Today Howard Forums user The Sweeper discovered a new Tracfone Inc. owned site at net10data.com. The single page site titled "IMPORTANT NOTICE" announces that;
"Effective March 1, 2013 Unlimited data service is not available on the Unlimited plan for AT&T SIM cards. AT&T SIM cards on an Unlimited Plan will be capped at 1.5 GB of data per month. This will apply even if you buy and redeem an unlimited service card that does not contain this limitation on its face. This limitation does not apply to phones using our non-AT&T SIM cards."
The page also offers a free T-Mobile BYOD SIM to any current AT&T SIM user who wishes t0 switch. The page has some tips for managing data and estimates of of what you can do with 1.5 GB of data, including the supposedly forbidden activities of streaming 50 hours of music or 12 hours of video. Now that there's a hard cap, hopefully NET10 will update their ridiculous terms of service which prohibit not only streaming but also downloading games and the use of third part apps that connect to the internet!
The new NET10 page is not linked from NET10's main site or their net10sim.com BYOD sales site. I initially suspected that it might be fake but the Whois records at GoDaddy, where the domain is registered, confirm that net10data.com is indeed owned by Tracfone Wireless, Inc., NET10's parent. I suspect the site was prepared for an eventual announcement by NET10.
So what about Straight Talk AT&T SIMs? Are they effected by the 1.5 GB cap too? I suspect they are but we won't know until Straight Talk makes an announcement, or a secret Straight talk data website is discovered.
