I am a relatively recent user of a smart phone, so I don't know if you will get some kind of charge for call/text attempts even if in airplane mode.
Uncle Vanya beat me to it!
Airplane mode blocks all radio signals to avoid interference to the airplane electronics. So your phone can not send nor receive : hence no calls, no data, no sms/text, so it can not even attempt to do something on the mobile network that would generate charges....
There is one exception possible in airplane mode : Bluetooth or wifi can be switched on manually so you can connect headset and listen music in airplane, at least, provided the music is stored on your phone and not online in a streaming service of course.... Bluetooth is not charged, it is local, not connected to your network provider. WiFi might be used to connect to the ?mostly paying? WiFi service in airplane... most airlines ask to stop WiFi and Bluetooth during take-off and landing but allow during flight.
You can indeed use airplane mode abroad to block paying services, but still use you wifi ( like on hotel wifi) or Bluetooth and gps to your camera...
Without data connection, the phone gps might take several minutes to find new location, as most phones use assisted gps : the first location is calculated with external help , hence data connection. Smaller changes of location are quicker and rely less on external help. It will work without assistance, but the gps chip needs much more time to interprete gps signals. So your first picture after image sync might take time.
Most phones allow data roaming to be blocked, to avoid roaming data charges. But still use voice or txt sms messages. In android , settings , search for ’roaming’.
Another trick:
Use callforward unconditional to your voicemail service. Effect is similar to switching phone off for incoming(receiving) calls, they will go immediately to voice mail. Your voice mail might send txt sms to notify you who tried to call you. But txt costs are bearable... . You can still make calls or send/recieve sms txt with this setting.
Some networks allow to activate this from their website (your account site) or use:
Dial **21*1+PhoneNumber# and green button to send, this turns on unconditional forwarding (CFU) to a number (use voice mail number, sometimes called direct deposit number).
##21# Turn off unconditional forwarding.
Ideally you do and test this before you leave, even the activation with **21*1 needs to be paid for. Note that phone numbers should be in full using +CC (country code) full number.
One can also use the do not disturb or night function of the phone to avoid incoming calls/ ringing.

But if you mount the gps to your camera turn it on and wait until the camera indicates the gps is tracking take a photo and review it you should see the icon on the left hand middle of the screen indicating gps data recorded...
If you changed continents, the gps unit might need a few minutes to find out it's new location..? Maybe the camera waiits for this.
