Hello, I’m from India.

Just last year I saw on the news that someone who worked in a used cellphone store cloned SIM cards and sold them to people who were gonna use it to make thousands of dollars worth of phone calls and throw the SIM card away. Sure, that was very stupid of him since he was basically asking for trouble.

They showed it on the news channels but they didn’t provide the specifics about how he did it, i.e. whether he cloned it from an existing SIM or whether he captured/intercepted phone signals from nearby cellphone users on an active call.

I don’t know what version of SIM cards we have here but I’d assume we have the insecure old version cards here since we’re way behind in technology (contrary to what people claim).

Can anyone tell me if using the original SIM and the clone SIM at the same time, will one phone go through while the other will say call failed as mentioned by Don Juan or both phone calls be disconnected immediately? Thanks.

I want to clone a SIM phone so I can make calls from a Motorola (this old M works MUCH better for me and I use an old speaker in my car!) and stop constant switching out with my iPhone. Switching out is a PITA. I can imagine it could be a problem remembering if I have the other one turned off.

IMO Bluetooth sucks in the car!

When is the Ki created? Are blank/new SIM cards identical until used for the first time? Would it be possible to connect two new SIM cards to a handset (through some cable/adapter contraption) and have them end up activated and identical/clones of each other?

Donny Juan is full of s**t. The MagicSim downloads have trojans. I have exhausted all possible techniques/baud rates and used various readers. The said software won’t work with modern SIM cards period.

How about some other ways of getting a second (duplicate) SIM card? For example: are there any circumstances in the US that either AT&T or T-Mobile will provide you a second SIM card? Maybe for additional fee? How about if your original SIM card was damaged? Any other thoughts?

Regarding cloning of SIM Card:
Its a well known fact that the GSM architechture does NOT ALLOW for more than 1 SIM with the same data at any given time. The network will determine the physical location of the two SIMs, and see that they are in 2 different locations. Then it will normally shut down connection for them both. This is a built in countermeasure to thwart stealing air time from the network. The GSM in Europe (I can confirm Norway) can be a socalled twin subscription, giving 2 SIMs with same tel number (one phone with you, and one in your car) However, ONLY one can be used at at time, NOT both.
So this is totally waste of brains, energy, money.
If you want to monitor somebodys phone, there are 2 options: Software installing, like Neo-Call or Flexispy. You need to have the targets phone in your hand, either in standby (pincode unlocked) or know the pincode so you can unlock the phone (bring it to standby mode). After installing the software, you can secretly listen to the targets phonecalls (duplex) and read SMS. Totally covert. Not expensive.
Alternative 2: A GSM off air intercept system. I have been selling these since year 2000. Yes they are real, and work extremely well. But expensive, from 450 -650 K Euros. We are developing a totally new technology now. Hopefully ready coming summer at a price of 150 K Euros. Still not cheap, but better !

I too have the issue of not wanting to take my iPhone to work so would like to be able to use two sims.

I had a thought though and wondered if this would work:

Could I ring up Vodafone (my network) and say that my kid chewed on my SIM card when I left it on my table and its not working properly and could they send me out another one? I seem to remember doing this years ago when I accidently scratched my SIM and they were only too happy to send one.
My question is this:
Would Vodafone automatically cancel the old SIM card from working?
