I have a few question to ask. 1) How was it work? 2) What is the price for 1 unit? 3) My house area(within the building) has a very weak signal.. Im using an iphone 5 and am using Celcom. Sometimes there is 'No Service' most of the times its 'E' and very rarely it is '3G'. I want to ask where this product will help with my problem and will this product help to get me even a 4G tho Im not sure if my area has 4G in general. Will more antenna determine a more stronger and stable internet connection? Thank you
