I've searched around and couldn't quite find the answer I was looking for. Hope this is the right spot. So I've been doing phone repairs on the side for a couple years, I don't claim to be an expert, I try to stick to just basic screen repairs and simple component replacement. I stay away from anything involving soldering because I don't have the equipment or the patience. Someone brought me a Galaxy s6 active today and he destroyed the SIM card reader trying to fish out his sim card with a (get ready for it) sewing needle! I explained to him what a pain in the butt the s6 actives are to take apart and get all the way down to the sim tray, which led me to wonder if there is any kind of adapter or external SIM card reader you can plug into the phone through the charging port and connect to the network? I come across these situations all the time where people have phones that have damaged SIM card readers and the repair costs outweigh the price of the whole phone. So is this possible?

Helloworld.
My symptoms: the device spontanely stopped to detect memory card (the card itself is functioning - checked already, as well as plugging another card into my pola), however the device reacts (wakes up) to the memory card insertion switch status changes (present/absent).
At a glance - all components on the M/B seem to be intact, however I didn't made it yet to unsoldering the card holder and watching inside for bent/absent pins.
Can someone provide me with a clue - what components on the polaris M/B are responsible for communicating with the SD card, and which ones of them I need to check to make sure they function properly?
No clue about that in "classified" service manual from wiki
Am I missing something?
I'm seeing the same thing - curiously problem also occurred on the 6th...
I'd be interested if you find a solution (I'l come back and post if I do)

So, finally got my hands on that one polaris I noticed lying around.
The problem itself was in card-reader slot. I never found the replacement for the slot itself, so I de-soldered it and soldered a micro-sd card right into place using small pieces of old ATA-166 cable lying around. Turned out not as good-looking, as it could be, done by a professional, but still does the job very well. Now device is functioning properly
However, the connector, that was originally on the M/B got 10 pins on the sides, 8 of which supposed to be connected to the micro-sd card. Maybe some1 here know why the hell there is 10 of them and what are 2 extras supposed to be connected to? Also, is the 8 pin supposed to be connected to the switch that represent card absence/presence?
Just before soldering you should try SD Formatter 2.0 for SD/SDHC (sdcard.org/consumers/formatter/) It almost saved my patience !

I dont believe it is possible... but if you REALLY DID IT... then youre really an incredible INSAN3 Genius!!!
PLease give me further details. Since I opened the Polaris to replace a broken LCD screen the SD card reader broke apart... now I'm using my polaris with the (small) internal memory only (sigh!)
...maybe it's right time for a new phone, but while It is still not broken at all... I would like to try to fix the SD in the way you tell us you did it!
My MyTouch 4g does not read any sim card. I have sim unlocked the phone and s=off. Ive flash all the radios non work! Tried 4 different sims (T-mobile, AT&T,Straight Talk (NOKIA E71), Simple Mobile) all failed. Flashed 5 different roms including the orginal.
Can any one help me????????????!!!!!!!!!!!!
Maybe the sims card sensor readers on the phone by the battery are damaged have u had anything get into yo phone like dust or water
HTC Glacier (Black) - Virtuous Unity 2.39/Kernel V9 Unity/Beats Audio/Good Screen/Good Emmc
Are you inserting the sim card the right way?
i havent got any water in it. I have to check for dust and yes im intersting it just like the picture on the phone
The first thing I'd go with on something like this is a physical problem.
Is the SIM card seating properly in the little slot? There's that metal bar that goes over it to give the springy connectors something to push against to form a good contact. It's possible that the connectors aren't being pushed into the card enough.
It's worth a shot to push it in with a finger with the battery cover off just to see if you can make a connection. If you get anywhere with that maybe try cutting a playing card up and sliding it in over the SIM to basically make the SIM card a little big and tighter in the slot.
Since different cards aren't working and different ROM's don't fix it it's a fair bet that you're looking at a hardware problem. If it's an electronic problem you're screwed. If it's a "the slot doesn't hold the card tight problem" you have options.
May be too simple, but did you put your SIM card in the wrong way? Haha, don't be offended, because I am not trolling in any way. But this happened to a friend of mine the other day.
I actually joined this site for the same problem but my WiFi and Bluetooth don't work either. Mine is obviously a radio problem but I can't seem to get my phone to flash new radios...
My A2 sim card connector has broken..
i'm gonna open the cellphone and try to fix it.. but i'll probably need a new one..
I googled for a long time but only found it at cellphone-repair-shop..
does anybody know another website with atrix2/motorola parts?
Thanks!
I know this is a very old post, but did u manage to get ur hands on the sim tray??
My reader is also destroyed. From that I see you can solder it very easy. One day I'll try it, because Atrix 2 is not my main device. So if I'll destroy board by soldering new socket - there wont be problem.
I posting my destroyed socket picture.
Some news.
I desoldered SIM reader with success. Phone still powers on.
Now I only need to buy new reader and solder it and see if phone accepts new sims. So stay tuned.

I've been researching this issue and have found a lot of threads about bad/corrupted SD cards randomly unmounting themselves. But the issue my phone seems to have is that the SD card isn't securely seated, and I haven't found much, if any, info on how to fix it.
Basically, my SD card unmounts if I bump my phone the wrong way. More often than not, it happens when I'm putting the battery cover back on. I did some fiddling with it, and once the card is inserted, if I gently pull on the card towards the edge of the phone, it unmounts. If I gently push it back towards the center of the phone, it remounts. I don't think it's an issue with my particular card (SanDisk 32GB Class 4) b/c I've tried two other cards (another SanDisk and an Kingston) and they all do the same thing.
I've tried pushing down on the card slot a bit to try and tighten up the metal sleeve that the card fits into with no luck. I've also tried putting a small piece of tape on top of the card to make it seat more firmly. Neither approach works. If anyone has any suggestions I would greatly appreciate it. I just got the phone recently and have been very happy with it (MUCH better than my old Droid RAZR). But I take a lot of pictures w/ my phone, so having a sketchy SD card is driving me nuts!

Sounds like a hardware problem to me.. If i was in the position i would just get a replacement fone
Maybe it has come up before, but I wanted to create a quick thread about this issue, because it has seriously began to getting on my nerves the last couple of weeks.
In the beginning when my phone didn't detect the sim card(s) I simply had to reboot.After that I had to remove the sim card manually and insert them back into the slot.At some point they weren't detected at all.
I searched in the Lenovo forum and found this thread:
https://forums.lenovo.com/t5/Moto-G...lus-SIM-card-randomly-disappears/td-p/3543823
For now I've cut out a tiny piece of paper and put it between the sim card and the top side of the slot, rebooted and voila.
My both cards were detected.
I've ordered two adapter, because the method with the paper is provisional at best and hopefully it will solve this until I get a replacement for the cards or buy a new phone.
With best regards
