Estonia

Basics
The country of Estonia has 3 network providers: 2G is on 900 and 1800 MHz, 3G is on 900 and 2100 MHz with good coverage, 4G/LTE has started on 800, 1800 and 2600 MHz (and 2100 MHz new on Tele2) on all three networks all over the country and is generally available for prepaid.
 * Telia (formerly EMT, owned by the Swedish TeliaSonera Group)
 * Elisa (owned by Finnish Elisa Oyj)
 * Tele2 (owned by Swedish Tele2 Group)

Prepaid SIM cards called ' Kõnekaart' are available at newsstands, kiosks, supermarkets, other outlets and the shops of the providers. No ID or registration is necessary. Like other Baltic states, Estonia offers low prices for data compared to the rest of Europe.

Reloads
While being within the country, you can buy voucher codes at many outlets. But it's a different story from out of the country.

It's problematic to recharge an Estonian mobile number from abroad without having an Estonian bank account (SEB, Swedbank, Nordea or Danske Bank) even if SEPA topups should theoretically work (see below). There are no credit (or debit) card payment options. Furthermore, there are no 3rd party dealers or agencies who recharge online. So if you want to top-up an Estonian mobile number from other countries, take vouchers with you or find an Estonian friend, who will buy it for you staying in the country.

Telia (formerly called EMT) (Super, Simpel)
Telia has been rebranded from EMT in 2016. It's owned by the Swedish Telia Company and market leader in Estonia with a 42% share of the mobile market in 2016. Their 4G/LTE network covers most of the country already and is open for prepaid.

Availability
Their prepaid kit is available at Telia (formerly EMT and Elion) stores and in lot of their outlets. Recharges can be made at theseplaces nationwide. Their two brands for prepaid kõnekaarts are called Super and Simpel. Topup voucher validity is limited. Telia provides explicit instructions in English for topup by SEPA (do note that IBANs for domestic and int'l topup are different).
