Currently in pakistan have a huge market of free apps in smart mobile phones so lot of free features in these applications like facebook, skype IMO & other free applications of socila market.
all these apps have free voice calling service provides to users, but because of these features have loss to PTA.
so the government decide to these applications must purchase a license to run these apps in pakistan other wise they will block these service in pakistan. date and schedule of block the services is not confirmed now but pakistani apps users are very disappointed to hear this news because its must be take some time to purchasing license by these companies one by one & many chances that these companies do not want to purchase these billions cost license to run there apps in pakistan.
because of this time duration spart phone mobile market goes definitely down because large number of pakistani users is only using mobile for these apps only.
