Option 1: You can buy a new keyboard that hooks up to your phone. It'll work with the wireless Bluetooth connection the phone uses to connect to headphones, speakers, and other compatible devices. Option 2: Wi-Fi keyboards are available these days, too (usually designated by the word "wireless" in their description since they do run on batteries). Connecting them is no more difficult than connecting any other wireless device to your network router or modem. Just make sure you type in your password once you get them hooked up!
