Same number on 2 different Sim cards |

Hi, I would like to know if anyone knows how I could clone my SIM to another SIM. The reason I need to do this is that I have Bluetooth capabilities in my BMW but for the phone to sync up, it needs to contain the Bluetooth Handsfree profile. My old T68i does and syncs up fine in my car. My P900, however, does not have the bluetooth handsfree profile (only has the headset profile) and does not sync with my car. Obviously I would love to just be able to use my P900 in my car as well as out.
So far my workaround has been to take the SIM out of my P900 and put it into the T68 when I get into the car and back to the P900 when I get out but this is getting tedious.
If somehow I could have a clone of my SIM I could just leave the T68i in the car and turn on that phone (and turn off the P900) when I am in the car and vice-versa when I get out of the car. Much easier than moving the SIM back and forth.
Any help is appreciated.
Thanks.

I don't think its possible to have the same number on 2 sim cards but let us know if you can.

I dont think is possible either!!! If you can remeber when you first signed up at you service provider they tell you to fill out a endless paper  . Then after you have returned the paper they pick up a credit card sized SIM-Card punch out holder. Well anyway while they have the card in there hand they are typing in a # located on the card then ask what would you like you # to be (if not listed on the paper.)
Well anyway to get to the point I am guessing that every SIM-Card has its own identity code. So in order for a SIM-Card to use a # given from the Service Provider the Identity # on the sim card has to be registered on the network. So for example if some how you can flash the # to another spare card , there still may be a reason why it would not work because even though the number from the service provider has been copied it wouldn't work either because the copied SIM-Card's Identity dosent match the one registered on the Service providers data base or because the # is already online to the network thus only promitting conflit on the network from the dupliclit...Just my guess.
Correct me if i am wrong please....
What you think?????

Remember that You proberly aren't allowed to clone Your card, depends on agreement and Your countrys laws.
A SIM-card is indentified by two things, the IMSI, which is public, and a KI-numer, which is secret.
To clone a SIM You need to create a new SIM-card with same IMSI and KI as on the one You got. For the phone/network, the both SIM's will be equal.
IMSI identifies the SIM/subscription, and the KI is used to assure that the SIM contains the right IMSI.
(Challenge/repsonse is sent by network).
Edit: Forgot to tell...
The only reason You're able to clone some SIM's is because operators are stingy. One of many algotithms for crypting the KI is cracked. Operators can easily change algorithm to a secure one, but algorithms aren't for free...
http://simemu.cjb.net/ is a software written for SIM-card creation/cloning.

Thanks for your input. I still don't know but I have read posts from people saying that some operators allow this for situations where people have a fixed car phone and mobile phone as well so I think that technically it must be possible. However, one would need to be able to read all the information on the SIM card to create a copy that would be indistinguishable. |

I believe this is what you're looking for:

Google up "SIM Cloning", there's a myriad sites and resources for this out there. Happy hunting!  |

You can definitely clone a SIM card. However, if you use both cards at the same time your provider will detect it and cancel your service on the spot, no notice. Just an immediate end to your phone usage. Then you can spend the next month or so arguing with them to reinstate your number, and maybe they actually will. In the mean time, carry lots of quarters for the pay phone! |
