iPhone 5 nano-sim card | Phone/Device Issues and Features | Consumer forum

It doesn't matter. Apple patented the nano-sim and has made it the defacto standard for the nextgen sims.

Maybe that explains the lack ofnew phones with speakout with the standard sims.

You can't port a SO number to Rogers Sim and keep SO's plan. Rogers Sim will only work with Rogers' plan.

Also, I don't think SO's sim card will work on any LTE phone at all. So far I have tried HTC One X LTE, Samsung Galaxy S2 LTE, and S3. Even if it is cut properly to work on an Iphone 4, the data plan won't work on any of those LTE phone, and in HTC One X case, won't even work at all. Not even just voice.

I would have to say the 4S would work fine on SO if you just want to us app that does not requires a full data plan, but any LTE capable phone (which Iphone5 most certainly will be) are going to be fairly wasteful or not work at all.

That is nice to know -some- LTE phone works perfectly. All the one I have tried does not work properly. Either low download speed, or not recognizing the carrier at all.

Well the iPhone 5 has been announced today and it is confirmed that is using the nano sim.

you CAN NOT convert a sim or micro sim to a nano sim. a nano sim is exactly the size of the chip and it is also 15% thinner. so a trimed micro sim will not work. unless there is a way to make the micro sim thinner. then speakout will work with the new iPhone 5.

Hi there,
Just a few thoughts on this discussion:
I personally believe that the information that it is not possible to modify a standard (ie SO) or micro SIM to nano SIM is not correct. The nano SIM is downward compatible so my suspicion is, that the technology is still the same while only the form factor has changed.
Yesterday I took an old SIM card and first cut the corners straight to the borders of the metal contacts. I then took a nail file and took about 15% (guestimated) of the thickness of – without touching the chip and still some way to go.
So I don't see a reason (without having tested it yet for obvious reasons) why I shouldn't be able to do this with a working SO SIM.
Here you find a fairly good picture that could be a template: http://www.engadget.com/photos.....is-here-0/
So I will order the iPhone 5 tomorrow and will probably buy a new SO SIM to try before cutting and filing my "real" one.
As soon as I have results, I will post them here.

ps. Using a SO (micro) SIM since February in different phones and I am very pleased with the network! I don't need 4G/LTE btw, just need data on the go for emails, maps and a bit of browsing, so I am fine with 3G in Toronto etc.

would the LTE on the 5 becomes an issue ? As other users reported mixed result for LTE enabled phones.

Hi,
Here is the information about the different SIM card formats.

Wiki Subscriber Identity Module (SIM)

Here are the different SIM dimensions.

As you can see in the table, the embedded-SIM chip is the same for all the card formats. Here is the actual SIM chip structure (the GOLD part you see on the card)

GOLD contact

As you can see, the SIM chip international standard (PATENT design) has not change. You have 6 contact points in the shape of brackets ( ). The extra gold metal contact surrounding the bracket shape contacts are buffers possibly grounds. That is why the newer SIM you see are smaller, it is removed in the later SIM packaging.

To SUM it up, yes the Speakout SIM would work if you can trim the excessive parts surrounding the embedded-chip without damaging it. This should not be an issue. I am sure there will be cutters available to trim the excess. The most difficult part is to trim 0.11 mm thinner. If you know how thin 1mm is 0.11mm is almost nothing.

I don't know how good Apple manufacturer can be but I am sure there may be some error room to stuff 0.11mm difference into the iPhone 5. I am sure other manufacturers when they start designing phone to accept nano-sim format, there will be wiggle room. If not, shaving 0.11mm should not be a tough task with a fine grinding stone and slow speed Dremel.

I don't see any benefit gains from slicing a few millimetres except to gain the control where it can only be used on one type of phone. If Apple's intention was to give them more real estate area for other usage on the phone, they could just embedded the SIM IMEI right into the phone and just lock that portion out, just like CDMA days.

I hope Apple fail with their tactic to differentiate their phones with the masses. Unfortunately, there are too many sheep lining up to purchase. And the volume controls the standard even though there is no benefits from the new design.

I for one still think the original standard SIM is more than sufficient to use on all phone design. I believe if they are going to make it smaller than get rid of it completely. There is no real need for it now. The SIM card main intention was to allow the portability of a unique identifier. The secondary feature, they gave a piddly amount of storage space that can hold some telephone numbers, but no one really uses the telephone storage feature anymore. And to have a chip to store a string or even a 1024bit encryption key is overkill.

There has to be a better solution.
