Realme India CEO Madhav Sheth confirmed on Twitter that the company is looking for a global launch of 5G smartphones in 2019 and also said that 5G Realme phones will launch in India 'as early as possible'. 5G networks in India and across the world are expected to complete deployment only in 2020 so it is not yet clear as to what are the immediate target markets for Realme's 5G launch this year.
