Google bundled phone calls, SMS, MMS, IM and video into one application, it was also initially dependent on Google Plus which was later separated. It has no association with an SIM, but with email. On a mobile device it is cumbersome, and by the time that Google Plus was moved to its own designated app the larger user base moved to the competition where SIM association was more acceptable to the market.
