Why won't my iMessage work with only one contact in my phone all my other iMessages send and they just got an iphone but all their iMessages are sending also. I've tried restarting my phone, deleting messages, contact, restarting network

I Am having the same issue!! Nothing will fix this problem! I have deleted the contact and re-entered it and nothing! I do not have Preferences as an option under Messages either. I need help!!

I have the same issue as the OP. iMessage will not work with one contact only - my husband. I have tried all the troubleshooting steps suggested to no avail. This seems to be a real bug dating back a number of years based on the posts in the forum. It would be very much appreciated if Apple would look into this and come out with a proper fix.

I had this issue with just one contact, and the solution was that they had removed their email address from their iMessage settings, so I had to use their phone number for sending them iMessages.

I was easily able to see this and fix it on the Mac, not sure how one would do this on the iPhone etc.

Make sure that neither user has the other one blocked. This was the case on my girl friends phone. She swears she didn't block me.LOL She had other numbers blocked mysteriously too. Go to settings then messages checked for blocked numbers, under MMS/SMS, both phones. Note I'm not talking about the block on the contact pages, it's different. Good luck.

I had same exact issue and did everything I read from web short of reseting network or restoring phone. I had issue with sending message to husbands iPhone, my attempts to send messages from either my iPhone or iPad would not go by iMessage but mac would send without problem. I looked at his phone, and in his setting for messages his setting to initiate messages had icloud checked instead of iPhone. I placed check to initiate messages from iPhone, then sent a message to my phone and all worked fine since. Not sure why that made a difference but it did.

I am having this same problem with my father and his iphone. We both have the SE and verified all the password settings etc. He can call and text me (or ims me or whatever the proper terminology is for when you are text messaging another iphone user with your iphone) and I can call him but when I text him he is not receiving the texts. He can send and receive texts among other people and I can as well. It is just that my texts to him are not going through. At first I thought he had accidentally blocked me but I checked his phone and I am not blocked.

But my question is in regard to the solution about substituting a X for the last digit- how would that even work? Of course a text won't go through to a number with a letter in it or else with a 9 in it??? Then substituting a 0 is still the wrong number...? None of the tech people have been able to help me with this question.

Just had this issue and fixed it.

Messages>Preferences>[yourAccount]>Enable this account Uncheck this.

Facetime>Preferences>Turn OFF the switch and turn back ON.

II'm having the same problem!!

Worked! Apple support response was useless but this restored iMessage to the one contact without losing message history. Thx!

How exactly do you do this on your iPhone? I cannot find the preferences tab under messages. Please help!

Does this contact have an iDevice and is iMessage active on that?

My message still isn't sending I don't know what's going on so can someone help me.

I am also having this problem - I have read all the forums and went to the apple store, absolutely nothing has worked. if anyone has an updated answer please let me know ...

Same problem

Niether do I
