Devices fitting this description are smartphones utilizing the Android operating system, available for purchase at a low cost, and not restricted to any specific cellular network provider. These units typically offer basic functionality, serving as an entry point into smartphone technology or as a temporary solution. An example would be a device offering calling, texting, and limited internet access via Wi-Fi.
The availability of very low-cost, unrestricted mobile devices provides accessibility to communication and information for individuals with limited financial resources. Historically, such devices were largely unavailable, creating a digital divide. The rise of budget-conscious manufacturers and open-source operating systems has enabled broader access, facilitating participation in the modern digital society and enabling opportunities for education and social interaction.
