Hi Nomi01,
Welcome to Apple Support Communities. I understand that you're having trouble activating your iPhone and even after connecting to iTunes, you're still having trouble. I know how important it is to be able to activate your devices; I'd like to help. Based on the steps you've taken so far, I'd recommend using the steps below:
- To check for network or activation issues and see if you need to replace your SIM card, contact your carrier.
- Use recovery mode to restore your iPhone.
If restoring your iPhone still doesn't work, contact Apple Support."
If you can't activate your iPhone
Best Regards.
