I'm about to go to Europe (from US). I just read this on another forum after thinking I had everything straight in my head "just a reminder for anyone traveling internationally: If your phone ever registers on an international carrier network , even if you turn it off thereafter, and someone calls and leaves you a voicemail, whether or not the phone is on or not, you will still be charged for that person leaving you a voicemail. Go to http://wireless.att.com/international and read all the details before using your phone internationally, I highly recommend it." This seems to contradict this At&t page here that says "When your device is on: * Calls that you do not answer that are routed to the AT&T voicemail system will be charged as an international roaming incoming call to your device. * In addition, the foreign carrier's routing of that call to the AT&T voicemail system may generate an outgoing call charge from your device's location to the U.S. * These charges apply even if the caller disconnects from the voicemail system without leaving a message. If your device is turned off or in flight mode and the wireless network is off: * When someone tries to call you, the call will go directly to your personal voicemail greeting. * Since the network does not try to deliver the call to you in a foreign country, there are no international roaming charges. " So is the person on the other forum talking out of their ass??!!?? I was intending to mostly keep my phone in airplane mode apart from maybe the odd SMS message. My worry is if I ever switch airplane mode off then i'd start getting charges for voice mails even if my phone is off or in airplane mode. Anyone who's been abroad know? Mark.
