EXHIBIT 10.25.2



        SECOND AMENDMENT (this "Amendment"), dated as of September 17, 2001, to
the Credit Agreement dated as of August 28, 2000 (as amended, the "Credit
Agreement"), among Cricket Communications Holdings, Inc., Cricket
Communications, Inc., the Lenders party thereto and Nortel Networks Inc., as
Administrative Agent. Capitalized terms used herein and not defined herein shall
have the meanings assigned to such terms in the Credit Agreement.

        WHEREAS, the Credit Agreement provides that the aggregate principal
amount of all Indebtedness described in clauses (a), (b) and (c) of the
definition of "Eligible Secured Debt" contained therein may not exceed
$1,845,000,000; and

        WHEREAS, the aggregate total of loans and commitments under the Credit
Agreement, the Lucent Credit Agreement, and the Credit Agreement, dated as of
October 20, 2000 among Holdings, Borrower, the lenders party thereto (including
Ericsson Credit AB) and the Administrative Agent thereunder (the "Ericsson
Credit Agreement") equals $2,370,000 (i.e., $525,000,000 more than Borrower may
currently borrow as Eligible Secured Debt under such credit agreements); and

        WHEREAS, Borrower does not anticipate that it will be requesting, in the
near term, Borrowings under the Credit Agreement which would cause the sum of
the Loans made pursuant to the Credit Agreement to exceed $300,000,000 in
principal amount; and

        WHEREAS, Holdings, Borrower and the Required Lenders have discussed
amending the Credit Agreement to provide a limit on the available commitment of
Nortel Networks in relation to the aggregate principal amount of Loans held by
Nortel Networks at any time; and

        WHEREAS Holdings, Borrower and the Required Lenders have discussed
certain additional amendments to the Credit Agreement regarding Borrower's
capital expenditures and gross revenues;

        NOW, THEREFORE, for and in consideration of the mutual agreements
contained in this Amendment and other good and valuable consideration, the
sufficiency and receipt of which are hereby acknowledged, the parties hereto
hereby agree as follows:

        Section 1.    Amendments.

        (a) Section 1.01 of the Credit Agreement is hereby amended by inserting
the following definitions in their appropriate alphabetical positions:

                "Available Commitment" means, with respect to each Lender, its
        Commitment; provided that the "Available Commitment" of the Nortel
        Networks Lenders shall not at any time exceed the excess, if any, of (a)
        the sum of all outstanding Loans and Commitments on the Effective Date
        over (b) the sum of the aggregate principal amount of outstanding Nortel
        Networks Loans at such time plus $225,000,000. At any time that there is
        more than one Nortel Networks Lender with a Commitment and the
        "Available Commitments" of the Nortel Networks Lenders are limited as a
        result of the forgoing proviso, the aggregate "Available Commitments" of
        the Nortel Networks Lenders shall



        be allocated between the Nortel Networks Lenders pro rata in accordance
        with their respective Commitments unless otherwise agreed between such
        Nortel Networks Lenders (it being understood that any such allocation
        shall not result in a Nortel Networks Lender's Available Commitment
        exceeding its Commitment). For purposes of this definition, if a Lender
        that is not a Nortel Networks Lender has a Commitment that, when funded,
        would result in a Nortel Networks Loan, then such Lender shall be deemed
        to be a Nortel Networks Lender solely for purposes of determining the
        extent to which such Commitment is an Available Commitment.

                "Nortel Networks Loan" means any Loan that is held by any Nortel
        Networks Lender or that is Guaranteed by Nortel Networks or any
        Affiliate thereof or for which Nortel Networks or any Affiliate thereof
        is otherwise directly or indirectly liable, pursuant to a make-whole
        arrangement or otherwise.

        (b) Section 2.01 of the Credit Agreement is hereby deleted in its
entirety and replaced by the following:

                SECTION 2.01. Commitments. Subject to the terms and conditions
        set forth herein, each Lender with an Available Commitment agrees to
        make Loans to the Borrower at any time and from time to time during the
        Availability Period in an aggregate principal amount not exceeding its
        remaining Available Commitment at the time. Amounts repaid in respect of
        Loans may not be reborrowed.

        (c) The first sentence of Section 2.02(a) of the Credit Agreement is
hereby amended by inserting the word "Available" after the word "respective" and
before the word "Commitments". In addition, Section 2.02(a) is hereby amended by
inserting the following sentence at the end thereof: "Nothing in this Section
shall be construed to require any Lender to make a Loan pursuant to a Commitment
that is not an Available Commitment."

        (d) The first sentence of Section 2.10(a) of the Credit Agreement is
hereby amended by inserting the word "Available" after the words "on the daily
amount of the" and before the word "Commitment".

        (e) Article V of the Credit Agreement is hereby amended by inserting the
following additional Section at the end of such Article:

                SECTION 5.18. Additional Capital Contribution. After September
        11, 2001, Holdings shall receive from Parent, as an equity investment by
        Parent into Holdings, and Holdings shall contribute to Borrower, as an
        equity investment by Holdings into Borrower, $140,000,000 in cash on or
        before the third Business Day after Parent completes the sale of FCC
        licenses for 10MHZ of C-Block spectrum covering the Salt Lake City and
        Provo, Utah BTAs and receives the net proceeds therefrom.
        Notwithstanding the foregoing, at least $70,000,000 in cash of the sum
        referenced in the first sentence of this Section 5.18 shall be so
        received as an equity investment by Holdings from Parent, and shall be
        so contributed as an equity investment by Holdings into Borrower, on or
        before December 15, 2001 regardless of whether or not Parent has



                                       2


        completed by said date the sale of FCC licenses for 10MHZ of C-Block
        spectrum covering the Salt Lake City and Provo, Utah BTAs and has
        received the net proceeds therefrom.

        (f) Section 6.15 of the Credit Agreement is hereby amended to read in
its entirety as follows:

               SECTION 6.15. Capital Expenditures. The Borrower will not permit
