SINGAPORE - The Pokemon Go craze reached Singapore's shores five days ago, but it is too early to tell if mobile subscribers here will bust their data caps as they go round the island hunting pocket monsters and hatching virtual eggs.

"For Pokemon Go, if you really look at it, it's not really a high data-generating app, because you're just sending small uploads," said Mr Yuen Kuan Moon, Singtel's chief executive of consumer business in Singapore during the telco's first quarter results briefing on Thursday (Aug 11) morning.

Singtel group chief executive Chua Sock Koong added that it is "too early to comment" on how the launch of the augmented reality game here would affect customers' data usage.

But OCBC Investment Research analyst Carey Wong expects Pokemania to raise players' data consumption by 300-500MB a month as the app has also stoked increased activity on social media.

"Instagram is full of Pokemon pictures, so is my Facebook feed. With this younger generation they don't just catch Pokemon, they share the pictures on social media," Mr Wong told the Straits Times. "I've got friends who have busted their data caps already."

StarHub said in a separate statement that the Pokemon Go app alone consumes about 20MB for every hour of play.

"While it would be too early to come to a conclusion on mobile traffic, we know that Pokemon Go is not a mobile data hog," said StarHub corporate communications senior executive Philemon Foo, who added that he was undeniably the rarest Pokemon.
