My MMS messages don't reach recipients

[Ronshirt]

Hi,

I've just switched from a PlusOne to a Samsung S7 Edge. I recently tried to forward a text message and it seemed to go ok. Although it appears to have sent the message it did not turn up on the recipient's iPhone. Her phone seems to be OK and is MMS enabled.
I'm a bit stumped by this. I don't normally use MMS so consequently don't know much about them.
I'm in the UK with Vodafone.

I've had this issue - try changing messaging apps. Also, make sure you haven't modified the MMS settings.
