The National Broadcasting and Telecommunications Commission gave the order last Friday.

AWN has yet to finish transferring 300,000 subscribers who have asked to be moved to True while retaining their existing phone numbers. Most of these subscribers made the number-portability requests at 7-Eleven convenience stores.

AWN and Total Access Communication’s subsidiary DTAC TriNet have complained to the NBTC that requests for phone-number portability at 7-Elevens went against the commission’s regulation governing number portability. But the NBTC ruled that it did comply with the rules.

DTAC has reported to the NBTC that it has already filed all the request orders for transfers to True’s network, while AWN has said some 300,000 requests remain, citing the lack of some required information from these subscribers.

The NBTC then decided to fine AIS alone.

The NBTC’s order came while AIS and True have still not cleared up two issues before the new auction for a 900-megahertz licence takes place on May 27.

One relates to mobile-number portability via 7-Eleven convenience stores and the other to the possibility of AIS roaming its second-generation-cellular subscribers on True’s 900MHz network.

Only AWN and True Move H Universal Communication of True Corp have picked up the bidding documents for the 900MHz licence auction.

The period for returning the completed package to the NBTC runs from April 12 to May 17.

DTAC has already said it won’t be bidding for the licence.
