The unlimited text messaging and voice call promotions of both Smart and Globe will be temporarily suspended this holiday season, the Philippines’ National Telecommunications Commission (NTC) said.

The move was undertaken apparently to prevent network abuse during Christmas and New Year, the time when text messages and voice calls are expected to double, the NTC added.

Globe and Touch Mobile’s (TM) unlimited night calls will not be in effect starting 11 in the evening of December 30 up to six in the morning of January 1, 2009 while Smart’s All Text Combo with Unlimited Night Calling Promo will not be available on December 30, 31 and January 1, 2009.

Meanwhile, the top officials of the NTC, Smart Communications Inc., and Globe Telecom Inc. are facing a congressional inquiry for the purported suspension of call-and-text promo packages at the peak of the holiday season.
