THIS CONSULTING AGREEMENT (this “Agreement”), is entered into effective as of July 1, 2020 (the
“Effective Date”), by and between T-Mobile US, Inc. (the “Company”) and J. Braxton Carter (“Consultant”). 

WHEREAS, the Company wishes to secure the services of Consultant as a consultant of the Company upon the terms and subject to the conditions
set forth herein, and Consultant wishes to render such services to the Company upon the terms and subject to the conditions set forth herein. 

NOW, THEREFORE, in consideration of the mutual agreements set forth herein and for other good and valuable consideration, the receipt and
adequacy of which are hereby acknowledged, the parties hereto hereby agree as follows: 
 1. Term. Unless this Agreement and
the consulting relationship established hereby are earlier terminated as provided for herein, the term of this Agreement shall commence on the Effective Date and end on September 30, 2020 (the “Initial Consulting
Period”); provided, however, that the Company shall have the right (but not the obligation) to extend the term of this Agreement by an additional three (3) months through December 31, 2020 (the “Additional
Consulting Period”) by providing Consultant with written notice of such extension no later than September 1, 2020. The Initial Consulting Period and the Additional Consulting Period (if any) are collectively referred to herein as
the “Consulting Period.” 
 2. Services. During the Consulting Period, Consultant shall provide such
consulting services as may be reasonably requested by the Company (the “Services”). Consultant acknowledges and agrees that the Services shall be performed with the degree of skill, care and diligence expected of a
professional experienced in providing the same or similar services, personally and using his reasonable best efforts at all times to promote the business and interests of the Company. Consultant shall provide the Services to the Company at times and
locations mutually agreed to by Consultant and the Company (up to a maximum of ten (10) days per month; it being understood that any partial day of work shall count as a full day for purposes of the foregoing maximum). Consultant shall comply
with all applicable policies and procedures of the Company (including, without limitation, any technology use, confidentiality, background check and work authorization policies and procedures). 

3. Compensation. 

a. Fees. During the Consulting Period, as full and complete payment for Consultant’s provision of the Services, (i) the
Company shall pay Consultant a consulting fee (the “Consulting Fee”) equal to $210,000 per month (pro-rated for any partial month of service), and (ii) Consultant shall continue to
remain eligible for the Company’s mobile service discount program as in effect from time to time. The Consulting Fee shall be paid monthly in arrears, no later than the fifteenth (15th) day
of the calendar month following the month in which such Consulting Fee was earned. 
 b. Invoices. Consultant shall submit invoices
and/or reports of Consultant’s progress on assigned duties and projects to the Company as and when requested by the Company, which invoices shall describe in detail the Services provided and the time expended by Consultant on such Services each
month.

 4. Termination. This Agreement and the consulting relationship established
hereby shall terminate automatically upon the expiration of the Consulting Period. This Agreement and the consulting relationship established hereby may be terminated by the Company with or without Cause at any time and by Consultant for any reason
or no reason, provided that Consultant must provide at least thirty (30) days’ prior written notice to the Company prior to any such termination for convenience. For purposes of this Agreement, “Cause” means the
occurrence any one or more of the following: (i) Consultant’s gross neglect or willful material breach of Consultant’s Services hereunder, (ii) a final judicial adjudication that Consultant is guilty of any felony (other than a
law, rule or regulation relating to a traffic violation or other similar offense that has no material adverse effect on the Company or any of its affiliates), (iii) Consultant’s breach of the Confidentiality Agreement or the Covenants (each as
defined below), (iv) fraudulent conduct as determined by a court of competent jurisdiction in the course of Consultant’s Services hereunder or (v) the material breach by Consultant of any other obligation to the Company which continues
uncured for a period of thirty (30) days after notice thereof by the Company and which is demonstrably injurious to the Company or affiliate thereof. 

5. No Payments Upon Termination. Upon the termination of this Agreement and the consulting relationship established hereby for
any reason, all compensation payable to Consultant under this Agreement (including payments of the Consulting Fee) shall cease as of the applicable date of such termination, and (a) the Company shall pay to Consultant, following such
termination, a lump sum equal to any Consulting Fee earned or accrued and unpaid through the date of termination and (b) Consultant shall continue to remain eligible for the Company’s mobile service discount program as in effect from time
to time. In addition, in the event of the termination of the consulting relationship established hereby by the Company without Cause, the Company shall pay to Consultant the aggregate amount of the Consulting Fee that would have been payable over
the remainder of the Initial Consulting Period (or, if the date of termination occurs during the Additional Consulting Period, over the remainder of the Additional Consulting Period) had the consulting relationship not terminated, payable in a
single lump sum as soon as administratively practicable following the date of termination. Except as expressly provided in this Section 5, Consultant shall not be entitled to any further payments in connection with or following the termination
of this Agreement and the consulting relationship established hereby. 
 6. Acknowledgement. Consultant acknowledges and agrees
that he is subject to and bound by certain restrictive covenants set forth in the Restrictive Covenant Agreement (as defined in that certain Amended and Restated Employment Agreement between the Company and Consultant, dated December 20, 2017)
and that certain Letter Regarding Severance Benefits between the Company and Consultant, dated April 28, 2018 (collectively, the “Covenants”) and that the Covenants shall remain in full force and effect in accordance
with their respective terms. Consultant further acknowledges and agrees that the entrance into this Agreement by the Company and the payment to Consultant of the Consulting Fee is subject to and conditioned upon Consultant’s continued
compliance with the Covenants. 
 7. Confidentiality Agreement. Consultant acknowledges and agrees that, concurrently with the
execution of this Agreement, Consultant is entering into an agreement with the Company containing certain confidential information and invention assignment provisions (the “Confidentiality Agreement”), and that Consultant

 8. Independent Contractor. The Company and Consultant expressly agree that
Consultant is solely an independent contractor and neither Consultant nor any principal, employee or contractor of Consultant shall be construed to be an employee of the Company in any matter under any circumstances or for any purposes whatsoever.
Nothing in this Agreement shall establish an agency, partnership, joint venture or employee relationship between the Company and Consultant, and Consultant shall not represent himself as an employee or officer of the Company. The Company and
Consultant agree and acknowledge that neither party hereto renders legal, tax or accounting advice to the other party. Without limiting the generality of the foregoing, (i) the Company shall not pay, on the account of Consultant or any

b. Proprietary Information. Consultant hereby represents that (i) Consultant’s performance of Consultant’s duties under
this Agreement will not require Consultant to, and Consultant shall not, rely on in the performance of the Services or disclose to the Company or any other person or entity or induce the Company in any way to use or rely on any trade secret or other
confidential or proprietary information or material belonging to any other party; (ii) neither the services that Consultant provides nor the information or materials that Consultant develops for or discloses to the Company, shall be based in

 11. Limitation of Liability. To the maximum extent permitted by applicable law, in
no event shall the Company be liable to Consultant for any lost profits, lost business or consequential, incidental, special or indirect damages of any kind, whether arising in contract, tort or otherwise, and regardless of whether the Company has
been notified of the possibility of such damages. To the maximum extent permitted by law, the Company’s maximum aggregate liability for any damages claim relating to this Agreement shall not exceed the amounts paid under this Agreement by the
Company to Consultant preceding such claim. Each party hereto acknowledges that the foregoing limitations of liability are an essential term of this Agreement between the parties and that in their absence the economic terms of this Agreement would
be substantially different. 
 12. Dispute Resolution. Except for any claims arising out of, or relating to, the Covenants,
any controversy, claim or dispute arising out of or relating to this Agreement or Consultant’s consulting relationship with the Company or termination thereof, either during the Consulting Period or afterward, shall be resolved exclusively by
arbitration in King County, Washington, conducted in accordance with the then prevailing commercial arbitration rules of the American Arbitration Association (the “AAA”), with one arbitrator designated in accordance with
those rules. The parties agree to abide by all decisions and awards rendered in such proceedings. Such decisions and awards rendered by the arbitrator shall be final and conclusive and may be entered in any court having jurisdiction thereof as a
basis of judgment and of the issuance of execution for its collection. All such controversies, claims or disputes shall be settled in this manner in lieu of any action at law or equity; provided, however, that nothing in this paragraph shall be
construed as precluding either party from bringing an action for injunctive relief or other equitable relief. In any such dispute, the prevailing party shall be entitled to its or his attorneys’ fees and costs, in addition to any other relief
that may be awarded.

addressed to the addresses set forth on the signature page hereto or to such other address as any party may have furnished to the other in writing in accordance with this Agreement.

d. Amendment; Waiver. This Agreement may be amended, and the terms and conditions hereof may be waived, only in a writing signed by the
parties hereto. No failure to exercise or delay in exercising any right, remedy, power or privilege hereunder shall operate as a waiver thereof or preclude any other or further exercise of any other right, remedy power or privilege hereunder or by
law.

among the parties hereto concerning the subject matter hereof and supersedes any prior understandings and agreements, whether written or oral, with respect thereto. All previous and contemporaneous discussions, promises, representations and
