Why can't my Google Map be used at all without Wi-Fi, and I keep using Apple Map ?

Domestic cards won't work, use local cards for data.
Need to download offline maps in advance.
Check if Google Maps data is enabled.
With offline maps, GPS signal is all that is needed, provided that the offline maps are loaded first.
Are you using domestic card traffic?
Have you turned on the data for Google?
