Exhibit 4.1

INTERCOMPANY REVOLVING CREDIT AGREEMENT

             This INTERCOMPANY REVOLVING CREDIT AGREEMENT is dated as of November 9, 2005 and is among UNITED STATES CELLULAR CORPORATION, a Delaware corporation (referred to herein as the “Borrower” or as the “Company”) and TELEPHONE AND DATA SYSTEMS, INC., a Delaware corporation (referred to herein as the “Lender” or as “TDS”).

             The Company has requested that TDS extend, and TDS has agreed to so extend, a revolving credit facility to the Company as described herein.

             Accordingly, solely on the terms and conditions set forth herein, the parties hereto hereby agree as follows:

SECTION 1. DEFINED TERMS.

        Certain capitalized terms used in this Agreement are defined in Schedule I; references to a “Section” or a “Schedule” are, unless otherwise specified, references to a Section of this Agreement or a Schedule attached to this Agreement.

SECTION 2. THE REVOLVING CREDIT FACILITY.

        Section 2.1. Commitment to Lend. Subject to the terms and conditions set forth in this Agreement, Lender agrees to lend to the Borrower and the Borrower may borrow, repay, and reborrow from time to time between the date of this Agreement and the Maturity Date, upon notice by the Borrower to the Lender given in accordance with Section 2.2, such sums as may be requested by the Borrower up to a maximum aggregate principal amount outstanding (after giving effect to all Loans then being requested) at any one time equal to the Commitment Amount; provided that the sum of the aggregate principal amount of all of the Loans at any time outstanding (after giving effect to all Loans then being requested) shall not exceed $105,000,000. Each request for a Loan shall constitute a representation by the Borrower that the conditions set forth in Section 4.1, in the case of the initial Loans made hereunder, and Section 4.2, in the case of all Loans, have been satisfied on the date of such request. Each Loan shall be denominated in U.S. Dollars.

        Section 2.2. Request for Borrowing. Whenever the Borrower desires to obtain a Loan hereunder or to convert an outstanding Loan into a Loan of another type provided for in this Agreement, the Borrower shall give to the Lender written notice in the form of Exhibit A hereto (or telephonic notice confirmed in a writing in the form of Exhibit A hereto), which written notice must be received by the Lender no later than (i) noon, Chicago time, on the day on which the requested Loan is to be made as, or converted to, a Base Rate Loan, and (ii) noon, Chicago time, on the date two (2) Business Days before the day on which the requested Loan is to be made as, or converted to, a Eurodollar Rate Loan. Each such notice (a “Loan Request”) shall specify the type of Loan (i.e., Base Rate Loan or Eurodollar Rate Loan), the Drawdown Date, or (as the case may be) the date of conversion, and principal amount of each Loan or the principal portion thereof to be converted, the interest rate option to be applicable thereto, and the duration

of the applicable Interest Period, if any (subject, in any case, to the provisions of the definition of the term “Interest Period”), and shall be substantially in the form of Exhibit A; provided, however, that when any Default or Event of Default is continuing, no Base Rate Loan may be converted into a Eurodollar Rate Loan. Each Loan Request shall be irrevocable and binding on the Borrower, and shall obligate the Borrower to accept the Loan of the type requested from the Lender on the proposed Drawdown Date or (as the case may be) to convert the Loan or a portion thereof as requested. Each Loan Request shall be in a minimum amount of $3,000,000 or an integral multiple of $250,000 in excess thereof.

        Section 2.3. Facility Fee, Utilization Fee.  

             (i)           The Borrower agrees to pay to the Lender a facility fee (the “Facility Fee”) calculated daily on the Commitment Amount in effect on such date at the per annum rate equal to that amount set forth on Schedule II in the row headed “Facility Fee” beneath the column for the Debt Rating in effect for such date. The accrued and unpaid amount of the Facility Fee shall be due and payable in arrears on the Maturity Date.

             (ii)          The Borrower agrees to pay to the Lender a utilization fee (the “Utilization Fee”) calculated daily on the principal amount of Loans outstanding on each day (the “Utilization Amount”) at the per annum rate equal to one tenth of one percent (0.10%) for each day on which the Utilization Amount exceeds $52,500,000. The accrued and unpaid amount of such Utilization Fee shall be due and payable in arrears on the Maturity Date.

        Section 2.4. Reduction in Commitment Amount. The Borrower shall have the right at any time and from time to time upon five (5) Business Days’ prior written notice to the Lender to reduce by $5,000,000 or an integral multiple of $1,000,000 in excess thereof, or terminate entirely the unborrowed portion of, the Commitment Amount, whereupon the Commitment of the Lender shall be reduced by the amount specified in such notice or, as the case may be, terminated. No reduction of the Commitment Amount may be reinstated. Notwithstanding the foregoing, upon the effective date of any such termination, the Borrower shall pay to the Lender the full amount of any Facility Fee then accrued and unpaid with respect to the portion of the Commitment Amount so reduced.

        Section 2.5. Note.  The Loans shall be evidenced by a promissory note of the Borrower in substantially the form of Exhibit B hereto (the “Note”), dated the date hereof, completed with appropriate insertions and payable to the order of the Lender in a principal amount equal to the Lender’s Commitment. The Borrower irrevocably authorizes the Lender to make or cause to be made, at or about the time of receipt of any payment of principal on the Note, an appropriate notation reflecting such payment on the note record (the “Note Record”) attached to the Note. The outstanding amount of the Loans set forth on such Note Record shall be prima facie evidence of the principal amount thereof owing and unpaid to the Lender, but the failure to record, or any error in so recording, any such amount on such Note Record shall not limit or otherwise affect the obligations of the Borrower hereunder or under the Note to make payments of the principal of or interest on the Note when due.

        Section 2.6. Optional Repayments of Loans.  The Borrower shall have the right, at its election, to repay the outstanding amount of any Loans, as a whole or in part, at any time

2

without penalty or premium; provided that in the case of any full or partial prepayment of the outstanding amount of any Eurodollar Rate Loans prior to the end of the Interest Period applicable thereto, the Borrower shall be obligated to reimburse the Lenders in respect thereof pursuant to Section 2.8. The Borrower shall give the Lender, no later than noon (Chicago time), at least two (2) Business Days’ prior notice of any proposed repayment of the Loans specifying the proposed date of repayment and the principal amount to be paid, which notice, if not in writing, shall be promptly confirmed in writing. Each such partial payment of Loans shall be in a minimum amount of $5,000,000 or an integral multiple of $1,000,000 in excess thereof. Each repayment pursuant to this clause shall be accompanied by the payment of accrued interest on the principal repaid to the date of payment.

        Section 2.7. Interest on Loans; Payments of Interest; Interest Period Options.  

             (i)           Except as otherwise provided by Section 2.10, each Base Rate Loan shall bear interest on the outstanding principal amount thereof at a rate per annum equal to the Base Rate in effect from time to time, which rate shall change contemporaneously with any change in the Base Rate.

             (ii)          Except as otherwise provided by Section 2.10, each Eurodollar Rate Loan shall bear interest on the outstanding principal amount thereof, for each Interest Period applicable thereto, at a rate per annum equal to the Eurodollar Rate determined for such Interest Period, plus the applicable Margin Percentage as in effect on the first day of such Interest Period.

             (iii)         The Borrower absolutely and unconditionally promises to pay all interest accrued on each Loan in arrears on each Interest Payment Date with respect thereto.

             (iv)          Upon written notice (a “Continuation Request”) given to the Lender in the form of Exhibit A hereto no later than noon (Chicago time) at least two (2) Business Days prior to the expiration of any Interest Period applicable to any Eurodollar Rate Loan, the Borrower may elect to continue such Eurodollar Rate Loan upon the expiration of the then applicable Interest Period for another Interest Period of the duration specified in such notice; provided, however, that no Eurodollar Rate Loan may be continued as a Eurodollar Rate Loan when any Default or Event of Default is continuing, and on the last day of the then current Interest Period with respect thereto each Eurodollar Rate Loan shall convert to a Base Rate Loan; and provided further, that the Eurodollar Rate Loans to which a particular Interest Period applies shall be in an aggregate principal amount of $3,000,000 or an integral multiple of $250,000 in excess thereof.

        Section  2.8. Indemnity. The Borrower agrees to indemnify the Lender and to hold the Lender harmless from any loss or expense that the Lender may sustain or incur as a consequence of (i) a default by the Borrower in payment of the principal amount of or interest on any Loans, including any such loss or expense arising from interest or fees payable by the Lender to lenders of funds obtained by it in order to maintain its Loans, (ii) default by the Borrower in making a borrowing after the Borrower has given (or is deemed to have given) a Loan Request or a Continuation Request in accordance with Section 2.2 or clause (iv) of Section 2.7, as applicable, other than as a result of a default by the Lender, (iii) the making of any payment of a Loan on a day that is not the last day of the applicable Interest Period

3

with respect thereto, including interest or fees payable by the Lender to lenders of funds obtained by it in order to maintain any such Loan or (iv) default by the Borrower in making any repayment of a Loan after the Borrower has given a notice in accordance with Section 2.6. This covenant shall survive the termination of this Agreement and payment in full of the amounts due hereunder.

        Section 2.9. Calculation of Interest and Fees. All computations of interest on Eurodollar Rate Loans and the Facility Fee shall be based on a 360 day year and paid for the actual number of days elapsed. All computations of interest on Base Rate Loans shall be based on a 365/366 day year and paid for the actual number of days elapsed. Except as otherwise specifically provided herein, whenever a payment hereunder or under the Note becomes due on a day that is not a Business Day, the due date for such payment shall be extended to the next succeeding Business Day, and interest shall accrue during such extension. The outstanding principal amount of the Loans as reflected on the Note Record from time to time shall be considered conclusive and binding (absent manifest mathematical error) on the Borrower unless, within seven (7) Business Days after receipt of any notice by the Lender of such outstanding amount, the Borrower shall notify the Lender to the contrary.

        Section 2.10. Interest on Overdue Amounts. Overdue principal of, and (to the extent permitted by applicable law) overdue interest on, the Loans and all other overdue amounts payable hereunder or under the Note shall bear interest compounded daily and payable on demand by the Lender at a rate per annum which is two percent (2%) above the per annum interest rate otherwise applicable to Base Rate Loans or (in the case of overdue principal of Eurodollar Rate Loans) applicable to Eurodollar Rate Loans, until such overdue amount shall be paid in full (after as well as before judgment).
