The only big difference between the Apple Watch Series 3 and its older generation is support for cellular data. With the Series 3, you can start making and receiving phone calls and text messages without carrying your iPhone with you.
The only problem is that even with a built-in cellular modem, your Apple Watch Series 3 can always fail to send or receive text messages and calls over LTE. Several people have already experienced this problem. Some people left their phone at home and went on with the watch as a standalone device. Unfortunately, they were unable to answer incoming phone calls from it.
If you’re an owner of the new device, you may also experience an issue with LTE where you can’t send or receive text messages on your Apple Watch. This is a known issue within the community, but no official update to fix this problem yet.
While you wait for a quick patch from Apple, here are a few things you can do if cellular data and LTE isn’t working on your Apple Watch Series 3.
Text Messages not sending on LTE
For the most part, sending and receiving messages on LTE seems to be the most common problem. I went out for a walk earlier, attempted to send a text message to a friend, but it didn’t work. Not a single text was sent, and it hung there until I walked back home and my Apple Watch reconnects with the iPhone.
If this is what’s going with your Apple Watch Series 3, give this instruction a shot.
- Open the Settings app > Messages
- Tap on Send & Receive
- Log in with your Apple ID
- Select the phone number issued to your Apple Watch along with your email address
From there, try sending a text message to yourself or a contact of your choice. The steps above forces your Apple Watch to send iMessage using your email address (signed in earlier) and not just the phone number on your iPhone.
This is optional but recommended in case the instruction above didn’t help.
- Make sure your Apple Watch is connected to a cellular network. This can found by looking for four green dots in the Control Center.
- On your iPhone, open the Settings app > go to General > Reset > Reset Network Settings
- Unpair and re-pair the Apple Watch with your iPhone
Cellular Won’t Connect on Apple Watch Series 3
Text messaging isn’t the only issue. Some users were unable to connect the cellular data feature with their phone provider. AT&T and Verizon customers are complaining about this problem on their Apple Watch.
If you can’t make or receive calls with your Series 3, chances are you need to setup a cellular program first.
- Turn off Wi-Fi on your iPhone
- Open the Watch app
- Select My Watch > Cellular
- Tap Set Up Cellular
Follow the on-screen instructions to establish a connection with your carrier. After that, you should be able to use cellular data on your Apple Watch Series 3. If the same problem continues to occur on your watch, you can either wait for Apple to release an iOS update (and watchOS update) to fix this LTE connectivity issue or return the product.
