Sometimes, the iPhone 16 Pro losing signal and internet connection can be due to something as minor as a network outage or Airplane Mode being accidentally enabled.

First, let’s verify network availability. To do this, here are the steps you need to follow:

1. Check if other devices (laptops, tablets, or phones) can connect to the same Wi-Fi or cellular network.

2. If other devices also have issues, the problem is likely with your internet service provider (ISP) or local cell tower.

3. Restart your router and modem, then try reconnecting your iPhone.

Lastly, check your phone’s Airplane mode. Follow the steps we wrote below:

Step 1: Swipe down from the top-right corner of your iPhone’s screen to open Control Center.

Step 2: Look for the Airplane Mode icon (a small airplane symbol).

Step 3: If it's enabled, tap it to turn it off and reconnect to your network.

These simple steps can quickly rule out external network problems and ensure that your iPhone 16 Pro isn’t disconnected due to a minor oversight.

A quick restart can clear minor software glitches, refresh network settings, and reestablish a stable connection between your iPhone and your Wi-Fi or cellular network.

To restart your iPhone 16 Pro, do the following:
