Just curious.
I used eSim for a while when I first got a phone that supported eSim, because I wanted to make it harder for a thief to disable the phone tracking, but now my main phone is broken and I’m a bit annoyed at having to chat with customer support for half and hour to activate eSim on another device.
what’s eSim?
From my understanding, its a chip inside your phone that allows you to download Sim cards onto your phone. You could switch carriers without visiting a store or waiting days for the sim to arrive, just take minutes to an hour depending on which carrier you choose. Cool concept in my opinion, just not very mature at the moment.
I use both a physical sim (personal) and eSim (work) with a second eSim that I can enable and recharge when going outside of the EU so I don’t get huge roaming charges. When I’m at home it’s disabled so I only have the other two active
That hijacking risk applies to both. If you’re able to social engineer a telephone worker, they could move your account to a different SIM card completely.
My best advice, is to use Google voice, Google Fi, lockdown your number for SMS two factor. A Google account and lockdown mode, with physical security keys, is not going to get hijacked by anything less than a state actor.
Then your local phone, your local phone number, local SMS, none of that should be on your escalation path to authentication. Then you don’t care if somebody steals your sim.
Stares in American
This isn’t exclusively an American thing. I went to China and it’s extremely common to see SIM cards being hawked on the street and sold to tourists. They’re disposable and quite convenient. You buy them on the street, pop the SIM card in, get an activation text, and then you get data for a week before it stops working and you throw it away. They come with different data amounts and durations. But eSIMs do exist as well there, although it’s not nearly as convenient. You need to register your identity (surveillance purposes) and sign up for a regular phone contract. I haven’t seen any disposable eSIM plans there yet.
Phone models sold in China (even iphones) have had dual sim capabilities for a long time before eSims were a thing. I mean like 2 physical sim card slots in a phone. Adoption of eSims isn’t much of a necessity when the phone itself already can carry 2 sims by default.
On the other hand American phone models only ever had the one sim card slot. It’s a bit strange that eSims haven’t been as widely adopted.
I think that’s because of Chinese people’s travelling habits. Popular domestic travel destinations include Hainan for a tropical experience, Sichuan for pandas, Beijing for landmarks, Hong Kong for fake Britain, Macau for gambling, and Taiwan because it seems foreign enough without being actually too foreign (to Chinese people).
Hong Kong, Macau, and Taiwan require travel permits to enter, despite the Chinese government considering them “domestic”. They kinda straddle the line between actual domestic and international. Regardless, it’s not common for Chinese people to have phone plans that work in Hong Kong, Macau, or Taiwan, so they’ll buy the disposable SIM cards I talked about earlier. That’s why phones typically have two SIM slots.
Getting visas to travel internationally is a pain for Chinese people because they have to visit a consulate or embassy, apply, and then be subject to high scrutiny. After all, it seems everyone’s scared of Chinese spies nowadays. It’s also very expensive by Chinese standards compared to applying for a cheap HK/MO/TW travel permit. The People’s Republic of China passport is pretty weak compared to European or American passports. Chinese people can get visa-on-arrival or visa-free access in South Asian countries, Central Asia, or Africa, but these destinations are not popular with Chinese tourists.
