The National Telecommunications Commission of the Philippines is looking at the possibility of removing the expiration of cellphone and internet prepaid loads. Although, the cards are valid for one year, the validity of the credit expires depending on the amount. Thus, consumers have to utilize the credits left before forfeiture. How will the removal of the expiration dates affect the telecommunications market?
