Yes,

I went to AT&T store, asked for a QR code for esim. They transferred my number on the spot. Added it easily by following prompts under cellular "add a cellular plan". You can even name the line for all apps (primary, secondary, personal, etc).

The AT&T Folks said it wouldn't work with eSim. it works fine.
They also said the data would be limited. I'm on FirstNet which kinda is cheating since it priorities traffic, but I pulled over 100mb/s UPLOAD.
They also said it wouldn't work with Verizon - CDMA. They were right, for only about 10 minutes.

My old Verizon Sim took a bit of work. The phone wouldn't recognize it. I tried power cycle. Turned OFF the esim line from AT&T, then re-inserted. Not sure if power cycle, or multiple tries to re-insert but after about 3 of each it worked.

Now I have BOTH AT&T and Verizon - very strange to see two superimposed rows of signal strength bars. It appears to say 5Ge or LTE. Unsure if it's related to which data connection Im using or signal strength.

Either way, I can receive calls and use data on both - and it switches to whichever is better.

HAPPY with my purchase.

As to your question about service bars - I live in an area with horribly spotty coverage for most carriers.

I'm not saying eSim and nano sim improve the signal (bars looked better in some areas, definitely not lower), but I didn't experience a single call drop or lull in service on the commute home (which is normally a daily occurrence).

Tl:DR - No diminution in signal strength or coverage running dual sim.

Can you expound on this!?
that’s not true. You designate in setting which line you want your data to run though and you can choose to initiate a call from either line you’d like. But there is not an option to have the phone dynamically choose based on signal strength. The best you can do is assign certain contacts to certain line but again I believe that’s only outgoing calls and messages.

Really?

"Allow Cellular Data Switching" (option under cellular data)
Turning this feature on will allow your phone to use cellular data from BOTH lines depending on coverage and availability.

Its only for switching during phone calls.

Change your cellular data number
One number at a time can use cellular data. To change which number uses cellular data, follow these steps:

  1. Go to Settings.
  2. Tap either Cellular or Mobile Data.
  3. Tap Cellular Data.
  4. Tap the number you want to use cellular data.
If you turn on Allow Cellular Data Switching, then while you're on a voice call on your voice-only number, that number automatically switches to use voice and data.* This lets you use both voice and data while on the call.
If you turn off Allow Cellular Data Switching and you're active on a voice number that isn't your designated cellular-data number, then cellular data won't work while you're on the call.
To turn on Allow Cellular Data Switching, follow these steps:
  1. Go to Settings.
  2. Tap either Cellular or Mobile Data.
  3. Tap Cellular Data.
  4. Turn on Allow Cellular Data Switching.
* Your data line switches automatically for the duration of your call. This cellular-data switching will not work if you are currently using Data Roaming. Check with your carrier for availability and to find out if additional fees apply.

Under “Cellular Data” you toggle to allow data from either line, depending on coverage.....calls go to what number rings....

I know, I was trying to give him some leeway to express his logic. Which he did.
