As ALMA is in full operational mode, the SMA continues to be a most valuable asset in submillimeter wavelength astronomy. In particular, for wide-field imaging, for polarization studies, and for large spectral scans, the SMA is competitive especially for the northern skies. Starting in 2017, the ASIAA invites all astronomers in the East Asian regions to join in the access to the SMA as part of an initiative within the East Asian Observatory. In this talk, we will show current capabilities and future plans for improvement in sensitivity.
