Saudi Arabia's three mobile network operators, STC, Etihad Etisalat (Mobily) and Zain Saudi, have signed an agreement to allow their customers to switch their telephone numbers from one company to another, Arab News has reported. The agreement facilitates the number transfer, a process known as porting, upon the payment of the required fee. However, a number cannot be ported within two months after it is issued.
