How hard is it to scan and steal a cell phone number?

Alright, before people start shouting about how illegal that is, I am the victim and am trying to research how it could've happened.

I have had a cell phone for 3 years now, been real nice to have when driving back and forth across state 2 or 3 hr drives.

Recently, Sept's bill, I went from my normal 40-70 min of total usage to 356 min. Holy sh!t batman! That took my complete surprise. The bill claims I made almost 60 calls. I began to think about that, that is 2 calls a day average. But, the only 2 places I need to call on my cell phone are my parent's house and my girlfriend across state at college. Both long distance from my home phone, but not on my cell. Now, I am thinking, I go see my gf or she comes up here every weekend. That takes away 8 days of the 30 day month, pushing the call average to 2-3 calls a day. Now, I can specifically remember some busy days where I wasn't near my phone all day long. This is beginning to smell fishy to me more and more. But, I paid the bill for now and pretty much quit using my phone totally.

I get my next month's bill 3 days ago. 256 min !!!

I am already getting worried. I know I pretty much quit using my phone altogether and now I am getting hammered on my phone bill because of this. I have already called my cell phone company and am demanding a detailed bill of every single call coming and going from my phone for the last two months (my phone company got bought out and now doesn't give detailed billing standard, it costs you $3)

So, I am curious how easy or difficult it is to scan for a cell phone number and what I can do to prevent it from happening (again) at all. The phone was a 3 year old Audiovox analog only cell phone, so no digital encryption or anything like it.

Thanks.

what phone service do you have? some services let you sign up online and view your bill and phone numbers dialed.

Yeah.

I am going to go tomorrow and either cancel my service through them (out of contract anyways) or else at least get my number changed, despite how much of a pain in the ass that is to do. Gotta contact everyone you know and have them update speed dials, lil black books, or what-ever they use to keep track.

Thanks so far guys,

I'm a CSR for Cingular wireless, I can help you out a little. If it's an analog it's easy to clone. if it'a a digital phone ie, TDMA, CDMA it's almost impossible due to the phones ESN being aunthicated (SP) before the call will process, the esn is a unique serial number that is hard programed into the phone from the manufacturer and cannot be changed. I've never heard of a digital phone being cloned, and we have 22,000,000 customers, and if it's a GSM phone, it's said to be impossible as the data friom the phone is actually encrypted before it's sent from the handset.

Yeah

See....My old phone was a 3 yr old analog beast. My new phone, which I may be switching to Cingular Wireless this weekend, is a tri-mode phone.

What I need to know is what type of hardware is required to scan an analog signal and get the number to use?

This way it doesn't sound like I don't know what I am talking about when I get my detailed bill either today or tomorrow at the latest in the mail and call customer service to rip some heads.

Like Sean said if it is analog it is almost scary how easy it is to do with the right equipment.

See..........That is what I want to know, what type of equipment. When I get my detailed bill, and if it is full of wrongfully made calls like I think it will be, then I want to be able to call Cust. Service and say "Well, these aren't my calls and this phone is old. I did the research and found out that xxx type of scanner could've been one of many ways a thief could've stolen my number and began to use it."

OI know my company has a whole dept. just for investigating fraud cases, if you didn't make the call you will not have to pay for them, but like said with new digital phones, it's near impossible, I've never heard of a digital phone being cloned
