You can protect your mobile data plan a little when using Medic52, by setting the app to only upload images, signatures and audio statements over Wifi only.
From the home screen, list of cases, hit the Settings Icon.
Hit the Cog icon to get to settings.
Flick the switch!
And you are done!
Now just make sure you are hooked up to your resort wifi, so when you hit the base or get in range, the data will upload as soon as you open the app.
