That’s why when cellular service stop working on Apple Watch, the sole purpose of having the smartwatch seems to take a backseat. With these 11 tips at the disposal, you can troubleshoot the ill-functioning cellular connection on your Apple Watch right away!

Why is Cellular Not Working on Apple Watch Series 5, or 4? Tips to Fix the Issue

Solution #1. Get Cellular Service for Apple Watch

As not all carrier providers offer cellular service for Apple Watch, be sure you have an eligible cellular service plan. Also, make sure both the iPhone and Apple Watch use the same carrier. Besides, you need to be within your carrier’s network to use the cellular connection on the smartwatch. Head over to this page to check out which carriers in your country or region provide cellular service for Apple Watch.

Do note that pre-paid accounts and some older accounts may note be currently supported. It’s also worth noting that cellular roaming isn’t supported outside the carrier network coverage area.

Solution #2. Some Apps Might Not Update Without a Connection to Your iPhone

Are you trying to update some of your Apple Watch apps only to figure out that they aren’t being updated at all? Well, if you are staring at this scenario, let me tell you that some apps may not update without a connection to your iPhone. So, be sure you have ticked off this requirement.

Solution #3. Ensure That Your iPhone is Powered On

Not getting push notifications from third-party apps on your Apple Watch with cellular? Check out if the paired iPhone is powered on. The reason why I’m saying this is that the iOS device must be powered on and connected to Wi-Fi or cellular to enable the smartwatch to receive notifications.

Solution #4. Update watchOS

I have the gut feeling that a software bug could be at the heart of the problem. In this case, the software update is always the right way to go.

With watchOS 6 (compatible with Apple Watch Series 1 and later and iPhone 6s or later running iOS 13 or later), you can update software right from the Apple Watch.

Update watchOS Directly from Apple Watch

Ensure that your Apple Watch is connected to Wi-Fi. Open the Settings app on your watch → GeneralSoftware Update. Now, tap on Install if a software update is available and then go through the instructions to install the latest watchOS update.

Besides, you can manually check for the update and be able to install the update by heading into SettingsGeneralAbout. If an update is available, there will be an option to update the carrier settings. Don’t forget to download the carrier settings when you insert a new SIM card into your iPhone.

  • On iPhone X or 11, press and hold either the volume button and side button. Then, drag the power off slider to turn off the iPhone. Now, wait for 30 seconds, then after, press and hold the side button to turn on the device.
  • On iPhone 8/8 Plus or earlier, press and hold the sleep/wake button and then drag the power off slider to turn off the iPhone. Now, wait for 30 seconds to let the device shut down. After that, press and hold the sleep/wake button to turn on the device.
