Is there anyone here having an issue with their SIM Toolkit disappearing sometimes and then appearing when it feels like.It has been bugging me a lot
I have the same problem on a Pixel 7. No idea what to do though but I am actively looking for a solution. If I will find it I will share it here. Did you find a solution to this problem?
The same problem for me my Physical Sim randomly disappears and then appears again. ESIM has no issues. I thought my SIM Card has gone bad, so I removed it. I will replace the physical sim card and try again or wait for the fix.

You misunderstand. Sim toolkit is an application on the phone.

If I remember correctly, it could rename itself based on something from cell service provider. You sure it isn't just named something different?
And typically also, you can find (some of) the controls it affects within the dialer also.

Just got my Kaiser, lovely boxing, lovely phone but I've had a little unpleasant surprise - I've entered SIM card while phone was already on. In result Kaiser have just crashed - I mean switched off itself. Anyone else noticed similar trouble? Does it mean there is still need to switch the phone off before changing SIMs?
Anyway, going to explore Kaiser.
its not a crash, its just what it does from what I have read, so i guess its just not "hot swapable"

It seems like - switching off occurs in the exact moment of unlocking SIM card cover... Well, shame - SIM hotswapping would be really cool
SIM card hot swapping is really bad. I work at a Operator and you don't want to know what kind of network trouble this can bring.
I've also had the Kaiser for a couple weeks now, and yes, it is supposed to shut down when you open the SIM cover. It's just for your own protection, you can even break your SIM if you remove it while the device is on (and, has a electric current flowing to the SIM).
thats what many design work are done to prevent users from doing things dangerously. If you've noticed, that all phones SIM cards are hidden under the battery and/or blocked by the battery in one way or the other. That's to force user to shut down the phone before doing anything with it. I'm sure that's for the protection of the SIM and/or not making a mess on the telco system, which may heavily affect the phones popularity
Not true. Another HTC handset with easy access to SIM card slot locatyed under slide out keyboard:
HTC VOX
also:
HTC TOUCH - side access to SIM card

It's actually in the manual. Page 24 section 1.2
Always turn off your device before installing/replacing the USIM/SIM card and battery.
Cheers.

Interesting.. I'd guess I'm at the old age. I did a bit of research, it seems that THERE ARE phones out there that can have hot-swap SIM. This is news. From Nokia N93 review
The hot-swap SIM slot is a very good solution, especially for users having more than one SIM. It allows you to exchange SIM cards without the necessity to switch off the phone and remove the battery. It is enough to switch phone in offline mode while changing card. At least it should work and it works on N90 just fine but on N93 with the current firmware version it is impossible to remove the SIM card even in offline mode because it causes prompt freezing.

Such as? Hotswapping SIM card from network's point of view looks exactly the same as removing battery without actually switching off the phone, as many people do. In such case network get no notification (IMSI detach) at all about switch off, and the only 'trouble' is network still 'thinks' that user is reachable until the next PLU (Periodic Location Update) or call attempt..
Well explained article on this: http://en.wikipedia.org/wiki/IMSI_detach

That's reasonable explanation. I have never got SIM card damaged, but I'd rather prefer not to experience it in future. In fact, my the very first SIM card I have *ever* had is already over 8 years old and still works perfect.
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.

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.
Hello,
my Xiaomi Mi 9T Pro running on stock MIUI Global 12.5.1.0 (RFKEUXM) can now suddenly not connect to my mobile carrier.
I hope somebody can help me out.
Some facts and stuff I have tried:
The connectivity icon on the top is just grayed out now and shows an X.
But that was not the case in the morning today.
At that time it showed full bars, but not the usual 4G text and the mobile internet did not work. After some attempts written below it is now just gray.
Mobile internet and cell service do not work.
I have rebooted multiple times.
The IMEI for both SIM slots is shown as 0.
No baseband version is shown.
(I am sure that this was also not the case early in the morning.)
I have never installed a custom ROM on this device, bootloader was never unlocked.
The SIM card is correctly inserted and the phone number is shown in the settings for SIM slot 1.
Trying SIM slot 2 (incl. reboot) did not fix the problem.
The SIM status shows that the service is not available, also on the top left when the phone is locked. ("Dienst nicht verfügbar" in German locale.)
Trying the SIM in another phone works, which I think makes it not a carrier problem.
Trying another SIM in my phone also does not work.
I unfortunately had dropped the phone days before, but no damage visible at all (phone case FTW).
Also it worked without problems, which makes me hope this is not hardware related.
WLAN works, so internet connectivity is possible.
Phone is out of warranty.
I did search for other threads with similar issues, but they all seem to be related to having flashed custom ROMs and then losing the IMEI.
Does somebody have any idea how I can fix this?
Thank you!
Edit: I just remembered/saw that I did do the "Xiaomi Service Framework" system app update to version 6.0.6-G yesterday night, maybe that caused the problem? Currently researching on how to roll that back. If somebody knows, please do tell.

Did you check Settings, SIM cards and Mobile networks, SIM 1 (if SIM is in Slot 1)
Do you have Turn on? If Turned Off, then do Turn On
If not, ie if it does not recognize the SIM card, then it looks like a hardware issue
Assuming, as you say, that SIM card is ok, correctly inserted, and that phone runs only the stock firmware - hence no root, no custom ROM, no custom Recovery (that user could possibly wipe partitions), etc
Maybe, some connection got loose and later disconnected completely
Thanks for you answer.
I am sure the SIM is inserted correctly and working. It's been in there probably for years now.
Don't know if you saw my update above about "Xiaomi Service Framework". Checking that right now. Maybe I should just do a factory reset.
What I have noticed now a couple of times is that the phone crashes and reboots, just now happened when I connect for USB debugging or before when trying to enter the SIM pin after a reboot, ...

Agreed, therefore I am sure the SIM is recognized. The phone even shows my number and the SIM has the carrier name.

If the carrier name is recognized, then IMEI cannot be NULL
Very strange
Try to play with Preferred network type setting
Maybe something really got wrong with the updated Framework

AFAIK too - but without IMEI it could not attach to the network and therefore cannot show carrier name
Hence strange, and/or the contradictory descriptions/observations

Ohh, sry there is a misunderstanding.
The carrier name is only shown as the NAME of the SIM card (I guess it is stored on there or the phone has remembered it). But there is NO connection or carrier name shown in the top notification bar.

Yeah but you still have unknown IMEI - that's something that should have not happened
Anyway, go to Preferred Network Type and try with Prefer 4G, Prefer 3G or Prefer 2G - maybe, with the updated Framework, something went wrong with the bands support or so
If it wouldn't help, then I'm out of the ideas how to solve
So I did do a hard reset now, and it worked for a short time (IMEI is back), then it doesn't again, and ... just now again. It really is not stable.
Thx. I will post updates when I know more.
Unfortunately the phone keeps crashing and rebooting when using it. It just freezes and restarts, and sometimes it takes a long time to restart (seems like a crash loop).
Twice I also saw some graphic artifacts (bright magenta and green) on a small part of the screen.
I don't think this is just a mobile network connection problem anymore.
BTW: I have installed an older version of Xiaomi Service Framework (also the hard reset reverted it to a much older version), but that did not help.
Hey!!
I hope you doing great
Did you manage to solve the issue?
@Fawad Hussain
Unfortunately I could not solve it, so I am not able to use the device anymore.
Btw, as far as I can see there is no current smartphone without a notch/punch hole which is not gigantic (ASUS Rog Phone 6).

Same thing happened to me, I have managed to get it thanks to this guy in the video which I don't understand what he is saying but I just followed his steps, so if you are looking for a solution this video is.
But my device is not rooted and bootloader is locked, I tried ways but don't know how to root it or unlock bootloader properly
