Calling in Estonia: you do not need to use the Estonian country code (372), but only a 7 or 8 digit number as they are in Estonia.
International long distance calls: dial 00 + country code + area code and local number.
Calling to Estonia from abroad: dial whatever you need to get an international line in your home country, then 00372 (Estonia’s country code), and then the local number.
There are several mobile communication operators in Estonia. They offer many different price packages – you have to choose which one is best for you. The easiest way is to use a prepaid SIM card (the initial credit may vary in different companies), as then you do not need any contract. All international students get a prepaid SIM card at the orientation course, but you can also buy them at shops and kiosks.
Main mobile operators are Telia, Elisa and TELE2 (all three have offices in Kaubamaja and Lõunakeskus).
If you have decided to make a contract with a local company, be aware that calls are billed on a monthly cycle. For example, your phone bill for January is delivered in mid-February. Estonian telephone bills are not itemised, but it is possible to ask for a printout of the calls made (most of the times for an additional fee).
