The only one thing that I disappoint to my Z is the phone will be restart after I remove a simcard.
In iOS device, you can removing Simcard without restart the phone inorder to refresh the cellular network. Do you have any solove soulution for fixing this boring issue..
Another thing is low and cheap quality of Simcard tray. It is a vely ultraslim plastic, I'm afaid it will be disappaered when I sneeze.

Not sure why you would want to do this.
I think if you turn on flight mode and off again it would also refresh the signal.
Kind regards, Stefan.
It's not ios..... android need to reboot to get in the un/sim mode. (To make the sim data removed from the phone the phone needs to reboot)
Xperia s,z reboots / htc one, 1x reboots / samsung you need to shut the phone before removing the sim
Your phone is fine there is nothing wrong with it
Hit the thanks button if I helped

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.
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.

well simcard is 100% working, nothing to do with the simcard dirty or damage.
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.

Flash full stock ftf and try again
I tried but it didn't help. Any other suggestions
guys please help me out with this, it is very irritating
Try to keep your phone in 2g only mode. When i keep 3g only only mode i sometimes can't receive call from other party. But 2g only mode solved my problem....
Sent from my C6602 using xda app-developers app
How do I shift it to 2g mode?
menu->settings->more..->cellular network->network mode-> Only GSM
PS. type: *#*#4636#*#* and check in "phone info"
signal strength
GSM service(if enabled)
In old galaxy spica I had similar problem and I had disabled GSM(dunno why) and after second full flash of fresh stock ROM It was working again.
its not helping
I tried everything possible.
So maybe we start from beginning...
Few quick question before we can help you:
1. When those problem started?
2. After what? did you flash custom rom or Kernel ?
3. You had any app/script that could modify your phone?
4. You had ANY hardware problem before?
5. Your phone fall to the ground?
6. Did it have any contact with water?
7. What system do you have now.
8. did you check sim slot?
9. do you have signal strength in this menu that i post earlier?
1. This problem started a month back
2. It all started suddenly, I am on the stock rom without root
3. No I dont have any app that can modify my phone
4. Yes I had a faulty battery problem which was fixed
5. NYes once it had but it was a long time back before the problem started.
6. No it did not have contact with water
7 I use the stock android 4.4.4 kitkat
8 Yes I have checked my sim card slot, I have also replaced my sim a couple of times
9. Yes I have signal strength -79dbm and 25 asu
My sim works well with my other phones. Is it a hardware issue?
I think Im getting a clear view of the problem, my phone isnt able to shift from 3g to 2g I guess. I came to this place where only 2g works, I had my network mode setting as Wcdma(preffered)/gsm, its reluctant to shift. Is it a hardware problem?
Hmm.... If you have signal and phone see network its not hardware problem. To be honest its more like system or more specific kernel problem in 4.4.4 I say this because you ares sixth person who i know that have network problem in 4.4.4
For examle after flashing kk on my phone i have looooooots of reboots if i have 3g network on, and my phone swith to 2g if its in sleep mode.
My friend also have problem similar to yours but it cant use phone function if its have LTE enabled.
Best part is that when he flashed 4.3 problem is still there, but he didnt had it before when he had 4.3
I cant flash any other system now(i use phone too often )so i dont know if i also would had this problem...
So if you can, you could flash even 4.2/4.3 full clean rom and check, just to be sure. Its a bit "extream" downgrade but flashing it and checking its max 1h...
Probably like always its small weird bug or specific system setting problem, maybe different region rom...
So for now you could check other rom, even branded and downgrade to your old 4.3 to see if you still have such problem.
Seriously its a relif that its not a hardware problem yet.
I also flashed the lower version of the kernel. I am facing the same problem . I use the local region ROM only,
I think Im gonna give up on sony now
Hi there
You are not alone, I am also facing this issue and do not know how to resolve it too.
Sometimes when I try to call (full bars on) it makes a bipbip then Call not possible...
Same issue while switching from GSM to H... Most of the time I have to reboot and let it settle for a while.
I am suspecting my network provider
Sent from my C6603 using XDA Free mobile app
I called up the service provider, it seem to get fixed for a day but again the same problem continues
I'm tired of this, the phone guys can't do anything and neither can the service providers
Such an irritating bug by sony
Did anyone get a solution to this problem?
This is very annoying
Same problem,posible solution temporary.
I'm in spain,having a virtual operator sim called ono,is using vodafone infrastructure.Is needed to have roamin allways activated for data and call to work properly.When stucks to connect,i put in flight mode 1min.With orange sim no problems.With ono sim in a windows phone i had no problem.Now i demanded a sim 4g,will see if are changes.

Hi
I have been having issues with my Note8. It loses the cellular network periodically, and doesnt acquire it back. A reboot is required to get the network back but then doesnt last long. I have tried most everything. Listed in order
1. Reseating the Sim / Removing the SD card to check if that was an issue
2. Switching network from 4G to 3G to see if that was the issue
3. Factory reset a few times, including once while not installing apps and letting the phone run with less apps
4. Changing SIMs
5. Changing SIM tray with an S8
6. Using another network sim card
7. Running the phone in Safe mode.
I have exhausted everything that I can have done. Any other thoughts or suggestions?
Phone is within warranty so I can get it fixed, but the issue is that I live in a different country now and they will charge to just take a look at the phone.
Side effect is that while hunting for the network, the phone gets hot and runs down the battery.
I am hoping that there might be a software issue, as the phone does connect to the network for a while before losing connection.
Any help would be much appreciated.
Thanks a lot.
It looks like you have done all of the obvious stuff - it's starting to sound like a hardware fault to me.
Thanks! My worst fear unfortunately.
Was hoping someone might have a software solution or something else which I could try but...
i had same problem with 2 x galaxy s8
after they test for a month and big fighting with those F customer care
they replaced 1 with sealed box and the other one they changed the motherboard which doesn't help , still same problem
i sold both

Hello guys. I bought a s21 ultra 9980 512gb.
However, i cant use it with sim card as its not detecting the network. I dont get it what could be the problem. I cant even untick the automatic network search as i get error.
Will post you guys here some photos maybe you can help me out. I dont think is locked because i dont get any message when i insert sim to enter the unlock code. What could be the problem?
Please help. Thx
Are you sure its an active sim card?
Yes. I have the card in an iphone as its my current sim..

Is the Samsung running official FW?
Yes… original .
do you still have the imei number present in the settings and if you type *#06# ?
Might be sim locked by the carrier, you could theoretically still use the esim I believe if it isn't giving you an option to enter an unlock code.
Yes.. both imei show up.
How can i check for sure its sim locked?
Also, when i insert any sim, for one second the “no signal sign” near the battery goes away then comes back instant.. and it doesnt ask for any pin…
Thanks for your inputs
I have read about this issue before as well. Is this a "dual sim" model? Try the other slot if it is, and also try leaving the sim in and rebooting. You could also try "reset network settings" under settings. I'll have a look to see if I can find the thread where people said they had a fix.
is it yours from brand new? and have you checked to see if it black listed? also, there seems to be an issue with some Samsung where they are forced into airplane mode the only way you see this is the notification panel the airplane model toggle is half-lit blue I could be something to do with that. Failing that it could also be if you have dropped the device the ribbon may have come loose as this is a common issue with Samsung a range and that's all I'm seeming to fix lately
Hello. No, didnt buy new. I got it used.Yes its dual sim model. It doesnt appear as blacklisted.
Its not in airplane mode for sure. Also i did factory reset and also wrote all stock firmware ap cm bl csc from samfirmware..but its the same as before.
Also, esim doesnt show up under the sim card manager.
try *#2263#* to change bands, or *#0011#
Maybe also try to put the sim in the other slot, and see what happens. If all the same, try someone elses SIM card for a minute to see. Maybe your sim has become slightly damaged but your iphone still manages to read it, while for some reason the s21 is not managing.
Just tried the sim in my sisters s20 and works. Also tried her sim into this new phone and same . Even if i put in sim1 or sim2.

"In Settings go to network mode and set this to 3G only. Then restart your phone. This works in my case."
Thanks for your sugestion. But its the same…
I had the same issue on single sim korean unit...but factory reset resolved the issue. Actually i used to disable carrier apps which was causing this issue.
