I was on business trip in Europe (German, Poland) last week. I
have Driod Razr MAXX which is global phone. It was working fine except one
thing. My wife has iPhone 4S (AT&T). When she sent messages to me I always
got message with just one word “null” regardless of real content. Here in US
everything is OK and I get normal SMS from her. But in roaming I get “null”
messages. She was getting messages from me normally on roaming. So it wasn't
working in one way only. Don't know who to blame. But looks like something
wrong with Verizon messaging on international roaming.
