Hi @Hls30104
Welcome to the Community
How is the signal outside the cabin? If its good outside the cabin, the booster would help indoor connectivity.
Cellphone signal boosters take the wireless signal and amplify the signal in the desired area. The catch is cellphone signal boosters don't always solve the entire issue.
If you are in a poor coverage area, then the booster would be amplifying a "weak signal" it may make things better but wouldn't solve the entire issue.
Also what device are you using? Have you completed any troubleshooting or submitted any reports to the network team?
Click here for a booster that was recommended to me from the network team.
Hope this helps
