Two mobile phones with the same number!?
|
|
| Curious 2007-01-06, 10:33 pm |
| Hi!
Because I have a strong suspect that there is
some abuse with my mobile phone, I thank to
any person who can answer to the following questions:
1. Is it possible to "clone" a mobile phone knowing
it's number?
2. If yes, how difficult it is (1-easy to 5-very difficult)?
*I don't want to know how. Just if it is difficult.*
3. Is there any way to know if this is happenning?
For example some indication if both phones
are connected at the same time?
Thank you for any responses.

For the thousandth time (if not more), you can *NOT* have more than one
phone with the same number.

Make that CELLPHONE. You can have as many SKYPE phones online with the
same number as you want, simultaneously, anywhere on the planet. I carry
one, have one on my laptop and the one on the main computer runs with
Voxlib so I can access Skype from my cellphone when no wifi is
available...all running at once. Skype doesn't care because they're not
trying to sell you more numbers all the time, like cellular.
The reason you can't have 5 cellphones with the same number is because
cellular doesn't want you have them, not because it's technically
impossible....which it's not.

Actually, you just can't have more than one cellphone use the same number
SIMULTANEOUSLY; you can swap SIMs in GSM phones and you can, or at
least you could in the past, swap ESNs online with VZW (not sure about
other CDMA carriers).

Southwestern Bell Wireless (eventually Cingular), in the analog days,
used to allow multiple phones on the same number as an optional service-
(it was $20/month!). There were "catches" of course, due to the
technology- either phone could make outgoing calls (but when one was in
use, the other was "dead," and the first one to answer a ringing phone
took an incoming call, with no way to "transfer" it to the other phone.)
This service was primarily marketed to car phone owners- they could use
their full-powered, car-mounted phone when driving, and switch to their
handheld when out and about.
The switch to digital (which all but ended the car-mounted phone era) and
the creation of family plans (allowing cheaper access to multiple full-
featured lines) killed off this service (which was never very popular in
the first place!)
"Two phones with one number" is easy enough to simulate with a family
plan and call-forwarding that no real need for any technolgical
implementation of that as a service is necessary anyway. It doesn't
really make sense anyway- a telephone number, historically, belonged to a
"station" (i.e. a single location like a home or business.) It made
sense to have multiple telephones in one house or business work as one,
because you called that particular _place_ rather than a person. Why
would it even make sense for two cellphones to share a number? Unlike
the days of wired phones, with wireless you are calling a particular
_phone_ (well, presumably, the person carrying it!) rather than a fixed
location that person might happen to be at.
Or, to put it in the simple terms of supply and demand- if there was a
need for such a service, someone would offer it! ;-)

Analog and digital technologies are like night and day.
Even if there *was* a demand for digital cloning, I'm not sure the
technology supports it.

It wouldn't really have to- it could all just be "simulated" by the
carrier. Each phone or SIM "sharing" a virtual number could get a
distinct "real" number, and the carrier could just ring both of them when
an incoming call comes in and "connect" the call to the one that answers
first. For outgoing calls, the carrier could pass the "virtual" number's
caller ID info instead of the phone's real number.
This would simulate "two phones on one number" with very little change in
technology that I can see.
(Of course, I still don't see a need for it, particularly if the two
"extensions" are unable to call each other, as was the case with the old
analog system!)

It's not common to have two SIMcards (GSM/UMTS) with the same phone
number. But it is definitely possible. In those cases the holder of
the number has ordered a second SIM-card from the service provider.
It could, for example, be one card for a fixed mounted car phone and
one for a handheld/portable phone.
But copying a SIM card is only possible with a known PIN code and a
version 1 SIM card. Most SIMcards today are version 2 or 2+.

In some countries in Europe and Asia, you can get multiple GSM phones
with the same phone number, but this isn't available in the U.S. yet.
See
"http://asia.cnet.com/howto/askcnetasia/0,39051080,39375941-39002121q,00.htm"
It's not that it can't be done, it's that no U.S. carrier has wanted to
do it.
I also recall the days when you could have two AMPS phones on the same
number, for an extra charge. It was a lot easier to do on AMPS.

The technology supports "conference calling"....so, the technology supports
it. The phones DON'T all have the same ESN. So, when that phone number
(which isn't how cellular calls the phone, they call the ESN) is called,
the terminal rings all the phones on the PERMANENT CONFERENCE setup in
software. Whoever answers hears the conference...same as the OUTGOING
conference you can create on any cellphone, already!
This isn't rocket science. All that's necessary is to associate calls to
555-555-5555 with 6 ESNs in an outgoing conference call, all ringing at
once and set the conference to whichever ESNs answer the rings.
Geez, you'd think we'd have to reinvent the whole damned system! It's all
about SOFTWARE! Conference SOFTWARE!
Of course, we'll have to charge $30/month for the basic service plus SIX
TIMES airtime if everyone picks up.....(c;
There's absolutely no reason this outgoing conference call couldn't include
not just one company ESNs, but any landline/cellphone/satphone on the
planet!

(See my post about the outgoing permanent conference call).....
If you call your own number, the conference, any phone not already in use
rings, even though they all share a common landline phone number.
That's not rocket science, either....just software.....
(I want a royalty, you cellular bastards, when this is implemented! It was
my idea!)

I'm not saying you're wrong, but it's not a given that because a phone
can make two outgoing calls and bridge them (which is essentially what
we're talking about), more than one phone can have the same phone
number.
It SHOULD be possible, though. As you point out,
> The phones DON'T all have the same ESN.
The question is whether it's technically possible given the carriers'
current infrastructure.
I tend to believe that it is possible, but there isn't enough demand
to make it worth the carrier's time and money to change their software
over.
Otherwise, everyone would already be doing it.

Just its number? No. Number and ESN or IMEI? Still not likely, not
without VERY expensive equipment. Equipment that isn't easy to come by
nor easy to use.

On a scale of 1-5, I'd say about 30.

Doubt it.
Perhaps some alert would be sent to the carrier, but you'd likely not
know.
