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.

New York City....Friday 10 August 2007 0026...

My phone still gets "your international call cannot be completed as dialed. Please check the number and dial again or ask the operator for assistance." when dialing a UM+ number with the phone off. No response yet.

Interesting.....here in New York the phone roams on both T Mobile US and also sometimes AT&T which is what I see on the screen...(it also says United Mobile below something the +423 card did not...something for example o9 does but others don't)...but interestingly enough in my apartment, my cingular phone still says cingular and not AT&T...doesn't really make sense eh.

Finally got thru to CS. The guy said the were having (have had?) problems with the web activations where it didn't always go thru properly and it leaves the SIM somehow blocked. So he cleared the block and called me back to test (which cost me a couple bucks :( ) and now it works.

I asked him about the voice mail problem and he said they knew about it and it won't be fixed for "a month or two". Ouch!

I didn't know they had that sort of accent on the Isle of Jersey :)

Their phone support is not based there probably but in Switzerland or Liechtenstein

Yes. The voicemail problem will not be fixed for about 1 - 2 months. Here is the response I received below. So, with the very inconsistent caller ID and no VM, it makes it not a very good option even if one leaves the phone on 24/7. Callers from the US expect to hit voicemail when you do not answer, out of coverage, etc.

At least some kind of system message that the person is not answering or so would have been better. It's obvious that UM rushed it to the market. I guess they figured, as already mentioned, that their profits were eroding quickly with that +423 number and they had to act quickly.

In Southern France UM+ subscribors were again unavaliable yesterday and I heard the bitone all the time, when trying to call them.

They should call it "free betatest" instead of "free upgrade" on their website.

As a postscript I finally got through to customer services this morning (!)

SIM re-activated and all is well for outbound calls. Inbound are NU here in France, but should clear when the HLRs update...

Steve :)

I've called to CS, 5 minute to reactivate the 2 sim card, they have a lot of work (maybe a lot of not well activated sim), so they not answer the mails, but works a lot on call center.
So who want to be reactivated the sim, must call, at this moment.

can you receive sms?i've some problems with my new um+, 'cause it can't receive sms

UM+ works in Turkey. Just called friend of mine, who has my SIM card.

BTW I just called twice over. Once from O2 mobile, once JUSTVOIP. And even my man in Turkey said JUSTVOIP quality of sound was far better. So it looks like Betamax have made some changes in carriers again.
