Cell phone and SMS implementation

Is it possible to implement an SMS option in Hubspot ? A problem that I have is that Hubspot is exclusively set up for outbound calls but not inboud. I get those calls on the mobile that is linked with HubSpot, with the downside that i cannot see who is calling me, and also most of the people answer me with default SMS like i cannot talk or call me later and expect me to answer but i can't. Is it possible to add this feature to hubspot?
