I find it hard to believe that other countries dont have phone systems that ask for letters to be entered for calling or in an automated system. Pretty sure its a universal system not related to a certain country. Nokia clearly just forgot it. Because followwing that logic, ok fine, uk doesnt use it. But nokia made 2 versions of this phone. If usa is the only place that used letters then nokia would have included it for the nam version and left it out of the euro version. But they didnt even do that. They just plain forgot it.
