There are two types of mobile phone numbers in Odesa – direct numbers (which do not differ from the Odesa fixed line numbers, and may be dialled as such) and mobile numbers (these should be preceded by 0 and the operator’s code). SMS may not be sent to direct numbers. Mobile phone calls in Ukraine are relatively cheap and very reliable. You do not need to sign a contract or show your documents to use the local provider’s service. SIM cards are available in special service centres, mobile phone stores and even on the streets. You can also buy cards to refill your account at these same locations.
