I can't successfully send a pic message using MMS when the pic size is > ~ 300kb. I spent the prerequisite hour on the phone with VZ tech support ....

I do not have a data block
I have the unlimited data plan, and unlimited text/pic messaging on all phones
Works most of the time with a smaller picture (~100kb)
Fails 100% of the time on pics > 300 kb

The VZ tech swears that this is a Samsung issue, not a VZ issue, and is applicable to all PDA phones - the PDA somehow restricts the size of the attachment to less than 300kb. VZ says there is no solution. I can apparently receive a pic message with a pic >300kb, just not send one.

Is this actually true? Any solutions? Thanks guys/gals.
