Hello,
I recently acquired an HTC One M7 and I started playing with it. After a while, I switched to a different ROM, namely AICP and after playing with it a bit more, I ended up deleting something related to sound enhancement. Everything was fine at this point.
The next day, early morning, I had to make some quick calls, but when I made the first call, I realized that I have no sound input / output during a call, although the music player worked as usual. I proceeded to hot swapping the SIM to another phone (as I said, I was in a bit of a hurry). The HTC did not turn off, while I did so, but when I put the SIM back in it, it did not detect it anymore.
It's been showing the NO SIM CARD message ever since, although I changed a couple of ROMs, including CM, Viper, Android Revolution HD and I tried the tape on the backside of the SIM card trick, I cleaned the SIM as best I could and I even tried different ones.
Finally, I wander whether I managed to somehow damage the slot of the SIM card, since the SIM works perfectly fine on my other phone.
If any of you experienced something similar, please, let me know how you solved it.
Thank you!
Have a nice day!
I have been able to hot swap sim cards on HTC One without an issue.

I always put my phone in offline mode before swapping sim card. Putting tap will not help. Just try to rub something on the sim card and check that all the points are touching the sim.

I tried rubbing the SIM against microfiber after cleaning it with alcohol and I even used another, new SIM.
Unfortunately, I cannot really check whether or not all points on the SIM are touching slot contacts, since opening up the HTC One M7 is really hard and that would be the only way to actually take a look at the slot.

hi guys,
i got TYTN II brand new whenever simcard inserted, phone start up then switch off itself.
without simcard start up ok, go all the way to the main screen.
is this to do with the Radio rom?? i flash with the original rom still no luck.
have anyone here experience this
thanks
Sounds like the SIM card isn't inserted well or the contacts are dirty (or could be the SIM card). Try cleaning the contacts on the SIM and device first and make sure the door is securely shut.
I think you have this confused. When you switch it up it turns off the phone so you can turn it on and the phone recognized the sim, if it would stay on when you put the sim, it wouldn't recognize the sim, so put it in then keep it in and turn it on and it should have recognized the sim. If you know that already, then do what Jwy said, I recommend rubbing alcohol and 100% cotton.
my device is working ok, but everytime i just unlock the sim card slot (without touching the card itself, my device shuts down, no matter which rom or radio rom.
It's no problem for me because i've just got one single sim card, but if i would have two different sim's....
Is this the standard behaviour ? I think it's strange, just curious about that...
that is normal , there is a little switch behind it that turns your device off .
some kind of protection.
Right, most phones have the sim under the battery so you must pull the battery to insert the sim. The Kaiser cuts the power with a switch on the sim door to protect the sim from a "hot" insertion and possible damage when changing sims.

Another TYTN II i have is working fine with this simcard.

No man, no confusion here, i know how its works
you didn't read my msg propely,
" switch off when simcard in the phone" if i take to simcard out, the phone boot up fine, ok
i switch it off then put simcard in (clip the simcard's door) then turn the phone on, just say HTC logo then switch itself off
ADD:
i mention that i got 2 TYTNII ok.
i swap the motherboard between eachother, still the same.
so i think either RADIO ROM or HARDWARE !!
so i want opinion here, whether its the HARDWARE OR SOFTWARE???
thanks
Ah, ok. You don't have to get mad . It could be software. I have seen this happen to people. Try a different rom & radio.

Hi
ive got a problem whereby my phone stops recognising my simcard and i can't
get it to recognise it unlless i hard reset
the hard reset works for about 3-4 hours and then it stops recognising it.
( during the 3-4 hours i don't move the phone just so it HOPEFULLY proves it isn't hardware.
Any Ideas
thanks ben
( it is on 02 and i have tryed other 02 cards and an orrange card )
I know this has been covered a few times and can be found easily using the search...
Most liklely it is hardware, as the ROM does not really ever affect that. One thing to try is when you open the sim card door, there is a metal bar that goes over the card and holds it in place. Remove the card and press down on the tab untill it touches the golden tabs below it. Then put the card in. This should put pressure on the card and keep it connected. If that does not work, you may need to replaced the sim card reader
Hardware definitely. Had the same problem and luuckily had extra parts. Swapped it out and works like a charm now.

Swapped what out ?
The SIM card reader ?
Where would I get one ?
Who would install it ?
I have this issue and I want to go back to my TyTN II.
Thanks.
I wouldn't count too much on the hardware. When i got my Kaiser yesterday (slightly used) it recognised every simcard i had in store, except my own, which i wanted to use. Simcard in different phone (a soaked Herald, but somehow sometimes working) told me the sim was fine. So i transferred my contract to a out-of-the-box simcard from KPN-NL, and that one somehow worked. I didn't really bother to have another thought about it, but is it a known hardware issue then?
I have a Developers Edition, using an AT&T sim. I just got the sim about a month ago, as my previous phone had a normal sim instead of a micro. I'm running Android Revolution 8.1.
Intermittently, about once every two weeks, I lose all connectivity and it says sim card not found in the status bar. I reboot the phone and everything is fine. I've tried removing and re-installing the sim card twice now.
Has anyone else had this issue or know the cause?
I had that happen to my DE for this first time this morning. A reboot solved it (for now). If I'm not mistaken, this happened on the HTC One X and a number of people got new SIMs only to have the problem resurface. I guess we'll have to wait and see how many others are affected or if it's limited to only a handful of devices. I doubt if there's anything wrong with your SIM card, but AT&T will give you a replacement if you want to go that route and see.
I used to have the problem one my one x, it was caused by a poorly fitting sim tray combined with the body and back not being completely rigid (it was the same underlying problem which caused the screen flex and wifi problems on the one x). I solved the sim problem with a new sim tray but the underlying problem always remained of course...
Hello,
I am with international HTC One and I have already had this issue twice. But for me, rebooting the mobile does not solve the issue. The first time, after having switching 10 times with some other cards I had, it suddenly worked when I put the card from an Iphone.
This night, same issue again ! Up to now, even with changing with the same card, it does not work !
**** ! I don't know what to do......
Any ideas ?
i have had same issue with my ex One X . Went to service and replaced mobo.btw while all process service guys scrached the body,lost bluetooth sensivity,lost wifi sensivity,green-orange led became bigger light.
i hope something wrong with your Sim.or store can replace with new one . otherwise bad days waiting for your One.
Found this solution in another forum. Sounds like it might work.

I recently purchased Nexus 6 and since it uses nano-sim, I used a sim-card cutter to make my micro-sim a nano sim. Worked fine for a while but then all of a sudden I started getting messages about no sim card. Reboot always fixes the issue, but this happens like 30 times a day, so rebooting the phone that often doesn't seem like a good idea. The phone also freezes all the time, no matter what I do, and then at other times it works like a wonder. I've had a Nexus 6 phone before (this is my 2nd) and it had the same issue. Apparently nothing was wrong with it.
Is the SIM-card causing these freezes, or is this a part of the world-wide issue that has been reported recently in the media? No other phone has had issues with my SIM-card, even though I used the cutter to make it nano. So I doubt it's a faulty sim-card. I've tried LG G4, Xperia z3+ and others and they've not had any issues with the cut sim.
edit
I've noticed the freezing happens most when I've recently charged the phone. Last night I left the phone on charger and when I woke up, the phone had switched itself off.
edit2
I've tried resetting the phone, also hard reset. Didn't help.
A method to check if your cutted sim card is damaged or not is to remove the sim card and replace it with a working sim card of another phone.

It happened to the wifey, and swapping with my SIM confirmed it.

Yep. I switched the sim and works fine now.
My devices sometimes cannot read the sim card, and some times it can. No matter what sim I use, what ROM I use, and I've even tried another sim card reader, but the problem seem to be something else.
Anyone experienced this?
I've been looking for a way to emulate a sim card, like a soft sim solution, but it seem this is not easy..
Maybe it's time to let the old m7 retire...
Anyway, thanks to all contributors in this community, it's been awesome. Merry Christmas and a happy new year.

Maybe the sim card isn't making a good contact when inserted in the tray, A few ppl got a similar issue and used paper to shim the sim card (not recommended since your sim tray can get stuck). I would try another sim first...

Yes, that's a common issue. The first steps was to use a little tape on the sim, second step was to try another sim, third step was to open the device and take out the sim reader, clean it with ethanol, check every pin and so on, then I tried another sim reader, but the problem still remains.
I too have the same problem, of signal on and off. I think the device detected the SIM card as it asked for PIN to unlock. I tried the *#*#4636#*#* to choose WCDMA only / preferred, but still same problem. So, did you retire the beautiful phone of yours?

Since not even replacing the sim reader solved the problem, it can no longer be used as a phone.
And anyway, the battery is getting seriously old, so when my dogs destroyed my remote control, the good old HTC one m7 now have a new life, filled with joy and happiness.
Anymote app is nice, and m7 are now a media control hub in my living room.
Since April 29 2013 this device have improved my life quality, with the good help from this great community on XDA.
