I have to give a big thumbs up to Covert. In Bearclaw's thread below, Bornforit posted on the new data plans that Covert is offering which unless you're a pic monster, are a bunch cheaper than a new to ATT data plan.
I hadn't heard of them, so I called Covert and asked if you could use the new data plan with an older 2014-3G camera. You cannot, but they've sent me an RMA and for $150, I can trade-in my 2 yr old camera for a new one. You don't hear about service like that often, so I thought I needed to publicly thank and recommend them. Link to new current Code Black and data plan
