If you get any service at all its likey you can add a yagi antenna and
have 5 bars perfect service. you connect your cell phone with a small
adapter to a 20 ffot cable on the antenna that gets mounted outside,

I have friends in a bad spot with alunmimum siding. previously they had

with the antenna under 50 bucks they have 5 bars whioch is the max and
have flawless service with that wire connection.
