I plan on visiting an AT&T store this week to see if I can get one of the data-only tablet sims for use with my captivate. Am I barking up the wrong tree here? These would be the type of sims used in things like the Galaxy Tab, etc. I could get by using VOIP if I could save a couple bucks a month. $25 for 2gb should do me just fine. I'm just not sure if they'd let me do it.

success! the kind folks at AT&T had no qualms with giving me the 2GB data plan for my captivate. they had to get a legit tablet serial number from the back room to activate the Sim, but all went very smoothly. only problem I see now is that the mobile internet service is horrifically slow. is it possible that i'm not configured to male use of the full 3g capacity of this thing? speedtests are coming in at about 30kbps.

edit: nevermind. 3g kicked in after a few minutes.

here's my configuration for getting the $25 2gb tablet plan working on my unlocked captivate.

I'm not sure, but I tend to doubt it. The guy at the AT&T store had to activate the Sim using a serial number he obtained from an unopened tablet box in the back room (very awesome of him to do so). Normally I think you can activate Sims directly from your device, but in this case it would read the model of your phone and fail to activate. I'm still half expecting to hear from AT&T in the near future telling me my device is ineligible for this type of service, but so far so good.

were you able to use it, or did AT&T cut you off?
