Catalysis of the reaction: RPO-R' + H2O = RPOOH + R'H. This reaction is the hydrolysis of any phosphoric ester bond, any ester formed from orthophosphoric acid, O=P(OH)3. Catalysis of the hydrolysis of phosphoric monoesters, releasing inorganic phosphate. Catalysis of the reaction: myo-inositol hexakisphosphate + H2O = D-myo-inositol 1,2,4,5,6-pentakisphosphate + phosphate.
