When you are in St Petersburg you can call from where you stay or use public phones. To use a public phone you will need a coin or a phone card you can buy from post offices or numerous newsstands. If you decide to stay for a week or more, perhaps, it is better to connect to one of Russia's mobile phone networks. St Petersburg is a big city and a phone at hand may be very useful sometime. If you didn't take your mobile phone you can rent or buy new one (provided you can spend some extra money on it).

To call from St Petersburg is easy. If you need to make an international call, dial 8 + 10 + country code + city code + number. Wait for a single, not repeated, dial tone after 8 and then dial the rest.

When you need to call to another city of Russia, dial 8 + city code + number. For calling within St Petersburg you don't need to dial any additional codes.
