Dual-SIM solution that works!

[M4cr0s]

Hi

As you probably are are aware of, there's been a number of different "multi-SIM" or "Dual-SIM" solutions through the years. Lately there's been problems with the 3G-SIMs that would not work properly with the various multi-SIM solutions.

I've found one that works for my two new 3G-SIMs.

This one is made in china and is very basic (which seems to be the key in finding a working solution with many 3G-SIMs/phones - basic). The shop linked to is Norwegian, but the text concerning this particular item is in English. Regardless, this spesific solution is made by several different brands, charging from 5 € upwards to about 60€. The difference being brands of course, and how advanced the built-in STK meny is. I have seen this particular one that I bought several other places on the net (I recognize the packaging/logo).

Basically what you do is you cut out the chips from the SIM-cards and insert them into a special SIM-card like device consisting of a very thin curcuit board and a small microchip. This one is about the size of a normal SIM-card and can be inserted into your Kaisers SIM-slot.

Note that I didnt actually have 3G enabled when I made those screenies, but it do work! ;)

As you can see, along with the network name (NetCom in my case on both SIMs) I've specified my numbers and they will automatically show up along with the network info. I.e. "YourOperator YourPhoneNumber".

How well this would work if you change networks (my two carriers both use the same data-settings, one being the owner, other leasing capacity) I'm unsure, but I suspect the phone will ask you to reboot if you want to have functioning data-connections.

Well thats it!

but is very dificult cut correct the sims

[sniperess]

So only one line will be active at a time? Like I can't receive a call on both lines and have it auto switch. I would only be able to receive calls on the respective active sim?

[M4cr0s]

No, you can only have one number active at the same time. As far as I understand this is a limitation in the phones hardware (not the Kaiser spesifically) according to certain regulations etc. Having more lines to one number is something else, a service certain operators offer, must not be confused with active numbers.

You can set the STK to autojump back and forth between the numbers, but I find this feature pretty much useless. This Dual-SIM solution should tho work very well for swapping between lets say private and work numbers w/o having to change phone. Or, having a backup number in case your prepaid runs out etc.

I did not find it very difficult to cut out the chips from their original SIM-cards, a pair of schissors did this job nicely, as long as you use common sense and follow the guidelines included in the package.

Try googling for "universal twin sim card adapter". Seems to be what the producer call it. I got it from that site I linked to, I'm in Norway.

Not all of them fit in a Kaiser.
We need one in The Netherlands, that fits in the kaiser.

[M4cr0s]

Not all fit no, but this one does, confirmed. Thats what this thread is all about ;)

Here you got sites that seem to sell precisely the same one as I've used.

Did you see the "Not for use with 3G (USIM) SIM cards".

3G compatible adapter are expensive ( 30-70 EUR ). Do you know where you can get one?

[xmoo]

I don't know if I have a 3G or normal SIM.

My #1 number is from Telfort, when I connect to the web only gprs works.
My #2 numer is from Vodafone but it's a prepaid, but sometimes when I connect to the web G, 3G, H works.

SO I think I need one what supports 3G?

Its Dano/Swe/Nor actually ;) Its 8-9€. Should be that price or a little less from other sites (high taxes in the scandinavian countries).

Where dis you get the Sim ToolKit app from ?

You get it when you buy it.

right?

[M4cr0s]

Its not an application per se, its like the SIM-card menu on your operators SIM. At least most operators have some kind of STK menu on their card with various functions. The menu on the dual SIM thingy is the same kind, only that it let you change active numbers. It will pop up automatically in your programs-menu when you insert the dual SIM and you don't need to install anything softwarewise.

are you sure they are working in 3G mode ( and not GSM/GPRS/EDGE ).

Last time I tried such a cheap adapter the 3G sim worked... as a GSM sim ( no access to the 3G network ).

You can get them overhere at dualsim.nl i think.
i used to have one but it ruined both my sims. not handy when travelling..

Succes, Steven

[M4cr0s]

Well I am able to enable 3G and use the SIMs for data and calls with the 3G/H up on the status bar and everything. I haven't tried video calls tho.

This is sort of something I tried to make clear in my first post...and also the reason this product is interesting...

Ebay?? £6

lol

[umarulc]

I have been using these since Oct. 2006. They worked excellent with 3G, video and data (3G UK). The problem is that if you use it 2 or 3 times (mean put the sim cards in and out etc but as long you dont remove it from the phone they will work) it will be demaged. There is an instrument which is used to cut the sim cards to fit in that. I have that instrument.

What happens when using sims from different operator ie one O2 and one T-Mobile. Does the network wizard start every time to change all the settings over? or does it manage them all?

this speek for me....

I 'have been using simore card in my Kaiser and the network scan restart each time I shift from one sim to another. This sounds normal as Kaiser Has only One GSM/GPRS... module (as 99% of the phones).
Nevertheless there is some dual-GSM-module phones on the market wich entitle you to be connect on both phone numbers (or phone sim card + data sim card) at the same time (no shifting needed in this case).

FYI, Simore cards do not support 3G protocols: I had this problem and phoned Simore company and they confirmed it. I can only use Edge as the best protocol available for data.

I bought the one in the second link and I cannot get it to work, I put in both sims and it detects one but I cannot switch between the 2, I cannot make any calls or anything with the sim it does detect and I do not see the stk menu program ANYWHERE. Where do I get the stk menu program or do I have to install it or something?

[gazzacbr]

thanks laubet for advise about simore not supporting 3G. i was on the point of buying one,

features list from simore website

Support all GSM SIM cards (SIM & USIM)
3G and GSM mobile phone compatible

the 3G 'compatible' bit is really misleading and suggests that 3G is supported :mad:
