Error: Connection problem or invalid MMI code

[Guest rkn_se]

Hi!

I can't use the dial prefix *140# - it's required to have the call debited to my private phone bill. I'm using MoDaCo r4 on my SF/ZTE Blade.

It seems to have been a common problem for android phones. I've seen some solutions to this problem (not for SF, but for other phones) but so far nothing works. Haven't tried to revert to the original Orange software yet...

Has anyone solved this?
