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.

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.

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

Hermes cannot read some sim cards?

I have two sim cards, one for my relative and one for me. Both sim cards work on a Treo 650 I have, however, only my relative's sim card works on my 8525. The phone is unlocked and I can make calls and stuff on my relative's sim card. But when I put my sim card in the 8525, I get the invalid or missing sim card message. I have checked thoroughly that the sim card is inserted correctly.
This does not make sense. My sim card works fine as it works in the Treo 650.
Does that mean that the some sim cards are incompatible with the Hermes?

make sure its one of Cingular's new 64K SmartCards or whatever their called
their 3G Sim Cards
im not so sure if the old ones work?
they forced me to get a new one when i bought mine - even though it was already a 3g card...just an "old 3g Card" ? lol

well both of my sims are t-mobile sims, so maybe thats not it.

I have a 16k, 32k, and 64k simcard. All of them work on other phones Ive tried but the 32k sim does not work on the 8525 I have.
can someone verify this? It seems kinda weird that 32k sims do not work.

Give it some time

Few weeks ago I had to replace my SIM card, when I used the new one for the first time my 8525 didn´t recognized it, I tried then in other phones and worked fine with the others, so I call my tel co and had them to check my liene, they told that everything was OK and asked me to wait 24 hours!! I didn´t have to wait that long, it took about 5hrs and my 8525 started working as before.
BTW My SIM card is a 32K one.

seems like the problem was with my sim card, t-mobile replaced it and it works now....now to get tzones working *SIGH*

Network Not Found

So I have this Tmobile wing for 2 weeks and it worked fine until today.
I turned on the phone and the network couldn't be found.
I went outside and still nothing and I am using OpenTouch. can someone help me figure this out?

Have you tried a soft reset or a power cycle? If that doesn't work, consider taking out the sim card and reinserting it.

I had the same problem yesterday. I pulled out my sim card and put it in another phone to see if it was my sim and sure enough the other phone could not find a network. so i put in a new sim and called t-mobile and works fine now

Sim card issue

Hello guys
I'm having an issue when my x10 says there's no Sim card inside and the problem isn't with my Sim card since I tried in my old phone and it works. Even other Rogers Sim card don't work. Anyway I tried taking the battery out and after 3 attempt its working again. So, I want to know anyone else having the same problem and what's the solution?

I had the same issue but mine was a little different. My Xperia would not accept my rogers Sim ( 3 years old ) but it worked fine in all my other handsets.. it was the Sim card in my case and I was surprised to have it replaced free of charge.. also I found that some of the Sims are thinner than others so they would not have enough pressure to make a good contact. A quick fix from my friends Nokia was some clear tape on the back of his sim and it worked perfect.
Good luck!

TMobile's customer service department told me to bend the sim card very gently to ensure good contacts are made. Did this on first day and not had any problems since (famous last words... I'll be digging out the tape by tomorrow!)

My Sim card is like 5 year old anyway It's working now

All u guys with 5yr old simcards need to get rid of them! Those have like 28kb of storage on them, so their phone books are so, so limited!
I know! U use the phones memory, which is a whooooooole bunch! But if your phone ever crashed, all your contacts will be gone! U cannot always copy the entire list of contacts to the sim card, but with a newer 3G simcard, you can copy a lot more than your 5yr old sim card can hold.
These are free! Just walk into your provider's store and request a new simcard. U dont even have to show them what kind of phone u have (ahem!... those of us who are skimming with grandfathered data plans ). Just walk in and say "left my phone at work, but I need a simcard".

I think this thread will help you
as it does for me

I checked that thread, but I hadn't rooted my x10a yet. Going waiting until something extraordinary happens
Someday I will change my sim card lol

ZUK Z1 not working with AT&T or 3 UK

bought a replacement for my beloved ZUK Z1 because i had the infamous battery permenantly at 50% problem and the new one wont recognize any sim cards properly, i either get "error while searching for networks" or if it manages to find AT&T (it has a little sim card logo next to it when it does) it always says "cant connect to this network at the moment try again later" i get similar if not less fruitful results with my 3 sim card, it was sold as unlocked and it was unopened new when it arrived but i just cant get it to work
also the APN settings are all correct, ive done a factory restore twice, board tested it and re inserted the sim cards many times

Did you use any other ROMs? Try it since many ROMs have network problem. Try using ZUi.
