I've been a mostly happy Cingular customer for about 3 years. I like my GSM phones, I even have a pay-per-call SIM for when I travel outside the US. I was recently on a cruise from Puerto Rico, which from a cellular point of view is in the US. I was surprised to see folks talking on their cell phones, as we were a couple of miles from shore. I turned mine on and it said "Cingular" with 5 bars. That's pretty cool, apparently they have some deal with the cruise ship company to put a cell relay on the ship. Over the next week I even made a couple of calls. Since I'd not known this feature was present, I didn't tell anybody about it. My phone spent most of it's time in the stateroom safe. Imagine my surprise to get a $300 phone bill. There are two things going on. First, the network that displays "Cingular" on my handset is not Cingular, but rather Cingular At Sea. This is a totally different network, and alas my phone hasn't got a big enough display. Thus all the calls I made were "International Roaming" at a cost of $3 a minute. Second, anyone who called my phone made the same sort of call, even though they got voice mail. I you left me a 5 minute voice message, that cost $15. When I spoke to Cingular Customer Service, they said four things that made me want a new cellular carrier: 1) I should have checked rates on their web site before I left. How was I to know that this was even an option? 2) I should not associate "Cingular" on the display with being on the Cingular network. They were unable to tell me any process for confirming I was on the Cingular network. 3) There is not any way to prevent my account from international roaming. I must know the boundaries of their network and never allow my phone to leave it. 4) They thought it could have been much worse. The rep told me that sometimes girls spent $1000 talking to their boyfriends while on a cruise. I explained that $300 was six-months of charges for me and not a minor fee. Frankly, I'm not that attached to my phone number. I'm thinking about switching to another GSM service provider. With nationwide calling plans, how can I find a carrier that doesn't support this international roaming scam? In this case, anyone but Cingular would do, but I'd like to encourage a company that thinks about the customer implications of it's service. Any suggestions?? Thanx in advance.
