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

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 think the real issue is that US customers (at least) have been conditioned to think of a smart phone as something that costs between $0 and $300 due to the common use of contracts and subsidies. Even if a carrier offers a non-contract plan, they are often not that much better as far as price (with some exceptions like TMobile and some MVNOs), so they balk at paying $650-850 for a handset. That was one of the things…

The carriers should be required to tell the customer the total price, including the contract. Perhaps then the consumers would know what they are signing up to. And the contract length should be limited, given how volatile and fast moving the market is.

O2 have started doing this in the UK. It's actually what pushed me into going SIM free...

I'm slightly amazed at the awed coverage this is getting. As others have pointed out, multi-IMSI SIM cards are nothing new, though points to Apple for getting the network carriers on board and sharing keys. Getting a replacement SIM card is not a problem (certainly not in the UK). Most of the networks will happily post you out one for free and you can buy them for virtually no money in all phone shops, most supermark…

I'm on the other side completely, I'm a little awed at the lack of coverage, and consumer demand for this.

I don't think this is a technological thing, it's an industry structure thing. Why do we even need SIMs? Obviously we need some way of deciding which phone should ring wen a call goes through the either, but why does it need to be a piece of plastic.

A simple software replacement for a SIM would open a lot ip. You could buy a $10 plan when you're in a different country for a week. If one of those company offering cheap international call sims could just sell you a software sim that doesn't require you to switch over everything.

The ability to shop selectively using different providers for different calls would be a profound change to the ecosystem. It'd have a lot of knock on effects.

Apple are good at bulling through changes like this. This could be the start. iPad only is a little weak though. I hope their reliance on carrier subsidies to sell phones doesn't impact Apple's willingness to push on this.

Probably the most interesting thing from Apple today, in my opinion. The ability to buy short term plans from different providers effortlessly can turn my tablet into a much more versatile device, and increase competition and reduce long-term carrier lock-in. It's pretty sweet and if it can set a standard for phones then we'll see carriers become true utilities between which customers can switch easily if they get po…

In a truly competitive system there would be no need to ever conciously think about the carrier you were using. Your data would just be routed securely using the best means available and people would compete to be the best connection. Instead we have an absurd situation where carriers want to prevent customers using their product!

"Securely." You keep using that word. I do not think it means what you think it means.

Originally in the UK market contracts were the norm. Then Pay-As-You-Go opened the cellphone market up to teenagers, people on a limited budget, and people who used cellphones infrequently. That combined with the release of the Nokia 5150 and Nokia 3310 phones drove the market away from contracts. Plus in the UK the regulator is much more active in promoting competition (VNOs, Number Portability, tariff changes are a…

The first successful MVNO in the US came only 3 years after the first successful MVNO in the UK and mobile number portability was put into law in 2003 for both the US and the UK. The additional benefit is that because mobile numbers and wired numbers share the same area code base in the US, US number portability is basically universal. I don't see the basis based upon your listed criteria for saying that the FCC care…

Slightly unrelated but I find the idea of a mobile phone sharing an area code with landlines utterly bewildering. A phone, that by definition has no fixed abode, is now tied to a location and subject to long distance charges based on that location (As it was explained to me in Canada at least).

I used that word because I assumed that someone would complain that my suggestion is insecure. Of course the internet is entirely built around sending data publically across networks that you cannot trust. If you are building a new system to route data intelligently from the first hop it would make sense to include an encryption standard to make it less bad than the status quo. Having different classes of trusted networks just encourages a false sense of safety.

In a truly non-competitive system, we might be more conscious and more connected. Our internet connections might be routed using free high-speed publicly available internet and people would complain. Instead we have an absurd situation where a cartel of so-called "carriers" charge paying customers a toll for using the internet!

The end result of such a system would probably be to charge websites for last mile bandwidth instead of users. In a system with thousands of small ISPs that could actually work well to fund bandwidth expansion. Of course at that point everything would move to P2P and the system would break again.

Walk in any providers store and they will do it for you, free of charge. Takes 2 minutes. People who understand what a SIM like this does, will definitely understand how to replace SIM's. In my opinion anyways.

Most people don't even understand what a SIM is , let alone how to replace one. They probably can find their Settings app though.

I would argue that most people inserted the SIM in their phone themselfs. People switch carries all the time and most carries don't have stores, so who would put in the SIM if the customer doesn't?

If you buy the phone and SIM on the carries website, you don't get the SIM and phone in separate packages, so again who would insert the SIM if not the customer?

Changing carries from the settings app would most likely be more confusing. I think some people would be worried if the see the logo of a carrier other than their own in the settings menu.

The physical SIM card is secure, it stores your private keys for identifying you, and you can't extract those keys without damaging the SIM card. At least if the SIM cards are produced to spec. Can you make it equally secure in software, or can I borrow your phone and "easily" clone you ?

Actually this feature is not Apple exlusive.

I created a little project that allows remote usage of multiple SIM cards as a Software-SIM on MTK based Android phones. Forward the commands via TCP from a modified Baseband-firmware. This means you could e.g. have multiple SIM cards for your business trip without changing the card in your phone. Also malicious people could steal your SIM authentication if you use a vulnerable Android phone and use it:
