Virgin sim problem - Voicemail

[Guest jbhq]

(realise that Virgin use T-Mobile - may be confusing me)

can't pick up voicemails (4400...11026? T-Mobile?) - number barred

tried changing voicemail number to my own (phone off)

but this is overridden to original 11026 on bootup

Can't change Voicemail "My Carrier" button

Tried using SmartSim (properly seated) - same results

Tried T-Mobile AND Virgin APN setups - no difference

Network states Tmobile.uk whatever I change

can pickup voicemails ok with sim in my old phone

Ebay phone (no T-Mobile sim) on v2.1

can anybody point me forward? :huh:
