Can all of my devices on my Apple ID account see all my messages on imessage?

All iMessages can be seen on all your iOS devices. Just note though that any messages sent via SMS won't be.

I'm not sure that is correct, what about messages received at a phone number when viewed from an iPad.

Yes, they show up as well. As long as they have been sent via iMessage and not SMS.

It isn't the case for me. If someone sends me a message to my phone using my phone number, it does not show up on my iPad.

Well, it does for me. For example, messages with my son show up as 2 categories on the iPad, one with his name as email address, and one with his phone number. Although these are integrated on my iPhone, they show up separately on the iPad which is annoying.

iMessages to phone numbers also show up in Messages on my Mac OK. As long as they have been sent as iMessage and not SMS, it should work.

I see much the same thing, but when someone sends me a message to my phone number it does not show on the ipad unless a conversation is already in progress. I'm unable to replicate what I think you are telling me, one of us is misunderstanding the other.

I'm not sure where we are on this. All I know is that with the 7 or 8 people I have regular iMessage conversations with, I receive all messages on my iPad (and Mac) whether they are sent from a phone number or an email address.

I'm confused!

A couple of weeks ago, I was able to see messages on all my devices, but yesterday I got a message on my iPhone only. Is there a way to fix this? (I'm referring to iMessage only).

I was talking about messages sent to a phone number rather than from a phone number.

Yes, with existing conversations I've seen the iPad pick up messages sent to my phone, but never when there is no existing conversation.

Still not sure about this.

From my iPhone, I have just send a iMessage to my own phone number when there was no previous conversation - talking to myself would be worrying! - and the message appeared instantly on my Mac, iPhone and iPad.

Yes, but you are presumeabally sending it from the iPad using the email address that your mac message application is also using.

I'm not to sure about it all either, it seems somewhat inconsistent, I think I know how it should work, then something doesn't happen that I expected would.

I don't think it's safe to say though that all messages to and from one device show up on all others.

Sorry Winston, but as I said in my post, I sent it from my iPhone to my iPhone phone number. No email addresses involved.

Sorry I didn't see that bit, but have just tried to replicate what you did. Yes, when I send a message from my own phone to my own phone using the number, it appears on my iPad. However as I've said before when someone else sends me a message to my phone it does not appear on my iPod. I think the situation of sending a message to yourself maybe a part key to the difference and quite honestly an unusual circumstance in any case.

Perhaps it depends whether the other person also has your email address keyed into their contact list along with your phone number or not.

Hmmm, I think you're right. I've just deleted all conversations with one of my 'regulars', then asked him to send iMessage to iPhone number, not email, and it didn't come through on my iPad or Mac.

Why on earth will it work if a conversation already exists, but not otherwise? Also makes me wonder how the conversations appeared on the iPad in the first place?

Does your friend have your email address in your contact file on his device.
