I have an iPhone and have friends with iPhones and sometimes my messages go to them as an iMessage and some go to them as a text message. And sometimes when they send messages to me it’s the same thing but it’s not every message on every person.

I have friends with iPhones that every now and then a message I send will not go as iMessage it Hass to go as a text. But it’s not every time. I have one friend that says she has enabled her iMessage but when I message her it always rejects and I have to send it as a text but when she sends it to me it comes through as an iMessage. And some of my friends that have iPhones there box doesn’t come up and I can’t get messages to them and I can’t receive messages sometimes for a while it’ll just spend . any ideas?

If you can't send or receive messages on your iPhone, iPad, or iPod touch - Apple Support
