That is an increase from the current 7 percent royalty paid by Oman Telecommunications (Omantel) and Ooredoo Oman, the companies said in bourse statements.
Omantel said a rate of 12 percent would have cost the company an additional 16 million rials ($41.6 million) in the first nine months of this year. It made a net profit of 95.1 million rials in that period.
Ooredoo Oman, majority owned by Qatar's Ooredoo, said the higher rate would have cost it 8.7 million rials over the same period, or 23.3 percent of its net income.
