We have been examining how upgrading to a new iOS has brought different issues to iPhone, iPad and iTouch users, such as iPhone won't make calls after iOS 10 update. In this post, we will be looking at how iOS 13 upgrade affects user interaction as regards applications and games, and provide solutions where they exists. One of the reasons for app troubles during any upgrade is the fact that most applications haven’t been updated to meet up with the changes in the operating system of iOS devices. Despite this, there are steps you can follow to minimize the effects of iOS 11 or iOS 12 upgrade on your device.

iPhone Can’t Make Calls after Update to iOS 13

A lot of changes can occur once an update is done. Updates can change your devices settings, and prevent you from making or receiving calls. Whatever the problem is, a little troubleshooting can be the solution. Try the following:

  1. Check iPhone settings: It’s possible the new iOS upgrade altered the settings of your device. Check that airplane mode is not turned on; check if your “Do not Disturb” settings is off; check if the number you’re dialing is not blocked.
  2. Remove and insert SIM card: Sometimes, the SIM card can be the problem. Simply removing and reinserting can solve the issue.
  3. Reset your Network settings: To do this, simply tap “Settings”, navigate to “General”, then tap “Reset” and tap “Reset Network Settings”. If this doesn’t walk, try changing location to see if the local network is the issue.

iPhone Can’t Send and Receive Text after Update

This error is similar to the “Can’t make calls” issue above. To fix this, try any of the following:

  1. Perform a hard reset: A hard reset can make the problem go away. Simply hold the “Home” and “Sleep/Wake” button for a few seconds till the phone reboots (when you see the Apple logo). If this works, fine. If not, try the next step.
  2. Reset your network settings: Perform a network reset as highlighted in the “Can’t make calls” section.
  3. Turn off VoLTE: Voice over LTE is relatively new technology to some carriers. This means it might not be reliable in all locations just yet, and this unreliability causes problems such as text issues. To turn it off, Settings > Cellular > LTE > Data Only or Off > Reboot iPhone

App Crash or Won’t Load

As mentioned above, third-party app developers don’t have the luxury of knowing what a new iOS will entail, so they are always playing catch-up when a new iOS is released. Before going ahead to delete that app crashing for the umpteenth time, you might want to try the following:

  • Check Apps Store to see if any new update for that particular app has been rolled out. As a precaution as well, try reading the reviews left by other users to see if there are additional problems with the new update.
  • If there isn’t any new update, rove the app and reinstall the application. This has also been proven to work for different users having issues with different applications.
  • If the above doesn’t work, you might have to contact the developers, it’s likely you aren’t the only one having such issues.

iMessage or Facetime Won’t Activate

There are basically four types of errors you’ll get as regards activating your iMessage and Facetime. They are:

  • Waiting for activation
  • Activation unsuccessful
  • An error occurred during activation
  • Could not sign in, please check your network connection

To solve any of the above, perform the following:

  1. Check your device settings: Make sure you are connected to data, either via Wi-Fi or cellular data. Also be aware that activation on iPhone requires SMS messaging. Make sure you have enough airtime credit as most carriers charge for this SMS. Another setting that can affect your activation is time and date. Ensure you have the right date and time by Settings > General > Date and Time.
  2. Restart Facetime and iMessage: Sometimes, simply restarting both apps can do the trick. To do this, Settings > Messages/Facetime > toggle off iMessage/Facetime. After this, restart your device and toggle on Facetime and iMessage following the same steps to turn them off.

It usually takes about 24 hours before both Facetime and iMessage get activated. If after this time, you still have issues, contact your network carrier to ensure you can send and receive messages or contact Apple support.

Touch ID Not Working in App Store

Another major headache for some Apple device users has been their inability to use the Touch Id for verification in the Apple App store, but can use the Touch Id to log into the phone. To fix this error, try this fix:

  1. Go to the “Settings” app.
  2. Find and tap the “Touch ID and Passcode”.
  3. Enter your 6-digit passcode.
  4. Turn off Touch Id for iTunes and App Store.
  5. Restart your device by doing a hard reset.
  6. Go back to “Settings” and turn on Touch Id for iTunes and App Store
