, From today, all Zain customers (pre-paid and post-paid) in Africa and the Middle East using ‘One Network’ will enjoy the benefits of being treated as a ‘local’ customer wherever they are. Customers can make calls and send messages at local rates when communicating with a travelling Zain customer who will receive incoming calls free-of-charge and be able to make calls back home at local rates. Pre-paid customers can also top up their phones with recharge cards bought from either their home country or more than one million outlets available in one of the 15 One Network countries. The One Network service is automatically activated upon crossing the geographic border into one of the countries, with no prior registration required or sign-up fee, www.zain.com
