Title says it all. I know I won’t get the most out of an Apple Watch Series 3 using it with my Android phone, but I wonder if I can at least use the same number with an LTE Apple Watch Series 3? I am on a supported network, so I think this should be possible somehow, but how do I go about it?


Actually, what you want to do has already been done. It is possible, but not recommended. Below I will explain how you can get this to work, and then I’ll explain why it’s probably not worth doing.

Before you begin

Before you begin, you will need all of the following:

  • access to an iPhone 6 (or above) that is running iOS 11 and is unlocked (or, if locked, is on the same network as your Android phone)
  • an Apple Watch Series 3 with LTE
  • your Android phone (but it must be an Android phone that uses a microSIM)

Obviously, it goes without saying that you also need to be on a network that supports the Apple Watch Series 3 LTE models (which you already say you are).

What you need to do

Follow these steps to setup your Apple Watch Series 3 with LTE on the same mobile number as your Android phone. Note that these steps assume you have a brand new Apple Watch that has yet to be setup.

  1. Remove the microSIM from your Android phone
  2. Remove the microSIM from the iPhone you’re using
  3. Insert the microSIM from your Android phone into the iPhone
  4. Wait about 30 seconds or so for the iPhone to register your mobile connection
  5. Open the Watch app on the iPhone
  6. Press and hold the side button (not the Crown) of your Apple Watch until you see the Apple logo appear (Note: This may take a while, so be patient)
  7. Once it’s on, ensure you have the Apple Watch and iPhone close together
  8. On your iPhone, tap on Continue when you see a message about setting up an Apple Watch
  9. An animation will appear on your Apple Watch screen. Hold your iPhone over it so that the animation is centred within the viewfinder on your iPhone.
    1. Once it is paired, select whether you eat to wear the Apple Watch on your left or right wrist
    2. When the terms and conditions appear, tap on Agree
    3. Now you’ll be prompted to tap on Agree again
    4. Follow the rest of the prompts to sign in with your Apple ID, create a passcode, set up your Cellular (or Mobile) connection, etc.
    5. Eventually you will see an Apple Watch is Syncing message. Be patient while this process finishes, as it can take quite a while!
    6. Now remove the microSIM from the iPhone and re-insert it into your Android phone
    7. Wait about 30 seconds or so for your Android phone to register its mobile connection

Now you should be able to use your Apple Watch with the same number/network of your Android phone.

Why it’s not recommended

There are a number of reasons why using an LTE Apple Watch with Android is not recommended. In summary, the three main reasons not to do this are:

  • Your Apple Watch’s battery life will be really bad as it’ll be relying on it’s cellular connection the whole time, as opposed to using a paired connection with an iPhone most of the time
  • All your health and fitness data will remain on your Apple Watch and can’t be synced with any of your Android apps
  • Because of the above two reasons, your overall user experience will be poor!

Further reading

  • Thank you. This did work but as you so aptly predicted, my watch battery life really sucked. It was enough for me to decide I really love the watch, so have invested on an iPhone 6s and that just rocks with the watch. – Andy Nov 5 '17 at 22:23
