After inquiring about this form my colleague I have opted to get this one which is really bad to choose. As I trust the maker of huawei but when used for more than an hour or two it will get over heated and will not give the best signal even if I am under the tower, just kidding.
It was weak in taking the signal and some times it will work fine with normal speed but some times it never works that too, it will get heated and more pathetic one to feel the use. I am not really satisfied as this was not useful for me to get the work done for which purpose I have bought and it was really a makeover of the speed which is not really agreat one to know. Better improve the speed and connectivity.
