BigWalleye, here’s another solution for you.
I had the same issue at my hunting camp. Crappy to no cell phone data reception inside the trailer.
I bought one of these pay as you go mobile hotspots from StraightTalk. Basically it’s just a wireless internet router so I can connect my cell phone and tablet to the wireless signal from this device.
I can set it in the window of the trailer or outside in a waterproof plastic container. I plug it in to one of those device charging batteries to keep it powered up and it lasts all weekend and then some.
$9.99 for the hotspot, $25 gets me 2 GB of data (and 30 days in which to use it) which for me is enough to listen to Wild games and run internet devices if the kids are up and need to download a movie or two.
I only really need it for the 4 months I’m up there deer hunting, so it’s a more cost effective solution than adding a hotspot to my cell phone plan which you have to keep active all year. For $100, I get all the internet I neeed for the season.
The key is getting that hotspot outside where the metal walls don’t screw up the reception. Sometimes just putting it in the window works fine, but on some days even that isn’t good enough and I have to put it outside in the waterproof case to get a good signal.
Just another idea for you.
