Default Cloning Sim Cards??

Please Login to Remove!

I'm looking for help / advice. Thanking you ALL in advance.

I'm using a curve right now. I recently purchased another handset. I'll use it as a spare, or rotate it in and out when I get bored. You know, stupid stuff like that.

I've always been told that you CAN NOT have the same phone number for 2 SIM cards. But I just got done reading something about "SIM CLONING"...

(quoting from another forum post found in a Google Search) "I had two SIM cards with the same number, one for the pocket and the other one for the car. Problem I experienced is that the SIM you used last will remain active until you make a call through the other SIM."

Can anyone set me straight on this issue?

Can it be done yes, 100%

Why you do not want to:

1. The cloned card may produce errors to the network and get failed calls.
2. The cellular network uses electronic digital fingerprints that can tell if it is a different SIM. (Fraud Detection)
3. If the SIMS by any chance were both active at the same time your account is locked and you have some explaining to do.

Then you wouldn't need a card in it full time would you? I'd personally opt for swapping the card out on an "as needed" basis.

Honestly if you want to look into it I can PM you a few places to check it out. I updated my post while you were replying. I tried to make point 2 a little more informative.

It is very possible with advanced fraud detection on the network they would see the rogue card even if the 2nd phone was always powered down.

At one point if AT&T/Cingular/at&t caught you with a cloned SIM they would cancel your account charge you an ETF. If one carrier is doing it, expect the others to follow suit. Just another 175 reasons NOT to even try it.
