Do carrier unlock codes expire?

I received the message below from T-Mobile containing
the procedure to unlock my kid's cellphone.

I can email that procedure to the kid, who is away for a
few months, but the kid sometimes messes things up, and it
says that you can destroy the phone if you do it wrong.

If I wait, the kid will be back in a few months.

Do you know if these carrier unlock instructions expire?

Are you serious? Then you better cancel your message.
Not only never expires de unlock code, you make it posible to kidnap
it, due sending all the codes free into the whole world.

I do not understand.
I assumed that the code I received is ONLY for my phone.
So, what good would that unlock code be for someone with a different phone?

Unlock codes are specific to the phone. If one worked for all phones, do
you think people would go to such trouble to get one?

You are quite right: the unlock code is specific to the one handset in the
world with the IMEI that your phone bears. Moreover, the procedure the
email describes -- the "instructions for unlocking your LG device" -- are
specific to your particular model of LG phone. Motorolas, Nokias, etc.,
have unlock codes of different lengths, and unlock instructions of
different character.

Finally, as a general rule, unlock codes -- and unlock instructions -- are
good until used -- and beyond (one Motorola phone I had gotten unlock
instructions for -- and successfully unlocked -- mysteriously got itself
re-locked again when I put in a new carrier's SIM card -- fortunately, I
still had access to the old unlock instructions, applied them, and Presto!
the phone was unlocked once again :-) .

So don't lose that unlock instruction email :-) ! HTH. Cheers, -- tlvp

They are actually specific not only to the phone, but to the service
provider. So if you bought the phone from T-Mobile, it would have a different
code than the same phone bought from AT&T.

Some phones can be unlocked by buying the code from various vendors in
Eastern Europe. I have unlocked several Motorola phones that way.

Some phones require the code come from the service provider, who will only
provide them to current customers and may have other restrictions.

iPhones really need to be unlocked by Apple, who will only do it if the
service provider who bought it from them asks them to do it. Then a
magical unlock code is sent via iTunes to the registered owner of the phone.

There are many unlock hacks for iPhones, most of them don't work, or stop
working if you reboot the phone.

More particularly, an unlock code is specific to a given handset's IMEI.
The manufacturers leave it, in part, to the service providers to determine
to whom and under what circumstances to reveal the unlock code and
directions for its use. But "service provider" is not used so restrictively
as to mean cellular operators only, for, as you say,

Some phones can be unlocked by buying the code from various vendors in
Eastern Europe. I have unlocked several Motorola phones that way.

Mainly, it means Nokia or Motorola won't divulge unlock codes to you or me.
Or anyway, that's the impression I've always been under :-) .

Judy, relax. Yes, the unlock code will not expire but also it can not
be used or abused to kidnap anyone or anything.

The unlock code alone not indeed, but the IMEI code is a unique
identifier.
But who take care these days for personal securyty? One gives
everything away for a free lunch [1]. Apparently Judy is not aware of
the transparency of usenet.

I still have no idea what you are warning about. Please be specific about
what harm anyone can do to Judy by knowing both that unlock code and her
phone's IMEI number. Because some number is unique does not make it valuable
to anyone else who is seeking to do mischief. The Message-Id of your last
post was , which is unique,
and that knowledge plus $3.65 will buy me a Grande Latte at Starbucks.


How much does it cost me with out the knowledge coupon?

I think it is possible to track the phone's movements (provided
it's on) knowing the IMEI number. This works in two situations:
(1) you have a friend at the phone's cellular provider who has
access to cell phone tower data. However, if he's got
access to the tower data, he can probably do a phone-number-to-IMEI
lookup or customer-name-to-IMEI lookup just as easily.
and
(2) you are close enough to the phone to receive the signal directly,
with a "direction-finder" like device. Possibly it could
work better by pretending to be a cell phone tower and
getting the phone to respond to it. I don't know how common
these devices are, but I think law enforcement has them.

I think the unlock code is pretty useless, with or without the
IMEI number, unless you own the phone or plan to steal it.

Because some number is unique does not make it valuable
to anyone else who is seeking to do mischief.

A remotely readable unique number (e.g. cell phone IMEI numbers,
RFID tags (in, say, credit cards, clothes, etc.), toll tags, Bluetooth
MAC addresses, WiFi MAC addresses, etc. tend to be more abusable
in two ways: tracking/stalking someone, and spending their money.

The longer the range and the more related to money it is, the more
abusable it is. IMEI numbers are pretty long-range (I suspect
providers can do a network-wide international search, although the
radio signal probably reaches only a few nearby cell towers) for
tracking but don't seem to have much potential for financial abuse.
(At least on T-Mobile, the SIM card, not the IMEI, seems to provide
the billing info).

Credit cards with RFID chips may be readable for only a few feet,
making them not so good for location tracking, but the financial
abuse (and mistake) potential is enormous. I've witnessed two
people using Mobil SpeedPass accidentally pay for each other's gas,
then almost drive off before one of them noticed the problem (my
Toyota can't possibly hold 80 gallons of gas!).

Serial numbers are useful to people who steal phones. There is a worldwide
database of lost (greylist) and stolen (blacklist) GSM phones. It can
only be updated by a service provider and they can choose to use it
or ignore it.

Back in the final days of the last century, the UK cellular carriers
did not use the data base to encourage people to buy pay as you go SIMs
and put them in stolen phones. In those days they were planning IPOs, and
the valuation of the company was based upon the number of subscribers
(active SIMs) and not revenue.

Since GSM phones were new here (in Israel) and very expensive, I purchased
several used phones from a dealer in the UK who took them in trade, tested
them and sold them over the internet. When they arrived here, they
were blacklisted. Israel Orange used the blacklist.

To be honest, I'm not sure anyone cares though. There was a version of the
software to unlock the old Nokia handsets via a computer cable, and every time
you ran it, it incremented the phone's IEMI by one. I assume because there
were so many stolen phones that it was necessary. :-)

??? IMEI (not IEMI) isn't irretrievably burned into ROM? Anyway the last
digit of an IMEI is a check-digit -- what you get from a valid IMEI by
merely incrementing it by one is generally no longer a valid IMEI :-) .

In this case I did not have or use the software, by the time there were
enough GSM carriers here to matter, you could get unlocked cell phones
cheaper here than locked ones. Now no cell phones are sold here locked.

I assume what it did was to add one to the serial number part of the IMEI
and recompute the check digit. It worked and was quite popular.

A much nicer state of affairs than allowing SIM-locked phones, isn't it?
