I have an LG Nexus 5. Unfortunately, when you first setup Android for the first time, data automatically turns on for the setup process. There is no way to bypass this until you skip through the setup process to turn off data.
My plan does not have data, so the 6mb that were used during the setup process was charged to my account.
Is there anyway to dispute this? It seems unfair from my perspective as I did not intend to use data, it the default when first setting up Android.
