Well - Google Messages my use additional communication protocols even
for SMS. So when it gets an SMS it may check if the sender is also
connected to the Google messaging network which apps can use to exchange
any kind information of the internet (also known as Firebase Cloud
Messaging) and use that as an additional way of transmitting information
to each other.
