Welcome to the community!
We currently do not support LTE eSIM for smart watches. When you purchase a TPG mobile plan, we will send you a SIM card containing a single SIM in all sizes: Standard, Micro and Nano. Once you receive the SIM card, simply push out the SIM type you need.
There's no update on when the eSIM will be available on our Mobile plan, but once there's an update, it will be posted on our website and social media page.
Should you require further assistance, please let us know.
