Mobile (Cellular) Phones
No permission or declaration is required to bring a mobile (cellular) phone into Russia or to use one.
There are very good mobile communication networks in St. Petersburg operated by various GSM providers. If you intend to use your existing phone and SIM card first check that your provider has an international roaming agreement with one of them, and ensure you have international roaming enabled.
Please note that the majority of mobile phones in Russia operate on a GSM 900 band network. Numerous mobile phones are multi-band and automatically detect and select the required one but visitors from US and Japan that have problems can rent mobiles from various enterprises, or for longer term it may be more cost effective to purchase a phone and SIM card package.
Purchasing a local SIM card is relatively simple - the
difficulty comes in choosing a package offered by the providers.
Providers are fiercely
competing for more customers and almost continually change
prices and packages to challenge their rivals.
