Millions of smartphone users will know today if unlimited data plans will disappear in Hong Kong, as new rules come into play.
Four of the city's five telecoms service providers are set to make announcements. SmarTone has already said it will stop offering unlimited plans to new customers.
It is likely that CSL and PCCW will also end unlimited plans. CSL - which oversees One2Free and 1010 - said it was considering eliminating the option and might announce details today. PCCW has removed the option from its leaflets, and is promoting 100 megabyte, 800MB and 5 gigabyte plans instead.
3HK has not spelled out its position, while China Mobile never offered genuinely unlimited plans - the company limits or suspends data services for that billing month when a client uses more than 5GB of data.
All of the companies are making changes in order to meet the Office of the Telecommunications Authority's (Ofta) Fair Usage Policy Guidelines, which take effect today.
From today, service providers offering 'unlimited' plans must ensure they offer the service free of restrictions. If limits are necessary, the provider should consider offering plans with a high-usage cap.
