Turkcell, the leading mobile operator in Turkey in terms of subscribers, has chosen TeliaSonera International Carrier (TSIC) to enable 4G roaming with 31 operators across 29 countries. TSIC’s IPX-based diameter signalling service allows Turkcell’s more than 34.5 million users to access 4G services when roaming in selected countries, while TSIC subscribers can connect to 4G in Turkey via in-bound roaming. Matthew Jones, head of mobile solutions at TSIC, commented: ‘[I’m] impressed with how our teams worked together to enable a 4G roaming service for a non-4G network operator … It’s a first for TSIC and Turkcell.’

As previously reported by TeleGeography’s CommsUpdate, a multi-band spectrum auction is expected to be held in Turkey on 26 May 2015, paving the way for the introduction of commercial 4G LTE technology in the country by year-end.
