Hey everybody, im new to this so please bare with me.

My girlfriend has a Nextel phone. Her X Boyfriend took her sim card out with all of the info on it. He then gave her a new sim card to put in her phone. (he says the other one was not good, which was BS).

Now everytime her and I send text messages to each other, I am POSSITIVE that he is recieving them as well. Im sure he is getting them online under whatever account he set up.

My GF and I set up an account on Nextel.com for her. It said that the SIM that we tried to register (the one that came with the phone, the "bad" one was already registered), but the new one in her phone let her register that one. We are able to see all of her texts online the way that we should. She has her own account and the X BF has no way of knowing this account info.

How did this bastard do this? Im a tech guy, but not when it comes to SIM cards. He is reading every text, but not on her account. Her phone and His phone both have MMS and all.

I called Nextel and they said that her account is in her name only and she gets the bill. They do work together and at the same company. The company does have others on "the companies nextel plan." BUT not her. She gets her own bill. The only way she is connected to the company with her phone is through direct connect. She is in the network or something like that she says.

Any help would be greatly appreciated. This has been messing things up for so many months now and I don't know what to do anymore.
 
1) Your GFs information on the SIM is limited to her contacts, that's it. Basically, only her phonebook info would be accessible up to the point when her old BF took the SIM out. Not much other than that lives on there.

2) When your GF got the new SIM, it would have registered itself to the NEXTEL network by the IMEI number in the phone because she would have gotten a new phone number with it. The SIM only gives the phone the ability to turn on and off for purposes of acitvating the phone for purposes other than 911 calls, storing phonebook contacts, and moving a user's phone number and contacts from one unit to another.

3) The "bastard" would not be able to intercept her text messages as they are stored on the NEXTEL network, not the SIM, and addressed by the IMEI number of the phone which is cross-referenced to her cell phone number in this format. [email protected]. The only way he could get her texts is if you're dumb enough to be sending to his cell phone number (her old one) instead of her new current one.

4) As for hacking the actual communications, iDEN is one of the most secure networks for cell phones. It utilizes strong encryption and is not able to be wiretapped without help from Motorola and NEXTEL. Even the Feds must seek this help. The calls and data are split up using a quasi-TDMA standard that divides the info into encrypted 15 millisecond bits. Depending on the vocoder in your unit it could be split into 3 or 6 divisions. The voice data is encrypted using a Motorola technology called VSELP. The data is encrypted using up to 128-bit encryption standards developed by the NSA.

IMHO, I think your GF better choose her friends better because they could be forwarding the messages she sends to them over to her old BF later. Loose lips sink ships. She's probably blabbing to them and in turn they're sticking it to her... especially if one of them is dating her old BF behind her back. Blackmail is not a NEXTEL problem, it's an operator problem which exists between the keypad and the user.

You'd know all of this by now if you would have searched the other posts in here and other cell phone forums because the question is always asked. RESPECT THE SEARCH BUTTON!!!
 
Thanks for your info. I do know that she is not forwarding these messages and I am sending it only to her phone.

You wrote "When your GF got the new SIM, it would have registered itself to the NEXTEL network by the IMEI number in the phone because she would have gotten a new phone number with it".

She never got a new phone number. It never changed. Is there a way that these messages we are sending back and forth could be going to his phone (with the old sim card) AND to her phone too?

It all started when "somehow" her entire SIM was scratched to hell. He took it and replaced it with all of the info/address book on the new SIM. So if the number never changed, what's that about?
 
Baseball bat is a good idea. It's my hands that need to make him feel the pain. I've tried for many months to do this the "proper" way, but he is leaving me no choice. :flamemad:
 
NEXTEL assigns phone numbers to IMEIs. They may have blacklisted the IMEI off of the old phone in order for her to keep the same number for her new phone. In any event, the network would not allow 2 phones to have the same phone number. Otherwise, the guys in here would have a field day by putting a phone in the den, one in the entertainment room, one in the garage... and they'd all ring at the same time. "Hey Chuck... Billy's on the line... says the i930 is dropping tomorrow at the Piggly Wiggly!"
