It is allegedly only for San Francisco. It was showing me an option for this plan (family version) for $89.99 per month. I elected to change my plan from the one we have now to this unlimited plan and it went through everything, then gave me a "please wait" which at the end of it said "please call 1-877.. because we are unable to process your change request blah blah". So I called and was told that the only change the CSR could make to save me money would be to move me to a plan with less minutes and that it was an error that has been fixed "sorry"
I tried the "I'll change to a $9 per month plan and switch to AT&T" and that got me nothing but a "well I can request a cancellation for your plan if you like". *shrug* Congrats to anyone who got this! (outside of San Fran of course).
