Catalysis of the hydrolysis of phosphoric monoesters, releasing inorganic phosphate. Catalysis of the removal of a phosphate group from phosphorylated myo-inositol (1,2,3,5/4,6-cyclohexanehexol) or a phosphatidylinositol. Catalysis of the removal of one of the three phosphate groups of an inositol trisphosphate. Catalysis of the reaction: D-myo-inositol 1,3,4-trisphosphate + H2O = myo-inositol 1,3-bisphosphate + phosphate. Catalysis of the reactions: D-myo-inositol 1,4,5-trisphosphate + H2O = myo-inositol 1,4-bisphosphate + phosphate, and 1D-myo-inositol 1,3,4,5-tetrakisphosphate + H2O = 1D-myo-inositol 1,3,4-trisphosphate + phosphate.
