Can I use navigation on my phone locally? Do I need a local SIM card ?

If you want to use Google navigation, you definitely need to use a local card. Orange is also okay.
Don't use Google Map with domestic card roaming, as it may result in delays or inability to connect to the server.
As long as the signal can be guaranteed. I use the WiFi rented in the domestic. Many times on the road, the signal dropped. Sometimes you have to stop and look for signals. If you find no signal, it is best not to turn off the navigation, it will run offline, but there will be no voice prompts. In addition, I think Apple's built-in map navigation is the most convenient to use, Google is second.
