Updated : Getting the LG Watch Sport to work on T-Mobile


A few days months ago, I posted a set of instructions on how to get the LG Watch Sport to work on T-Mobile.

Once you enroll in the Beta, T-Mobile will send you a new SIM card in the mail. This normally arrives in 5-7 days. This SIM card can be used in any GSM phone and will act exactly like your normal SIM card. When you call your phone number – both phones will ring. In this case, you will simply use your LG Watch Sport as the 2nd phone.The Duplicate SIM will also receive SMS and even LTE data works.
