Introduction
The Celkon A60, launched and released in August 2013, represents a snapshot of early smartphone technology that catered primarily to budget-conscious consumers looking for basic functionality. Although it is now discontinued, the A60 serves as an interesting case study in the evolution of mobile devices from a bygone era. Built to support dual SIM cards with basic connectivity options of the time, the A60 was ideal for users who needed separate phone numbers or who traveled frequently.
