I'm having the same issue down here in Atlanta. UMA's been working fine until now...Wake up this morning, and no UMA... Keep getting those same error codes.. The device is trying to connect, but no success. I called T-Mo CS... First Rep did the same thing, blamed my non T-Mo router.. (I have a NetGear btw). Called back for another rep who was more knowledgeable and helpful. After doing some tweaks to the device, he found out that there are some UMA outages over the US... I'm guessing this is the culprit.. However, I am not still not satisfied... Anyone else having these issuses?

Thanks!
