eSIM. My phone does not have a physical sim slot.

Both. Verizon service at one of my offices is trash, but our family unlimited plan is ideal for just about everywhere else. I can't beat the present pricing for the number of lines we have. My phone supports DSDS so I've got a physical Verizon sim as my primary and then a secondary esim that connects to T-Mo when needed.

Physical, because I couldn't get eSim to work on T-Mobile. Wasted tons of time trying to activate it.

Both, one physical SIM for data and one esim for calls. I'm actually using a sim from esim.me which turns an esim into a physical SIM so I still have my phone's esim free for when I buy a travel esim.

I use eSIM, because it's so much easier when traveling overseas to get a physical data SIM than it is to get an eSIM. Many countries' regs prohibit eSIM sales to non-residents, weirdly.

Maybe you can do both: physical USIM card, but with eSIM functions. So you can move your profile from one phone to another just by plug out and plug in, and install many profiles on one phone and switch between them. There are some products can do it, such as eSIM.me, esim.5ber.com or https://github.com/estkme-group .

Physical, because my telecom only supports eSIMs for smartwatches... Even if they offered it for mobile phones, I would prefer a physical SIM, so that I can swap it easily if I'm overseas

Both. I need two lines

eSim, that seemed to be the default for my provider/phone (Google Fi with Pixel). It works fine. The online activation seems to work okay, I've even moved to different Pixels without much hassle.

That aside overall I'm indifferent to using Sim or eSim.
