Hello everyone,
I guess everyone is still waiting and hopes for his number, uh? Same here...
Well, I just tried to call my UM number... here are the updated results (tests took place a couple of minutes ago):
Calling from land line, rings perfectly... I even picked it up, and was able to talk. Making a notice here, that the voice was not delayed at all and it was crystal clear! (previously voice was kind of bad and with a lot of delay - up to 1-2 seconds... seems someone is working on it???

)
Call from my Vodafone mobile number, rings perfectly, and can speak - very clear too.
Send sms from my Vodafone mobile number, nothing is received.
From UM number though, I can place no calls, or send any sms...
Caller ID also works from my Vodafone mobile and land line.
