Anyway to get a tiny bit more signal/reception?

Complete longshot, but figured it was maybe worth asking anyway... where I live atm is a joke for reception, I get one bar and it can sometimes take hours for a text to come through and rarely am I able to receive incoming calls - I was wondering if there anyway at all just to get a slight boost?

Complete longshot I know, but was just curious is there was something that worked for you guys :S

Cheers

 

Thanks GOP, I'm moving out soon (within a month or so) so was after something a little less pricey/permanent, but I'll consider it anyway, tyvm.
