I am planing to buy Samsung Galaxy phone for my hiking trips to use it solely as gps device. there will be no calls made from the phone and i do not need service. now looks like say Sprint locked phones are cheaper
than unlocked ones so i am wandering if i will be able to use the phone when it is locked to Sprint. again i just need to install gps app on it and run it, and need to be able to use wireless to access internet. is this possible with locked phone or do i need unlocked one for this?

thanks
