Wife and I have been using iMessage all day long on iOS 5.1 with no problems.
My wife upgraded her iphone 4 to 5.1 yesterday and every message she sends me (4s on 5.1) shows up as a text message. even when the phones are an inch apart on the same wireless network. any suggestions? I've tried rebooting etc...
Get your wife to send a message to her own number,
Edit: Make sure imessage is turned on and activated to the phone number of your phones.
I have had the same issue, and so has my wife, both a different times, and we both had our iMessage activated through our email address... the above step fixed us both.
I think it kinda sucks as a solution, but it works. My question then is how are people on desktops and ipads supposed to find us to use FaceTime? Hopefully as a secondary address, and I still have my "caller ID" as my email address.
I've been having the same problem since updating to 5.1. iMessages will send as blue, I'll get "delivered" under it and then moments later it reverts to a green bubble and "sent as text" it's quite annoying. I believe the reason is due to the fact that there's no longer a "try again as text message" option and it's forcing the message out over text.
I had it resolved for about 8 hours and then when I woke up in the morning it was back to sending as text. I don't usually complain about iOS issues but this one is my biggest problem. Anyone try doing a DFU restore and set up as new?
