About the operator
Telia is the largest telecom group in the Nordics and Baltics, a partially Swedish state-owned operator with leading mobile networks from Norway to Estonia.
The company was formed in 2002 by the merger of Sweden's Telia and Finland's Sonera, traded as TeliaSonera until 2016, and is headquartered in Solna, near Stockholm; the Swedish state remains its largest shareholder. Today it runs networks in Sweden, Finland, Norway, Denmark, Lithuania and Estonia. Telia Norway, built on the former NetCom, is the country's second-largest mobile operator, while Telia Estonia — heir to the historic EMT and Eesti Telekom — is the Estonian market's biggest telecom.
For travelers, AviaeSIM's prepaid eSIM plans on the Telia network currently cover Norway and Estonia. That means the same coverage locals rely on — from Oslo and the fjord country to Tallinn's old town — delivered as a QR code by email, with no store visit and no Nordic roaming bills.

Network & technology
Telia runs modern 4G and 5G networks across its markets. In Norway, its 4G covers nearly the whole population and 5G has reached most inhabited areas since 3G was retired in 2021; coverage holds up well along fjords and highways, though remote mountain valleys can still drop signal. Telia Estonia pairs near-universal 4G with expanding 5G in Tallinn, Tartu and other cities — fitting for one of Europe's most digital societies.
Reputation & market position
Telia is the incumbent-quality brand across its footprint: in Norway it is the main challenger to Telenor with consistently strong network test results, and in Estonia it is the dominant, trusted incumbent. The group is known for solid engineering and enterprise services; criticism tends to focus on premium pricing and on the 2010s corruption case over its Uzbekistan entry, which the company settled and has long since exited.
Pros
- Top-tier network quality in both Norway and Estonia
- Near-universal 4G population coverage with 5G widely deployed
- Estonia's leading operator and Norway's strong number two
- AviaeSIM prepaid plans use the Telia network without any Norwegian or Estonian ID or contract
Cons
- Premium price positioning in its home markets
- In remote Norwegian mountains and islands, Telenor's rural coverage is sometimes stronger
- Legacy reputational baggage from the 2010s Eurasian corruption settlement

Frequently asked questions
Does Telia offer eSIM?
Yes. Telia supports eSIM in both Norway and Estonia for its own subscribers — you order one through the Telia app, website or a store, with normal customer identification. Travelers who just need mobile data can skip that entirely: AviaeSIM prepaid travel eSIMs run on the Telia network in Norway and Estonia and are delivered as a QR code by email minutes after purchase.
Can I get a Telia prepaid eSIM?
Telia's own prepaid products vary by country and are aimed mainly at residents; moving a prepaid SIM to eSIM may require a store visit. The travel-friendly alternative is an AviaeSIM prepaid eSIM on the Telia network: choose a data package for Norway or Estonia, pay online, install it via QR code, and start using data on arrival — no Telia account or local registration needed.
What are Telia's tariffs for travelers?
Telia's consumer tariffs are designed for residents of each country and change frequently, so check Telia's local sites for current plans. If you are only visiting Norway or Estonia, comparing local tariffs usually is not worth the effort — an AviaeSIM prepaid data plan on the Telia network shows its full price upfront, works immediately after QR installation and avoids roaming charges entirely.
How good is Telia coverage for tourists in Norway and Estonia?
Very good. In Norway, Telia's 4G reaches nearly the entire population and 5G covers most inhabited areas, including the popular fjord routes; only remote mountain terrain gets patchy. In Estonia coverage is close to universal, from Tallinn and Tartu to the islands. AviaeSIM plans connect to these same Telia networks, so a travel eSIM gets the same coverage as a local SIM.
