Has My Cell Number Been Cloned? 561

2bepissedoff asks: "According to my T-mobile phone bill, I have been receiving incoming calls from a 'NBR unavailable', since February, with talk time ranging from 1 minute to an hour. The strangest thing is, I have never received these calls (my phone doesn't ring and I haven't talked to the caller). I only started noticing them when my phone bill was charged over $40 more than my regular bill. Of course, I have a family plan (2 people only, 2 lines) and I talked to my partner. The answer: he too had not received any of these calls, especially over 300 minutes per month of them. We called up T-mobile twice and claim the possibility of phone cloning. Both representatives hung up on me, thinking I was trying to con them or something. Any advice to what this could be?"
I did a little investigation and I've noticed that some of the NBR minutes overlap with calls I actually make. For example:

'2/22 at 3:28 pm "NBR unavailable" 17mins usage.
2/22 at 3:44 pm "-(# I made)---" 3mins usage.

So if you add up the time 3:28pm + 17 mins = 3:45 pm. The time when I made my call was at 3:44 pm. This reoccurs several times. I still do not think this is enough evidence to convince T-mobile of Phone Cloning. So I am thinking of switching either my number or my service provider. "

    I still do not think this is enough evidence to convince T-mobile of Phone Cloning. So I am thinking of switching either my number or my service provider.

    You ask the question, "Has my cell number been cloned?" I ask the more pressing question... "Has your brain turned to mush?" DUH, if you're getting calls that you're not getting, then there's a problem.

    You say "Both representatives hung up on me, thinking I was trying to con them or something." I say, you need to adjust your message to give them the facts -- customer support reps are only human. If you ramble on with your life story, or rant and rave, or interject useless details, then you might get hung up on. But T-Mobile gave me good service when I had them (I only dropped them because they didn't have good service in the middle of nowhere, where I live). If you call and say "Here are the calls that I neither made nor received. Please remove them from my bill and block me from ever recieving calls from the associated numbers." I can't imagine they'd refuse.

    There's also the distinct possibility that the owner of the second line isn't being straight with you. I'm reminded of a poem I read on the bus [dart.org]:

    By the time you swear you're his,
    Shivering and sighing,
    And he vows his passion is
    Infinite, undying -
    Lady, make a note of this:
    One of you is lying.

    Wow... that was uncalled for. I had assumed by partner, he meant business partner. I will be taking on a business partner soon, and I would put him in a "family" plan if I had that type of service, because inter-calling would free in most cases. Even if it isn't his "business" partner, so what? Why do you have to use all the language? And of course, you assume the first person is a guy.

    Nowhere in the article does it say 2bepissedoff is a guy. Some women, especially in the tech world, hide their gender and use the word partner because they would rather have horny IT guys assume they are gay than a girl. Now ask yourself, why would "faggot" be the first thing to pop into your head? Why would such graphic images pop into your head? What is your subconscious trying to tell you? It's okay, stop hating yourself and admit what you are and what you like. You'll feel better in the end (pun intended.) People may make fun of you for it, but most of them are self hating fags, too.

    First off, your 17 minutes example is poor. The call could have ended at 3:44 and still be listed as 17 minutes, remember cell companies traditionally round you up to the nearest minute. If you had more then a possible 1 minute overlap example that would be different. Second, how well do you trust this "partner"? If they would presumably be on the hook for the overages if it was their fault, then they have motivation to lie same goes for if the calls are coming from someone they don't want you to know about...though I do not know what type of relationship you and this "partner" have.

    Next, either go to a B&M location and bitch to someone in person, have bills in hand, or send a letter/e-mail to customer service. The letter and/or e-mail are ignorable, but at least someone should attempt to read it. IF you actually show up at a location you are pretty much non-ignorable. Be sure to express anger, but do not do anything too stupid. IF worse comes to worse, threaten legal action against the location, the employees and T-mobile (always casts wide nets, threatening individuals works because they don't want to lose their money...loyalty to their business is probably minimal.

    So make sure to verify that neither you nor your partner received the calls...then go make a stink in person.

    I just don't understand why he (and it is a he, trust me) insists on using "partner" instead of just calling a spade and spade.

    Because he lives in a repressed society that doesn't allow him to call his partner his husband?

    It is quite appropriate that some people claim their morals come from words engraved in stone.

    Here's some advice: Don't take that shit.

    That's the best advice you'll get. You pay them to provide you with mobile phone service and in return they promise to provide that service. The onus is on them; if someone is illegally using your phone number and wracking up hundreds or thousands of dollars in calls you did not make, they have a vested interest in determining if this is true and putting a stop to it. The easiest way for them to do that is freeze yor account and issue you a new phone number. I have T-Mobile and managed to lose my phone in France; I called them immediately and they were able to freeze my account that instant, preventing anyone from making calls and I was able to get a replacement as soon as I got back.

    Try calling again -- keep calling until you get someone to listen. Try to cut right to the heart of the matter -- tell them you think someone is making calls using your number. A CSR should be able to pull up your current calling records and verify what you're terlling them easily enough.

    As an aside, why is it possible for calls from the same number to be going on simultaneously? Wouldn't there be something to prevent that, unless you were using a three-way calling option?

    They have the data to know when and where the calls were received based on the cell towers that the phone was received from.
    He mentioned that there is overlap, but only (in this example) by one minute. I would look for a more obvious instance, and on the same number, because this one could be explained by loose rounding to the next minute.


    Also, aren't bills with multiple numbers broken down by call to/from each phone? Mine is, I believe.

    Have you seen all the spy movies.

    Uh dude, I think you mean the evening news.

    Assume they are listening to your calls. This administration has a record of serial lying; they admit what they're caught at red-handed and say, "well, okay, we do A, but we would never do B, and the implication that we would is insulting and gives comfort to the enemy."

    Then a few months later we find out that at the time of the denial, they were doing A, B, C, and D (torture, kidnapping and illegal rendition to torture countries, domestic spying on Americans, leaking identities of CIA agents, other petty acts of revenge on perceived enemies, etc.).

    Don't reference fiction, man, the reality is more disturbing.

    The problem is that you're trying to supply a conclusive diagnosis to the T-mobile rep when you actually ahve no freakin' idea why those charges are appearing. Quit trying to offer them an explanation up front. That sounds like a con. Just give them the symptoms-- i.e. calls/charges on the bill that aren't yours-- and let them figure out what's happening.

    The total telecom costs are more competitive and come out less expensive in a system like ours (North America - mobile party pays for incoming and terminating calls; no landline to mobile termination fees).

    In the UK (and most other countries), the landline-to-mobile rate is fixed at a high price. The mobile companies have no strong incentive to lower their termination fees, because they're not charging "their" customers - it's the other schmucks (landline customers) who get the shaft (customers they want to steal away from landline!). Of course there could be some limited competition on the landline side to get the "lowest" mobile termination fees, but in the end the landline carriers still have to negotiate that with the mobile provider. How much would 1000 minutes cost from landline to mobile in the UK? £36.10 - £215.40, depending on the carrier and time-of-day? [bt.com]

    In the North American system, the entire minute bucket of incoming and outgoing minutes is negotiated between the mobile provider and their direct customer. Therefore, there is significant competition between carriers to provide the lowest total price. In other words, when you select a carrier here, you are negotiating the price on both sides. Over there, you are only negotiating the outgoing side of the equation (for the most part). How much would 1000 minutes (either direction) cost in the US? $40 (or free on nights/weekends)? [t-mobile.com]

    In the future, it seems like unlimited wireless is a distinct possibility (it already exists in my market!). In North America, that means that there will be no mobile-related charges whatsoever for incoming or outgoing. Do you think that foreign carriers will let go of mobile termination fees even if/when outgoing calls become free (unlimited)? In my case, I could pay $70/month and nobody would pay any per-minute fees to or from my phone!

  • What? What about when you are on the ground and happen to be standing in between 3 different towers, an equal distance from each? Wouldn't that be the same kind of situation you are talking about in an air plane?

    Because all the cells need to negotiate with each other to ensure that your phone is only logged in to one cell at a time? And if you're on a plane, not only can your mobile see a lot of cells (meaning that negotiation is expensive), but because you're moving fast, the system has to renegotiate very frequently as you move from cell to cell?

    Get names.
    Excellent advice. I'd like to add that this one bit of advice is the most powerful thing you can do. Every time you talk to customer service, the very first thing you do is get the name of the person you're talking to. The whole name, first and last. Make sure you understand it. If they mumble, ask them to repeat it until you understand it. It doesn't hurt to ask them to confirm the spelling if you have any doubt about it. I usually write it down while I'm talking, if it is convenient.

    Then, and only then, start discussing the reason that you called. It also helps to use their name while you're talking to them, to remind them that you really did keep track of the name.

    I find that this makes more difference in how good the customer service is than any other tactic you can try. Yes, a rep can give you a bogus name, but I haven't had a single one give me attitude or hang up on me since I started doing this. I also try to not be too much of an asshole; I tend to say things like "I know that it isn't your fault that I'm having this problem, but it is really pissing me off, and I want it fixed."

    As per the original post, I've found T-Mobile to give superb customer service, but I've been with them since forever, so they probably like me.

    Because whether the caller or the callee pays the extra cost for the mobile call is pretty much irrelevant and works out even in the end.

    Why do you have to pay extra for calling someone on their mobile phone instead of on their land line? Seems a bit of a rip off to me.

    As it stands, only one SIM number can ever be associated with a phone number.
    Actually, O2 Germany offers this as a service. (Yes, you actually get two accounts - one per SIM - which just share the phone number.)

    It woudl create a fault in the system which would prevent both yours and the clone SIM from working. This is actually one of the main reasons why Cellphones are not usable on Planes (even if it is prooven to be safe to the electronics).
    No, GSM can handle this quite well. In towns with a high base station density, it is also possible that multiple cells are visible.

    Dear Assface,

    I have a partner as well. We are of opposite sex, so your jealous, vindictive, increasingly irrelevant $(GOD) should not be offended (perish the thought).

    People often mistake us for being married (must be something to do with how we interact). We are, however, not married. We can't go around calling each other husband and wife, because that would be misleading, since we're not married. Hence, we refer to each other as, "partners."

    In other words, the term "partner" is not exlcusively used to refer to same-sex relationships. In fact, from the context of the article, "partner" could even refer to a business relationship, rather than a personal one.

    Like most religious/Republican extremists, you are likely incapable of apology, regardless of how strongly it is merited. Absent such, self-immolation will do nicely. *plonk*

    Whereas you do make valid points which are very possibly true, you dont say why my point is nonsense. It is perfectly possible that both of us are right!

    I told you, I worked for LogicaCMG, we provide manufacture Mobile Network equipment (Logica Mobile Networks). If you dont know who LogicaCMG is and the size of its involvement in Telecoms, well back in 2003, 75% of the worlds SMS all went through LogicaCMG Software. So now you know my experience, and expertise, let me continue.

    WHen a plane that is so high up crosses a densely populated city with a high cell density A cellphone will attempt to log onto many of those cells at the same time. Both the phone and the cells on the network will see almost equal "signal strengths" (distance between plane and ground is greater than distqance between cells, litttle bit of elementary geometry required here.. sorry I dont have a picture decribing the phemonenom). As such the netowrk does some form of conflict resolution which is communication and processor intensive.

    s the plane is flying at a high speed, its possibel the phone is connecting on and off to many cells in a short time (signals are weaker too), this causes a lot of strain on the network, sometimes causing it to go down temporarily as its automatically restarted.

    Multiply this by 100 or more phones on a single plane, and you can see how much of a strain this can be on the network.

    A network glitch like this looks bad to the operator, as customers on the ground are cut off their calls for a few seconds (there are some SLAs that operators have to publish here in regards to call disconnections)

    Our reasearch was actually contracted by Orange, and O2 in 1997 to helpfind ways to improve the ability to deal with mobiles on planes affecting cells on the ground.

    We have tested this phenomenon in our test labs many times to try and improve the systems.

    Together with better switching algoritms on the cells, and also the use of PICO trancievers located on the plane itself, we believe we have found some solutions for operators.

    But it is TRUE that the mobile networks were imforming the FAA and other airline bodies about this problem. Face it, they woudl me most happy for the extra income created when thier phones are used in the air, but currently their systems can break when they are.

    Before anyone informs me that cells were being used in one of the 9/11 planes. The plane was flying low over an area with much lower cell density.

    It's very annoying, but it seems like the only way to get problems resolved anymore is to act like a jerk.

    Problem is, the bad customer service epidemic is now conditioning people to pull the "jerk" card before they really need to.

    For example, my company prides itself in customer service, to the extent that we have never not replaced a broken product, even when well outside of our posted warranty period. Nonetheless, we get daily calls where people begin rudely insisting that they're going to get what they want... and before our reps have a chance to tell them that they will. I honestly don't blame the customers... it's just a sad statement about our service culture.

    To be honest, it looks like his partner probably had another "partner".. who called that line "number witheld", and was just fobbing him off, sayign that his phone may be cloned. That seems the most likely situation.

    I too have T-Mobile in the States. I had a similiar issue where as I had 2 phones on my plan. T-Mobile was nothing but entirely professional with me, able to cut the phone off while talking to them, and turn it back on 8 hours later for no fees, etc... (I actually did suspect my 'Partner') I have a feeling that you definitely did not talk to the CSR properly. Don't try to diagnose the problem for them, simply question the calls that you didn't make. I know from my T-Mobile bills, that each line is split out and detailed by default from T-Mobile, so you should know from looking at it which phone line is in question. If it is your partners' line, you might have to evaluate your trust in your partner and even the people around where your partner would store their phone. But in either case, T-Mobile has never hung up on me, so either you got the wrong Rep or you simply were not talking to them properly. GOOD LUCK !

    Either way, unless someone got a hold of your SIM card and copied it, I doubt you have been cloned. And generally in cases like that, the usage is much higher or there is more substance other than some calls to and from an unavailable number. I'm not saying the truth isn't stated here, but I find it very hard to believe two times you have been hung up on unless you have been VERY abusive. I think the best thing to do here is have someone from T-Mobile investigate the issue for you. Call in again and tell them in a nice, concise way that you are seeing calls you don't believe you have made and would like to see them investigate it. I wouldn't mention cloning as I highly doubt this is the reason you are seeing this.

    Your assumptions of the technological ommniscience of the phone companies is amusing, and baseless.

    First - there are legal barriers that allow you to strip a call of identifying headers. You can press a phone code to turn off your call id, and number forwarding, so that the recieving party cannot trace you. (in the u.s.) This was done so that victims of abuse could call home without fear of being traced. The phone company dosen't get that number either.

    Second - as any technologist could tell you, just because a system "should" work a certain way, dosen't mean that the programer who implemented it didn't hack together a fix overnight which worked, so it became a permanent part of the system.

    Third and Finally - Even though TV tells you that cell phone triangulation is a common practice, it's not. Triangulating on a cell phone call requires police, on foot, with three antennas, to find the right signal and take a measurement, from there they sit down with a map and work it out. This isn't built into the phone system, and its certainly not automatic. One reason for this is that one of the better ways to triangulate a signal is to measure the signal strength - if cell phone providers measured signal strength at all their towers consumer groups could gain access to those records durring the disclosure period of a civil suit to prove that large regions of their networks do not work sufficently.

    Remember, Technology /= Magic.

    It is both. Airline operators prohibit operating radio transmitting equipment on board an airplane in flight (FAA requires that any equipment that is going to be used be tested for safe operation on commercial flights), but even private pilots aren't allowed to use cell phones in the air due to FCC regulations.

    Adjacent cell towers coordinate frequencies in use, and do handoffs to the next cell as you move from one to the other. In an airplane, you are "adjacent" to many towers at once, even those that are so far apart that they can't coordinate and hand off. Even though YOUR call may end up working, you're probably disconnecting other calls over a wide area as you step on their frequency (and since you're about 5 miles away from the cell you're actually talking to that's directly below you, your signal is still about 50% as strong over a 5 mile radius around that tower).

  • Why do you have to pay extra for calling someone on their mobile phone instead of on their land line?
    you are the person who decided the matter was important enough not to wait until the person was back in touch with a landline, the callee on the other hand has little choice but to pick up if its someone they even vaugely recognise (or no caller id). so you should bear the cost of using mobile communication.

An authority is a person who can tell you more about something than you really care to know.
