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

[inquisitor]

Having just placed some test calls in Germany, here are the results, according to which UM+ does only work on a single German network (T-Mobile) flawlessly:

T-Mobile
callback by Call: +
callback by USSD: +
availability: +

Vodafone
callback by Call: - (call is being blocked, but no callback follows)
callback by USSD: +
availability: +

E-Plus
callback by Call: - (call is not being blocked, but announcement "barring service activated")
callback by USSD: - (USSD command remains without confirmation "Thank you for your request")
availability: +

O2
callback by Call: - (call is not being blocked, but announcement "number temporarily unavailable")
callback by USSD: +
availability: +

CLIP doesn't work for outgoing calls at all with any German operator.


Has anyone tried UM+ in Mauritius yet?

The last news from France with my um+ (Grenoble, Rhone Alpes region)
-roam on Sfr, Orange and rarely Bouygues
-call by callback: quite well (um+ shown the caller, but i can see um+ number on my italian sims).
Call quality is perfect (incoming and outgoing)

Today I arrived in Mauritius, where UM+ works comparably fine:

callback by Call: - (call aborts after quite a while without any callback)
callback by USSD: +
availability: +
outgoing SMS: +
incoming SMS: +
