a clean, remote, tourist eSIM. The 2024 registration law means a local eSIM is tied to a passport verified in person, so the practical “which carrier” decision for a visitor is really “which carrier does my travel eSIM ride, and does it switch to the right one per region?”
Networks to know in Estonia
For a visitor, two realities flatten the choice. First, Estonia is small — you can drive Tallinn to Tartu in two hours — so all three cover the populated core. Second, EU “Roam Like at Home” means if you arrive from another EU country, your existing home SIM already works in Estonia at domestic rates (see the roaming section). Carrier choice — and with it, your Estonia eSIM choice — matters most for two groups: visitors from outside the EU/EEA, and anyone leaving the cities or crossing to an island.
Best Estonia eSIM per trip scenario
| Your plans | Go-to carrier | What makes it the pick |
|---|---|---|
| Tallinn city break, Old Town, business | Elisa | Fastest 5G in the capital; median 336 Mbps |
| Tartu, university and startup scene | Elisa | Strong urban 5G throughout the city |
| Lahemaa, Saaremaa, Hiiumaa, forests | Telia | Broadest rural and island coverage; 99% 4G population reach |
| Budget short stay in a city | Tele2 | Cheapest prepaid; adequate in urban areas |
| Crossing to Finland by ferry | Any (EU roaming) | Estonia and Finland are both in the RLAH zone |
| Pärnu & west-coast beach week | Telia | Holds signal along the coastal strip and small peninsulas |
| Narva & the eastern border | Telia | Strongest near the Russian frontier; avoids accidental foreign latch |
| Skiing or hiking in the south (Otepää, Võru) | Telia | 4G reaches the inland valleys the others skip |
What do Telia, Elisa and Tele2 actually charge?
Each of the three runs its own national infrastructure, and each sells prepaid under a distinct brand. Below, who they are, what they charge, and how a visitor actually gets onto them. Prices are the operators’ public prepaid rates; confirm at the point of sale, because tourist packs at the airport carry a markup.
Telia vs Elisa: coverage compared
Telia (the former EMT, still reachable at the internet.emt.ee APN) is Estonia’s largest operator, and a Telia-based Estonia eSIM is the one to trust off the beaten track. Its prepaid brand is Super, managed in the Telia Super app. This is the pick for Saaremaa, Hiiumaa, Lahemaa, the Setomaa southeast and anywhere the other two fade.
Telia Super prepaid (30-day internet passes, EUR / approx USD):
| Data (Estonia) | EU/EEA cap | Price | Approx USD | Validity |
|---|---|---|---|---|
| 1 GB | 1 GB | €3 | ~$3.25 | 30 days |
| 4 GB | 4 GB | €5 | ~$5.45 | 30 days |
| 12 GB | 10 GB | €10 | ~$10.90 | 30 days |
| 40 GB | 30 GB | €18 | ~$19.60 | 30 days |
| 200 GB | 23 GB | €24 | ~$26.15 | 30 days |
How a visitor buys it:
- Go to a Telia Esindus (flagship) store — the nearest full store to the airport is at Ülemiste, a short tram ride from Tallinn Airport.
- Present your passport or EU ID card; staff scan it and register the eSIM against your name (2024 law).
- Pay the starter balance and choose a Super internet pass above (or a combo with calls/SMS).
- The eSIM QR code is issued on the spot; scan it in Settings → Add eSIM.
- Top up later in the Super app or at R-Kiosk, Circle K and Omniva outlets.
Quirk: a €2–5 starter/setup fee is common, and the cheapest passes are data-only — calls and SMS cost extra unless you buy a combo. The 200 GB pass looks generous but its EU roaming cap is only 23 GB, so do not rely on it for a Finland–Estonia loop.
Telia vs Elisa: which carrier is faster?
An Elisa Estonia eSIM is the urban performance pick and the one most travellers in Tallinn actually notice. Its prepaid brand is Zen (zen.ee), managed in the Elisa Zen app, and it uniquely sells short daily unlimited passes that suit a weekend visit better than a 30-day bundle.
Elisa Zen prepaid (30-day plans unless noted, EUR / approx USD):
| Data | Price | Approx USD | Validity |
|---|---|---|---|
| 2 GB | €4.99 | ~$5.45 | 30 days |
| 8 GB | €7.99 | ~$8.70 | 30 days |
| Unlimited | €22.99 | ~$25.00 | 30 days |
| Daily unlimited | €1.99–2.99 | ~$2.20–3.25 | 1 day |
How a visitor buys it:
- Elisa is sold at Elisa Esindus stores, at R-Kiosk (including inside Tallinn Airport), and at supermarkets such as Rimi, Prisma and Maxima.
- Show your passport or EU ID card; the clerk registers the eSIM against it.
- Pay and load a Zen plan; the QR code arrives by email or is scanned in store.
- For a sub-five-day stay, the daily pass is usually cheaper than a 30-day bundle.
Quirk: Elisa’s core prepaid plans do not include EU roaming by default — the daily pass and the 30-day Zen plans are Estonia-only unless you add a roaming option. If you plan to ferry to Helsinki, treat Elisa as an Estonia-only product.
Tele2 eSIM: the budget option in Estonia
A Tele2 Estonia eSIM is the price challenger and fine in any city, but the network’s 4G thins out in the countryside and on the islands. Its prepaid brand is simply Tele2 Smart, managed in the Tele2 Iseteenindus app.
Tele2 Smart prepaid (30-day plans, EUR / approx USD):
| Data | Price | Approx USD | Validity |
|---|---|---|---|
| 5 GB | €5.99 | ~$6.50 | 30 days |
| 15 GB | €9.99 | ~$10.90 | 30 days |
| Unlimited | €18.99 | ~$20.70 | 30 days |
How a visitor buys it:
- Tele2 Esindus stores and R-Kiosk (Tallinn Airport included) sell starter packs.
- Present your passport or EU ID card for in-person registration.
- Choose a Smart plan; scan the eSIM QR code.
- Top up in the Iseteenindus app.
Quirk: Tele2’s prepaid caps EU roaming hard and its coverage is the weakest of the three outside towns, so it is the right call only if you stay in Tallinn, Tartu or Pärnu and want the lowest price.
Why can’t I buy an Estonian eSIM before I fly?
Estonia changed the game on 1 January 2024: every new prepaid SIM card — physical or eSIM — must be registered to a valid government-issued photo ID. Accepted documents are a passport or an EU/EEA national ID card. There are no exemptions for tourists, and the process is done in person at an official operator store (Telia Esindus, Elisa Esindus, or Tele2 Esindus), where staff scan the document and issue the eSIM QR code. A setup fee of roughly €2–5 may apply.
What this means in practice:
- You cannot pre-order a Telia/Elisa/Tele2 eSIM from abroad and arrive with it ready. The ID check happens at the store.
- Airport and kiosk SIMs are limited. Tallinn Airport has Elisa at R-Kiosk but no Telia counter inside the terminal; the nearest full Telia store is at Ülemiste, a short tram ride away. Weekend and evening arrivals often find shops closed.
- A global travel eSIM bypasses the wall. Providers such as Roami, Airalo and Holafly sell data-only Estonia eSIMs that install by QR code before you fly — no passport scan, no store visit. The trade-off is they are data-only (no +372 number) and cost more per gigabyte than a local prepaid.
Estonia’s regulator, the Consumer Protection and Technical Regulatory Authority (TTJA), maintains the national coverage map, and the ID rule is enforced uniformly across all three operators.
Will my eSIM still work outside Estonia?
Estonia is inside the EU/EEA, so “Roam Like at Home” (EU Regulation 2022/612, guaranteed through 2032) applies. But the details catch visitors:
- EU visitors: your home SIM works in Estonia at domestic rates, no surcharge. This is why many EU travellers never buy a local SIM at all.
- Local prepaid plans are not automatically roaming-inclusive. Elisa and Tele2 core prepaid plans do not include EU roaming by default; Telia’s Super prepaid (€24/200 GB) includes an EU fair-use allowance of just 23 GB — an 88.5% reduction from the domestic bucket. If you buy a local prepaid and then cross into Finland or Latvia, you may hit a wall.
- The wholesale cap ceiling: the EU caps what visited networks can charge for roaming data — €1.30/GB in 2025, dropping to €1.10/GB in 2026 and €1.00/GB in 2027 per the European Commission’s RLAH rules. That is the most a carrier can bill; many tourist plans simply cap or block roaming instead.
- Tallinn–Helsinki ferry: the 2-hour crossing is a real use case. Onboard you usually have ship Wi-Fi or Finnish coastal signal; in open-water gaps there is nothing. Once you dock in Helsinki you are back in the RLAH zone, so an Estonia eSIM that includes EU/EEA coverage keeps working without a second plan.
Abroad on an Estonia eSIM
Estonia shares a land border with Russia along the Narva River (Narva and Ivangorod face each other across the water) and around the southeastern Setomaa area. Within a few kilometres of that frontier your phone can latch onto a Russian operator — Megafon, MTS, Beeline or Tele2 Russia — which is outside the EU/EEA and outside Roam Like at Home entirely. A local prepaid or even a travel eSIM can silently start billing Russian roaming rates, or simply drop, in those pockets. If your itinerary reaches Narva, Valga (the Latvia side is fine, but the border zone is busy) or the far southeast, switch Network Selection to manual and force Telia/Elisa/Tele2 so the phone cannot camp on a Russian tower. This is the one place in Estonia where carrier choice and manual selection genuinely protect your wallet.
How fast is mobile data in Estonia overall?
These are the national-level figures behind the per-carrier numbers above.
- Ookla Speedtest Global Index (August 2026): Estonia ranks 24th globally for mobile, median download 140.42 Mbps at 18 ms latency — well above the 109.05 Mbps global median.
- Cable.co.uk per-GB pricing: roughly USD 1.15 per GB, 107th of 237 markets, against a USD 2.59 global average. Local data is cheap once you are on a resident plan; airport tourist packs (~€25 for 5 GB) are the expensive exception.
- DataReportal Digital 2025: 1.26 million internet users (93.2% of the population) and 1.91 million mobile connections (141% of the population) — a mature, near-saturated market.
For context on the networks specifically, Ookla’s Estonia Speedtest Awards page is the source for every per-carrier figure above.
Estonia eSIM coverage: Telia vs Elisa
Estonia’s 24th-place world rank is a national average. Here is how it actually breaks down for a traveller.
| Area | What to expect | Best carrier | Watch out |
|---|---|---|---|
| Tallinn & Harju | 5G on all three networks; holds along the Tallinn–Tartu and Tallinn–Pärnu highways | Elisa | Old Town congestion during cruise season; older buildings have patchy indoor signal |
| Tartu & south | Strong urban 5G; rarely drops to 4G downtown | Elisa | Võru and Otepää inland valleys prefer Telia |
| Pärnu & west coast | Solid along the coastal strip; patchier on small peninsulas | Telia | Very crowded in July |
| Lahemaa National Park | Fine in villages and along main roads | Telia | Forest and bog boardwalk trails have no signal |
| Saaremaa & Hiiumaa | Telia reaches the islands; budget carriers do not | Telia | Don’t rely on a cheap prepaid off the mainland |
| Narva & eastern border | Telia strongest near the Russian frontier | Telia | Russian towers lure phones into non-EU roaming |
| Setomaa & southeast | Telia 4G reaches the villages | Telia | Gaps between settlements; no signal deep in forest |
| Elron trains | Free onboard Wi-Fi supplements the network | Telia | Wi-Fi, not mobile, on rural stretches |

The APN each Estonian network uses
You only need these if you bought a SIM or eSIM directly from an Estonian carrier and it did not auto-configure. Travel eSIMs supply their own APN — leave them alone.
| Carrier | APN | Username | Password |
|---|---|---|---|
| Telia (EMT) | internet.emt.ee |
blank | blank |
| Elisa | internet |
blank | blank |
| Tele2 | internet.tele2.ee |
blank | blank |
- iPhone: Settings → Cellular → tap the eSIM line → Cellular Data Network → enter the APN.
- Android: Settings → Network & Internet → Mobile Network → Access Point Names → add a new APN.
Save and reboot. If data still fails, confirm the eSIM — not your home SIM — is the selected data line before changing anything else.
Estonia eSIM registration: passport, TTJA scan and payment before the counter
Because the 2024 rule puts a Telia, Elisa or Tele2 clerk between you and any local profile, the packing list starts with the documents that survive a TTJA scan — and with a realistic plan for the hours when no counter is open.
- EID — dial
*#06#to surface it. A travel eSIM wants the number before it ships; a local profile is only issued to you once the TTJA scan is done, so you cannot collect one in advance. - Passport or EU ID card, the original — the 2024 law reads the actual document in person. A photocopy, a phone photo and a driving licence are all turned away at the Esindus.
- A card that clears outside its home region — Estonian operator terminals sometimes decline non-EU billing. Apple Pay, Google Pay or euro cash at the counter saves you the errand.
- Install any travel eSIM before you fly — there is no arrive-and-buy path that skips the passport step, and Tallinn’s counters keep closed hours at the weekend.
- Leave your home line switched on — Bolt, parking meters and guesthouse bookings text codes to your normal number, which a data-only eSIM cannot receive.
- Switch Data Roaming on for the eSIM — odd advice inside the EU, but without it the profile sits at “No Service”; see the setup list below.
- A weekday arrival if a +372 number matters — Telia’s nearest full Esindus is at Ülemiste rather than the terminal, and Elisa’s R-Kiosk counter inside the airport is the one landside option that reliably opens at weekends.
- The exact spelling your passport prints — the TTJA record is tied to that name, and a mismatch surfaces later as a failed identity check at the operator rather than at the till.
- A note of which document the line went on — losing the handset means a replacement SIM re-registered against the same passport, so keep the ID page details somewhere you can read them offline.
What should I check before I land in Estonia?
| Check | The Estonian detail behind it |
|---|---|
| Original passport or EU ID card packed | Only an original document clears the TTJA scan; a driving licence or a photo on your phone is refused at the counter |
| Data Roaming switched ON for the eSIM line | Estonia sits inside the RLAH zone, so it feels wrong — but a profile with roaming off shows “No Service” the moment it lands |
| Shop hours checked if you want a local profile | Telia’s nearest full counter is at Ülemiste rather than the terminal, Elisa sells via R-Kiosk inside the airport, and weekend arrivals often find both shut |
| A card that clears outside your home region | Some Estonian terminals decline non-EU billing cards, so carry Apple Pay, Google Pay or euro cash as the fallback |
| Home line kept alive for verification texts | Bolt, parking apps and guesthouse bookings all push SMS codes that a data-only eSIM cannot receive |
| Offline maps saved for the islands and the southeast | Saaremaa, Hiiumaa and the Setomaa forest roads carry genuine dead spots; download routes before leaving Wi-Fi |
The roaming toggle is the step people skip: leave it off and the profile sits at “No Service” even though Estonia levies no roaming surcharge at all.
Estonia eSIM problems and fixes
A QR code that will not scan, a profile stalled mid-install, a phone with no line at all — none of that is an Estonian fault. Those belong to the generic eSIM error troubleshooting guide, and the ground-up walkthrough sits in how to activate an eSIM. What follows are the four failures this country produces on its own.
What forms come with an Estonia SIM?
If your Telia, Elisa or Tele2 profile came from a counter, it only goes live once the clerk finishes the TTJA registration scan against your passport. A registration that was started but never transmitted leaves the eSIM parked at “No Service”, while the QR code itself looks perfectly healthy — which is why this fault is so easily misread as a handset problem.
The fix is administrative rather than a setting. Return to the same Esindus with the same document and ask staff to confirm the registration was sent; some branches complete it later the same working day.
Who has the widest reach in Estonia?
Close to the Russian border a handset will happily camp on Megafon, MTS or Beeline, because those masts sit nearer and often transmit louder than Telia’s. Data then either flatlines or, worse, starts billing non-EU roaming with no warning on screen.
Pin the network by hand: Settings → Cellular → Network Selection, switch off automatic and choose Telia, Elisa or Tele2. Telia holds best along the Narva river and through the southeastern villages, and manual selection stops the phone drifting across the water on its own.
Does 10 GB last for Estonia?
Estonian prepaid plans are frugal with Roam Like at Home. Elisa and Tele2 core bundles exclude EU roaming outright, and even Telia’s 200 GB pass concedes only 23 GB beyond the border. Sail to Finland on a local prepaid and you meet that ceiling, not a coverage gap.
Read the plan’s EU allowance before you board the ferry, or run the crossing on a travel eSIM whose EU/EEA bucket is stated plainly at checkout.
Is your device approved for Estonia eSIMs?
An install that loops near the end is frequently a VPN problem, and Estonia sees more than its share because so many visitors arrive tunnelled through a work profile. Kill the VPN, close its app, and restart the install on hotel Wi-Fi before you touch any other setting.
When you call Telia, Elisa or Tele2 about an eSIM
Estonian desks work from the registration record rather than an online order, so lead with the ID trail:
| What they will ask | Where it lives |
|---|---|
| The document the line was registered against | The passport or EU ID scanned at the Esindus |
| Which Estonian network you are camped on | The eSIM line name under Settings → Cellular |
| Whether the EU allowance has been exceeded | The plan’s roaming bucket, not the domestic one |
| How close you were to the Russian border | Name the town — Narva and Setomaa change the diagnosis |
| A screen grab of the fault | Capture it before the screen clears |
Telia’s private-customer line is 123 inside Estonia (+372 639 7130 from abroad); Elisa answers on 6 600 600, or the short code *166 from an Elisa handset; Tele2 is on 686 68 66. If a provider will not resolve a complaint, the TTJA takes it on 667 2000. A travel eSIM leaves no record with any of them, so keep your confirmation email, your EID (*#06#) and a screenshot for your own provider instead.
Estonia eSIM questions worth asking
Can you buy an Estonia eSIM from Telia Estonia?
Not remotely. Since 1 January 2024 all prepaid SIMs and eSIMs must be registered in person against a passport or EU ID card, so Telia, Elisa and Tele2 issue the profile at a store after ID verification. A travel eSIM (Roami, Airalo, Holafly) installs by QR code before you fly and needs no in-person registration — that is the visitor path.
Which Estonia carrier posts the top speeds?
Elisa, on Ookla’s H2 2025 awards (cross-checked by Telecompaper): median 5G download of 336.49 Mbps, a Speed Score of 64.03 and the best Connectivity Score (80.94). Telia follows on speed (242 Mbps median 5G) and leads on rural reach; Tele2 is the value network at 112 Mbps median 5G.
Rural coverage in Estonia: Telia vs Elisa
Telia, with 4G reaching 99%+ of the population and the strongest signal on Saaremaa, Hiiumaa and in Lahemaa and the southeastern forests. If your itinerary leaves the cities, Telia is the safest pick.
Do Estonian prepaid plans include EU roaming?
Often not. Elisa and Tele2 core prepaid plans block or limit EU roaming; Telia’s Super prepaid cuts the EU allowance to 23 GB of a 200 GB bucket. EU visitors should just use their home SIM under Roam Like at Home; everyone else should pick a travel eSIM that explicitly includes EU/EEA coverage.
How closely does Estonia check registrations?
A local prepaid eSIM, yes — in person, with a passport, since the 2024 law. A data-only travel eSIM with no Estonian number is not subject to that registration, which is exactly why it is the easier visitor option.
APN values for Telia Estonia and Elisa Estonia eSIMs
Telia uses internet.emt.ee, Elisa uses internet, Tele2 uses internet.tele2.ee — all with blank username and password. Most phones auto-configure; only set it manually if data fails after a direct-carrier install.
Will my eSIM work on the Tallinn–Helsinki ferry?
In port and along the coast, yes. In open water there are gaps; onboard Wi-Fi or Finnish coastal signal covers most of the crossing. In Helsinki you are back in the EU roaming zone.
Can I keep my home SIM and the Estonia eSIM active at the same time?
Yes, and it is the sensible setup. Keep your home number on the physical SIM for calls and SMS verification — Estonia’s Bolt, parking apps and many bookings send codes to it — and run data, including any laptop tethering, on the eSIM. Just switch Data Roaming off on the home line so you are not billed for background traffic.
Crossing borders with an Estonia eSIM
The border matters here, specifically for billing. Within a few km of the Narva and Setomaa frontier your phone can camp on a Russian network outside the EU. Set Network Selection to manual and pick Telia/Elisa/Tele2, and never answer or dial on a connection that shows a Russian operator.
Is Tallinn Airport Wi-Fi enough to get by?
The free airport Wi-Fi is fine for a quick message, but it is not a substitute for data once you are in the Old Town, on a rural road, or on the ferry. Install your eSIM before you fly rather than relying on airport hotspots.
Which Estonia carrier should you pick: Telia or Elisa?
Ask the carrier it is locked to; many will unlock on request. On iPhone check Settings → General → About → Carrier Lock. A locked phone cannot install any third-party eSIM until it is unlocked.
Which companies run Estonia’s networks?
Direct means one network, in-person passport registration, and a local +372 number. Travel means instant QR delivery, no ID, automatic switching across Telia/Elisa/Tele2, and a fixed upfront price — best for trips under a few weeks.

- Carrier pages: Telia Eesti, Elisa Eesti and Tele2 Eesti for eSIM availability, registration and APN values.
Every speed figure above is a third-party reading rather than our own test, so yours will shift with the handset, the band in play and how loaded that Tallinn or Saaremaa cell happens to be.
Get your Estonia eSIM ready before you fly
Roami’s Estonia profile draws on Telia, Elisa and Tele2 and passes you to whichever is strongest as you move — Elisa’s 336 Mbps through central Tallinn, Telia’s 99% reach out on Saaremaa — with nothing to sign at a counter and no €2–5 setup fee at Ülemiste.
Never used Roami? Start on a free Estonia trial eSIM before you pay anything. When you are ready to buy, code WEB20 takes 20% off a paid Estonia plan, and if the Helsinki ferry is on the itinerary pick the version that carries EU/EEA coverage rather than a 23 GB cap.
