First of all the tab comes with a with a single sim, whereas its the age of dual sims now. Second is the touch. It's a faulty one. I used it for a month only and it just lost iys life after that. It was not responding to touches. The sound quality is not too clear.
There are noise in between the sounds. Extremely poor quality phone. When tried to solve out these issue due to lack of service centre I couldn't. Battery is also not upto that level to support good backup. Just don't buy this phone. You will suffer!
