I can't send text on my V525, on the Vodaphone network in the UK.

My phone worked out of the box (on a monthly contract) but I need to
change some setting to get the text and photo messaging to work.

I've phoned up the helpline twice, and got 2 different fixes, neither
one worked.  The second lady admitted that they didn't actaully have
the settings info for my phone, but would use a 'similar' phone.
Unfortunately, it's not similar enough, as she referred to menu
options that don't actually exist on my phone...

Has anyone had to alter their phone to get it to work ?  If so, what
did you do ?

Thanks.
