That never occurred to me (do not reset the unit) but it's a good thought... if you reset the unit then everything goes back to factory default, and without a GUI option to reset to unlimited then... you're not going to be able to set to unlimited ever again. I'm going to be sure to not push that button!That could well be. I had a habit of using the reset button on the side of the Mobley to restore connection when it was lost on the road. Now, when you use it, it will reset the max time back to 30 minutes from 2 hours. It may be that I unwittingly shot myself in the foot by using it after the update.
Maybe the moral of the story is don't use that button!
I have another mobley that I bought used but never had ATT provision. I wonder how dumb it would be to put the SIM from one of mine into it. They seem to make a big deal of the EMEI (spelling?) numbers being matched to the SIM these days.
Regarding the SIM/IMEI match, up to this point AT&T has not chosen to enforce that and you can pretty much swap a Mobley SIM into any device you want, at least on the network side that is, but note that there is one thing to watch though... with the latest Mobley firmware update AT&T secretly adds a SIM PIN to the Mobley SIM and doesn't tell you what it is, preventing you from moving the SIM. Sneaky bastards. But you can get around this by either:
1. If your Mobley hasn't updated yet, install a SIM PIN yourself, other than 1111 (the default.) If you set your own SIM PIN then the Mobley firmware cannot change it.
2. If your Mobley has updated you can call AT&T and get the PUK ('PIN Unlock Key') code for your SIM (all they need is the phone number assigned to your unit.) With the PUK code you can reset the PIN to something other than 1111 and then the Mobley cannot modify it again.
