Basic Fixes:

  • Restart iPhone: Rebooting the iPhone effectively fixes common network issues. This helps reboot all device services and fixes any temporary glitches.
  • Enable and disable Airplane Mode: Airplane mode turns off all the radio signals on your iPhone. You can try out the Airplane mode to temporarily disconnect your iPhone from the network and take it offline. Now, reconnect it by disabling the Airplane mode.
  • Reinsert SIM: While the latest iPhone models have moved to e-SIM, millions still use a physical SIM. Pick your SIM ejector tool and remove it from your phone. Wait at least 30 seconds and insert it again to check for a network connection.
  • Check for software updates: Carriers usually bundle firmware updates with iOS builds. So, update iOS to the latest version to fix random network drops.
