I should have read this before going on an Alaskan cruise in Aug. We left from SEattle. When I saw SEA on my phone, I thought it somehow meant Seattle. After a few days, I found out it was international roaming. I had used my phone quite a bit. Fortunately I had told my cell provider a couple years ago to set my phone to not allow roaming. Because of that record, they removed all the charges. They had set the phone to no roaming, but it was automatically reversed about a month later. Saved me a couple hundred dollars.
