iMessage Won't Activate
Firstly, I have already followed all the advice in the forum, but to no avail.
I have an iPhone 6 running iOS 8.4
I recently switched service providers, while keeping the same mobile phone number.
During the switch-over, I was issued a new sim card, from the new service provider.
Ever since inserting it, I am no longer able to activate iMessage.
Interestingly, when I checked what my mobile number was, it was listed as BLANK / EMPTY.
I had to manually add it in.
I can make and receive calls / sms from the phone.
Simply, iMessage will not activate.
I contacted my service provider and they seem clueless and maintain it is not their issue.
I no longer have Apple telephone support, and online support, tells me to speak to my service provider.
Any suggestions?
