This isn't exactly true. In some dual-SIM phones that have recently  
entered the market...


Those would no longer be _after market_ products.

It requires two GSM modems inside Neo. That closes this issue.

Oh, yes it is!

Hello.

It was already said that two SIMs working simultaneously would require

This is obviously is not a case of GTA02.
Planning feature list for GTA(03|04) is quite a waste of time until
GTA02 will be released.
  
AFAIK gsm modem is about 1/3 of phone production costs. IMHO basic neo 
would never have two modems as it's still very rare to use dual-sim and 
it would generate unwanted neo's price rise.

So, let's concentrate on GTA02, perhaps?

I'm sorry for being keen, but I've waiting GTA02 for a quite lot of
time by now, so I panic when seeing any proposal of hardware
modifications that could delay (if accepted) phone release.

The dual SIM products you can buy after market, take two SIM cards, and
provide a way for to switch between them, either by rebooting the phone,
or via a SIM services menu.

For a future Neo, it would be helpful to have two or more SIM slots, and a
means to switch between them in software, each switch would probably
involve rebooting the GSM modem, so that it would 'see' the new SIM card
and log into a different network.

This feature would be useful while traveling, especially in Europe where
there are lots of small countries, and some people commute between them on
a daily basis.

It could also be used for lowering call costs. For example, when the user
makes an outgoing call, the software could consult some rules to see which
SIM would be cheapest to use. It might even be possible to quickly switch
to it before starting the call. The SIMs not in use would be automatically
diverted to the one in use, so that incoming calls would still get
through.

Here is a description what dual SIM means and why: 
http://en.wikipedia.org/wiki/Dual_SIM

I knew that and this is an excerpt from article you metioned:

> Normal GSM phones contain a single transceiver 
; dual-SIM phones must have 
dual transceivers,


and according to what kkr wrote

> dual-SIM slot in their products. And both SIMs are active at the same 
time!


I suspend what I wrote - if both SIMs should be active at the same time 
(above) it reqiures two modems (aka transceivers)...

Any chance to have a dual-SIM slot on futures products?

[kkr]

I remembered a discussion about how to use more than one SIM card in the
neo.

Until recently, I've only seen some kind of hack about it. For example,
in the battery or in a SIM card adapter (or by cloning a sim card =
illegal).

http://www.dualsim.de/
http://ucables.com/ref/SIM-CLONE



It seems that some manufacturers (Samsung and Verzio) have integrated a
dual-SIM slot in their products. And both SIMs are active at the same
time!

http://www.verzioworld.com/as/pressroom.html
http://www.mobilegazette.com/samsung-duos-d880-07x10x08.htm

The Samsung DuoS gets around this by having two SIM slots in the back, 
and both SIMs are active at the same time.
...
At the moment, the Samsung DuoS / D880 has only been confirmed for
release in Russia later this month. It's a relatively expensive device 
at 18,000 rubles (around £350 or €510) before tax. Expect to have to 
pay the full price without any discount, because no carrier will want 
to subsidise a handset that another carrier will use and locking the 
device to a single network would be pointless.




I'll have use of it (professional/private number with two differents
operators) and imagine that will be wished too by people which travel a
lot (in a way to reduce roaming costs).

Any chance to have it on a future product (gta-03 or 04 ;-)?
