havin' sim issues...

i just got my dash and it is actin strangely. it keeps goin between phone & flight mode and it sometimes turns off the phone function or says...''sim failure, sim card may be invalid or missing''. please help as i am getting irritable without my fone.

Maybe the SIM card has somehow become wet or unseated. Remove it, wipe it down with a soft cloth, and reinsert it. The problems may go away.

Take a pencil eraser and rub the SIM card contacts on the phone and SIM card itself.

thanks alot guys...
big thanks for the eraser tip. it still does it occasionally but i can use my phone again... thanks

ohhh booooyyyy....
it's at it again but the eraser thing wont even work so i'm back to square one.... and i tried to use the eraser on the sim contacts on the phone but i can't reach them to do it as they are behind this metal strip which i guess holds the card to the contacts. i did notice that the same metal strip is also soldered to the board, could there be another use? i was wondering if it was able to tell that the card was there via this bracket as well as by the pins on the sim port, if so maybe it was loose or something?(just stabbing at ideas)

I once had this, I did a hard reset and that solved the problem. Make sure to backup your data first.

why dont you try another sim card form a friend or something.
like that you can determine where the problem is coming form.

[Q] Micro-sd slot spring loaded?

Bit of a weird question, but I recently bought a Desire with serial number HT09 and the micro-sd slot was just an interference fit, and I had to pick the card out with my nail.
This phone has just been replaced due to rebooting issues and the new phone I received from t-mobile has s/n HT08. This phone has a spring loaded micro-sd slot, so I just have to push the card in to eject it.
This to me seems like better attention to detail, I just wonder why they changed it?
Was it maybe made in a different factory?
Cheers, Rich.

the first few weeks I had mine (HT05) I was picking the card out with my finger nail but then the spring 'sprung' into life and now I push down to remove it, so I can only guess that they all have springs fitted and that some work properly and some dont

The HT04 lot are fine.... cant see thay would take the spring away ... it's still very fidderly to get the card out... far too small !!!!!!!

[Q] G2 SIM Slot acting up. Replace?

Tmobile G2. Started losing network every so often. Would need to reboot or sometimes switching to airplane mode and back would work. Then it just wouldnt work at all. Went to Tmobile store and they gave me a new SIM card. Tried that, and still no luck. SIM works fine in other phones.
I tried multiple cards, and they seem to work fine so long as I apply heavy pressure to (push down on) the card while using the phone. If I let go, the network drops within seconds. Must be the SIM slot itself..
Anyone ever replace the slot on a G2? I think it's soldered directly to the board, but I havent taken it apart yet. Hopefully it's just a few points that I can easily remove. Where can I get a replacement though? Anyone know parts that have matching solder poins?

yeah its soldered to the motherboard and unless you are amazing at soldering it will be tough, to top it off I've never seen one on ebay or amazon so you'll have to dig for one

I've been looking for the part too, had some luck just resoldering the old one, twice(!).
CAREFUL if you do this. AND DON'T push on the sim slot. This will wreck/crack the traces for the solder for the SIM holder itself. The holder is soldered to the surface of the MoBo. Mine (mobo) got damged on the second solder operation, some traces came off of the board. There is a place I found that will repair it for you for 89bux, but seems pricey to me.

looks like compatible sim holder

I'm going to order it (only 1 buk) and give it a whirl. Will post results.

what was the result?

Sim card tray damaged. Best way to fix?

I have a tendency to hop back and forth between phones. Today I went to put my sim card in my Note 2. I use a nano sim card adaptor (I decided to experiment with the iPhone 5 for about a month...) to put my sim card in my Note 2 and my Nexus 4. Unfortunately, the sim card fell out while I was putting it in my Note 2 today and the adaptor got stuck in the tray. After a few moments of agonizing struggle, I got the adapter out. Now my Note 2 won't recognize my sim card. I think the prongs at the entrance of the slot were damaged, since that's where the adaptor kept getting hung up.
Is there a way to find out if it's completely broken or if the prongs are just out of place? And if it's broken, does anyone know how much a repair would cost? I don't know that I have the confidence to try to repair it myself.
Thanks.

The SIM card reader module I'm fairly certain is soldered onto the logic board, so unless your good with soldering, a replacement SIM reader isnt very practical. However, the Sprint Epic Touch (GS2) sd card reader module is attached only by a simple flex cable, so its possible the same may apply here. If this were the case, the replacement part shouldnt cost more than 10-20$ (assuming their available) and replacement would be as hard as taking the back housing off.
Try comparing the SIM slot with another similar model and see if you can see if something is out of place. See see see see see see.:good:

I think I may have done the same to mine with one of those SIM adapters. I've ordered this and it should be here in a few days. I'll give it a go...

u did the same exact thing i did lol but what i thought was a damaged sim tray was somehow just corruted firmware when i restored back to stock everything worked just fine i even called samsung and they were going to replace it but since i live in Hawaii i didnt want to wait so i just did a restore in odin and everything works fine
if u are really damaged ur stim tray and dont wanna wait on samsung u can try this

but good luck try restoring with odin first

I'm glad I'm not the only one to have had this problem, heh heh.
Anyway, after watching the video, I think I'm going to send my Note to Samsung and have them fix it. I would probably ruin my phone if I did it myself. Should I do a factory reset to protect my data before doing so? I don't know if they'll be sending the same phone back to me, since it says they may replace it with another if they determine that they aren't going to fix the part that's broken.

they will wipe ur data if ur rooted and have a custom rom on your phone u need to return to stock and set the flash counter to zero.
u would send the phone is no battery no battery cover no sim card so sd card just the phone nothing else
try to restore ur phone via odin first

if u still get no sim card error after doing that then give samsung a call phone number is on the phone itself under battery and they will send u a box and u should have to wait about 2 weeks then u will either get a fixed phones or a replacement not sure how they do it since i fixed my no sim issue with odin

I did the same thing once. Just called att and told them it wasn't reading a simple anymore and they sent me a new one.

My Fix For Broken SIM Reader Pin
This is an old thread, I know. But the problem is ongoing. These SIM card adapters are just plain evil. Now that this has happened to me, I googled the issue and see that there are tons of folks suffering. I am posting this reply so that others can see the "fix" I managed for my International Samsung Note I. I am sure it can be applied to most other phones.
I should point out that in order to get any usable access to and visibility of the SIM card reader I had to remove the battery cover and the back from the phone's touchscreen. This reveals the motherboard to which the SIM card reader is soldered. I found a good video on this at YouTube. It wasn't that hard although I did not have the plastic pry bar they used - I think I will get one for the future. I managed with a small flat head jewelers screw driver and an ancient, plastic shirt collar stay. (I can hear my mother saying "save it - you'll find a use for it!" I hate it when she is right.) Once complete I could move on.
At first, I tried to replace the SIM card reader pin that was broken off by the SIM card adapter with a tiny piece or rolled-up tin foil. I saw someone else reference this approach and it seemed possible and cheap. Alas, it did not work. After many attempts, the phone simply would not recognize any SIM card. I finally got to sleep at 3am.
I then found a piece of brass shim stock that I have had lying around for years. (I am hearing mom again!) It is item 1412110231, Brass Strip .016x1/2inx12in shown here. I got mine at the local hardware store for some other aborted project. I used some snips to cut off a tiny strip from one end and then cut that strip to maybe 1/3 to 1/2 its overall length. The idea was to place the strip inside the SIM reader slot where the pin had broken off in an effort to create a contact point to replace the pin. Cutting the tiny strip off the stock piece caused the tiny strip to bow a bit. It turns out that was a good thing but I had to reduce the amount of bow quite a bit for it to fit inside the reader. Remove any rough edges from the tiny strip with a file.
With the touchscreen assembly lying flat on the table I managed to get the tiny strip in place. I was then able to slowly and carefully slide the SIM card into the reader and this resulted in a contact good enough to make the phone again recognize the SIM card and for cell service to be restored. Hurray! Yes, I was able to carefully place the battery in its bay and operate the power button to perform testing.
But you must remain aware that the tiny strip is just lying in the slot and is held in place only by friction/pressure from the SIM card inserted into the reader. Therefore, for the rest of the phone's life, it requires great care when removing the SIM and handling the phone when a SIM is not installed . Basically when removing the SIM, the phone MUST remain flat on its display until the SIM is re-installed. Moving the phone around in other orientations without a SIM card installed will definitely cause the tiny strip fall out. And who knows what hell that will cause?
You cannot put the phone's back onto the touchscreen with the SIM card in place. At first I thought about cutting the SIM's length down so the back would install even with the SIM in place. Before doing this I tried to carefully snap the top portion of the back onto the touchscreen while it all remained flat on the table so the tiny strip wouldn't move. With the top 1/3 of the back snapped on, I could just manage to insert the SIM through the phone's cover and have the tiny strip held in place by the SIM while I snapped the rest of the back into position. This worked pretty well but your mileage may vary.
I basically plan to leave the SIM in place forever - even if it is not to be used. I also put a reminder note on the battery so that I am less likely to forget that I made this hack.
I hope the annotated photos help those who follow me - as surely others will do. Good luck. I was very lucky to have destroyed only one pin and for it to be in the most accessible part of the SIM reader.

SIM Card is not detected anymore after i dropped phone

So apparently it wasn't a bad drop, nothing happened to phone (no cracks or anything) everything is working fine expect sim card, it says ''No Sim Card, Emergency Calls only'' and when i remove card a notification pop up saying ''Unable to detect sim card'' i tried other sim cards and none of them works so i'm guessing its a hardware damage?

Just because there is no external obvious damage, doesn't mean the internals are free of damage. Almost certainly, you broke the SIM tray. You might try to "thicken" the SIM with a piece of tape (don't cover the gold contacts) and see if it cause the SIM to make better contact inside the tray. Be careful you don't put on too much tape, and get the SIM stuck inside.
Other than that, you probably need the SIM tray repaired, or other similar hardware repair.

I forgot to mention that my sim card started working somehow 2 days ago and the problem didn't occur after, if it happens again I'll try what you said. Thanks : )
