I'm using an iPhone 6 on 8.1.3 and formerly on 8.1.2.
I have previously successfully activated iMessage with multiple US carriers and with Rogers on the same phone.
My number is a new activation NOT ported over.
I have been with Wind since Dec 2014, and I am on a prepaid $44 Unlimited plan that includes international texting. I even have $9 extra just incase.
All features are active on my account. I even tried disabling and enabling them.
My number is correctly displayed in phone settings as +1 (647) xxx - xxxx
My timezone is correctly identified.
I have tried resetting network settings, and even 'Reset All Settings' multiple times.
I have tried multiple fresh installations of iOS without restoring from backup and just setting up as new phone.
I have tried playing around with apple ID (changing password and even creating a new one)
I have tried the process without being signed in to FT and IM with my apple ID.
My apple ID has my number correctly stored online under mobile number.
I have successfully sent/received SMS to people overseas.
I have tried all methods with the correct APN settings and with/without MMS settings.
I have tried the Developer Telephony Logging and the manual method.
I have tried multiple times since the end of December, with long breaks in between due to frustration.
I have contacted Steve, who has been very nice, he suggested alternating between activating FT and IM.
I have contacted WIND multiple times they assure me that the problem is with Apple. Apple's level 2 techs have walked me through the same repetitive procedures with no success.
I have waiting as long as 1min, 5 min, 10min, 30min, 1hr, 2hr, 3hr, 4hr, 5 hours and even logging until IM/FT indicated activation unsuccessful MULTIPLE TIMES.
I have followed all instructions from all sources exactly as written.
NOT ONCE HAVE I SEEN A hex str from the +44 number. I only ever see SMS messages in the logs from known contacts.
I can see all the outbound request being sent to +44 numbers.
I even tried deregistering my number with iMessage, the strange thing is I do not get a response like other that my number is not registered, nor do I receive the text containing the code. I have also tried this multiple times over the past two months.
Frustrated out of my mind, I still can't figure out why this is not working for me.
