SIM card VS e-SIM (lemmy.world)

I use GrapheneOS and love my privacy. However, I am not as knowledge in regards to simcards.

My family needed to get a new simcard while abroad and I was hesitant to get a new simcard and preferred to 'hitchhike' on a family members internet thearing so he could get a simcard instead of me.

It left me with the choice to:

Get a Sim card
Get an e-sim
Let a family member get a simcard and hitchhike from their internet. (Internet hotspot thearing)

My question: Was my worry in vain and I could actually get an e-sim/Sim or did I do it correctly, making someone else get a Sim and share the internet to me? :P

What I'm worried of, is that I'm currently outside EU and I don't want any weird hacking attempts towards me from the government. There are a lot of protests here, quite violent ones at times too, and I am aware that governments usually use stingrays or equivalent devices to identify or stalk people of interest.

Anything connected to the cellular network should be considered compromised, it doesn't matter if you're using a SIM from your own country or a local one if it goes through towers of the country you're visiting.

If you're so concerned, turn on airplane mode before leaving the network you trust and take a separate device for sharing internet over Wi-Fi or Bluetooth.

What do you mean by compromised? Monitorable? Traffic shaped? Both? How about E2E?

The cellular modems are vulnerable to attacks from towers, so if you're worried about things like stingrays, you should also worry about malware installed from cell towers.

Is it how StingRay work? My understanding is that it's about faking being a legit tower, not compromising a legitimate network.

It is not. But if OP is worried about state attackers, the network may be a problem too
