The handset is the weakest part of the phone, because it gets touched the most and dropped the most. They don't last forever.
Until the mid-1980s, about six handset types could be used on hundreds of different types of phones. Today, there are hundreds of different types of handsets. It's impossible for any dealer to have all of them, but we have some of them; and we'll be adding more.
Please DON'T order a handset just because it looks like the one you have. Read the descriptions.
