I also now can receive SMS on both. One funny thing -- when I first turned on the UM+ upgrade it said "AT&T" as the network name. The new UM+ says "Cingular." At some point the AT&T switched to Cingular and now I can receive SMS's -- probably a coincidence, but who knows ![]() I am thankful that I didn't xfer my balance from the +423 card! |

My my upgrade-UM+ now also has this strange two-tone signal when unavailable since it has been reactivated.

What's probably happening here is that it's changed from using one network to the other. Some time ago Cingular (PacBell) sold part of their network in California to T-Mobile. I beleive this network has been running with the old PacBell MNN which may show up on most phones as Cingular. ITMT, Cingular is also running a different network in California with their regular MNN. It's all very confusing because the name comes out of a lookup table in the phone and if the company changes its name (e.g. ATT => Cingular => ATT) the phone does not know about it. OTOH, the name shown for a SIM's home network can be changed by an OTA update.
