Benefits of VoLTE for T2 Customers
T2 reported that it began the large-scale rollout of this technology in August, initially covering two regions with VoLTE. In September, it expanded to six additional regions, and in the first three weeks of October, it added another fifteen.
VoLTE allows users to make high-quality voice calls over 4G without interrupting internet access or using mobile data. It also improves call setup times, voice clarity, and battery life by eliminating the need to switch to 2G/3G, T2 explained.
