dual sim or single? null

According to T-Mobile, this model supports eSIM, which is new technology not requiring physical SIM. That would make the 21 Ultra model effectively 2 SIM. eSIM can be used with T-mobile and physical SIM with other service. Apparently not every network supports eSIM function yet. T-mobile supposedly does. Looks like the sellers are not even aware of its existence. Nobody advertises it. There are not too many 2 SIM phones to choose from. With eSIM, there may be a lot more choices. If only sellers mentioned this compatibility. I found out only because T-mobile customer rep volunteered this info when I inquired about 2 SIM phones.
