The portable version of cell phone amplifier is very useful and is suitable and very handy for travelers to use, especially those who travel a lot and often go to remote areas with almost void signal reception. But these boosters are not usable where the service is not available. It can just boost the weaker signals. It can’t create signals on its own. It is very handy as it looks good also when used in car. However there is also some integration like AC adapter available to make the portable booster used in hotels also. You have to place the antenna on the roof of your car or on the windshield with the help of suction cups or the magnetic base of antenna.
