Sim EMU

Did a search for SD cards and it came up with a SIM EMU post on this site. So going off topic, whats SIM EMU, what can it do for me, where can i get it (tried the link, that didn't work, tried a search and most of the sites aren'ti n english)
Seems like you can put more than one number on a card and switch without having to turn the phone off. Any further input, sounds like it could be good.

Will not work in UK, I found to my cost after destroying 2 sim cards. There is another twin sim holder that works with xda2 though, you just switch off and on when you wish to change sims.

Simemu is indeed a very good way to have up to eight numbers/accounts on one sim card. You select which one to use by pin number, so no more swapping cards over. It works fine in the XDA and just about any other unlocked phone.
The hard part is getting the needed info out of your original sim card. This is called the "Ki" and needs to be extracted. In the UK this has only been possible with all Orange and some O2 cards, never with Vodafone.
In the last year or so, some sims have appeared with a limit on the number of cycles they will run before self destructing, so attempting to extract the Ki can harm the card.
So it all depends on what networks you want to use and how old your sims are.

So can this be done with orange UK sims? My sims are about 4 years old, i have one thats much older, but i cancelled the contract on that so presumably disabled. Also have a couple of active PAYG sims.
I'd be interested to merge the new contract i have with an old number on the same card, would be useful.
I'm currently using everyphone divert, but it diverts all the time, even when my new [hone is off and old one is on. Annoying.
Other pain is it doesn't divert SMS, so i quite often miss them.

Yes, UK Orange cards of this age should be easy to extract the Ki from, payg or contract.
Also if you manage to get the Ki from the de-activated card, you should be able to get Orange to turn it back on as a payg or something.
Remember that only one number can be active at any one time, and you must never have the original sim turned on in another phone while using the copy of it in the multi sim.

Thanks for your replys kerr.
Have you done this yourself? Do you have any links of where i can find out information on how to effeectively try it and get it done?
All i'm looking for is that i have a sim with a great number. Its on orange no monthly tariff (i just pay for calls and just get a bill when i use it) Thats great for me as i hardly use it.
Then i got a new phone on contract (as it was way cheaper than upgrade). I've set up an everyphone divert from my old number to this one, but that annoys me as even with new one off and old one on, it still diverts. Shame.
So if i could get both numbers on the same sim that would be great, in principal! I get my number that i like, and i can quickly swith to new number to make calls (as its got free minutes). After the year contract is up i'll dump the new number anyway.
Whay can't you have the original sim on if its cloned?
Cheers

If you have the original sim switched on at the same time as the clone the system will know about it and you will probaly end up with a zapped sim courtesy of your provider.

there has to be a way around that :wink:

Yes, I made a card about 2 1/2 years ago which contains:-
1X O2 Anytime account
1X O2 Offpeak account
1X Genie PAYT
3X Orange PAYT with different off peak times chosen
1X Spanish PAYT
1X Greek PAYT
It has worked fine in every phone I have tried it in.
Whay can't you have the original sim on if its cloned?

You must not have them both on at the same time because they will both log onto the network and appear to be some kind of fraud attempt. (Somone else trying to use your account)
You really need to programme the card yourself rather than get it done because the last thing you would want is anyone else knowing your Ki.
To do this you would need a phoenix, a pic programmer and a blank silver card. All the software is free.

That sounds like one action packed card!
It would be useful just to have a couple of numbers on there, but you seem to be making the most of it!
Where can the exquipment be bought, borrowed? Is it readily available and cheap?
I see what you mean about someone else having the details. Could be a bit dodgy.
So this method is a bit like having a double sim car thing, but instead of having to turn the machine on and off, you can just put in a pin number.
With the XDA II tho, would the double sim card thing work if you turned flight mode off then on, would that switch the sims? Where can a double sim holder be got from

If you know anyone who is into Satellite Television, they will almost certainly have everything you need to do the job.
If you need to buy take a look at www.interesting-devices.com or www.maxking.co.uk. You could also look in the sat section on ebay.
If you go for a multi programmer like a Mastera, it would be all that is needed in one. See www.mcsat.co.uk.
When you change between numbers the phone does a soft reset, so I imagine flight mode on/off would have the same effect on a twin sim.

Using Supersim
Hello,
i read somewere that's impossible with new sim to read the Ki code of the sim because this code is read-protected.
Tring to read this you can destroy the sim.
It's correct?
I have an italian sim by vodafone!
Thanks for the reply.
Davide

Yes, that's right. Most of the newest SIM cards has a newer algorithm, so u cannot clone it. I don't know about your SIM card, maybe you have an old one. However, if U have 250 entry names in your phonebook, than it's probably new one and it could not be read, but do not be afraid to destroy it..., that will happen if U'l try to read it a few hours again and again....hope this helps!
Regards!
P.S.:
All backUp function support A3A8 COMP128V1 SIM Card only.
This SIM Card Back-UP device doesn't support newest SIM Card that uses COMP128V2 algorythm to code KI key.
Some GSM SIM Cards from 2001 (COMP128V1) are Scan-Limited. It has limited running scan 65536 times. If the scan is over 65536, the SIM Card will be locked. This SIM Card will not work any more.

Ki is stored in SIM card like CHV in respective file, but in Ki file's header all permission bytes are FF, e. g. it is impossible to read/write etc. with this file from external. From internal (COS) it is possible to read... the SIM do this when it calculate SRES+Kc

Any Dual Sim holder ?

Hi,
I'm wondering if there is a dual sim holder that fit in the kaiser.
I'd like one with no cut options. I've googled my question, but no answers...
Any ideas ?
Thanks for your help

I too would be extremely interested in this...

Still no ideas ???

dual sim
with no cut i think is impossebel
but wizh cut's
go to
http://www.simore.ch/fr/accessoires_pour_mobiles/HTC/P4550.html

certainly look impressive, but for tytn 2 you can only cut cards. have you tried one?

this looks awesome. anyone tested it yet?

or you can try to clone your card
other options is cloning the card. I did that couple years ago in my tmobile-usa card.

AFAIK this is only possible for networks and SIM cards using the COMP128 algorithm for authenticating the SI to the network. I don't know who still uses COMP128 but certainly in the UK no provider uses it on recent SIMs.
Highly unlikely to work with any USIM for the same reason - COMP128 is potentially insecure (obviously, if you can clone the SIM) so has been replaced with newer algorithms.
Just my 2p'th.

Yes you are right! I bought an old Tmobile card, before 2001 production, then I made clone and call tmobile to made a change to clonen-able tmobile card. I tried a couple of card before finally succesful. The new card have new algorithma and it is less likeable to be force to read for longer period of time than old one.

so getting back on track, has anyone used a dual card adapter in a TyTn II?
i assume you have a program to switch cards

I've been trying to find a Dual SIM Holder that can be used in the Kaiser without Cutting the SIM cards, but I don't think such a Dual Sim Holder exists, there is just too little space where the Kaiser holds its SIM
I really cannot cut my SIM as I have a work and personal SIM I want to use, and if i cut/loose the work one it will take em ages to get a replacement which is very bad...
Plus I suck at cutting SIMS lol, tried to cut my personal one and it killed it, had to get a replacement.

And, what about the cloning solution.
Is there any news ?

Sim Card

Hey does anyone know if there is anyway to make a copy of the sim card so i can have 2 cards with the same number?

Not that I am aware of. I believe the ID is pretty much unchangeable on a sim but these days almost anything is possible. I know that T-Mobile's system will not allow two sims with the same ID on the network at the same time. Not realy sure but I think there are legal issues with it as well. If it is illegal then better to just let it go.

It is possible to copy your SIM card, however you cannot have two SIMs with the same serial number registered on any network at one time. You must power off one phone then power on the other.
Beware though, SIM card cloners are very slow and carry a significant risk of ruining your existing SIM card in the process.
If you still want to do it, eBay is your friend.

I know they have that device at Tmobile stores. I had them use it for me to clone my existing sim card that was going bad.

the device they use at T-Mobile stores only copies your contacts. the actual SIM id is changed in their system so that your account, phone number, and SIM id all line up. once a SIM is bad the number is no longer used. and yes, Ebay is your friend.

Cant recieve calls sometimes

Hello
My HD2 does have full signal, but sometimes when people call me they get a phone is not available reply. I have tested this with a different radios, roms even on android and wp7. I've even tried switching to 3g even though im on a prepaid card. Please help!

You have a faulty SIM card, I would try getting another SIM card. If this does not help you may have issues with the SIM card tray in your device. If you have full signal then you do not have a reception or antennae issue and what I have mentioned is really the only next logical reason for your issue. ssIM cards just like anything else go bad from time to time even if they are not that old.

He's right, this is what I suspect too: a faulty SIM card.
Even it looks a bit odd, faulty SIM cards can be (more often than expected, and I mean it!) a p.i.t.a.
As a side note: I encountered a SIM card that was working perfectly with some common phones (nokia, zte or whatever), but not working at all with a Samy Exhibit 4g until SIM card replaced!

Its not a faulty sim card. Used 3 different sim cards including 1 from another carrier. Had the same problems

Currently I flashed the 2.12 radio and it seems to accept calls better sometimes but I still recieve the call error less frequently now.

Well seeing as you have tried different SIM cards then it very well may be a issue with your SIM card tray then. But I do suggest you flash the 2.15.50.14 radio and see if that helps, but I have a feeling you were already using it before you flashed the 2.12 radio.

slow internet speed in my phone

Yes. just in my phone and to only one sim card. When I put the sim in my friend's mobile the speed is normal.
possible reasons: Before some day I went to my village and the network reception there is very bad. I couldn't open any pages(pretty slow) .Now I am back to my previous place but the speed is same. I dont have 3G network here.
I have GT-S7562 rooted(dual sim). the problem is only with one sim card and only on my handset. I tried with new GPRS settings, rebooting, flight mode,network searching, interchanging simcards... not of any help. Its been 15 days since.
So what could have gone wrong? help

do u have a data limit?

What do you mean only one sim card? If you put another simcard (ex a friend's sim) does the phone work correctly?
If thats true then you should try getting a new sim card from your provider.

Keep in mind that your data speed has many limiting factors. (Ex. Service strength/ the cell phones actual capability /geographical location or region) but depending on your service provider, it's realitivaly cheap for a new SIM card in many cases. Last time I needed a new one it was $15...

Did you try another sim in YOUR (not a friend of yours) phone? It might be the phone's fault.

thank u all. As I said the problem seems only with that only sim.. other sim cards are working fine on my phone. Anyway I dumped that sim & got a new one.. All works good now. Don't know what was the problem with that SIM card. even Tech staffs couldn't solve it.
