Here is my issue: I cannot send messages from my iPhone to Android devices that includes a picture. I always receive a "Not delivered". I have MMS enabled but with only 1 bar in LTE on my phone at my home, I am very dependent upon my WiFi (Fios) even for making calls. From what I have read, MMS only works on the cellular network but that means it is something useless to me based upon the very limited cell service I have. Is there any work-around for this? Do I need to drive to an area with better cell service so I can communicate with my sons and include pics?
