Hi
Is there such a thing as a 'universal' signal booster that fits into your car, works for all mobile phone networks?
If so, please can someone recommend one :^)
e.g.
Does this sort of thing actually work?
[On amazon search for: "IPHONE SAT NAV GPS SIGNAL BOOSTER ANTENNA AERIAL"]
There reviews talk a lot about SatNavs being helped, but what about a mobile phone's voice channel?
Thanx
