I recently upgraded from a Samsung Galaxy S3 to a Galaxy S4. Since the change, my friends on A&T and Sprint do not receive my MMS messages but my Cricket users are receiving MMS. My friend on T-Mobile did receive a MMS message on Tuesday night but he did not receive test MMS today. I didn't have this problem with him when I had the S3. I still have the S3 and tested sending with it on Sunday and the MMS was sent and received. I called Support and another phone was sent to me but I am still experiencing the same issue. I can receive MMS messages from others, regardless of the provider.
The reason I upgraded was because I was having an issue with the charging port on the S3 and I thought “Why not upgrade?” Now I am regretting this decision. I had insurance on S3 and should have used it but I was anxious for the S4 because of the better camera. I am very frustrated with this situation.
