Eric Warmenhoven: Cingular sucks.
Lisa has been thinking for a short while that she’d like to get a Motorola RAZR phone. We were AT&T Wireless customers, which now makes us a weird type of Cingular customer where we not only have our AT&T plan, but also special AT&T customer service representatives (which I’ll get to in a bit). So we went into our local Cingular store and she asked about getting the shiny new black RAZR, and they said that it wouldn’t be a problem, they’d just need to upgrade our service, and since we’re on the same plan and the service is changing, I’d need to upgrade my phone as well.
AT&T Wireless has a email-to-SMS gateway and gives every phone its own email address, yournumber@mmode.com. Since AT&TWS only charges if you send a message but not if you receive a message, I use it all the time (mostly for stock quotes but also for various other things). So in an average month I probably receive 30-50 emails on my phone, as well as the occasional spam, all of them free.
Cingular has the same service, yournumber@cingularme.com. But unlike AT&TWS, Cingular charges you both for sending and receiving messages. (”Text, Instant, and Multimedia messages are charged when sent or received, whether read or unread, solicited or unsolicited.”) So my 30-50 messages a month are going to cost me $3.00-$5.00 a month. Of course, I could always get a package, which will limit those 50 messages to just $3.00. Or I could get a $20 package that lets me receive 2500 messages. That’s not the point.
The point is that once that limit is hit, it goes back to $0.10 per message, regardless of the plan. That means that some evil person can send you thousands of messages and you could end up owing hundreds of dollars. The only way to prevent that is to call Cingular and turn off the E-Mail Messaging feature from your service. (You can use the Message Center to “Create block and allow lists to limit e-mail messages received” and “Control what times of day your phone can receive e-mail messages.” Also it looks like you can block email containing some spam attributes. But none of those things guarantee that you’re not going to get a bunch of junk.)
I tried calling Cingular to confirm this, and when I entered my phone number, it redirected me to AT&TWS customer service, who confirmed that AT&TWS does not charge for receiving text messages, and confirmed that Cingular does charge for receiving messages, but did not have an answer for how Cingular deals with spam. In fact, they didn’t seem to have a lot of information about the Cingular service at all, other than how to “upgrade” my account to a Cingular account. I had to call Cingular sales, who also didn’t know the answer to how to prevent abuse; but they were able to transfer me to Cingular customer service, who confirmed that yes, I really do have the potential to get screwed if I don’t turn off E-Mail Messaging.
