Troubleshooting Steps for Error 1035

Let’s break down the troubleshooting steps systematically. Remember to test your phone’s cellular connectivity after each step to see if the error has been resolved. If one method doesn’t work, move on to the next.

Step 1: Basic Checks

Before attempting more complex solutions, let’s cover the foundational checks:

1. Restart Your iPhone: This is often the first and simplest solution for many software glitches. A restart clears temporary files and can often resolve minor connectivity issues. To restart, hold down either the volume button and the side button (on newer iPhones) or the side button until the power off slider appears. Then, slide to power off, wait a few seconds, and power it back on.
2. Toggle Airplane Mode: Enable Airplane Mode in the Control Center (swipe down from the top-right corner on newer iPhones, or up from the bottom on older models) or through Settings > Airplane Mode. Wait about 15-20 seconds, then disable it. This can force your iPhone to re-establish a connection with the cellular network.
3. Check for Carrier Outages: Visit your carrier’s website or use an outage checker website (such as DownDetector) to check if there are any reported service disruptions in your area. If there’s a widespread outage, you might have to wait until it’s resolved by your carrier.
4. Ensure Your SIM Card is Properly Seated: Turn off your iPhone. Use a SIM ejector tool or a straightened paperclip to eject the SIM tray. Remove the SIM card, inspect it for any damage or dirt, and then carefully reinsert it, ensuring it is properly seated. Push the SIM tray back in fully and firmly.
5. Check SIM Card Compatibility: If the SIM card is very old, or if you recently switched to a different plan, confirm that your SIM card is compatible with your iPhone and your carrier’s current network requirements.

Step 2: Network Settings and Configurations

If the basic checks don’t yield a solution, delve into network settings:

1. Check for Carrier Settings Update: Sometimes, carriers release updated settings to optimize network connectivity. Go to Settings > General > About. If a carrier settings update is available, you’ll be prompted to install it. Follow the on-screen instructions.
2. Select Network Manually (if available): Go to Settings > Cellular > Network Selection. Disable the Automatic toggle and your iPhone will search for available networks. If a network corresponding to your carrier is available, try manually selecting it. After a short period, try toggling back to Automatic selection.
3. Reset Network Settings: This step will remove all saved Wi-Fi passwords, VPN configurations, and cellular settings. Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. You will need to reconnect to your Wi-Fi networks after this reset.

Step 3: iOS Software Updates

Keeping your iOS software up-to-date is crucial for overall stability and bug fixes. An outdated iOS version might contribute to connectivity issues.

1. Check for iOS Updates: Go to Settings > General > Software Update. If an update is available, download and install it. Ensure your device is charged and connected to Wi-Fi before starting the update.

Step 4: Check for Software Conflicts & Corruptions

Sometimes a third-party application or a corrupt system file might be causing conflict with the Mobilephone service

1. Safe Mode Check: Reboot your phone into Safe Mode. The procedure varies depending on your iPhone model. Typically this involves power-cycling the device, and then holding down the volume down button as it reboots. In safe mode only the default iOS apps will function, if the error is resolved, a third party app might be the cause of the issue. You can go through installed apps to see if there are any recently installed or updated ones, and uninstall them one by one to find the problematic app.
2. Restore from Backup: If the error continues, try restoring your phone from a previous backup. Go to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings. Set up the phone again and then when prompted, restore from a backup. If the error is still present the issue is most likely with the current iOS software configuration or a hardware issue.
3. Clean install of iOS: The last software solution is to perform a clean install of iOS using your computer. Connect your phone to the computer and put it into DFU mode. The procedure is different on different devices, so be sure to find the right instructions for your iPhone. Then using the iTunes or Finder application on your computer install the latest iOS software on your device. If the problem is caused by a software conflict, a clean install should solve the problem.

Step 5: Contact Your Carrier

If none of the previous steps have resolved the com.apple.mobilephone Error 1035, there might be an issue specific to your account or SIM card. Here are some points to cover with your carrier:

1. Check Your Account Status: Ensure your account is active and that there are no issues, like overdue payments, that could restrict cellular services.
2. Verify SIM Card Activation: Confirm that your SIM card is activated and linked to your account correctly.
3. Request a New SIM Card: If your SIM card is old or potentially damaged, requesting a replacement might be necessary.
4. Inquire About Network Issues: Specifically, ask if there are any known issues affecting your area that might be contributing to the error.

Step 6: Hardware Inspection

In rare instances, the error could indicate a hardware problem within your iPhone. If you’ve exhausted all software-related troubleshooting steps, a hardware inspection might be required. Note that if the phone is under warranty you may void the warranty if you try to inspect it yourself.

1. Check for Physical Damage: Thoroughly inspect your phone for any physical damage, such as dents, cracks, or water exposure, which might impact the cellular components.
2. Check for Water Damage Indicators: Examine the SIM card tray slot and the charging port for any signs of water damage such as a reddish discoloration on the indicators.
3. Contact Apple Support or an Authorized Service Provider: If you suspect a hardware issue, schedule an appointment with an Apple Store or an authorized service provider. They can diagnose the issue and offer repair options.

Additional Tips

• Keep Your Device Clean: Dust and debris can accumulate in the SIM card slot, so keep it clean. Use compressed air to gently blow away dust from the SIM tray.
• Avoid Unauthorized Repairs: When dealing with hardware issues, it’s best to stick with authorized service providers to ensure proper repair and avoid further damage.
• Be Patient: Troubleshooting such errors can sometimes take time and patience. Don’t get discouraged if the first solution doesn’t work, and try going methodically through all the steps.

Prevention

While you cannot completely prevent all errors, adopting some best practices can minimize the chances of future issues:

• Regularly update your iOS software to keep it secure and performant.
• Keep the SIM card slot clean.
• Avoid exposing the phone to extreme temperatures or moisture.
• Make regular backups of your phone to facilitate restoration if needed.
