iMessages not working properly

I need help as my messages between iPhones don't send as iMessages from my phones number since I changed to Lebara , they either send as texts messages or as iMessages but from an iCloud email instead of from my phone number. How do I change this? Thankyou

To fix iMessage after porting your number, update your phone number in Settings > Phone > My Number to ensure it matches the ported number, not a temporary one. Toggle iMessage and FaceTime off and back on, restart your phone, and allow up to 24-48 hours for the network transfer to fully register with Apple servers.
Step-by-Step Troubleshooting Actions:

• Toggle iMessage/FaceTime: Go to Settings > Messages, turn iMessage off. Go to Settings > FaceTime, turn it off. Restart the phone, then turn both back on.
• Reset Network Settings: Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings.
• Sign Out/In Apple ID: Under Settings > Messages > Send & Receive, tap your Apple ID and sign out, then sign back in.
• Check Date & Time: Ensure Settings > General > Date & Time is set to "Set Automatically".

• Verify Number: Go to Settings > Phone > My Number . If it shows a temporary number, change it to your ported number.

This works. I did it myself a month ago. It took around 30 hours so don’t expect an immediate fix. Ride it out. I know it’s a pain but it works. All the best
