Signal in my apartment varies from 1 bar to no signal. Sadly, from my apartment is where I want to do most of my talking.

I've been looking into signal boosters and I've come across a few different options:
1). The easiest/cheapest

2). or

I personally like option 2; however, the item only offers signal boosting for Telus. Does anyone have experience with either of these devices? Will a signal booster for Telus work for Koodo? Will either of these devices work even a little bit (not necessarily the ebay ones I've listed, but a device similar to them)?
Oh no! Sorry.
