Are signal boosters helpful to increase cell phone reception?

Signal Boosters are just a way of making a quick buck, however signal quality depends solely on the instruments and cell towers put up by the service providers, it so happens that some providers ride on networks of other service providers and so the quality in signal strength is weak in fact there are network issues depending on the type of coverage like indoor coverage and out door coverage just check with your provider what type of coverage they have in your area and also ask them for advice as to which handset gives you better quality network because if they are using the 2.5 g instrument in your area it will be useless if you have a 3 g network enabled phone, what is recommended is to use the 850 mghz or the 900 mghz handset instead, remember using these signal boosters could create problems like virus and even more dangerous could also hinder any other computerized systems especially if you are a frequent flyer or work in a area which could be dangerous to use a cell phone in certain industries.
