need help with imessage

[jemr]

Yet again an issue with imessage.

This morning i sent an imessage, for some reason it was unable to be delivered and asked if i wish to send it as text msg. Since then it will no longer send imessages to this contact (not event written imessage in the box bollow is now written text message). How do i go back to the imessage?

I have checked and it is on in the settings and I am able to send imessages to other contacts. I have also tried to reboot my phone and nothing happened.

Please help, tks!

btw i have an Iphone 4s

Could be your contacts phone was turned off or out of service area. Get him to send you a text and all should return to normal.
