Reach List for the Americas

Mblox enables businesses to deliver mobile services and content around the world while simplifying the commercial and technical complexities involved. Specializing in global operator connectivity and mobile billing, Mblox maintains connections to more than 800 mobile operators in over 200 countries through its carrier- grade network.

In the Americas, Mblox provides connectivity with the optimized gateways each operator reserves solely for application-to-person (A2P) message traffic. This document includes operators available for each type of program offered by Mblox and will be updated as coverage is added.

Types of Programs • Standard Rate. All messages on the program are billed to the consumer at their standard operator rates, or deducted from their message bundle if they have a data plan. Most major US operators charge the consumer for both mobile originated (MO) and mobile terminated (MT) messages. No premium charges are applied and there is no payout to the service provider. • Free To End User. All messages on the program (both MO and MT) are free of any charges to the consumer. The consumer does not pay standard message charges. There is no payout to the service provider. • Text (Txt). All messages on the program contain plain text only and do not provide the consumer with access to richer media. • Download (DL). The program provides the consumer with access to rich media content or mobile web/WAP sites. This is achieved by embedding links in SMS messages or sending binary WAP Push SMS messages, depending on the network operator capabilities. • MMS. The service provider may send rich media content to the consumer using MT MMS messages and MO MMS messages. The MMS messages themselves are sent as standard rate messages with a different set of carrier pass through fees. Please reference the Mblox Network Operator Fee list for carrier specific fees.
