925 with GDR3 preview has no Visual Mailbox in T-Mobile Germany (but 920 with GDR2 has)

[wptom]

I have a Lumia 925 with GDR3 preview. With my T-Mobile Germany SIM card inserted the phone does not have the Visual Mailbox.

However, if I insert the very same SIM card into my Lumia 920 with only GDR2 there is the Visual Mailbox.


I rebooted the 925 several times and both Lumias run the carrier free "CV DE" firmware. (But the 925 was originally a Vodafone device in case that's important.)

Does anybody know why the older phone has VM and the newer one has not?

Not sure why, but my L925 only shows Visual Mailbox with Telekom DE Software, not with the CV DE Firmware.
