My Tytn is in great shape(normaly) without SIM and jut to be shure i took the memory card out to. But soon as I insert the SIM the display just stucks. Can't use any buttons, can't use touch display, it just stays like that with dimed display.

I think you have problems SIM Issue door ...! you'd better release the SIM card first then try a soft reset your device ....
after the soft reset you can replace the SIM card and the device operates properly

I did soft restart I even reinstalled the rom but still...
Shud i go to my provider and ask for a new SIM or i some kind of mechanical problem with the door?

Some thing wrong whit the z1?

anybody have the same problem?

Go via Warranty.

Well same happened to me at first I though was the sim reader but it was the rom that suddenly stop reading the sim and I don't know why. The solution was to flash a different rom and now I am with kitslim. To check the sim reader I used the app "sim card by gsmdev" such app allows to read the sim information like contacts imei etc so if that app reads that info means that the sim reader is OK and you need to flash a different rom or the same. Hope this help

check "network mode" in "mobile network settings" .....

Check if your imei is intact, perhaps you could flash an FTF file which will replace the OS so back everything up first.
Make sure you are inserting the sim correctly (i know you probably are but it's worth checking) ones the sims in the phone it should reboot, could be that the contacts which hold the sim aren't raised enough, don't bother fixing them just take it back if that's the case, if the sim has been inserted incorrectly then theres a chance that the contacts may be bent and if that's the case then your warranty will be void, but in all fairness it sounds like a dodgy phone rather than any of the above.
I'd still do the FTF flash anyway, it's probably the best shot you've got, oh and i've noticed that some peoples phones will read sims and others won't so the fact that it works in yours and not hers although weird, isn't conclusive. Try another sim too.

[Q] No network issue LG Optimus 4x HD

Hi guys,
I have a LG Optimus 4x HD with stock rom (Jelly bean). About three weeks ago, I suddenly lost my network connection and it looked like my phone didn't recognize my SIM card. I put my battery and my Sim out and in my phone, but that didn't help. I tried many SIM cards and they work excellent on my other phone. When I turn my device on It just boots up and doesn't ask for my pin code at all. I see no difference when my SIM card is in or out my device. However, it does recognize my SD card, so I think there is a problem with the software? On the lock screen I just see the message ''no service'' and at the top I see this (first pic). When I try to dial someone it says ''reorganization of internal processes. Try it later.''. I read on a forum that I had to go to ''mobile networks'' in settings, but that isn't possible (pic 2).I also tried to put some paper between my sim card and my sim card slot but that didn't work either. Does someone have this problem too or is there somebody who can help me to solve this problem? Your help would be greatly appreciated.

I discovered that my phone doesn't have an IMEI and IMEI SV code anymore. It also doesn't have an baseband version. Do you guys know this caused the lost of my network connection and does anyone know how I can recover my IMEI number? Finally I managed to enter the mobile networks in settings by do a long tap on the data icon in the notification center. I hope someone can help me.

I have the same problem as you. With every restart the phone is unable to read the sim card. Also the baseband is shown as unknown, and I don't have imei no. The solution for me is to remove the battery, and put the phone in the refrigerator for 10 minutes.(yes in the refrigerator The phone is getting very hot when is searching for network and to have it really cool helps apparently. Try it yourself to see if it does the job for you and let us know.

Thanks for your reply! This morning, my phone finally asked for the first time for the sim password and I finally got a signal. I got my IMEI and my baseband number back. Unfortunately, after an hour or so I tried to send a sms and I wasn't able to send it. I got the error no USIM or so. The IMEI and Baseband number disappeared agian. I turned flightmode on and of and I didn't get a signal again... New today was that I am now unable to connect to multiple wifi networks too. Now my WI-FI MAC-adress is 00:00:00:00:00:00. I already lost the phone and I now also lost the smart part of my smartphone... I also tried to put my phone in the refrigerator but sadly it didn't help. I think I have to buy a new phone....

Sorry to say that "It's time to say goodbye"
I got same problem with you and try all kind of possibility. Here is final verdicts:
- Some phone repairers I know said It's the encrypted baseband partition is damaged, unless you have backup of that, it's a no-go
- I've tried to reflash the phone and it will stuck at 10%, you have to push really hard at some point at the back to make is flashable. After that, the signal back on with baseband and IMEI.... but only for a few restarts it will be gone

Hi blbterminator,
I already said goodbye to my p880 (has been replaced for the G3), but thanks for your reply. Now it's clear for me that's it's a hardware issue.
Maybe do you know if this problem only affects the lg p880 or other brands or models too?
Many thanks!

My p30 pro VOG-L04 doesn't detect the sim car

Hi, fisrt of all I'm sorry if this is not the right site for this thread, I have a P30 pro VOG-L04 that doesn't detect any sim card, I hope someone can help me to solve this issue, I just bought the phone, the person that sell me the phone already told me from that issue, I already checked the sim board and eveything looks good, thank's in advance.

If the device isn't SIM locked then I suggest you check wether the SIM card is properly touching the gold part on the board. You can add some tape to the top of the SIM to make it bulkier. Good luck

Hi, thanks for the help, I already change the sim reader, but nothing happened, a friend of mine tell me that maybe the modem gone wrong, and that's why the phone don't detect the sim any idea how to repair the modem??

Hi friends, sorry to ask but, did someone have the p30 pro schematics? Or the repair manual, I want to see the movil network diagram, maybe I can repair my phone

i know im late but i had this problem for two days after coming back from vacation from a humid place. it seems that the sim board needed reconnecting. what i did (lil technical background) is i opened the back with a heat gun and unscrewed the bottom right part on the phone where the sim tray is and disconnected and reconnected all the wiring on that section. Shame i didnt do this before i formatted the phone before but i hope this helps someone else coz now everything is working as usual. (nothing needs to be removed, just the connections need to be disconnected and reconnected)

Question Mi 11 ultra isn't getting phone signal

Hey everyone. I bought a Mi 11 Ultra from china but I don't know why isn't getting signal at all. It detects the SIM but it doesn't let me make or receive calls neither messages, and obviously it doesn't connect to mobile networks. Can somebody help please?

Where are you, what network are you trying to use and have you got some screenshots of your network and SIM settings?

Hey, thanks for answering! Im in Mexico and about the network, any of them. I thought of changing the ROM from the CN to the global one to see if that help, but I need the mobile data to unlock the bootloader, and since the phone isn't getting signal, I cant do that.
P. S. Sorry, what do you mean by SIM settings?

Attached are screenshot of my SIM settings. Yours will be similar. Make sure your apn is set correctly. Make sure your SIM is recognised. Just basic setting checks. May be try other sim slot and of course, make sure it's right way up for either slot.
Without any screenshot I cannot see what may be wrong, so start again with SIM. Shiny side outwards and make sure it is recognised.

Hi again. Yeah, I have tried with both slots for the Sim, each one the correct way, but is the same result for both of them. Thanks for the example of the SIM settings, now I attach mine. As you may see, the SIM is getting recognized, just don't know why isn't getting signal. I've also tried with other company's SIMs, but I get no different result.

Looks good. I think you need to try with another SIM on different network and same. Try this SIM in different phone as it looks all good on screenshot but may be provider has not enabled it properly. If different network SIM known to be working doesn't work in your it must be hardware, hopefully not .

Also look at settings, all specs. Check SIM status and press 5 times on memory for deep phone info.

Hello and thank you again! Yeah... I've tried different SIM from different companys, all of them known to be working, but none of them has worked on this phone. I'm starting to lose hope... But here are the other settings, just to make sure isn't about software

The screenshot show that your radio is off. This is saying that your phone SIM is not turned on for some reason.
There is not much anyone remotely can do, if you are unable to get it turned on.
Maybe someone else has an idea? If not, and it cannot be resolved by resetting the mobile network ( in settings somewhere) or phone reset, then it may be back to seller as a hardware fault. Sorry I can't help. Let's hope someone else can?

Thanks a lot for your effort. Since you told me that the problem could be the hardware, I asked the seller about this issue and he told me that this problem is covered by the warranty, so I'll send the phone back to them. Again thanks a lot for answering!!

Just for info have you seen this thread about att? https://forum.xda-developers.com/t/not-a-recognized-device-by-att.4462649/#post-87088003

No, I hadn't heard about that, but still, I wouldn't hesitate on changing my provider if another one works, but since I tried changing to another provider SIM and nothing happened, I guess it was a hardware problem. Thanks a lot for the info!

Try doing manual search of network. If it shows nothing then try checking network frequencies of your network provider and comparing them with this phone supported frequencies. Sometimes its due to your network provider doesn't operate the frequency which this phone supports.

thats an easy fix, modem partition needs to be reflashed and configured via code
