[Q] Crazy, but antempting sim repair for the heck of it...and questions

---

So, I got a Samsung Infuse. Super duper cheap. I bought it knowing there was an issue--the last owner ripped the sim card out and tore off four of the pins on the sim tray. So I unsoldered the top of the sim tray (the metal sleeve), and added solder to the broken pins to try to get the sim card to get contact.

Well, no good so far. The phone won't see my AT&T sim card. When I boot the phone, I just try to hold the sim card pressed firmly against the tray---but no luck so far.

I was wondering, though--what is the purpose of the other row of pins (circled in the photo in red)? They don't seem to be connecting to anything...and what about the other two pins (circled in blue)? I notice when I short them, the phone reboots.

Can anyone else here take a peek at their Infuse and tell me if there's some other issue with the other pins? I'm trying to figure out why they're there.

Ah, of course! That makes sense. and so what about the other two pins on the left?

Hi Evan,
When you insert the Micro SD card it shorts out those 2 pins together. As far as repairing the SIM/MicroSD holder, there is no repair for it. the SIM/MicroSD holder needs to be replaced. I have the same problem and as of yet i haven't found any one who sales just the SIM/MicroSD holder. If you were successful, pls let me know. I am in need of one.
Thanks

Hi. Did you guys ever find a solution for this? Or somewhere that could sell the tray itself? Because like a retard I actually tore off a pin with a SIM adapter and now it won't work anymore....

Thanks!

they do sell samsung infuse housing for sim and sd card at ebay.

Hi. I have the same problem. I found that they do sell housing replacement for sim for about 5$ at eBay. I don't have soldering skill so if you are successful, would you mind post picture instruction steps?
Thanks
