Actually I am surprise that the signal is very strong and the quality of the call is the same as my samsung 2 phone.
I connect it the bluetooth of my car and it function as good.
It is nice to have a phone in the watch, since I don't have to worry about the phone and I have important message anywhere I go.
It feel like james bond to have secret message in the watch on vibration mode.
It is the second Time I order true light in the box and I receive my order very fast by Dhl.
I recommand this watch to the world. 5 Stars
