So I travelled to Europe last week. Knowing ahead of time I was heading there, I added the International Data Roaming Add-on and the International Voice Roaming Add-on. I also switched to a 1Gb plan with lots of data remaining within the cycle. After a few days there I finally decided to turn on my phone cellular service (iPhone 6S) to try calling home with FaceTime. My wife never answered her call so I hung off and turned off my cellular data. After stopping at a wifi area, I went on my self-serve menu to see that I just used slightly over 1 Mb of data and I am almost billed $6 for this quick phone call on FaceTime that never happened. Why is it that with international data and voice roaming activated I am billed data????
