Is any one brave enough to perform this mode on their new SGN II?
http://forum.xda-developers.com/show...5#post32593285

I believe the little metal shield near the microSD slot is Sprint SIM-chip - it in the same spot as SIM slot on other versions of SGN II and it looks similar to the one in the above Motorola phone.

There is a dual SIM adaptor for this phone here:
http://forum.xda-developers.com/show....php?t=1952770

so theoretically it could be used to split the connection with Sprint SIM-chip and another real full size SIM

I would love to see the same thing. I was thinking about moving to the Galaxy Note 2 until I read about the embedded SIM. I hope Sprint backs away from this trend or at least someone can hack the Note to allow for SIM switching.

If someone can show the pcb board I will start to see if the sim slot can be modded back on to the phone but its looking like i have to wait to get my own to see if i can mod it

Some are slightly blurry but hope this helps, btw this thing comes apart just like the S2

Nice photos, can you make a video to show exactly where the sim card is and how it's embedded? Is it soldered or is it just built into the pcb board?

You will not see a real SIM card if that is what you expect yo see - It's an ASIC microchip.

the "SIM-chip" is clearly visible one of the posted pictures:

It is right next to the white letters SPH-L900
And as you can see it is almost the same as in Motorola Photon phone in the original thread:
http://forum.xda-developers.com/show...5#post32593285

First picture on the right (also has 880120000 on top) - just a different version
That original thread has couple videos with removal procedure, it would be exactly the same here.

Darkendvoid88, Thank you for posting pictures!!!!!

Ah, thanks for the clarification. Very daunting but at least I know it's theoretically possible. If only this was more practical!

It appears that you'd have to have the phone taken apart just to use the foreign sim card, which is impractical. Maybe it could be stuffed below or above the battery, of course assuming the little wires could fit through some crevice or crack somewhere in the back. Otherwise, this type of hack basically just makes it possible to find your favorite foreign sim card, stick it in and close the device back up.

When I traveled around Germany and the UK this summer, it was super convenient to just switch to the new sim when I needed but I don't see that this will be possible even with this type of hack. Damn!

The op just has it set up like that because the photon is sealed and has a "non removeable" back. There is little to no room for the sim reader. An extended battery back might make this easier for us. Also if anyone has ever taken apart an S2 there is a clip next to the battery terminals. Ours is the same dissassembly process and that clip could be broken off to allow for easy wire routing.

Not too be noob-ish, but this is possible, right? Because if not I just wasted $300 :/

looks like the sim reader would go right in same place as the GSM sim version either trim the sprint case to model it the same as the GSM sim version or buy a GSM sim replacement case.

You can't simply replace the chip with SIM card slot. You will lose Sprint LTE. To make it right you's need to solder a dual SIM adapter instead of the chip, then solder chip back in to micro SIM slot of the adapter and use the regular SIM slot for other SIM you might want to use. The software that comes with an adaptor will help you switch between chip and the SIM
