Once you have entered your username and password, the cambioApp asks for a 6-digit code. We sent it to you by text message from sender 8810 or 8850.
Did you not receive a text message? Did you provide a mobile phone number when you registered? Did you enter the correct mobile phone number? Check your phone number on Mycambio. Log in with username and password and adjust if necessary.
Contact customer service if it doesn't work.
