Ford SYNC: Mobile Data Charges Using AppLink
Standard data rates will apply when using AppLink. Ford is not responsible for any additional charges you may receive from your service provider, when your vehicle sends or receives data through the connected device. This includes any additional charges incurred when driving in areas where you’re roaming out of a home network.
From time to time some data needs to be sent from AppLink to a backend server (e.g. VIN, SYNC module number, anonymous usage statistics and debugging information). These updates may take place automatically, which might result in some minimal charges.
