Hello j3nG,
iMessage is a great feature, and we know how important it is to get iMessage activated on your device. We're glad you had the opportunity to try some troubleshooting steps, and we want to make sure we don't repeat those steps. Did you try the steps outlined in If you get an error when trying to activate iMessage or FaceTime?
If you've already tried those steps the next step is to get you in contact with one of our other support channels for additional assistance. You can find our available contact options through our Get Support website.
Have a great day!
