one2free introduced Hong Kong's first 4G LTE mobile broadband service, the service provider said Wednesday.

"Our 4G LTE/DC-HSPA+ network is the world's first and offers delivers sizzling speeds and an uninterrupted user experience at the speed of Hong Kong life," said Joseph O'Konek, CEO of CSL that owns the one2free network.

According to the company, with its 4G LTE service, a 10MB file download takes 5 seconds, compared with around 25 seconds when using 3G service while an 8GB HD movie download will take less than an hour rather than around five hours with 3G.

One2free is also offering 12 months free 4G LTE mobile broadband to the first 100 customers who sign up for the two-year mobile broadband service plan dubbed Xtreme 1GB that costs HK$187 per month or 5GB that costs HK$287 per month. The special launch offer is available only from one2free Mongkok or Causeway Bay stores from 6pm on August 3, the firm added.
