Which of the following statements is NOT true?

The statement regarding 1G cellular networks is indeed the one that is not true. First-generation (1G) cellular networks were primarily analog systems that focused on voice communication only. They did not support data services due to their technological limitations, which means that the ability to transmit data, such as texts or internet access, was not available at this stage.

In contrast, the second generation (2G) networks introduced digital transmission and allowed for voice and messaging services. The advancements continued with 3G and 4G networks, which support both voice and data services, increasing bandwidth and enabling a wide array of applications. Finally, 5G networks are designed to facilitate an even more extensive range of services, including support for the Internet of Things (IoT) and other data-heavy applications, making them highly suitable for modern connectivity needs.
