In the fast-paced world of telecommunications, latency reduction is crucial for the efficient delivery of SMS messages. Latency refers to the delay between sending and receiving a message. High latency can be detrimental, especially for time-sensitive communications such as two-factor authentication (2FA), transaction alerts, and emergency notifications. This article explores various techniques to reduce latency in SMS routing, providing a comprehensive guide to optimizing message delivery speed.

Understanding Latency in SMS Routing

What is Latency?

Latency in SMS routing is the time it takes for a message to travel from the sender to the recipient. It involves several stages, including message creation, transmission through the network, and final delivery to the recipient's device.

Causes of Latency

Several factors contribute to latency in SMS routing:
