That's totally weird to me.

I don't want to say it from a position of superiority or anything, just different mobile culture, but in here, changing SIM cards is normal. It's what you do when you buy a new phone, because - as I said below - you get a SIM card separately, even when you buy it right with the operator with the contract.

But I guess it's a different culture



Different cultures for sure.

I've had 5 mobile phones...some candybar in the early 00's, a flip phone in the mid 00's, and iphone 3g, 4s, and now 6. I've never even /seen/ a sim card in person. It's a piece of tech that I shouldn't have to every even know exists. I just want my phone to work. I shouldn't have to play around with a microscopic piece of plastic and metal for that to happen.

I see it the opposite way. Every phone should have a part in it that is removable and replaceable and ensures that you can do whatever you want with your device. I was staggered when I found out that some US CDMA devices are literally unusable without the permission of the company you originally had service with.


Having a replaceable part is not the only way to ensure you can do whatever you want with your device! It is possible to ensure that with a universal SIM purely through software. That this isn't the current situation doesn't mean it isn't possible. I don't have to replace a tiny little piece of plastic in my computer to install Linux instead of Windows or to connect to wifi using Comcast instead of Qwest.


Hm. Interesting.

If you want to buy a new phone and keep your number.... what do you do?

Well I guess you can just ask in the store to move it to the new one, that's true. It's just... strange.


You don't ask, they hand you a phone and it just works.


Unless you want to buy an unlocked phone, etc. etc.


Why would you want to do that?

Give the provider the phone's public key fingerprint.

You're letting yourself be constrained by the very brokenness people are saying should be fixed.


Well in that case you have to have it tied with your name, so it will only work for contracts; and only about half of the people here are on contracts.


Works for pay as you go as well


I'd be willing to bet that most people wherever you're from also can't change their own SIM and have the store employees do it (which is how it worked when I bought a SIM card in both London and Seattle in the last two months).


Southeast Asia? That's one area where there appears to be little, if any, technophobia around SIM cards; and in some of them, on average each person has more than one mobile phone. Multi-SIM devices are also extremely common there.
