The founder and CMD of Celkon group is Y. Guru. Initially its mobiles and tablet PCs were assembled in Taiwan and China.[2] Celkon[3] started its assembly line in Medchal, Hyderabad with a capacity of 200,000 mobile phones and later set up two more units – one in Tirupati, Andhra Pradesh and other in Hyderabad, Telangana.[4][5] However, the company ended up for lack of innovation and funding and now does not produce dual-sim and single sim, VoLTE and LTE smartphones, feature phones and Android and Windows tablets.
