I have recently encountered an issue with picture messaging. I was sending images to another iPhone user, who was initially receiving the images. All of the sudden they informed me that the images I sent were not going through. The images appear to have gone through on my end but the recipient is not getting the images. I am not sure who their service provider is but I have tried all the fixes on my end to no avail. Has anyone else had this issue? What can I do to resolve it?
