EXHIBIT 31.1

                                 CERTIFICATIONS

I, Michael J. Zwebner, certify that:

1. I have reviewed this quarterly report on 10-QSB of Universal Communication
Systems, Inc.;

2. Based on my knowledge, this quarterly report does not contain any untrue
statement of a material fact or omit to state a material fact necessary to make
the statements made, in light of the circumstances under which such statements
were made, not misleading with respect to the period covered by this quarterly
report;

3. Based on my knowledge, the financial statements, and other financial
information included in this quarterly report, fairly present in all material
respects the financial condition, results of operations and cash flows of the
registrant as of, and for, the periods presented in this quarterly report;

4. The registrant's other certifying officer and I are responsible for
establishing and maintaining disclosure controls and procedures (as defined in
Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over financial
reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the
registrant and we have:

   a)  Designed such disclosure controls and procedures, or caused such
       disclosure controls and procedures to be designed under our supervision,
       to ensure that material information relating to the registrant, including
       its consolidated subsidiaries, is made known to us by others within those
       entities, particularly during the period in which this quarterly report
       is being prepared;

   b)  Designed such internal control over financial reporting, or caused such
       internal control over financial reporting to be designed under our
       supervision, to provide reasonable assurance regarding the reliability of
       financial reporting and the preparation of financial statements for
       external purposes in accordance with generally accepted accounting
       principles;

   c)  Evaluated the effectiveness of the registrant's disclosure controls and
       procedures and presented in this quarterly report our conclusions about
       the effectiveness of the disclosure controls and procedures, as of the
       end of the period covered by this quarterly report based on such
       evaluation; and

   d)  Disclosed in this quarterly report any change in the registrant's
       internal control over financial reporting that occurred during the
       registrant's most recent fiscal quarter (the registrant's fourth fiscal
       quarter in the case of an annual report) that has materially affected, or
       is reasonably likely to materially affect, the registrant's internal
       control over financial reporting; and

5. The registrant's other certifying officer and I have disclosed, based on our
most recent evaluation of internal control over financial reporting, to the
registrant's auditors and the audit committee of registrant's board of directors
(or persons performing the equivalent function):

   a)  All significant deficiencies and material weaknesses in the design or
       operation of internal controls are reasonably likely to adversely affect
       the registrant's ability to record, process, summarize and report
       financial information; and

   b)  Any fraud, whether or not material, that involves management or other
       employees who have a significant role in the registrant's internal
       controls.
