back to article iPad forces operators to shave their SIMs

O2, Orange and DoCoMo are all apparently stocking up on micro SIMs suitable for Apple's iPad, though taking a sharp knife to an existing SIM is always an option. Quite why Apple decided to use the third form factor for the iPad's 3G module isn't clear, but anyone planning to stuff an existing SIM into an iPad will need to be …

maybe

Because if you cut down your SIM to put it into the ipad you are discouraged from moving because it will rattle around in just about every other device.

Makes sense

No phone features, so what's the use in a name/number pair?

name/e-mail with optional number on the other hand DOES make sense on the iPad.

Nothing wrong with a standard address book, but having a sim that can only store phone numbers in a device that can't ring people would be odd when there's alternatives available.

Did you read the article?

Especially the part where it says the application that allows you to store name/e-mail and numbers together runs on either micro or mini-SIM.

A mini SIM is already too easy to lose. The micro-SIM is going to be ridiculous. Don't understand the design choice at all - unless Apple want the slot to be so small you can't see it?

in which world?

I imagine there are much easier ways of sharing email addresses. iTunes does it just fine for example. That and I can't see a reason for wanting to transfer anything. For any "smart" device, using a SIM card to transfer numbers is completely superfluous.

I'm only slightly amazed that Apple still allow a removable SIM...

Prevent SIM sharing?

Surely this is just to prevent users from swapping SIM with unlimited data plan back and forth between phone and iPad when required.

It forces the user to have additional SIM and plan, which helps the network operator revenues.

no.

What you;re basically saying is that a carrier can't tell the difference between a phone and a tablet if you swap a SIM. That is WRONG. In fact, they can actually tell the difference between your smartphone and the machine tethered to it using that same connection...

Basically, any access to the web included in the packet header information about the device making the request. Somewhere in there, the carrier will EASILY be able to discern between iPad and some random other device, if nothing more than to look at the MAC address of the device making IP requests.

erm...

Aren't mac addresses part of an Ethernet frame which is stripped from the packet at whatever routing level when the packet leaves the local subnet? and are specific to the NIC if it is being used at all? Does blueetooth use mac addresses? or a USB interface?

missed by a mile

he is saying you cant swap them round because of the size difference.

it would be like trying to swap a standard sim now with a old credit card sized one

However...

This would make it appear "ok" in the eyes of a consumer. If they straight up denied access based on the IMEI connecting to the network then the customer would see that as "greedy". However if there was a different SIM size then they would actually be forced to buy an additional data plan- but they wouldn't think that it was unjustified as having to have seperate plans.

Also they network could know what device you have by checking the IMEI number when the device conncects to the network basestation.

On a side note; we can't have these phones with NOSIM in the UK- that would be horrible (but I think thats CDMA?)

Apple - Just another example of consumer milking

WTF?

It's size

The iPad is so small it nee....

Hold on that's not right is it. The iPad is HUGE cf+ modern phones, so it could easily take the cc sized model, although they're basically obsolete nowadays.

The "normal" SIM size doesn't seem excessive, but I can't recall if they found space for an SD card either?

Simple

"None of which explains why Apple would choose an unexploited standard for the iPad."

Because they can.

Because they'll then be able to patent small sims.

Because they've defined it as the new standard.

Take your pick.

Makes it impossible to swap SIMs

Yuck.

If the iPad used a normal SIM, you could take the SIM out of your phone and use it for a bit of iPad web surfing. For very occasional 3G usage, that saves the cost of two subscriptions or the hassle of a second PAYG SIM.

But no... once you cut down your SIM to fit the iPad you won't be able to get it back in your phone.

Nah..

Piece of cake, just keep the snapped off bit, put a length of sticky tape over the back of the hole and you have a handy dandy Apple defeating SIM carrier that you can use by just sticking your micro sim in.

Any bets?

How soon do you think it will be before someone starts selling some sort of adapter sleeve thingy that will allow a microSIM to fit properly in a full sized SIM slot?

This is MY idea and if used I must be credited to me, so there! Though a check would be nice too ...

Best of both worlds?

"Perhaps Apple is offering operators an opportunity to differentiate between computers and phones on their networks - computers, and dongles, could use Micro SIMs (sold with broadband data-only tariffs) while phones will use existing SIMs with unlimited data, and those of us in possession of a sharp knife can enjoy the best of both worlds."

Probably not, unless Micro => Mini adapters become a wide spread option. They might already be, but I haven't heard of them (no demand?).

Personally, I would think there would be more sense to having the computers using the credit card format - especially if the GSM module is integrated into the computer. While it may be a non-starter for USB dongles, it could work out well to have the USB allow the card to have just the edge slipped in, and the rest of the card integrating a GSM antenna... But if everyone could connect, the network would have to upgraded to support all that traffic at once, wouldn't it?

And THAT won't happen anytime soon... Now, off to patent the idea of the credit card format integrating its own GSM antenna... :)

Isnt it obvious?

You cant take your sim out of your iphone and stick it in your ipad, if you want 3g on your ipad and you already have an iphone then you need a second contract.

The problem with drinking the Apple Kool-aid is not only do they charge you for it, they also charge you for the cup and someone to pour it for you

Maybe

but then releasing the iphone first kind of makes the ipad obsolete in the main - why would you carry around a huge tablet that has no more capability than your Jesus phone.

I reckon people with an iphone are more likely to by a full fledged netbook with keyboard than this device.

Sounds like a cunning lock in...

Once you have your iPad with its micro SIMM you won't be able to use another mobile device, even if your iPad goes wrong, your SIMM won't fit any of your other phones!

Quick, someone invent an adapter! Although it's my idea and you'll need to licence it.

@Makes sense

And storing them on the sim of a device that already has Gb of storage makes sense why?

So you can quickly transfer contact details to your other iPad by swapping the sims out?

Dual sim holders

There are plenty of dual SIM holders which already accept micro SIMs. These require you to cut the plastic of your existing SIM to make it a micro.

Make an adapter then!

You know, like an SD sized adapter that MicroSD cards fit into - just with SIM cards? So you can swap it from your phone to your iPad and back with ease.

could it be a glimpse of the future?

Maybe - just maybe - this will be the size format of the SIM required for the next generation of iPhone - setting a president with this device enables providers to get stocks in and then a smaller sim could equal a smaller 4th Gen iPhone or, its to make more room for - i dont know, say, a longer life battery?

There are SIM adaptors available

...that let you use micro SIM cards in normal and mini SIM devices, and they are cheap bits of plastic usually as part of a dual SIM solution. Sounds like a 3rd party opportunity rather than a real 'problem'.

Still, it would be remiss to pass on a chance to whinge about Apple's new creation ;-)

But was it Apple's decision?

One possibility is that the choice of a micro-SIM wasn't Apple's decision as such, but a condition imposed by AT&T - who will be offering cheap unlimited data plans for iPad users.

Presumably Apple's reluctance to allow tethering and VoIP applications is driven by the need not to annoy the network operators ...

Way to go Apple.

"Apple has been saying the Micro SIM will also support a more-comprehensive phone book as well as greater security."

In other words, the tech is there and compatible with the SIM today, but NO ONE uses it, so Apple, in their ability to F* with the market as they do, are essentially mandating support for these better security standards and better phone book model and enforcing operators to move to more secure and more user customizable systems if they want to make millions hocking Apple's to-die-for products.

Nice.

Yeah, I thought that looked suspicious.

All that extra functionality just from cutting the plastic edges off? Thanks for the explanation, the world got rather surreal there for a moment and I was wondering which things that I own would benefit from having a fews bits filed off.

The answer's got to be, as others have suggested, to prevent data plan "sharing" between devices. I can't think of any other reason why a larger device would need a smaller SIM apart from sheer bloody-mindedness on the part of its makers.

Re-using a micro-SIM in a phone

Easy. Well, easyish.

Take a look at the illustration in the article. Many PAYG SIMs come as a 'credit card' and you snap the SIM out. Take that 'credit card' and cut a normal SIM sized piece out of it. Cut a hole the size of a micro-SIM in that.

Tada! A convenient micro to normal size wrapper / adapter. It's even easier if cutting a standard SIM down to size - the bit cut off is the wrapper / adapter. Not something you want to use if regularly swapping from one thing to another but it works.

Paris : Who knows about filling holes.

"But no... once you cut down your SIM to fit the iPad you won't be able to get it back in your phone."

Yes you will- just need a plastic bit the size of the larger SIM with a mini-SIM-sized hole in it. Same principle as the plastic bit to play mini CDs in a normal CD player. Simples.

You're not Apple engineers are you?

There are lot's of reasons for this sort of thing ...

"I had one on my desk when we mocked it up"

"I designed for the larger SIM but needed some extra space"

"We did the drawings in imperial units but the fab house used metric"

"I lost the spec sheet for the other ones but had a spec sheet for this one"

"Steve told me to do it"

"We had samples of both types but lost the larger ones - oh wait, there they are"

etc etc - trust me on this, I've seen them all over the years.

Paves the way for micro SIM in next iPhone

To prevent people from swapping in SIMs with unlimited data plans? Seems like a very unlikely explanation to me - if a full-size SIM can be cut down to a micro SIM, then presumably some enterprising company will quickly make a little 'bracket' that will hold a micro SIM and make it fit a full-size SIM socket again.

I think it's because Apple wants to use a micro SIM in the next iPhone, where the extra space made available will be a real advantage. Putting a micro SIM slot in the iPad now ensures there's a ready supply on the market before they introduce the next iPhone.

Apple has a history of adopting tech...

People said the same thing when Apple introduced USB (developed by intel) on the original iMac's, which were PPC machines. Apple adopt things because they are a good idea, before the iMac used USB and demanded that all peripherals use USB connections there were no USB peripherals. As soon as the iMac was launched with the only method of giving it additional functionality being USB, there was suddenly a flood of peripherals. About 6 months later the PC world suddenly decided it might be good to actually use these things and build some kind of driver in windows to support these plug and play devices. The same thing happened with Firewire (IEEE1394), which was actually a Sony technology to start with (they branded it i.Link), Macs originally used firewire for storage and DV Camera connections, on PC's you had to buy a card to get the connectivity.

Apple as a technology company likes things to be neat and elegant, if they can make something smaller they will, expect the next iPhone to also use the MicroSIM, as it will provide more space for the battery or other components in that form factor.

Firewire was from Apple...

Apple started working on the basic technology in 1986 (yes - 1986). However, both Sony and Texas Instruments contributed to the final standard.

Oh mighty Apple, why MicroSIM?

That's easy to answer: one can unlock a mobile phone using a TurboSIM card, which is the size of a MiniSIM card. And there's no TurboSIM for MicroSIMs as far as I know.

So baseband processor is locked tighter, no TurboSIM exists for MicroSIMs and there's a win for the operator.

Adapters are hardly rocket science

We were playing around with these at work a couple of months ago. It took us literally seconds to figure out that a SIM card sized frame made of solid core equipment wire was all you need to hold the SIM in the right place on a normal phone.

tethering?

What's wrong with tethering your iPad to your phone (maybe even to your iPhone). If you're out of range of WiFi, you're out, so you must have your phone with you anyway. Don't need a 3G iPad.

...like that bloody annoying little blob of plastic on Apple USB connectors tat stops you using it on everything else. I suppose if you're rich enough to afford this rubbish, you're rich enough to buy bespoke USB leads and tiddly SIM cards. I dunno.
