Repair Troublesome iOS & Android Issues at Ease

Setup Assistant involves several stages, and each can fail for a different reason. Quick Start depends on your old iPhone, activation connects to Apple’s servers, and eSIM setup relies on your carrier. Identifying where the process stops helps narrow down the cause instead of assuming your iPhone 18 Pro stuck on setup has a hardware problem.

This guide covers 7 practical fixes for Quick Start, activation, eSIM, updates, and frozen setup screens. For repeated software freezes or crashes, you’ll also learn how Dr.Fone - System Repair (iOS) can help repair underlying iOS issues.

Part 1. Which iPhone 18 Pro Setup Stage Is Stuck?

An iPhone 18 Pro setup stuck on Quick Start can have a different cause than one stuck during activation, eSIM setup, or a software update. Identify the exact stage where the process stops first. The table below can help you match each setup issue with its likely cause and the best first action:

Part 2. How to Fix iPhone 18 Pro Stuck on Setup?

Once you identify where setup has stopped, choose the fix that matches that specific stage. Whether your iPhone 18 Pro is stuck setting up during Quick Start, activation, or an update, addressing the actual cause can prevent unnecessary resets.

Fix 1. Fix Quick Start or Data Transfer Stuck on iPhone 18 Pro

First, confirm whether the transfer has actually stalled. Apple says transfer times can vary based on network conditions and the amount of data being moved. During a direct device-to-device transfer, both iPhones remain occupied until the process finishes.

Make sure Wi-Fi and Bluetooth are enabled on your old iPhone. Keep both devices nearby and connected to power. If the Quick Start prompt disappears, restart both iPhones and try again. You can also choose an iCloud-based transfer if available.

Fix 2. Fix iPhone 18 Pro Stuck on Activating

An iPhone 18 Pro stuck on activating may result from Apple’s activation service, network problems, or a SIM/eSIM issue. Start with the solutions below to check the activation service, refresh the connection, and activate the iPhone using a computer if needed:

1. Check Apple's Activation Service: Open Apple System Status and check “iOS Device Activation.” If it isn't green, Apple recommends trying activation again later.
   
2. Restart and Change the Connection:

   1. Step 1. Hold the “Power + Volume Up” buttons and slide the “Slide to Power Off” slider.

      

   2. Step 2. After 30 seconds, press the “Power” button and connect it to a reliable Wi-Fi network when it turns on. If the activation server is temporarily unavailable, wait a few minutes, then try again.

      
3. Try Activation with a Computer:

   If the iPhone still won’t activate, connect it to an internet-connected Mac or PC and locate the device on your computer. Wait while the computer detects and activates your iPhone 18 Pro. If Apple says “Set up as New” or “Restore from Backup” appears, the iPhone is successfully activated.

Fix 3. Fix iPhone 18 Pro Stuck on Cellular or eSIM Setup

When your iPhone 18 Pro is stuck setting up cellular service, start by checking your carrier, cellular plan, and internet connection. Apple recommends several checks when eSIM activation fails. Try the following actions to resolve the issue:

• Check Your Plan and Carrier Support: Confirm your cellular plan is active and your carrier supports eSIM on your iPhone model in your region.
• Check the Connection and Retry: Connect the iPhone to Wi-Fi or a hotspot. If activation still fails, turn Airplane Mode on and off.
• Contact Your Carrier: If the eSIM still will not activate, Apple recommends contacting your carrier. They may need to check your account, coverage, service status, or eSIM setup details.

Fix 4. Resolve Apple Account Sign-In or Activation Lock During Setup

Apple Account sign-in and Activation Lock can both prevent setup from continuing, but each requires a different approach. If your iPhone 18 Pro setup is stuck at either stage, use the solutions below to resolve the specific problem and continue setup:

1. Check Your Apple Account Sign-In: Make sure the iPhone has a stable internet connection. Then, enter the email address or phone number and password associated with your Apple Account.
2. Recover the Account or Set It Up Later: On the Apple Account screen during setup, tap “Forgot password or don’t have an Apple Account?”. You can then recover your Apple Account or password, create a new Apple Account, or choose to set it up later.
   
3. Remove Activation Lock Properly: When “iPhone Locked to Owner” appears, ask the previous owner to remove the iPhone from their Apple Account. Device owners can use Apple’s supported Activation Lock removal process and provide proof of purchase when required.
   

   Note: For the detailed guide to remove the Activation Lock, follow this Dr.Fone iPhone Unlock Guide.

Fix 5. Fix iPhone 18 Pro Stuck on Software Update During Setup

For an iPhone 18 Pro setup frozen during a software update, first check whether the update is still progressing or has failed. Keep the iPhone connected to power and reliable Wi-Fi. When an update error appears, retry the update before moving to other solutions.

A backup created with a newer iOS version may also prevent restoration during setup. Apple recommends temporarily choosing “Don’t Transfer Apps & Data.” Follow the steps below to use this workaround:

1. Step 1. On the “Transfer Your Apps & Data” interface, choose “Don't Transfer Apps & Data.” Complete setup temporarily and skip the Apple Account, Face ID, and passcode.

   

2. Step 2. Connect to a strong Wi-Fi network once you are on the Home screen and go to “Settings > General > Software Update > Update Now.”

   

3. Step 3. Following this, choose “Settings > General > Transfer or Reset iPhone > Erase All Content and Settings > Continue.” After the iPhone restarts, run Setup Assistant again and restore the backup.

   

Fix 6. Force Restart a Frozen iPhone 18 Pro Setup Screen

When iPhone 18 Pro setup is taking forever and the screen no longer responds to taps, a force restart may help. However, wait if the screen remains responsive or the setup progress is still changing. For an unresponsive setup screen, follow the steps below to force restart your iPhone 18 Pro:

Instructions. Quickly press and release “Volume Up” and “Volume Down” > Hold the “Side” button until the Apple logo appears. After the iPhone restarts, continue through Setup Assistant and check whether you can move past the previously stuck screen.

Part 3. Should You Wait, Restart, Erase, or Fix an iPhone 18 Pro During Setup?

When iPhone 18 Pro setup is taking forever, avoid restarting or erasing the device while setup is still making progress. The right action depends on whether you need to wait, restart, fix iOS issues, or erase the device. Use the table below to choose the appropriate action based on what happens during setup:

Part 4. Why Is iPhone 18 Pro Setup Taking So Long?

To understand why your iPhone 18 Pro is stuck on activating or setup takes longer than expected, review the common causes in the table below:

Part 5. Why Does iPhone 18 Pro Setup Keep Freezing or Restarting?

The following points explain why your iPhone 18 Pro is stuck setting up or keeps freezing even after trying the recommended fixes:

1. Setup Assistant Stops Responding: A temporary process failure can freeze the setup screen even while the iPhone remains powered on.
2. Apple Verification Cannot Complete: Activation or Apple Account verification may stall when the device cannot complete a request with Apple’s services.
3. Quick Start Keeps Disconnecting: Data migration may stop or restart if the two iPhones lose their required connection during transfer.
4. An iOS Issue Crashes Setup Assistant: A system-level software problem can repeatedly freeze, crash, or restart Setup Assistant at the same stage.
5. Hardware Problems Become More Likely: Hardware should be considered if setup still fails after software recovery and external causes have been ruled out.

Part 6. When Should You Stop Setup Troubleshooting and Get Help?

If your iPhone 18 Pro setup is frozen after trying the recommended fixes, certain signs may indicate that further troubleshooting will not resolve the problem:

Conclusion

When an iPhone 18 Pro gets stuck on a setup issue, first identify the exact frozen stage. Most delays point to Apple servers, your mobile carrier, or your old phone, not a broken device. If crashes continue after checking external connections, iOS software might be the cause. Once you rule out external factors, tools like Dr.Fone - System Repair (iOS) can safely fix software loops and get your phone past the setup screen.
