Using Location services abroad without roaming charges I have an offline maps application (maps.me) on my iPhone 5S GSM.

Can I use the location services function abroad without getting charges for roaming when Cellular data is turned off?

(Only data is turned off. The normal telephone network is active and online.)

Please see the screenshots below for my current configuration: 





If you need any further information, please ask in the comments.
As long you are using the Network provide they will charge you. Voice or Data or both.

Location service also works with GPS, Bluetooth (only short range) and WiFi.

As long you are in a free WiFi (and turn off voice and data) it is the best way to avoid any surprise charges.
