What are mobile SIMs in Estonia?

A mobile SIM plan gives you a number and a monthly allowance of data, calls and texts on one of Estonia's mobile networks. Plans split into postpaid (kuupakett), billed monthly under contract, and prepaid (kõnekaart), topped up in advance with no commitment. Estonia is one of the most connected countries in Europe, with dense 4G and rapidly expanding 5G coverage, and SIMs are tightly linked to the national digital identity system.

Because Mobiil-ID uses a special SIM to sign documents and log in to state e-services, the choice of operator and SIM type has practical significance beyond calls and data.

How the Estonian market works

Three network operators run their own infrastructure and compete directly, supplemented by smaller resellers using their networks. Coverage is nationwide and data allowances are generous by European standards, with many plans offering large or effectively unlimited data. EU roaming is included at domestic rates under the EU roam-like-at-home rules.

Buying is simple: eSIM and physical SIM activation can be done online with Smart-ID verification, and porting your number between operators is free and quick. Prepaid SIMs are sold in shops and kiosks nationwide.

Benefits

Fast, wide coverage — Strong 4G everywhere and growing 5G in cities and along major roads.

Generous data — Large and unlimited-data plans are common and competitively priced.

EU roaming included — Use your allowance across the EU at no extra cost.

Digital identity link — Mobiil-ID SIMs enable legally binding signatures and secure state-service login.

How to choose

Start with your real data use and whether you want a contract or prepaid flexibility. Heavy users benefit from unlimited plans; light users save with small prepaid packs. Check 5G availability in your area if speed matters, and confirm whether the plan supports eSIM if your phone is eSIM-only.

If you need Mobiil-ID for signing documents, verify the operator offers it. Compare device-bundle deals carefully, since a subsidised phone locks you into a longer term.

Leading providers in Estonia

Telia Eesti — The largest operator, with the widest coverage and full 5G rollout.

Elisa Eesti — A strong network competitor known for fast data and flexible packages.

Tele2 Eesti — A value-focused operator offering competitive unlimited plans; smaller resellers also use these networks.

What it costs

Monthly plans typically range from around a few euros for small prepaid packs up to about 25 euros for large or unlimited postpaid bundles. Prepaid starter SIMs can be effectively free with a first top-up, while device instalments add to the monthly bill. Roaming within the EU is included, but calls and data outside the EU are charged separately.

Protections and regulation

The market is regulated by the Consumer Protection and Technical Regulatory Authority (TTJA), which oversees spectrum, number portability and consumer terms. EU rules guarantee roam-like-at-home pricing and cap intra-EU call charges. Contract terms, early-termination fees and billing disputes are covered by Estonian consumer law, and porting your number cannot be blocked by an operator.

Common questions

Prepaid or postpaid? Prepaid suits light or short-term users; postpaid gives bigger allowances and device deals for regular users.

Can I keep my number when switching? Yes — number porting between operators is free and takes about one working day.

Do I need a special SIM for Mobiil-ID? Yes, Mobiil-ID requires a compatible SIM from your operator to sign and authenticate.
