Text messaging to Other than iPhones
Recently, when I send a text message With a picture to a phone that is not an iPhone, Does not send.
Also if I send a text message to more than one person, to three people, and one of those people is not an iPhone it also does not send.
When I take the phone number out of the text message That is not an iPhone the message sends.
This has only started recently in the last few weeks
iPhone 5c, iOS 10
