Since its global launch, Pokemon Go has sparked a worldwide frenzy among users who have taken to the streets with their smartphones.
The viral game uses satellite locations, graphics and camera capabilities to overlay cartoon monsters onto real-world settings, challenging players to capture and train the creatures for battles.
Some autocratic countries such as Iran have even banned the game.
Pramoth Sudjitporn, chief executive of SET-listed Asiasoft Corporation, the online entertainment leader in Southeast Asia, said he thought Pokemon Go would be a big hit among hundreds of thousands of first-time mobile game players.
"It might be time now for smartphone owners with 18-24 months of use to replace their phones in the wake of Pokemon Go," he said.
