Ladies and Gentlemen:

We have acted as special counsel to Sprint Communications, Inc., a Kansas corporation (the “Guarantor”), a wholly-owned subsidiary of Sprint Corporation, a Delaware corporation (the “Company”), in connection with the Company’s filing on February 11, 2015 of a Registration Statement on Form S-3 (as amended or supplemented, the “Registration Statement”) with the U.S. Securities and Exchange Commission (the “Commission”) pursuant to the Securities Act of 1933, as amended (the “Securities Act”), relating to, among other things, the registration of the Guarantor’s guarantees (the “Debt Guarantees”) of debt securities of the Company (the “Debt Securities”) to be authorized, issued and sold from time to time, on a delayed basis, by the Company in one or more series, with the same or various maturities, at par or at a discount, certain of which may be convertible into or exchangeable for Common Stock, in each case as contemplated by the Registration Statement to which this opinion has been filed as an exhibit. The Debt Securities and related Debt Guarantees may be issued from time to time pursuant to Rule 415 promulgated under the Securities Act.

In connection with this opinion, we have examined:

(D) a certificate from the Kansas Secretary of State indicating that the Guarantor is in good standing in Kansas as of February 9, 2015;
