Help Cannot send sms to one contact

[jonpeck]

I have a HTC desire on orange and my brother has samsung galaxy s on o2.

Whenever i text him it comes up with the red triangle and !. I have deleted him then added him again and still it persists.

He can send me texts and we can call each other. I have other friends on o2 and we can send texts.

Any help is welcome.
