Issues receiving text messages
Is your contact sending you a text message from an international number?
Are you trying to receive a text message from a website (i.e. Skype, Chase, Facebook, etc.)?
Is the sender receiving an error when trying to send a text message to your Google number?
Has this resolved your issue?
Did you recently port your in to Google Voice (this is NOT related to the Google Voice Sprint Integration, but rather you would have paid $20 to port your number into Google Voice)?
Did this resolve your issue?
