 EXHIBIT B 

Solvency Certificate 
 SOLVENCY
CERTIFICATE 
 [January 31], 2017 

This Solvency Certificate is being executed and delivered pursuant to Section 4.2(f) of that certain Credit Agreement dated as of
November 9, 2015, among T-Mobile USA, Inc., a Delaware corporation (the “Borrower”), the several banks and other financial institutions or entities from time to time parties thereto as lenders, and Deutsche Bank AG New York
Branch, as administrative agent and collateral agent (together with its successors and permitted assigns in such capacities, the “Administrative Agent”), as amended by that certain First Incremental Facility Amendment, pursuant to
which the First Amendment Incremental Term Loan Lenders have agreed to provide the First Amendment Incremental Term Loan Facility to the Borrower in the aggregate principal amount of $660,000,000 (the “Credit Agreement”; the terms
defined therein being used herein as therein defined). 
 I, [    ], a Responsible Officer of the Borrower, in such
capacity and not in an individual capacity, hereby certify as of the date hereof on behalf of Borrower as follows: 
  

	1.	The sum of the debt and liabilities (subordinated, contingent or otherwise) of the Borrower and its Subsidiaries, on a consolidated basis after giving effect to the incurrence of the First Amendment Incremental Term
Loans (the “Transaction”), does not exceed the fair value of the present assets of the Borrower and its Subsidiaries, on a consolidated basis after giving effect to the Transaction. 


 

	2.	The capital of the Borrower and its Subsidiaries, on a consolidated basis after giving effect to the Transaction, is not unreasonably small in relation to their business as conducted or contemplated to be conducted on
the date hereof. 

  

	3.	The present fair saleable value of the assets of the Borrower and its Subsidiaries, on a consolidated basis after giving effect to the Transaction, is greater than the total amount that will be required to pay the
probable liabilities (subordinated, contingent or otherwise), on a consolidated basis, of the Borrower and its Subsidiaries as they become absolute and matured. 

  

	4.	The Borrower and its Subsidiaries, on a consolidated basis after giving effect to the Transaction, have not incurred and do not intend to incur, or believe that they will incur, debts or other liabilities, including
current obligations, beyond their ability to pay such debts or other liabilities as they become due (whether at maturity or otherwise). 

  

	5.	For purposes of this Solvency Certificate, the amount of any contingent liability has been computed as the amount that, in light of all of the facts and circumstances existing as of the date hereof, represents the
amount that can reasonably be expected to become an actual or matured liability. 

  

	6.	In reaching the conclusions set forth in this Solvency Certificate, the undersigned has (i) reviewed the Credit Agreement and other Loan Documents referred to therein and such other documents deemed relevant and
(ii) made such other investigations and inquiries as the undersigned has deemed appropriate. The undersigned is familiar with the financial performance and prospects of the Borrower and its Subsidiaries. 








 EXHIBIT B 
  

	7.	The undersigned confirms and acknowledges that the Administrative Agent and the First Amendment Incremental Term Loan Lenders are relying on the truth and accuracy of this Solvency Certificate in connection with the
First Amendment Incremental Term Loans under the Credit Agreement.
