A direct connection is a valid and authenticated connection to the SMSC of a mobile network operator. At Sinch, we work directly with mobile operators to negotiate commercial contracts and to connect directly to their network.
This route is a direct connection to an operator or when the operator the SMS is designated for is located in the same country as the operator you are routing to (for example, usage of T-Mobile UK to deliver an SMS to Vodafone UK). This is often the most expensive, but the most reliable connection. Despite offering good service quality, Direct Routing does not always include standard features such as TPOA, Binary, and UDH.
