Fading Ukrainian network operator Intertelecom has announced the latest step in its phasing-out of CDMA-based services, confirming on its website that it will cease CDMA voice telephony services in 13 regions on 1 July 2021, namely Vinnitsia, Zhytomyr, Kiev oblast, Kiev city, Kirovograd, Mykolaiv, Poltava, Sumy, Kharkiv, Kherson, Khmelnytsky, Cherkasy and Chernihiv. Internet/data services will not be affected. TeleGeography notes that from July, Odessa will be Intertelecom’s sole region with full CDMA voice and data service coverage (with the operator already scheduled to decommission its CDMA network in Dnipropetrovsk and Zaporozhye regions on 1 May).
Intertelecom has struck an agreement with nationwide telco Ukrtelecom to re-register CDMA telephony users’ phone numbers in the above 13 named regions to Ukrtelecom’s GSM/3G-based fixed telephony service on an opt-in basis, requiring a suitable handset, allowing customers to continue using an existing regional/district telephone number. TeleGeography’s GlobalComms Database says that Ukrtelecom’s hybrid fixed-wireless telephony service uses its subsidiary TriMob’s national roaming arrangement with Vodafone Ukraine.
As an alternative option, Intertelecom is promoting its own VoIP-based SIP telephony service which also provides regional/district telephony numbering services, enabling voice subscribers to make and receive calls via the internet to any phone numbers using a smartphone or other devices including PCs/laptops and tablets.
