Send a Text
Tap the message icon to compose a new message. Enter your recipient's ten-digit phone number, or search by name if you've given Heywire permission to access your phone's contacts.
You can compose a text message with up to 500 characters, but the messages will be delivered in 160-character "chunks" to meet industry standards and make sure the full message is received.
If you have set a signature, and the signature causes your message to go over 160 characters, the signature will be dropped. Twitter can only accept 140 characters.
