YouMail utilizes a carrier feature called Conditional Call Forwarding (CCF) to receive your missed calls and connect you to our system.
To set up YouMail on Cricket Wireless: Press **004* followed by your YouMail deposit number and # symbol. Note that you can locate your deposit number that you forward to on our website: https://www.youmail.com/youmail/user/phones
Once you have dialed the deposit number into your phone press "SEND" and wait for a confirmation tone or message.
For example, if your YouMail deposit number is 555-555-5555, the activation number you would be required to dial and call is:
**004*555-555-5555#
Try test calls afterwards to see if YouMail picks up.
