DUBAI, Oct 5 (Reuters) - Saudi Arabia's top three telecommunication operators suffered mixed fortunes on Wednesday after all three had risen in heavy trade the previous day while other markets in the region sagged.
Mobile Telecommunication Company (Zain KSA) jumped 6.8 percent, taking its gains since Sunday to 17 percent. Its chief competitor Saudi Telecom (STC) retreated 2.8 percent on Wednesday morning and Etihad Eisalat was down 1.3 percent.
On Sunday the government said it will provide operators with "unified licences" allowing them to offer a full range of telecommunications services.
Telecommunications analysts said this represented a major shake-up of the industry and that there could be losers as well as winners.

The contract period will be nine months, with the financial impact staring to be reflected in the fourth quarter results.
