Which generation of mobile phone service introduced digital networks with SMS and text messaging capabilities?

The introduction of digital networks with SMS (Short Message Service) and text messaging capabilities aligns with the second generation of mobile phone service, known as 2G. This technology marked a significant shift from the analog systems of the first generation, allowing for not only voice communication but also data services.

With 2G, networks began using digital encoding to improve the quality and efficiency of mobile communications. SMS, a popular feature that allows users to send text messages, was developed during this generation, enabling a new form of communication that was both quick and efficient. This shift also allowed for better integration of voice and data services, enhancing the overall user experience.

While the other generations—1G, 3G, and 4G—made significant advancements in mobile technology, 1G was primarily focused on analog voice communication. 3G introduced faster data speeds and multimedia capabilities, while 4G further enhanced speed and functionality, including mobile broadband services. However, it was 2G that first brought digital services and text messaging into the mobile communication landscape.
