Hello shlomi2890,

To resolve your issue, you would need to change the Apple ID back to what you had originally, sign out and then change it back. Check out the article below for more information.

Change your Apple ID temporarily

If signing out and back in to iMessage or FaceTime didn't help, try these steps:

1. Change your Apple ID to the Apple ID you used previously. You shouldn't need to verify the email address.
2. Go to Settings > iCloud. Complete these steps only if the Find My [Device] setting is turned on:

• Scroll down and tap Delete Account, then tap Delete to confirm. 
• Tap “Keep on My [Device]” or “Delete from My [Device].” In either case, your data remains in iCloud and will be updated on your device when you sign in to iCloud again.
• Enter the password for your previous Apple ID.

3. Change your Apple ID to the new email address that you want to use. You'll need to verify the email address.
4. Return to Settings > iCloud and sign in with your new Apple ID.
