Communication services provider EE has announced plans to improve phone call services after raising £275m of funding during 2014.
Under the plans, the UK-based company will upgrade 5,000 2G sites and double the call handling capacity of about 5,500 3G sites, providing better voice call quality and reliability.
EE will also conduct test for future call services including 4G voice (VoLTE) and voice over Wi-Fi under the plans.
EE CEO Olaf Swantee said the UK mobile industry can do better, and the company intends to improve the experience for its customers, taking quality and reliability to levels to those achieved by other operators across Europe.
"This year, we have been focusing a large amount of our activity and investment on offering consumers the most reliable, highest quality phone call experience," Swantee added.
According to the company, it has reached the highest ever call success rate of 99.2% as well as handling over one billion calls every week.
"For the majority of our customers, being able to make a phone call when they need to is still the vital aspect of the mobile experience.
"Innovative, high-speed data services receive most of the attention in the mobile industry as they are changing the way people communicate, connect, trade and interact.
"That's why we plan to invest £275m in our voice call service in 2014 as we strive to set new standards in call quality and reliability."
Previously, the company had upgraded 2G equipment across 6,000 sites with the latest technology to reduce dropped calls by 50%.
