MMS Picture Size too BIG

How are you resizing pictures on your iPhone before being sent via MMS?

The size limit for photos/video is automatic by AT&T since the MMS is originated through AT&T servers based on AT&T's limits at a minimum. Doubtful AT&T is going to set their MMS limit based on the lowest size required for a group of carriers or at least based on all U.S. carriers.

I don't MMS often but when I do, this is with friends and/or family members who are Verizon and Sprint subscribers and no such problem on the recipient's end with any photo I've send via MMS.

MMS size limit is determined by the carriers, not Apple. That's why there is no setting on the iPhone to do so as the carriers automatically re-size the pic to conform with their network standards.

Do you know which carrier or carriers these folks are with?

And do you know if they are using a "dumb" or non-smart phone, or a phone in the smart phone category?

I've never had such a problem - I've never had to re-size a photo that was sent via MMS which I've sent to AT&T, Verizon, and Sprint subscribers with no problem on their end. Most use a phone in the smart phone category which shouldn't make a difference but it might. AT&T does not have unlimited message size for MMS - a photo is automatically reduced to be below whatever AT&T's maximum size is.

Are all your friends having this problem or just friends (or a friend) on a certain carrier? Or is it possible a friend has a problem with their phone?

I've sent photos via MMS to friends and relatives on T-Mobile, Sprint, Verizon, AT&T and Altel with no issues whatsoever and I did not do anything to the photo other than take it and text it.

Not a problem with your iPhone. After a message is successfully sent, what happens to the message after that has nothing to do with the phone used to send the message.

If this worked 3 or 4 months ago for them, nothing has changed in this regard with your iPhone but namely with AT&T.

The problem lies at the recipient's end. You may want to ask your friends with this problem which carrier they are using. If Verizon, there is a simple step they can do with their phone - updating their preferred roaming list which will probably resolved the problem for them.
