Do I have to buy the €1 extra credit every time I want to use imessage or is once enough?
Great stuff SimranjeetS6151!
Adding €1 to my account, even though I was on the €7.99 a month plan solved the waiting for activation issue for iMessage and Facetime. (8c cost to send activation message to Apple)
Was bugging me for 2 weeks having followed all the other steps previously.
