My Polaris is not detecting Sim Card. I have tried:
a. Changing Sim Card.
b. Flashing to official Rom and Radio.
c. Cleaned the connector itself.
Can someone suggest some possible solution for this issue......!!!
Same Problem Here
Mustking, I have the same problem although not as bad as yours. I believe it is the SIM card reader. Mine works 98% of the time and every now and then just goes offline. It then comes up with SIMcard not found.
See my post here... http://forum.xda-developers.com/showthread.php?p=3980181#post3980181
If you find a solution I am all ears!
I had the same problem where it wasn't working at all not recognising all sims i had to send it back to HTC they replaced something and the main Mobo

Message: "SIM card missing" after dismantling
I dismantled my Polaris yesterday. Since I did it, it says "SIM card missing". I'm sure the SIM connector that plugs into the motherboard is well attached, but there's is not way for it to get the SIM card. I soft-reseted it lots of times because somebody told it could be the solution (after taking apart Polaris into pieces).
I don't know what to do. Looking into the forums somebody also said that some "EMI gasket" is vital for it to work, but I don't remember having removed it

you should try to clean the SIM connector on your device with an easy dry cleaning fluid
i bought a t959v with cracked screen for main board. i have a new lcd replacment screen. when i put it together and turn it on i try to make a call it says not registered on network also not seeing any internet signal but is showing full 4 bars for reception .when i hit software update it says DM initialization not ready check nrtwork or sim card. i know sim card is good because i just took it from another t959v. is there a way to check reader . thinking it might be bad.called t mobile and had phone registered. is it easy to swap out sim reader. thanks. ps i swaped a main board out like this once before and it conected with no problem
try reseating the simcard part (requires unscrewing and removing the back). While the part is removed, check all the pins to make sure they are connected right.
Hi there!
So i got a NEXUS 5 32GB.
Short story: i had an old SIM card, like 5-10 year old, when i bought the phone. I cut the card into microsim, and worked like a charm. (You know, nexus stuff when no service sometimes like once in a week (restart solved always the problem)). Now i contracted with a new service provider, and the (3in1) micro sim i get is unreadable to the phone.
Detials:
-The new card working in other phones without problem.
-I went to my carrier and get a new sim card, doesnt work either. (so the sim card(s) not defected)
-Tried different SIM cards in my phone-> working only the old SIM cards, new micro sims doesnt
-Tried almost every softwere stuff, (factory reset, FR in recovery mode, flashing 4.4 android, flashing other androids, flashed radio files etc.etc) ->non of them worked.
-We disassembled the phone, the sim reader is looking perfect, not a scratch, all pins in order etc.
-THE MAIN problem: however i insert the new card(s), phone says only "No sim card, emergency call only". Can't even set up the mobile services, nothing. Only can turn on-off the NFC, Airplane mode etc.
-When inserting the old cutted card, works perfectly.
I'm paying now for 2month for the new card, but can't use it....
Please help me!!!
Any kind of help will be appreciated.
Thank you very much.
Have a nice day.
PS.: Sorry for my english, i'm from Hungary.

edit:
flashed several different custom roms and they work all fine except the sim card will not registered. still it seems there is a difference if a sim card is insert or not. in settings, about phone, sim status 1 or 2 everything is marked as not available, if no sim card is insert, this menu isn´t opening at all. when i try to make a call it just says no sim or sim error. has anyone an idea what i can do or what went wrong? an helpful information could be that i´m using a german sim, this explains also why my english is that terrific. would be glad about some useful hints.
Hey, is anyone else experiencing this problem? I believe it is a software problem as I just bought the POCO X3 NFC and the SIM was working fine, but when I rebooted the phone, it didn't detect any SIM card. It still detected the SD card though. After rebooting several times and taking the SIM tray in and out several times, the phone suddenly detected the SIM and everything worked fine. The next day I reinstalled MIUI 12, thinking that it may just be a bug as it seems it is a software problem, but upon rebooting the phone the same thing happened. I attempted rebooting and taking the SIM tray out multiple times, this time with no luck. I took out my SD card and put the SIM in that part of the tray and it now works more consistently, but still will not always detect the SIM after reboot and I must reboot and take the tray out until it works. Also I can't put the SD card in now. Any ideas?
What makes you think that it's a software related problem? I don't think there's much software behind simply detecting a sim card and you already said that changing to the second sim tray has helped a bit. I'd RMA that phone if I was you
Because it only happened when rebooting, once it detected it, there where no problems. If it was a hardware problem, it would probably have not detected aside from just rebooting right?
I'm facing ditto same problem bro can anyone gemme solution please
