Dual sim adapter

Hello,
i'm planning to buy a dual sim adapter for my tattoo.
I found two adapters, but they are both a little expensive:
Adapter 1
Adapter 2
Does someone has experience with these adapters? Or with another one, cheaper?
I just need something that allows changing the active sim without turning the phone on/off.

Problem with these adapters is, that you have to cut out the chip out of your SIM cards and put them into the adapter...if they dont sit firmly in the chip slots, you'll experience loss of signal all of a sudden...Oo
Also you can damage you SIM...badly!...it's somewhat risky...the first adapter you mentioned provided once the service to cut the chips out for you, but I think they don't do it anymore...

I didn't know we can use external dual SIM adapter. Thanks I'll try it today.

[Q] Home made Y cable for using with goldcard method?

I am attempting to make a Y cable using a few cables that I saw on Ebay, but first I need to know whether it will work or not. This is what I plan on doing:
1. Connect HD7 to original HTC cable
2. Connect the USB end to a female converter
3. Insert a Y cable to the female port (all sides of the Y cable are normal USB 2.0)
4. On one end, insert USB to computer
5. On the other end, add another female converter, and then a micro SD card reader
Do you think this will work? Please, I really need the answer urgently....I'm impatient
Here is a link to a picture I created. It can explain things much better

Thanks in advance, people!
Edit: I found some HD7 unlocking kits which I might be able to use for the goldcard method. Could someone please confirm whether they will work?

Just get a y cable

Hw mod: add an internal memory card holder?

Since this device lacks the microsd expansion slot, I was thinking to add it internally. I don't know yet if it's possible, but my idea is to add it in the sim card empty slot.
Do you have any clue about it?
Let's open a "project"?

Here is the mainboard of the 7310.
The idea is either we find another part of the mobo like the one ready for the simcard, hopefully ready also for a memory card holder, or we connect a generic sd holder to the usb pin of the main connector of the tablet.

Here is another piece of information... http://forum.xda-developers.com/showthread.php?t=1118986

Thanks, very useful.
Well it should be feasible, it's enough to connect the usb pin, but there are some questions to be answered.
1) If a memory card is inserted will a device connected to the 30pin connector work? Or does work only 1 device per time?
2) Will this kind of connection work like a normal microsd holder connected to the mobo by default microconnector? I mean, will it use more power, will it drain battery faster because voltages etc..?
3) will it be useful due to the possibility to install apps?
It's important to have answers to these questions, but the operation is very feasibile.

Well, I'm thinking that this mod using the usb pin doesn't worth the trouble.
Usb needs 5.0v and it's too much. Using 5.0 continously drain a lot the battery.
Instead a stock 3.3v powered microsd, is far lower battery hungry.
The problem is to find on the mobo the pinout (if present) to connect a microsd holder.
Gt-P7500 is ready for this connector, but as far I saw on pics of 7300's mobo there's nothing similar.
It would be interesting to read the service manual of 7300 just to understand if the chip and the mobo are predisposed for such a connection although not present.
Internet is full of 7500 service manual... but something for 7300??

I've found this generic adapter, ready to be connected on the equivalent pins on the mobo. The problem is to find the schematics of 7300, just to understand where and if are the sd control pin on the chips (but I guess so).

Hi.
Can anybody tell me, is there a flawlessly workind dual SIM adapter (perhaps without cutting the mini sim card ) for the S5 which works with DSC 2.3 and CM7 Roms?
