     The undersigned acknowledges that he or she has received and reviewed the
Prospectus and Consent Solicitation dated November 5, 1999 (the "Prospectus"),
of World Access, Inc., a Delaware corporation (the "Company"), and this Letter
of Transmittal (the "Letter"), which together constitute the Company's
solicitation of your consent to amend the indenture governing the FaciliCom
Notes as more fully described in the Prospectus and the Company's offer (the
"Exchange Offer") to exchange for up to $300,000,000 aggregate principal amount
of FaciliCom Notes the following consideration (the "Exchange Consideration"):
(i) a like principal amount of its 13.25% Senior Notes due 2008 (the "Exchange
Notes"), (ii) shares of the Company's common stock, par value $0.01 per share,
having a market value of $50 for each $1,000 principal amount of FaciliCom Notes
tendered and accepted for exchange (the "Exchange Shares") and (iii) a payment
of $10 in cash for each $1,000 principal amount of FaciliCom Notes tendered and
accepted for exchange (the "Cash Payment").

     The undersigned has completed the appropriate boxes above and below and
signed this Letter to indicate the action the undersigned desires to take with
respect to the Exchange Offer.

     This Letter is to be used either if certificates for FaciliCom Notes are to
be forwarded herewith or if delivery of FaciliCom Notes is to be made by
book-entry transfer to an account maintained by the Exchange Agent at The
Depository Trust Company, pursuant to the procedures set forth in "The Exchange
Offer -- Procedures for Tendering" in the Prospectus. Delivery of this Letter
and any other required documents should be made to the Exchange Agent. Delivery
of documents to a book-entry transfer facility does not constitute delivery to
the Exchange Agent.

     Holders whose FaciliCom Notes are not immediately available or who cannot

Exchange Agent on or prior to the Expiration Date must tender their FaciliCom
Notes according to the guaranteed delivery procedure set forth in the Prospectus

              PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

     Upon the terms and subject to the conditions of the Exchange Offer, the
undersigned hereby tenders to the Company the aggregate principal amount of
FaciliCom Notes indicated above. Subject to, and effective upon, the acceptance
for exchange of the FaciliCom Notes tendered hereby, the undersigned hereby
sells, assigns and transfers to the Company all right, title and interest in and
to such FaciliCom Notes as are being tendered hereby.

     The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, sell, assign and transfer the FaciliCom
Notes tendered hereby and that the Company will acquire good and unencumbered
title thereto, free and clear of all liens, restrictions, charges and
encumbrances and not subject to any adverse claim when the same are accepted by
the Company. The undersigned will, upon request, execute and deliver any
additional documents deemed by the Company or the Exchange Agent to be necessary
or desirable to complete the sale, assignment and transfer of the FaciliCom
Notes tendered hereby.

     If the undersigned is not a broker-dealer, the undersigned represents that
(i) the Exchange Notes and Exchange Shares acquired pursuant to the Exchange
Offer are being obtained in the ordinary course of business of the person
receiving such Exchange Notes and Exchange Shares, whether or not such person is
the holder, (ii) such holder or such other person has no arrangement or
understanding with any person to participate in the distribution of such
Exchange Notes or Exchange Shares within the meaning of the Securities Act and
is not participating in, and does not intend to participate in, the distribution
of such Exchange Notes or Exchange Shares within the meaning of the Securities
Act, and (iii) such holder or such other person is not an "affiliate," as
defined in Rule 405 under the Securities Act, of the Company or, if such holder
or such other person is an affiliate, such holder or such other person will
comply with the registration and prospectus delivery requirements of the
Securities Act to the extent applicable.

     If the undersigned is a broker-dealer which will receive Exchange Notes or
Exchange Shares for its own account in exchange for FaciliCom Notes that were
acquired as a result of market-making activities or other trading activities, it
may be deemed to be an "underwriter" within the meaning of the Securities Act
and it acknowledges that it will deliver a prospectus meeting the requirements
of the Securities Act in connection with any resale, offer to resell or other
transfer of such Exchange Notes or Exchange Shares; however, by so acknowledging
and by delivering a prospectus, the undersigned will not be deemed to admit that
it is an "underwriter" within the meaning of the Securities Act.

     All authority conferred or agreed to be conferred in this Letter and every
obligation of the undersigned hereunder shall be binding upon the successors,
assigns, heirs, executors, administrators, trustees in bankruptcy and legal
representatives of the undersigned and shall not be affected by, and shall
survive, the death or incapacity of the undersigned. This tender may be
withdrawn only in accordance with the procedures set forth in the instructions
contained in this Letter.

     The undersigned understands that tenders of the FaciliCom Notes pursuant to
any one of the procedures described under "The Exchange Offer -- Procedures for
Tendering" in the Prospectus and in the instructions hereto will constitute a
binding agreement between the undersigned and the Company in accordance with the
terms and subject to the conditions of the Exchange Offer.

     The undersigned recognizes that, under certain circumstances set forth in
the Prospectus under "The Exchange Offer -- Certain Conditions to the Exchange
Offer," the Company may not be required to accept for exchange any of the
FaciliCom Notes tendered. FaciliCom Notes not accepted for exchange or withdrawn
will be returned to the undersigned at the address set forth below unless
otherwise indicated under "Special Delivery Instructions" below.

     Unless otherwise indicated herein in the box entitled "Special Issuance
Instructions" below, please issue the Exchange Consideration (and, if
applicable, substitute certificates representing FaciliCom Notes for any
FaciliCom Notes not exchanged) in the name of the undersigned. Similarly, unless
otherwise indicated under the box entitled "Special Delivery Instructions"
below, please deliver the Exchange Consideration (and, if applicable, substitute
certificates representing FaciliCom Notes for any FaciliCom Notes not exchanged)
to the undersigned at the address shown above in the box entitled "Description
of FaciliCom Notes."

     The undersigned, by completing the box entitled "Description of FaciliCom
Notes" above and signing this Letter and delivering such notes and this Letter

                                  INSTRUCTIONS

         FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER

     1. DELIVERY OF THIS LETTER AND FACILICOM NOTES; GUARANTEED DELIVERY
PROCEDURE.  This Letter is to be used to forward, and must accompany, all
certificates representing FaciliCom Notes tendered pursuant to the Exchange
Offer unless such certificates are accompanied by an Agent's Message (as defined
below) in which case you need not submit this Letter to the Exchange Agent.
Certificates representing the FaciliCom Notes in proper form for transfer (or a
confirmation of book-entry transfer of such FaciliCom Notes into the Exchange
Agent's account at the book-entry transfer facility) must be received by the
Exchange Agent at its address set forth herein on or before the Expiration Date.
A tender will not be deemed to have been timely received when the tendering
holder's properly completed and duly signed Letter or an Agent's Message
accompanied by the FaciliCom Notes is mailed prior to the Expiration Date but is
received by the Exchange Agent after the Expiration Date.

     The term "Agent's Message" means a message transmitted by The Depository
Trust Company ("DTC") to, and received by, the depositary and forming a part of
a Book-Entry Confirmation, which states that DTC has received an express
acknowledgment from the participant in DTC tendering the FaciliCom Notes, that
such participant has received and agrees to be bound by the terms of this Letter
and the Company may enforce such agreement against the participant.

     The method of delivery of this letter, the FaciliCom Notes and all other
required documents is at the election and risk of the tendering holders, but the
delivery will be deemed made only when actually received or confirmed by the
exchange agent. If such delivery is by mail, it is recommended that registered
mail properly insured, with return receipt requested, be used. In all cases,
sufficient time should be allowed to permit timely delivery.

     If a holder desires to tender FaciliCom Notes and such holder's FaciliCom
Notes are not immediately available or time will not permit such holder's Letter
of Transmittal, FaciliCom Notes (or a confirmation of book-entry transfer of
FaciliCom Notes into the Exchange Agent's account at the book-entry transfer
facility with an Agent's Message) or other required documents to reach the
Exchange Agent on or before the Expiration Date, such holder may still tender in
the Exchange Offer if:

        (a) the tender is made through an Eligible Institution (as defined
            below);

        (b) prior to the Expiration Date, the Exchange Agent receives from such
            Eligible Institution a properly completed and duly executed Letter
            of Transmittal (or facsimile thereof) and Notice of Guaranteed
            Delivery, substantially in the form provided by us (by facsimile
            transmission, mail or hand delivery), setting forth the holder's
            name and address as holder of the FaciliCom Notes and the amount of
            FaciliCom Notes tendered, stating that the tender is being made
            thereby and guaranteeing that within three Nasdaq trading days after
            the Expiration Date the certificates for all physically tendered
            FaciliCom Notes, in proper form for transfer, or a book-entry
            confirmation with an Agent's Message, as the case may be, and any
            other documents required by the Letter of Transmittal will be
            deposited by the Eligible Institution with the Exchange Agent; and

        (c) the certificates for all physically tendered FaciliCom Notes, in
            proper form for transfer, or a book-entry confirmation as the case
            may be, and all other documents required by this Letter of
            Transmittal are received by the Exchange Agent within three Nasdaq
            trading days after the Expiration Date.

     See "The Exchange Offer -- Procedures for Tendering" in the Prospectus.

     2. WITHDRAWALS.  Any holder who has tendered FaciliCom Notes may withdraw
the tender by delivering written notice of withdrawal (which may be sent by
telegram, facsimile (receipt confirmed by telephone and an original delivered by
guaranteed overnight courier)) to the Exchange Agent prior to the close of
business on the Expiration Date and prior to acceptance for exchange thereof by
us. For a withdrawal to be effective, a written notice of withdrawal must (i)
specify the name of the person having tendered the FaciliCom Notes to

                                        8
   9

be withdrawn (the "Depositor"), (ii) identify the FaciliCom Notes to be
withdrawn (including the certificate number or numbers and principal amount of
such FaciliCom Notes), (iii) be signed by the holder in the same manner as the
original signature on the Letter by which such FaciliCom Notes were tendered or
as otherwise set forth in Instruction 3 below (including any required signature
guarantees), or be accompanied by documents of transfer sufficient to have the
trustee for the FaciliCom Notes register the transfer of such FaciliCom Notes
into the name of the person having made the original tender and withdrawing the
tender and (iv) specify the name in which any such FaciliCom Notes are to be
registered, if different from that of the Depositor. If FaciliCom Notes have
been tendered pursuant to the procedure for book-entry transfer, any notice of
withdrawal must specify the name and number of the participant's account at the
book-entry transfer facility to be credited, if different from that of the
Depositor, with the withdrawn FaciliCom Notes or otherwise comply with the
book-entry transfer facility's procedures. See "The Exchange Offer--Withdrawal
of Tenders" in the Prospectus.

     3. SIGNATURES ON THIS LETTER; BOND POWERS AND ENDORSEMENTS; GUARANTEE OF
SIGNATURES.  If this Letter is signed by the registered holder of the FaciliCom
Notes tendered hereby, the signature must correspond with the name as written on
the face of the certificates without alteration, enlargement or any change
whatsoever.

     If this Letter is signed by a participant in DTC, the signature must
correspond with the name as it appears on the security position listing as the
holder of the FaciliCom Notes.

     If this Letter or any FaciliCom Notes or bond powers are signed by
trustees, executors, administrators, guardians, attorneys-in-fact, officers of
corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing. Unless waived by us, evidence
satisfactory to us of their authority to so act must also be submitted with the
Letter of Transmittal.

     If any tendered FaciliCom Notes are owned of record by two or more joint
owners, all such owners must sign this Letter.

     The signatures on this Letter or a notice of withdrawal, as the case may
be, must be guaranteed by a member firm of a registered national securities
exchange or of the National Association of Securities Dealers, Inc., a
commercial bank or trust company having an office or correspondent in the United
States or an "eligible guarantor" institution within the meaning of Rule 17Ad-15
under the Securities Exchange Act of 1934, as amended (each, an "Eligible
Institution"), unless the FaciliCom Notes are tendered: (i) by a registered
holder (or by a participant in DTC whose name appears on a security position
listing as the owner) who has not completed the box entitled "Special Issuance
Instructions" or "Special Delivery Instructions" on this Letter and the Exchange
Consideration is being issued directly to such registered holder (or deposited
into the participant's account at DTC), or (ii) for the account of an Eligible
Institution.

     4. SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS.  Tendering holders of
FaciliCom Notes should indicate in the applicable box the name and address to
which Exchange Consideration issued pursuant to the Exchange Offer is to be
issued or sent, if different from the name or address of the person signing this
Letter. In the case of issuance in a different name, the tax identification
number of the person named must also be indicated. If no such instructions are
given, any Exchange Consideration will be issued in the name of, and delivered
to, the name or address of the person signing this Letter and any FaciliCom
Notes not accepted for exchange will be returned to the name or address of the
person signing this Letter.

     5. BACKUP FEDERAL INCOME TAX WITHHOLDING AND SUBSTITUTE FORM W-9.  Under
the federal income tax laws, payments that may be made by the Company on account
of Exchange Consideration issued pursuant to the Exchange Offer may be subject
to backup withholding at the rate of 31%. In order to avoid such backup
withholding, each tendering holder should complete and sign the Substitute Form
W-9 included in this Letter and either (a) provide the correct taxpayer
identification number ("TIN") and certify, under penalties of perjury, that the
TIN provided is correct and that (i) the holder has not been notified by the
Internal Revenue Service (the "IRS") that the holder is subject to backup
withholding as a result of failure to report all interest or dividends or (ii)
the IRS has notified the holder that the holder is no longer subject to backup
withholding; or (b) provide an adequate basis for exemption. If the tendering
holder has not been issued a TIN and has applied for one, or intends to apply
for one in the near future, such holder should write "Applied For" in the

                                        9
   10

space provided for the TIN in Part I of the Substitute Form W-9, sign and date
the Substitute Form W-9, and sign the Certificate of Payee Awaiting Taxpayer
Identification Number. If "Applied For" is written in Part I, the Company (or
the Paying Agent under the Indenture governing the Exchange Notes) shall retain
31% of payments made to the tendering holder during the sixty (60) day period
following the date of the Substitute Form W-9. If the holder furnishes the
Exchange Agent or the Company with his or her TIN within sixty (60) days after
the date of the Substitute Form W-9, the Company (or the Paying Agent) shall
remit such amounts retained during the sixty (60) day period to the holder and
no further amounts shall be retained or withheld from payments made to the
holder thereafter. If, however, the holder has not provided the Exchange Agent
or the Company with his or her TIN within such sixty (60) day period, the
Company (or the Paying Agent) shall remit such previously retained amounts to
the IRS as backup withholding. In general, if a holder is an individual, the
taxpayer identification number is the Social Security number of such individual.
If the Exchange Agent or the Company is not provided with the correct taxpayer
identification number, the holder may be subject to a $50 penalty imposed by the
IRS. Certain holders (including, among others, all corporations and certain
foreign individuals) are not subject to these backup withholding and reporting
requirements. In order for a foreign individual to qualify as an exempt
recipient, such holder must submit a statement (generally, IRS Form W-8), signed
under penalties of perjury, attesting to that individual's exempt status. Such
statements can be obtained from the Exchange Agent. For further information
concerning backup withholding and instructions for completing the Substitute
Form W-9 (including how to obtain a taxpayer identification number if you do not
have one and how to complete the Substitute Form W-9 if FaciliCom Notes are
registered in more than one name), consult the enclosed Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9.
Tendering holders are urged to also consult their own tax advisors to determine
whether they are exempt from these backup withholding and reporting
requirements.

     Failure to complete the Substitute Form W-9 will not, by itself, cause
FaciliCom Notes to be deemed invalidly tendered, but may require the Company (or
the Paying Agent) to withhold 31% of the amount of any payments made on account
of the Exchange Consideration. Backup withholding is not an additional federal
income tax. Rather, the federal income tax liability of a person subject to
backup withholding will be reduced by the amount of tax withheld. If withholding
results in an overpayment of taxes, a refund may be obtained.

     6. TRANSFER TAXES.  The Company will pay all transfer taxes, if any,
applicable to the transfer of FaciliCom Notes to it or its order pursuant to the
Exchange Offer. If, however, Exchange Consideration and/or substitute FaciliCom
Notes not exchanged or accepted for exchange are to be delivered to, or are to
be registered or issued in the name of, any person other than the registered
holder of the FaciliCom Notes tendered hereby, or if tendered FaciliCom Notes
are registered in the name of any person other than the person signing this
Letter, or if a transfer tax is imposed for any reason other than the transfer
of FaciliCom Notes to the Company or its order pursuant to the Exchange Offer,
the amount of any such transfer taxes (whether imposed on the registered holder
or any other persons) will be payable by the tendering holder. If satisfactory
evidence of payment of such taxes or exemption therefrom is not submitted
herewith, the amount of such transfer taxes will be billed directly to such
tendering holder.

     7. WAIVER OF CONDITIONS.  Conditions enumerated in the Prospectus may be
waived by the Company, in whole or in part, at any time from time to time in its
reasonable discretion.

     8. NO CONDITIONAL TENDERS.  No alternative, conditional, irregular or
contingent tenders will be accepted. All tendering holders of FaciliCom Notes,
by execution of this Letter, shall waive any right to receive notice of the
acceptance of their FaciliCom Notes for exchange.

     Neither the Company nor any other person is obligated to give notice of
defects or irregularities in any tender, nor shall any of them incur any
liability for failure to give any such notice.

     9. INADEQUATE SPACE.  If the space provided herein is inadequate, the
aggregate principal amount of FaciliCom Notes being tendered and the certificate
number or numbers (if available) should be listed on a separate schedule
attached hereto and separately signed by all parties required to sign this
Letter.

                                       10

     10. MUTILATED, LOST, STOLEN OR DESTROYED FACILICOM NOTES.  If any
certificate has been lost, mutilated, destroyed or stolen, the holder should
promptly notify First Union National Bank at the telephone number indicated
above. The holder will then be instructed as to the steps that must be taken to
replace the certificate(s). This Letter of Transmittal and related documents
cannot be processed until the FaciliCom Notes have been replaced.

     11. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Questions relating to
the procedure for tendering, as well as requests for additional copies of the
Prospectus and this Letter, may be directed to First Union National Bank at the
address and telephone number indicated above.

GUIDELINES FOR DETERMINING THE PROPER IDENTIFICATION NUMBER TO GIVE THE PAYER.
Social Security numbers have nine digits separated by two hyphens: i.e.
000-00-0000. Employer Identification numbers have nine digits separated by only
one hyphen: i.e., 00-0000000. The table below will help determine the number to
give the Payer. All "section" references are to the Internal Revenue Code of
1986, as amended. "IRS" is the Internal Revenue Service.

PAYEES EXEMPT FROM BACKUP WITHHOLDING
The following is a list of payees exempt from backup withholding and for which
no information reporting is required. For interest and dividends, all listed
payees are exempt except item (9). For broker transactions, payees listed in (1)
through (13) and a person registered under the Investment Advisers Act of 1940
who regularly acts as a broker are exempt. Payments subject to reporting under
sections 6041 and 6041A are generally exempt from backup withholding only if
made to payees described in items (1) through (7), except that a corporation
that provides medical and health care services or bills and collects payments
for such services is not exempt from backup withholding or information
reporting. Only payees described in items (2) through (6) are exempt from backup
withholding for barter exchange transactions, patronage dividends, and payments
by certain fishing boat operators.

 (1) A corporation.
 (2) An organization exempt from tax under section 501(a), or an individual
     retirement plan ("IRA"), or a custodial account under section 403(b)(7), if
     the account satisfies the requirements of section 401(f)(2).
 (3) The United States or any of its agencies or instrumentalities.
 (4) A State, the District of Columbia, a possession of the United States, or
     any of their political subdivisions or instrumentalities.

     most recent publication of the American Society of Corporate Secretaries,
     Inc., Nominee List.
(15) A trust exempt from tax under section 664 or described in section 4947.

Certain payments, other than payments of interest, dividends, and patronage
dividends, that are not subject to information reporting are also not subject to
backup withholding. For details see sections 6041, 6041(A)(a), 6042, 6044, 6045,
6049, 6050A and 6050N, and the regulations under such sections.

PRIVACY ACT NOTICE. Section 6109 requires you to give your correct taxpayer
identification number to persons who must file information returns with the IRS
to report interest, dividends, and certain other income paid to you, mortgage
interest you paid, the acquisition or abandonment of secured property,
cancellation of debt, or contributions you made to an IRA. The IRS uses the
numbers for identification purposes and to help verify the accuracy of your tax
return. You must provide your taxpayer identification number whether or not you
are qualified to file a tax return. Payers must generally withhold 31% of
taxable interest, dividend, and certain other payments to a payee who does not
furnish a taxpayer identification number to a payer. Certain penalties may also
apply.

EXEMPT PAYEES DESCRIBED ABOVE MUST FILE FORM W-9 OR A SUBSTITUTE FORM W-9 TO
AVOID POSSIBLE ERRONEOUS BACKUP WITHHOLDING. FILE THIS FORM WITH THE PAYER,
FURNISH YOUR TAXPAYER IDENTIFICATION NUMBER, WRITE "EXEMPT" IN PART II OF THE
FORM, AND RETURN IT TO THE PAYER. IF THE PAYMENTS ARE OF INTEREST, DIVIDENDS, OR
PATRONAGE DIVIDENDS, ALSO SIGN AND DATE THE FORM.

PENALTIES
(1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER.  If you fail
to furnish your taxpayer identification number to a payer, you are subject to a
penalty of $50 for each such failure unless your failure is due to reasonable
cause and not to willful neglect.
(2) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING.  If you
make a false statement with no reasonable basis that results in no backup
withholding, you are subject to a $500 penalty.
(3) CRIMINAL PENALTY FOR FALSIFYING INFORMATION.  Wilfully falsifying
certifications or affirmations may subject you to criminal penalties including
fines and/or imprisonment.

                  FOR ADDITIONAL INFORMATION CONTACT YOUR TAX
                  CONSULTANT OR THE INTERNAL REVENUE SERVICE.
