I have been waiting ages for the Galaxy Watch LTE. No it is out do I have ti switch to Telstra to get one to work or does optus support it?
From what I can gather yes you may have to switch. See if you can make any sense out of this thread as I'm still reading it myself.
At this stage, we're not selling the newest Samsung Galaxy watch nor are we offering support for the Samsung E-SIM.
We do offer support for Apple's eSIM.
