Just get an app for your phone. I do have a Garmin Inreach because its got text anywhere and the SOS button to bring on Search and Rescue in an emergency. It is a good gps but I don't use it I keep it off and only use for texts to check in. I use my phone with IHunter and it works perfectly without cell service which there just about never is any where I hunt. Way way better image and all the features and tracking that a gps with a chitty screen has.
How does that work without cell service?
Because when your using a GPS app on your phone, there is no need for cell service. It uses the GPS antenna that is built into just about every smart phone and picks up signals from the GPS satellites overhead.
