Having trouble with Wi-Fi disconnects, crashing apps, or a missing SIM card on your iPhone X? You’re not alone. Whether you just updated iOS or restored from iCloud, many users run into strange connection problems with their devices. The good news? Most of these issues can be fixed at home with the right troubleshooting steps.
Below are four common iPhone X connection problems and how to solve each one.
Problem #1: iPhone X Keeps Disconnecting from Wi-Fi
Issue: Your iPhone X won’t stay connected to Wi-Fi and forgets networks, even after you’ve manually joined them.
Fixes to try:
- Force Restart Your iPhone X
- Press and quickly release Volume Up.
- Press and quickly release Volume Down.
- Hold the Side button until the Apple logo appears.
- Reset Network Settings
- Go to Settings > General > Reset > Reset Network Settings.
- Enter your passcode and confirm.
- Reset All Settings
- Go to Settings > General > Reset > Reset All Settings.
- This won’t erase your data, but will reset all system preferences.
- Factory Reset (as a last resort)
- Go to Settings > General > Reset > Erase All Content and Settings.
- Set up your phone as new (do not restore from backup right away).
Problem #2: Snapchat App Crashes on Login After Upgrade
Issue: You upgraded to an iPhone X, and now Snapchat crashes immediately after logging in—even after updates and reinstalls.
Fix: Since you’ve already updated Snapchat and tried reinstalling it, this may be a compatibility issue or a rare bug.
- Contact Snapchat Support:
- Open the Snapchat app (if it opens), tap your profile > Settings > Help > Contact Us.
- Or visit support.snapchat.com directly to report the issue.
This issue is app-specific, and Snapchat’s support team may be able to offer a fix faster than waiting for another app update.
Problem #3: Facebook App Keeps Crashing
Issue: Facebook crashes repeatedly—even on a brand-new iPhone X.
Fixes to try:
- Delete the app from iCloud backup:
- Long press the Facebook icon > Delete App.
- Then go to the App Store, search for Facebook, and download it fresh, not from iCloud restore.
This ensures you’re not pulling in a corrupted backup copy of the app.
Problem #4: iPhone X Won’t Detect SIM Card
Issue: iPhone X suddenly says “No SIM” or “Insert SIM” even though a valid SIM is inserted.
Fixes to try:
- Restart your iPhone X
- Same process: press Volume Up, Volume Down, then hold Side button.
- Factory Reset
- Go to Settings > General > Reset > Erase All Content and Settings.
- After wiping, set up your phone as new and insert the SIM during setup.
If the SIM still isn’t recognized, it could be a hardware issue with the SIM tray or reader.
- Contact Apple Support or visit a service center for repair or replacement.
