This would happen 9 times out of 10. At one point I got so frustrated that I switched to my Mobal SIM and made the call using it despite the much higher cost. Calling 089 to get a Balance Update worked just fine.

Anyone else experience this situation or have any advice on what to do when it happens?

Last year when I had the old UM Liechtenstein SIM and used the same phone the call back mechanism worked flawlessly both within Europe and to Canada.

Use *137* code (as I described above). It may be a network issue, too. In another very long UM+ thread I told that using UM+ in one of three Polish networks is affected by the same problem (even menu based calling fails in the way you described). However, *137* code works.
