Hi Notrepaired,
We want to help you get your iPhone working.
If you're seeing no internet connection, that often is a software or configuration issue.
Is this happening on every Wi-Fi you use?
Here's more information for how Wi-Fi networks can be configured to be most compatible:
Recommended settings for Wi-Fi routers and access points
Make sure to disable and remove any VPN apps or profiles that might be interfering with connectivity.
If you restored a backup to your iPhone, it's possible the backup itself contains an error or configuration that's causing the issue as well. Try setting up your iPhone as new to test the connectivity.
To follow up with questions on your repair, you need to contact Apple Support:
