This is pretty good news. However, you would still be charged for roaming phone calls if you turn on your phone and someone calls you. This is frustrating especially when you refuse the call because it gets sent to voicemail and you are charged for a call from Europe to the US for the duration of your caller listening to the welcome message and leaving a message.
I guess I can use this on my data-only device. Though in most cases I buy local SIM card, but if going through many countries, this avoids having to get a SIM card in each country.
