After a poor February, Hong Kong's cellular industry witnessed something of a rebound in March. Government figures show 63,000 new subscribers were added in the month. By comparison, new additions in February were only about 26,000. Most of last year showed monthly net additions of 100,000. Of particular interest to longer-established operators with GSM, D-AMPS and CDMA services using the 800/900 MHz frequency was the recovery in that sector. February showed a net loss of subscribers, whereas March recorded a 39,000 surge in new customers - equivalent to a 2 per cent increase. PCS services, which use the 1800 MHz frequency, continue to be the main engine of growth. There were 24,700 new customers recorded in March, equivalent to a 7.8 per cent rise in numbers. Adding to the voice mailbox function, SmarTone has introduced the concept of the fax mailbox. According to the publicity blurb the service 'provides a seamless connect between the mobile phone and fax communication'. It means customers can receive faxes on their handsets, store the data in the 'fax mailbox' and print out at any fax machine at a later date. The service carries a monthly fee of $50. Charges paid by Internet users to Hongkong Telecom for using its lines are set to fall. After a review, the industry regulator, the Office of the Telecommunications Authority (Ofta), has announced that the so-called Pnets charge will fall by 21 per cent from 4.2 cents per minute to 3.3 cents per minute. While Hong Kong's local voice calls are free, the Pnets charge is levied as a way of compensating Hongkong Telecom for Internet usage. Typically, an Internet service provider (ISP) will charge its customers a flat monthly rate for unlimited Internet access but will pass on the Pnets charge to its customers. 'An access charge of less than $2 per hour for our Internet users is among the lowest in the world, said director-general of the Telecommunications Authority Anthony Wong.
