Hey, so my Mum got this nice new XT phone. And I sent here a couple of images via MMS from my iPhone 3G.

She gets a message notifying her of a new MMS, at 340KB or so (the Telecom R7 shows you the image size it seems). But when she tries to download it, it says "message exceeds size" or something. Basically - too big to download.

Is this a network issue for XT, an issue with sending images VFNZ => Telecom, or a phone issue?

Here's an example image that wouldn't come thru ... I MMS'd this to myself so that any transformations in the MMS route would happen (but it's been sent from VFNZ to VFNZ instead of from VFNZ to XT).

I'll get someone to look into this issue for you.

I am sure that Telecoms CDMA network limited MMS to 250KB. Not sure if the same applies to XT or not (Im pretty sure I have sent 350KB+ MMS on XT though).

Thanks both of you guys - any input would be great.

Yeah ... I sent another picture which *did* get through, and it (well, the original file) was 646KB. The one I linked above shows up on my computer as 750KB. So I'm a bit perplexed why the R7 said the image was around 350KB.

I've used other phones which allowed me to specify the details of the sent MMS, but of course Apple's business model is not really based around being friendly to other devices, is it? :D

Still, it would be a real bugger to be on a phone network which didn't cope with the MMSs you were sending or receiving. And I know Telecom are loving that people bring their iPhones over to play on XT.

I'm sure all networks have their size limit - would be good to know what they are, and if I can work around them somehow.

TELECOM XT - Haven't researched MMS much but from what I can tell the phone will be set from factory to a defined image size for sending, this is usually 300KB. When you try to send an image larger than this some phones will automatically resize the image, some wont, both will still be sent.

When it gets to the MMS server it will find a user agent matching up to the receiving device, in this case your sending from a Iphone which I think has a image limit of 600Kb* when you send this you the R7 it will still send 600Kb but when it gets to the server it will resize the image so it can be viewed on the R7.

The internal image resizing doesn't appear to be working for VFNZ to TNZ or visa versa.

will look into this more.
