The Bangkok Post writes that Advanced Info Service (AIS) says it will postpone the commercial launch of 3G mobile services in Bangkok until mid-July, from a previous date of mid-June, as the National Telecommunications Commission (NTC) is behind schedule in approving W-CDMA/HSDPA equipment imports. Thailand’s largest mobile operator launched a small-scale commercial 3G service in Chiang Mai earlier this month over 900MHz infrastructure. AIS is charging THB3 (USD0.09) per minute for a video call and THB1 per 5MB of data downloading. AIS has admitted that the network will only support a small number of data users due to limited bandwidth, whilst availability of 3G-capable handsets is currently limited. An AIS spokesperson stated, ‘We don’t expect much revenue from 3G now. We just want to raise awareness of 3G in Thailand.’ It is hoped that the NTC will issue 2100MHz UMTS licences later this year.
