When travelling overseas I usually turn mobile data off on my phone to avoid high roaming charges, since smartphones seem to access the Internet continually in the background. If I use OIShare GPS logging, will still pick up my location so that I can transfer it to my photos? I tried it today, and it looked like it was mapping where I walked because a squiggly line appeared, but it doesn't show me any actual locations and after transfer to my camera I am not seeing the positions it which my photos were taken. Or perhaps this is for another reason? Any advice gratefully accepted.
