I have nothing to offer to this thread but have to laugh because I don't think there is one sentence that I totally understand. To say I am a non-tech person would be a gross understatement but I do have an Advanced Ham radio license. The world of electronics has passed me by but I am glad to see that there are some who are beyond their teen years and do understand it all. Keep on keeping on guys - I may need an interpreter but there is no doubt a lot of value in threads like this one.

Bill, the excitement about AT&T and the Connected Car Unlimited plan is because it's the first time you can get unlimited mobile high speed Internet for $20 a month, no strings attached. Competing plans have a hard data cap and/or cost 4 or 5 times as much.
It's original market was OnStar equipped GM vehicles, but AT&T found an inexpensive ($99) adapter, the ZTE Mobley, that works in any car.
Then people figured out you didn't need a car, just a source of 12 volts to power the Mobley, and the race was on. People started offering power adapters on Ebay and Amazon and suddenly you could get unlimited high speed Internet anywhere there's an AT&T signal, not just in a car, but in an RV or even fully portable using a small battery or a computer USB port for power.
If you're interested, take a look at
this thread. AT&T has been overwhelmed by the demand for the Mobley, but as of now it's in stock and the $20 per month plan is available.
