United Mobile+ (new service with +44 Jersey number)

[inquisitor]

UM+ has not been working in Bulgaria, since I arrived on Saturday.

Allthough I'm booked on the only roaming partner's network (M-Tel, MNC: 284-01) I'm unreachable for callers and consequently also for the callback. Callers either hear nothing, or a busy tone or an announcement, saying the number is currently not available.

Outgoing calls are not blocked as usual, but I hear an announcement of the local operator ("your account has been suspended").

Callback requests by USSD (*131*number#) are terminated with the correct message "Thank you for your request", but I'm not being called back.

Balance requests by dialing 089 result in a busy tone, but the balance SMS arrives.

Incoming and outgoing SMS work flawlessly.

Since today callers from Germany hear an announcement of the Bulgarian operator in Bulgarian and thereafter in English language, saying an invalid area code was dialed, allthough they've properly dialed my UM+ number.

EDIT: The phenomenon described above occurs, when my UM+ SIM is booked in the Bulgarian network. If the phone switched off callers hear a three-tone-signal followed sometimtes by a message saying the dialed number is invalid.

um+ seems to have every day some new problems

[inquisitor]

Today it's my fifth day in Bulgaria and UM+ still doesn't work nor have I received any feedback on my complaints, which I first registered on Saturday afternoon and specified with additional details over the last days.
Since today callers hear an announcement saying "your account has been suspended", which I only heard when I tried outgoing calls before. Actually a bit embarassing for me if I'm called by business partners, whom I left my UM+ number, too and a shame for UM+, that they can't even setup an "unavailable"-message in such cases.
As the only Bulgarian roaming network "M-Tel" is owned by Mobilkom Austria, which in turn owns Mobilkom Liechtenstein and so the platform of UM's +423 service, these problems with the competing Jersey Telecom-based UM+ SIMs could be intentional.
Anyway UM is disappointing very much this time.

After five days in Bulgaria, where UM+ didn't work until my departure despite of my complaints, I'm back to Germany, where I noticed, that callers are still told my number was invalid, while I'm unreachable. Except for that UM+ worked in Austria, where I changed planes and here in Germany, too.
Does the unavailable-announcement work for you guys?

[fedeprovenza]

No, i've never heard this announcement (Italy and France). I'll try again the next week in France

I've just checked what happens when I call my switched off UM+ phone through several providers and that are the results:

PSTN operators:
Deutsche Telekom (ISDN): unavailable
Arcor (ISDN): invalid number

mobile operators:
T-Mobile Germany: unavailable (in English only!)
Vodafone Germany: unavailable
E-Plus: unavailable
O2 Germany: unavailable

VoIP providers:
Arcor (VoIP): busy signal
bellshare: invalid number
Betamax: nothing (silence)
dus.net (afaik using Versatel as carrier): busy signal
sipgate.de: invalid number

Maybe you guys could test it through your providers and continue my list.

From Canada to my UM+ number I get a message in German that sounds like the number is unavailable. My German isn't very good so I'm not sure if they mean the number invalid or that there is no answer. (I never enabled voicemail after UM made that feature available last year.)

Would be helpful for UM if you gave the operator used for calling, like I did above.

Btw is any technician of UM reading here?
