So, here's the deal. I have an ATT ipad 3, with LTE. I also have two ipad data accounts. One is unlimited LTE, (as shown on my account settings page) the other is 2GB/$25 LTE, also from the settings page. I use the 2GB sometimes in an older ipad as navigation, but don't use it much and was going to cancel it, until.... January 26th... The day AFTER AT&T started buying 700mhz B spectrum from Verizon. coincidence? LTE stopped working on my iPad 3. Seemed weird, since it worked fine on my iPhone5. Waited several days, thought maybe an outage. Nope. Finally today I started searching online. And also, popped my 2GB sim into the ipad 3. My 2GB METERED sim, and.... immediately, LTE shows up. Swapped back and forth several times to confirm. Every time. unlimited sim gets no LTE, 2GB sim does. and full bars also. I'm in a fairly good coverage area with ul/dl generally over 10Mbps, and I've hit 20 before. My question.... Who with an AT&T unlimited iPad sim is experiencing this also? Is it possible that AT&T has disabled LTE on ONLY it's unlimited iPad sims? Could that be because FCC rules force providers who use certain spectrum to allow sims that operate in that spectrum to be unrestricted from "device switching"? Is the spectrum that those rules apply to coincidentally the very same spectrum that AT&T purchased from Verizon for $1.9 billion, ONE DAY before my LTE got shut off? Is AT&T disabling LTE on unlimited iPad sims so that they don't have to follow the FCC rules? and to preemptively stop those users from putting the unlimited iPad sims into other devices? AT&T's description of my plan is: "Unlimited MB for 30 days - LTE" I have a screen capture, of course for later reference.
