iMessage Selectively Not Functioning

[UneElle]

iMessage has worked perfectly for me since I got my 4S, sending all texts to my sons, husband, and friend, all of whom have iPhones as iMessages rather than as texts. But suddenly yesterday, messages sent to my friend's iPhone from my iPhone are being sent as regular texts (green bubble) and when I sent a text to her iPhone from my iPad 1, she got it but could not respond.

iMessages are still being sent properly to husband and sons' iPhones.

Any ideas or help greatly appreciated!

It's probably a bad data connection on her end. Especially since you said she couldn't respond.

Thanks so much for the quick response!

Yeah this has happened to me and my buddy. Tell your friend to switch airport mode on and off and see if it fixes it. I usually only have this problem when I'm on 3G and not wifi.
