rMs_000: For the "Royal or star numbers", see our response on Easy-to-Remember numbers:

Numbers used for fixed and mobile services including ETR numbers will have a new digit, ETR are not part of the national numbering plan. Customers purchased ETRs should contact their service providers, call the Helpline of Qtel and Vodafone for further information related to ETRs. Qtel customer service line can be reached by dialing 111 whilst Vodafone customers can dial 111 from their mobile phone and speak to a Customer Care Champion. If Vodafone customers are calling from another number and not their Vodafone mobile, they should dial 800 7111.
