Deprived of Google Hangouts support SMS
Messenger Hangouts in March turned into two apps: Hangouts and Hangouts Chat Meet, represent the tools for collective communication.
For those who continued to use older versions of Hangouts, there is another good reason to move ON. The fact that Hangouts stopped supporting sending and receiving SMS. The exceptions are users of Project Fi and Google Voice — they support SMS stored.
Note that the messenger Allo, which is partly replaced Hangouts also supports SMS and it is unclear whether or when any such function. The Google at the moment not offering a single application that would integrate the message of the messenger and SMS.
