Picture not delivered to a certain fido customer

[RajR]

I have an iphone 4 and i m a fido customer. I was able to send the picture message to myself and my wife's Chat-r mobile phone without any issues. I have tried restarting my phone and sending again but not luck! If somebody can help me figure out what's wrong. I am assuming it's the receiver's side issue. But just want to make sure before i tell them. The receiver is also with Fido and on iPhone 5S. Is it because they may have blocked data on thier phone? or is it a compatibility issue iphone 4 to iphone 5s? Or something else?

Please help me, Fido Community!

If you can successfully send to yourself and receive it, the issue is most likely on the receiver's end. There are many possibilities; data blocked, no access to that service, etc etc.
