As many as 31 million smartphone users in India are expected to upgrade to 5G phones between now and December, a report by Ericsson said on Tuesday, underscoring the accelerated pace at which the world's second-largest telecom market is adopting ultra-high-speed services. Ericsson estimates the current base of 5G handset users in India to be between 80 and 100 million. 5G services were launched in India in October last year by Prime Minister Narendra Modi, and the past months have seen a rapid rollout of these services across the length and breadth of the country by operators like Reliance Jio and Bharti Airtel. Swedish telecom maker Ericsson's Consumer Lab's Global Survey released on Tuesday pointed out that 5G users in India stand out for their high-quality daily engagement with apps, such as streaming high-definition video, video calling services, mobile gaming, and augmented reality.
