Why Does “Cellular Update Failed” Appear on iPhone?

The “Cellular Update Failed” error message on iPhone indicates the device was unable to install new carrier settings that were pushed out.

This is usually caused by poor connectivity during the update attempt. To fix it:

  • Retry updating carrier settings when on WiFi or better cellular signal.
  • Reset network settings to clear any residual failed updates.
  • Contact carrier support if it persists.

Does iOS Update Affect Cellular Signal?

In general, iOS updates do not directly affect your iPhone’s cellular signal strength or reception. The cellular modem hardware is rarely impacted.

However, issues like incompatible carrier settings, glitchy network settings, older SIM cards, etc can cause connectivity problems after an update. Troubleshoot the specific issue and cellular signal should restore.

Why Does My iPhone Say “No Service” After iOS Update?

An iPhone displaying just “No Service” or searching endlessly after updating iOS usually indicates a carrier settings incompatibility. The cellular radio doesn’t recognize the network.

Ensure carrier settings are up to date in this scenario. Reset network settings as well. Check for any iOS update bugs on Apple’s support site too.

How To Fix iPhone If Stuck in Recovery Mode During Update

If your iPhone enters recovery mode and gets stuck while installing an iOS update, force restart your iPhone by:

  • iPhone 8 or later: Press and release Volume Up, press and release Volume Down, then press and hold the Side button until you see the Apple logo.
  • iPhone 7 and earlier: Press and hold the Sleep/Wake and Volume Down buttons together until you see the Apple logo.

Then use iTunes or Finder to try restoring your iPhone to factory settings, or consult Apple support for next steps.

Key Takeaways

  • Check carrier settings, reset network settings, and toggle Airplane mode after an iOS update to fix cellular data issues.
  • “Cellular Update Failed” means carrier settings couldn’t install – retry updating when on WiFi.
  • Contact your cell provider if cellular data won’t work after trying standard troubleshooting.
  • Factory reset your iPhone as a last resort if all else fails.

Hopefully with some targeted troubleshooting, you can get your iPhone’s cellular data working properly again after an iOS update causes problems. Just take it step-by-step.
