To fix the FaceTime activation message, follow the steps below:
1.) Turn on WiFi by going to Settings > WiFi and connect to your local WiFi network.
2.) Go to Settings > General > About and wait here (about a minute) until you receive a carrier update prompt. After the update, the carrier field should say xxxx 7.2″, where xxxx is your carrier name. If the carrier says xxx 8.0″ or later, continue to step 3.
3.) Now go to Settings > Phone. Turn off FaceTime and turn off Show My Caller ID. Then, turn iPhone 4 off (slide to power off method).
4.) Turn iPhone 4 back on. Go to Settings > Phone. Turn Show My Caller ID back on and turn FaceTime back on. Make a call to another iPhone 4.
5.) If you are running iOS 4.1 or later, go to Settings > General > Reset > Reset All Settings.
Will iMessage allow for free texting between people in America and others in Europe, for example?
Why can you choose a Location on the iMessage Account?
If you go to the Message Settings and press Receive At and then press Apple ID, there you'll be able to Change Location.
There it says:
"Choose a country or region to allow iMessage to message local number in your address book."
What is this for?
Does my carrier need to support this new feature?
It still does not activate.
I have 3GS so no facetime.
Just would like to have iMessage activated.
I just got the message unable to activate.
I hope it isn't a having GM issue...
Am I being stupid, I have not iMessage app on the iPhone, how do I use it?
iMessage is inside the Message app itself.
Go to Settings -> Messages and check if iMessage is turn ON and ACTIVATED.
iMessage is on and it does not say anything about being activated. The message app looks the same as it did before iOS5. :s
