My new iPhone is not finding my old iPhone through bluetooth

You can't directly activate a new iPhone using your old iPhone. Activation typically involves connecting to your carrier's network, and your old phone won't be able to do that for the new one.

Activating Your New iPhone

Activating your new iPhone connects it to your carrier's network, allowing you to make calls, send texts, and access mobile data. To activate:

• Connect to Wi-Fi or use cellular data: Choose a Wi-Fi network or, if available, use your cellular data plan.
• Follow on-screen instructions: The iPhone will guide you through the activation process, which may involve entering your carrier information and SIM card details (if applicable).

Once Activated: Setting Up Like Your Old iPhone

After successful activation, you can now leverage your old iPhone for a seamless setup:

1. Quick Start (iOS 11 or later on both devices): Bring the iPhones close together. The new iPhone will display an animation, and your old iPhone will prompt you to authenticate using Face ID or Touch ID. Follow the on-screen instructions to transfer settings, Wi-Fi passwords, and iCloud Keychain data.
2. Restore from Backup: You can choose to restore from either an iCloud backup or one created on your computer using iTunes. This will transfer all your data, apps, and settings, replicating your old iPhone on the new one.

In Summary:

1. Activate your new iPhone first (Wi-Fi or cellular data).
2. Utilize Quick Start or restore from a backup to personalize your new iPhone like your old one.

I hope this clarifies the process!
