![]() My UM+ works almost perfectly on RAZR V3: the only problem is about displaying the credit expiry date. I can make and receive calls and make and receive sms.
I think things go better with brand new cards than upgrades from UM +423. The most important news is that now there is no more any message of non-existing number if I call UM+ with the phone swirched off: now there is a strange sound...not the best, but better than before! ![]() The customer care answered my later mail, saying they were applying to solve that problem, then advised me to use the sim menu to make outgoing calls with the 6510. What is annoying, is that I had reported that I wasn't able to make outgoing calls even with the sim menu...I wonder if they have read my mail carefully... |

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.
