Fix “Unable to Check for Update” on iPhone or iPad
Source-checked About 10 minutes
Answer
Retry on the same network, then another network. If the error remains, update with a Mac or PC; remove the downloaded update only after those checks.
Confirm the device can receive the update
Connect the iPhone or iPad to power, use a stable internet connection, and check Settings > General > iPhone or iPad Storage for adequate free space. Confirm the model supports the offered iOS or iPadOS release.
Retry Software Update once
Open Settings > General > Software Update and let the device check again. If Apple's update server is temporarily busy, wait and retry later rather than repeatedly deleting data or installing an unknown profile.
Test another ordinary network
Try a different trusted Wi-Fi network. Avoid captive portals, restricted work or school networks, and VPN or filtering configurations while testing; the device must be able to contact Apple's update service.
Restart and check again
Restart the iPhone or iPad, reconnect to the trusted network, then return to Software Update. Record whether the message is Unable to Check for Update, Unable to Verify Update, or another alert because Apple provides different recovery paths.
Update with a computer
If over-the-air checking still fails, back up the device and connect it to a Mac or Windows PC. Use Finder, the Apple Devices app, or iTunes as appropriate, select the device, and choose Check for Update rather than Restore.
Remove only a failed downloaded update
If an update file already appears in Settings > General > iPhone or iPad Storage, select it and choose Delete Update. Return to Software Update and download a fresh copy; do not delete unrelated apps or system data.
Escalate persistent verification failures
If multiple trusted networks and the computer route fail, save the exact alert, model, available storage, and software version, then contact Apple Support. Do not install unsigned firmware or third-party update tools.

If it does not work
- If the computer does not recognize the device, use a known-good data cable and USB port, unlock the device, and accept Trust when appropriate. If the alert names a different update stage, follow that exact Apple article instead of repeating the check-for-update procedure.
