Ranking	The notes will be our unsecured and unsubordinated obligations and will rank equally in right
	of payment with all of our other unsecured and unsubordinated debt. The notes will be
	effectively subordinated to all of our existing and future secured obligations and to all
	existing and future liabilities of our subsidiaries. Some of our outstanding debt securities that
	were issued in the Mexican and international markets are guaranteed by our subsidiary
	Radiomóvil Dipsa, S.A. de C.V. ("Telcel"). Accordingly, the holders of those outstanding
	debt securities will have priority over the holders of the notes with respect to claims to the
	assets of Telcel. In addition, some securities we have issued in the Mexican and international
	markets provide for a covenant and events of default relating to Telcel (specifically, relating
	to our continued control of Telcel and to defaults or insolvency events involving Telcel) that
	are not included in the notes offered hereby. The notes do not restrict our ability or the ability
	of our subsidiaries to incur additional indebtedness in the future.
	As of March 31, 2019, we had, on an unconsolidated basis (parent company only), unsecured
	and unsubordinated indebtedness of approximately Ps.517.8 billion (U.S.$26.8 billion)
	excluding guarantees of our subsidiaries' indebtedness and lease debt recognized pursuant to
	International Financial Reporting Standard 16, Leases ("IFRS 16"). As of March 31, 2019,
	our subsidiaries had indebtedness (excluding guarantees of indebtedness of us and our other
	subsidiaries and lease debt recognized pursuant to IFRS 16) of approximately Ps.136.6 billion
	(U.S.$7.1 billion).
Use of Proceeds	We intend to use the net proceeds from the sale of the notes for the repayment of outstanding
	indebtedness. See "Use of Proceeds" in this prospectus supplement.
Further Issuances	We may, from time to time without the consent of holders of the notes, issue additional notes
	on the same terms and conditions as the notes (except for issue date, issue price and the date
	from which interest will accrue and, if applicable, the date on which interest will first be
	paid), which additional notes will increase the aggregate principal amount of, and will be
	consolidated and form a single series with, the notes.
Payment of Additional Interest	If you are not a resident of Mexico for tax purposes, payments of interest on the notes to you
	will generally be subject to Mexican withholding tax at a rate of 4.9% or, in certain
	circumstances, 10%. See "Taxation-Mexican Tax Considerations" in the accompanying
	prospectus. We will pay additional interest in respect of those payments of interest so that the
	amount you receive after Mexican withholding tax is paid equals the amount that you would
	have received if no such Mexican withholding tax had been applicable, subject to some
	exceptions as described under "Description of Notes-Payment of Additional Interest" in this
	prospectus
