Dual SIM connector

Hi to everybody!
Where can I buy a dual SIM connector (a hopefully general one,
mandatorily "NO CUT")?
Thanks!

Hi
Yes they are on E-bay but be aware they don't work with 3G sim cards,
but they will work with a 3G phone with 2G cards in it.
Mine works perfectly.

Is there such a thing as a 3G SIM card?

I've been using the same SIM card for many years in various 2G phones.
When I recently bought a 3G phone I just put my existing SIM in it and
it works fine. Are there some functions I'm missing because I don't
have a 3G SIM card, whatever that is?

Yes. It's called USIM.

Yes, all the 3G ones

Only on 3, Orange and o2, who require a special SIM card called a USIM to
access 3G services. Voda allow access to 3G services from a normal SIM card.

That sounds interesting... Did you have to cut the SIM? Where have you
bought it?

Chris,

The confusion here comes from the different ways each network uses the SIM
or USIM.

From a design point of view the USIM is just a SIM with the first byte in
every message changed so that future designs may allow a USIM card to be on
the same card as a loyalty card. I think that this is unlikely ever to
happen.

There have also been minor enhancements to the files on the USIM that allow
more functionality on it compared to the SIM. The most noticable of these
is a set of files that allow a complex phone book to be on the SIM (has
number groups, email addresses multiple numbers for the same contact). The
downside of this is that most SIM phonebook management programs do not work
with a USIM. (You are unlikely to be missing out on this functionality as
most phones have their own comprehensive phonebook).

The services you mention are network services (not SIM services) so work
equally well with a SIM or a USIM - but only if your network allows this.

As other posters have said 3, Orange and O2 arbitarily block the use of 3G
services for customers using a SIM while Vodafone and T-Mobile allow all 3G
services for customers using a SIM.

It is possible to have a SIM card that is both a SIM and a USIM. Networks
like Vodafone issue these cards to be compatible with the widest range of
handsets posible. This also means that most SIM phone book tools still work
too.
An earlier poster suggested that 3G services were only allowed on later
Vodafone SIMs. This is not strictly true. This is an issue with Voltage
compatibility. Early SIMs were issued when the standards only allowed for a
5 Volt SIM interface. 5 or so years ago 3 Volt SIM interface was added.
New handsets only support the 3 Volt interface so the old 5 Volt cards will
not work in these handsets.

There will be a significant change in SIM and USIM cards in about 2 years
time as the standards bodies have just agreed to make them USB compatible
and are in the process of agreeing simmilar contactless interfaces to the
ones used by London Underground and banks.

Hope this helps,
Bet
