On a flight from Hong Kong to Dubai in a 747 (about 2 years ago) I forgot to turn the phone off. On landing in Dubai I pulled the phone out and had a SMS message welcoming me to Bombay! We must have been up at about FL310'ish and passed within visual range of Bombay.
It may be unusual to get reception but I certainly had it that night.
