Apple sued by user over iPhone charges

Apple was sued by a customer who says he incurred hidden high roaming fees on his iPhone while traveling internationally because of Apple’s exclusive contract with AT&T.

Herbert Kliegerman, who seeks to represent other iPhone purchasers in a class action, was charged $2,000 in international roaming fees after using his $599 iPhone for seven days in Mexico, he said in a complaint filed in state court in Manhattan.

Because of Apple’s contract with AT&T, the iPhone cannot be used with a foreign wireless carrier while overseas, which would cost less, he said in his complaint. Apple did not adequately disclose that restriction before Kliegerman bought three of the phones, he claims in his lawsuit.
