activating data automatically from esim in case of lost

Apple to expand repair options with support for used genuine parts - Apple

This does not apply to an iPhone 11. Even if it did, you need special training and special tools.

can u help me with the information that if it is possible to somehow dive into my iPhone without password?

That is not possible.

I see no point in continuing this discussion. so I will not answer any additional questions.

Find My is best used for lost devices, and is not particularly useful with stolen devices.

I’m inferring this isn’t theoretical, and your iPhone was lost or stolen, so best assume it’s not coming back, follow the steps in the linked article below, and replace it.

Find My can work when the iPhone is ostensibly powered down, as the baseband can stay active at short ranges, and that will relay whenever within range of other Apple devices. No cellular connection (on the lost or stolen device) is required.

More generally, what to do: If your iPhone or iPad was stolen - Apple Support

I’d usually disable all plans and blacklist; SIM or eSIM.

That as those can be trusted telephone numbers for other activities.

As for remote switching of active cellular connections, or even whether the device can gain any cellular access, no.

You do understand that iPhone thieves will power off the phone or place it in a small Faraday bag that will not allow the phone to either send or receive a signal, correct?

In other words, if a phone is stolen, it is gone.

No, It won’t, If the phone is the following…. Lost or Stolen. It won’t activate. I recommend calling your provider to block or blacklist the phone to prevent any charges on the line monthly or yearly.

Blacklist: Blacklist is like when you block your phone to prevent anyone from using your phone.

The thief will not power on the phone and leave it on for more than a minute or two. Do you what a Farady bag is?

The eSIM will not do what you are asking.

If the phone is stolen, you will never get it back.

even a minute could leave me the last location isnt it? and for how long it will be switched off? at any point in the time, they must turn it on for a longer time, right?

Any competent thief is going to go to some effort to try to thwart Find My.

Whether that is Find My on any of the multiple eSIMs that might be present, or via the SIMs, or short-range comms.

Your iPhone is not coming back.

It may well be disassembled and parts sold by now.

Or powered down and offline and en route to another country for eventual resale.

Yes, you can invent ever more hopeful scenarios, and I do wish you well with the eventual recovery of this device.

No, it won't. You would have to manually change a setting in the iPhone for this to occur....and you don't have the phone.

Anyway, a thief will keep the phone powered off most of the time or more likely just keep it in a Faraday bag.

The chances that you will even seen the phone online using Find My are just about zero. Good luck though, miracles sometimes happen.
