PTA Director-General Muhammad Talib Dogar has ordered telecom companies to cease offering voice and text messaging bundle packages at any and all times of the day by September 2.
"We had sent the telecom companies a letter in November, 2012 to comply with but they have still not complied and are offering these packages," a PTA official confirmed.
The packages offered by the telecom companies have come under fire in the National Assembly, with some members terming the packages as being against the moral values of Pakistani society.
In the last five years Pakistan has seen a boom in the cellular industry with the number of mobile phone users increasing dramatically.
A senior official of a telecom company said the PTA decision is likely to create ripples across the sector and provide further strain to an industry already overburdened with heavy taxation.
