Do mobile phone signal boosters really work?
If you mean the ones that stick on the back of the phone then no they do not work, they are just a coils of wire inside and do nothing to boost your signal. However you can get boosters that you plug in like a small radio relay station but your phone will need the antenna plug on the back of it and you need to have it connected all times for it to work, although not very well. Best advice is to put up with it for now then at end of your contract change providers.
