It is likely that the contact information they're using to find you doesn't match what you set for yourself and/or your privacy is higher. However, directly responding to the conversation should always work! :) ✳ TIP: IF YOU GET AN "INBOX FULL" message, there's no need to delete the app or messages: This just means that your friend has to listen or reply to the messages you sent before you can continue to send them messages. Once they listen or respond, you can keep on talking!NOTE THAT CARRIERS MAY CHARGE YOU & YOUR RECIPIENT FOR SMS INVITES, but they're not required--email invites and direct connections to other HeyTell users using phone, email, Twitter, & Facebook are free!Problems/questions? - Email us at email@example.com! - Follow us on Twitter @ https://twitter.com/heytell- "Like" us on Facebook at https://facebook.com/heytell!- Circle us on G+ at http://www.heytell.com/+!
