Can the Access Provider outright terminate an Access Agreement prior to the SKMM’ approval after notifying SKMM of the intention to terminate the agreement with the Access Seeker?

No, subsection 5.17.6 of the MSA stipulates that the Access Provider shall not terminate or suspend or seek to materially vary the Access Agreement or access to any network facilities or network services provided under it until such time and on such conditions as the SKMM may specify.
