For SMS and MMS messages delivered to destinations other than the United States, Puerto Rico, and Canada, Messaging Credit consumption rates vary substantially by destination and are typically several multiples of U.S. domestic rates.

7.4. Messaging charges accrued during a calendar month are invoiced in arrears in accordance with Section 8.3 of the SSA. Because consumption data is finalized after the close of the calendar month in which it accrues, Provider may invoice messaging charges separately from, and later than, the Fees set forth in Exhibit A. The Messaging Credits Prepayment operates as a prepaid balance of platform usage and is governed by Section 2.10 of the SSA.
