I purchased this because I heard a lot more positive reviews so I just bought this but after using this I found this service provider is not good. There is so much signal problems, the call drop regularly increased with the time.
Many times calls disconnected due to signal attenuation. Signal strength is continuously stays low. I complained this with the store they replaced my sim and charged twenty five bucks but still I am dealing with the same problem. I choose this as Airtel denied its service in the area I live. Data speed is not good enough and not even constant at slow speed. The add on of speedtest will work good, it will help users to check the data speed.
