Catalysis of the hydrolysis of phosphoric monoesters, releasing inorganic phosphate. Catalysis of the reaction: a phospholipid + H2O = a lipid + phosphate. Catalysis of the reaction: 1-phosphatidyl-1D-myo-inositol 3-phosphate + H2O = 1-phosphatidyl-1D-myo-inositol + phosphate. Catalysis of the removal of a phosphate group from phosphorylated myo-inositol (1,2,3,5/4,6-cyclohexanehexol) or a phosphatidylinositol.
