Getting the LG Watch Sport to work on T-Mobile

Many, including myself, were disappointed to see that Google partnered up with AT&T to be the exclusive carrier for the new LG Watch Sport. Many were unsure if it would work with T-Mobile but after some trial and error, I found out it does indeed work but there is a catch.

Sadly the LG Watch Sport will not work with T-Mobile’s  $5 “wearable” device plan, you will instead need to activate a normal voice line. This unfortunately does cost more depending on your current plan. You may use any Simple Choice or T-Mobile One plan.

Once you obtain a fresh SIM card activated with your new voice line, you simply need to power down the watch and insert the SIM. Once you power the watch back on, you will be greeted with a LTE signal.

I have tested the following and all worked without issue:

  • Voice Calls
  • SMS Messages
  • Data

Your mileage will vary depending on your area as not all T-Mobile bands are supported.

The reason this works is because T-Mobile only whitelists wearable devices they sell in their system for use on their “Wearable” plan, they just dont to a good job of letting people know that the only device this plan will work with is the Samsung Gear Smartwatch. They also do not whitelist devices upon request… I tried.

Now I just need to find how to use enough data to justify T-Mobile’s Simple Choice Unlimited Plan on a watch… this includes 14 GB of tethering.

    How are you getting your calls/texts forwarded to your watch if it has a full line active on it? I dont really want to have a number for my phone and then ANOTHER number for my watch? Thank you for posting this!

    • Sadly this method will ensure your watch has a 2nd phone number however the good news is you really dont need to use the watch phone number.

      After activating, open “Settings” > “Cellular” > “Advanced” and select “Call Forwarding” to accept inbound calls.
      If you are a T-Mobile Digits Tester, you may be able to get a 2nd SIM with the same number but I have not tested this.

    Quick question – Thinking about getting the LG Watch Sport and have been seeing that the Wearable plans do not work with it and only the Gear S3. If a phone plan is needed, and for clarification, can I get a new phone number with a tablet/device plan rather than an actual voice/cell plan?

    Keith, with the digits SIM are you able to make outgoing calls and text from your Primary line or does it use the number associated with the digits sim?

        Looks like the Beta is closed. I’m trying to get the details of how the digits SIM works. My hope is that they can somehow modify settings on their end in order to route calls/texts to an already active sim (non-tmo/current tmo)

        I’ve got it to somewhat work as I’ve used the digits app to route all my calls to my primary number to a Verizon number, but texts are not routed and outgoing calls are seen as the VZ number.

        • You are correct, there is no longer a BETA program for Digits, this article is a few weeks old and the Production DIGITS went live. You simply need to call T-Mobile Customer Service or visit a T-Mobile Store to get a duplicate SIM (I believe there is no monthly cost for this, just the price of the SIM starter kit).

          You can use Digits on a non T-Mobile Phone or WiFi Tablet by installing the T-Mobile Digits App. The network does not matter but all calls need to be done within the Digits Application, not the native Dialer or SMS for it to show it is coming from your number.
