Hey,
My phone is no longer recognising / finding a SIM card.
I was testing a different sim card in my phone and when I inserted it I couldn't get any network so I put my sim card back in and it fails to find a network aswell.
How can I test/find out fully whats wrong, I'm assuming it's hardware does anyone know how I can check the hardware and maybe potentially fix it, the phone is out of warranty as of two months ago.
Thanks

Does it actually say no sim on the screen?

Or if it isn't...sounds like messed up radio, or hardware problem, such an antenna.
Have you tried that sim in another phone? Or another sim in your phone. Could be something as simple as a dead sim, or something a little harder like needing to update your radio, or something much wors, like a dead radio or faulty hardware

I had an old sim that started being unrecognised in phones and what I had to do was put a little piece of paper bewteen the top of the sim and the holder to get it to work.

Yes sir it does say no sim.
I have tried a different sim and I have tried my sim in someone else phone, its not the sim card what has a problem.
Ive switched roms does that update or fix radio issues?

no changing roms wont change your hardware, if you want to see if changing the radio helps i made a thread on changing the radio and other firmware via fastboot:
HERE (post #5 for radio)it can also be done via a pc10img.zip flashed through hboot but at least to me the preferred method is with fastboot.
if its a firmware issue this will fix it
i doubt its rom related but of course trying with a known stable rom is best
doubt its an apn issue as "no sim" means no sim not incorrect sim
you have already tested your sim in other phones and other sims in yours, so its safe to rule out a faulty sim card
if its hardware then chances are the sim isnt connecting to the motherboard, either the pegs pushing against the sim arent making contact or the slot the sim goes needs to be resoldered in place (not fun)
possibly other issues causing this but start with the easier, less intrusive, possible fixes and move up
good luck!

Tried a new radio, problem still exists. It's hardware

Looks like you might need to send it in for repairs or sell it as is and buy a new one. Can't think of anything else to try.

I was just lurking around the forum and read that the sim card slot in the CMDA version is physically disconnected. I was wondering that couldn't it just be modded and reconnected to the board? Something like that wouldn't be beyond my ability, so I'm really interested in the prospect of doing so.

Sigh. . this again. This has been discussed a bajillion times. Just a friendly reminder that there is a search button. Anyways.... if I recalls there is no way to reconnect the sim card slot. And if I recall even if you could I thought I read somewhere that the CPU in our PLAYs is desinged for CDMA devices, still the same CPU as in the GSM model just a slightly different to work with CDMA frequencies...

I did use the search... but there wasn't anything on this topic specifically of reconnecting it.
But thanks for the info regardless.
I also found some pictures of the cdma board. from the looks of it, I'm assuming that there was no solder placed where the cpu would connect to the sim. But removing the heatshield, de-balling, and reballing seems like more effort than it may be worth.

Yeah I believe that was the conclusion from ages ago that it was simply not worth the attempt @ reconnecting the CPU to the SIM card. Sure would be nice to have it active but I do not think its feasible.
I came up with another theory. What if one of the little sockets on the board that the metal (on the housing) touches is jumping the sim slot?

There was a XDA member last summer that took photos of his phone completely taken apart as he attempted to get the sim card slot to work. I have not seen him since and if I recall he gave up on it after a few weeks of messing with it.
Here are all the SIM card threads I could find regarding activating the SIM slot on the R800x:

I know that sticking a verizon sim card in my r800x using CM9 did nothing .. until I removed it and got a msg on my lock screen that said "No Sim Card Inserted"..
My HTC ONE X now cannot detect SIM card. does anyone have similar problem?
When I insert a SIM, the phone show SIM card or the SIM Card cannot be detect.
I have tried three different cards, all with the same issue.
I am in Canada, and the phone is the HK version. Can I still contact HTC?
I have rooted the phone via htcdev.com. Will they charge alot for fixing the phone?
Thanks
Either the phone needs to be GSM unlocked or you may have a hardware problem, meaning the SIM slot is broken or came in pluged

And htcdev.com doesn't root htc devices it unlocks the bootloader. Make sure your not putting the SIM card in backwards or upside down

Oh, yea, I meant unlock bootloader.
I think there is only one way you can put the SIM in and insert the tray.
Will HTC charge for unlocked bootloader device like this defect?

You mean to repair it? I would try to get it repaired locally. Are you sure the phone isn't just locked to it's original carrier? If it is unlocked you need to consider how it was unlocked some methods of unlocking can void warranty, also check that site to see if it says any about voiding the warranty. That if you really want HTC to fix it and good luck with that if you do, they more then likely they will want you to file a warranty claim through the original carrier which you don't have an account with. Let say they did let you send it in, they may just sent it back saying warranty voided because of customer abuse if there is any physical damage to the SIM card slot.

I am sure it is an unlocked one. I can get cell signal sometime with my SIM, but a minute or two later, the "Cannot detect SIM" error message pops out. I guess there is lossy connection.
I will try to find a local store see if they can fix it first. Thanks for the advice.
And if I want to buy the parts for reading the SIM on ebay, does anyone know what it is called and what should I search for?

You can also try bending the sim card tray so that you get better contact with the pins in the reader... Be VERY careful if you do that, the sim try is made of very soft metal and can brake very easily.

Thank you guys so much. I think I have fixed the problem. No signal drop in the last 30 minutes!!
I opened the case today,however I forgot to take out the SIM card tray. When the case was apart, the tray was already very bended. I carefully bended it back a little (not completely flat), and randomly messed the SIM card reader up a bit with the pry tool.
I booted up the phone without the case, and applied gentle force to the SIM. AND IT WORKED.
After closing the case, I still got full signal strength.
I hope this can permanently solve the problem.
Thank you guys for the help!

SIM card Tape and Untape
Hello everyone,
This worked for me and it may work for you.
As this thread suggested, I applied several layers of clear adhesive tape to the back of the SIM card. I was nearly unable to re-insert the SIM card and the train into the phone.
After 3 days, this did not fix the problem.
Next, I removed the tape from the SIM card and re-inserted it into the phone. Problem solved!

I just bought a used G2 for my son to be used as a wifi phone. I successively rooted and have Andromadus jellybelly on there. The phone was sold as unable to read the sim card, and I am wondering if there is a method to figure out if the reason is software related vs physical/hardware related? Any suggestions on what to try?
If it didn't work stock and still won't work after tooted and custom rom I doubt its software/firmware
So that leaves hardware, it seems the sim tray comes detatched from logic board on some of these, you can try and resolder the tray or pick up a new one. Possibly something else but it will be hard to determin other than trial and error

Look at the contact pins in the sim slot, make sure that they're straight and "up". If there are any that are bent over or not sticking up properly, those aren't making contact and therefore the sim won't work.
My phone is constantly failing to detect the sim card, usually if I restart the phone or leave it for enough hours it will "find" it again.
Short of reflashing it I'm not sure if there's any way to determine if this is a software or hardware issue. The phone itself is a refurbished one (thanks to the phones insurance replacing it a few months ago), however it is now out of warranty. If it was a hardware fault, how much would it probably cost?
Thanks, Shaun.
The first thing I'd try is a different SIM card or a different SIM card insert (bit of plastic that the SIM sits in).
Has this always happened since you've had the phone?
or
Has it happened since you flashed the phone?
As for the price of repair I haven't a clue (i do all repairs myself), but my guess is in excess of £150
You may want to provide more information before other, more experienced people, come to your aid.
It's slowly gotten worse over the last few months (the first couple of times I just thought it was a once off bug or something, which is why it's very difficult for me to give you an exact when it happened).
The fact that its gotten worse in itself is leading me to guess its a hardware fault - I could have knocked or dropped it and not remember or something.
I don't have any other SIMs but I'll give flashing it to a different ROM or stock a shot first.

Does the phone say no sim card (with icon) or do you lose service?

It has done both, the latter's slightly more common though. Probably more often than both it will momentarily drop out, then come up with a "Preparing SIM card..." message.
Still happening after flashing it with a different ROM. Looks like it's probably hardware :/
Might be coxicial cable that connects the pcb with antenea board they do come off from time to time

Hi there,
i have a similar problem with my device:
network disconnects sometimes (for some reasons ok, as example when i sit in the underground or other places without gsm network) - but then the services doesnt comes back - i'm complete offline. next behavior: i'm just talking with full gsm bandwidth, and for really no reason i get disconnected -> no network anymore, no service anymore.
can it be a hardware fault or should i try to flash the modem (when possible) ? I'm on the latest HTC firmware, device isnt rooted or flashed... it is as i got it from the market.
thanks for a hint what i can try
See above could be that, what network you on?

I'm on GSM (in Germany the O2 network)
maybe the network fault can be solved:
just have read in the vodafone forum in uk and found a hint from a user, who was taping the back side of the SIM card with 2 stripes of plastic.
Have tried this and report tomorrow here if it solves the issue
Tested with taped SIM card and i can say: it works like a charme
Hello all!
I have a Note 2 who can't detect my sim card, listen to this:
3 months ago I started to get no sim errors, and after trying everything (factory reset etc), I finally decided to buy a new replacement sim tray.
I got it in the mail and replaced it right away. Damn I was looking forward to using my phone again!
Errr.... Still the same no sim error
Mabye I was extremely unlucky and the new one was faulty as well? Hmm.
I ordered a new sim tray, got it today and replaced the old one.
FFS! Still the same god damn no sim error! :silly: I'm going mad over this ****!
So, it seems like I got no choice but to buy a new phone. (The phone doesn't have any warranty.)
My question is: Has anyone experienced anything like this? Do you have any possible solutions?

Yes, tried 2 other sim cards, none of them works.
I just recently changed to Cynagenmod 10 from stock to see if it would make a difference, but still get "no sim" error.
Do you think this is motherboard related?
It's clearly not the sim tray itself that is the issue here

hard to say, but it could be issues with the board. does searching google give you any info? Try gsmhosting for more info.

Check if your IMEI is correct / the same as when you bought the phone. If you see it has changed or its is corrupt then that might be the reason
to recover your IMEI means recovering your EFS
there is a user here and a htread about recovering / restoring EFS by Drkeaton..something like that .. it very useful and might help u and that mans going back to Stock ROM other than that maybe flash some other ROM stock based though if all fail it might be a hardware fault inside some chip in the mother board !!
