Is their a mobile phone that translates one language to another? it would help tremendously in business?

When I call customers in Europe they mostly do not speak English, what if they can speak their own country's language and the mobile phone automatically translates their language into English; and Vice Versa I speak in English and they hear it as if its their own language. what do u think?|||I'm 100% sure that the Android and iPhone have apps that read your voice and translate them to another language in text.
