SIM Shuts down phone

I've had my Desire since it came out but a problem has just come up: the phone will shut down whenever the SIM card is inserted. Without it it'll work fine, but if i put it in, when it boots, as soon as it tries to connect to the network it'll shut down. I've tried a different SIM card and the problem is the same.
This started by using MIUI but i've clean installed a CM7 based rom and the problem is still there.
My phone is out of warranty so taking it in is not worth it.
Thanks

Did you try to flash a new radio.img?

No i havn't, i, rather stupidly, hadn't thought of that..... i guess i thought that when i flashed a new rom i'd get a new radio!

When you run RUU you get a new radio, but ordinary custom roms don't have that option.

I flashed the latest radio and the problem remains the same.........:crying:
Any other ideas?!

Then it's probably a hardware issue. You can try to disassemble it and try to fix connectors.

I'm now completly los now; the phone switches off with 3 different sim cards but not witha forth!!! I'll have the SIM card replaced even though it does work fine in my HTC ChaChaCha........
Very strange!
Thanks for your help anyway, it's obviously got to do with the card and not the phone so i guess the solutions been found!!

I have had the same problem, until yesterday. I'm running a cooked ICS ROM, and the issue has gone as soon as I have switched to a newer RIL. So don't take it for granted that it's a hardware issue or SIM-related. Hope this helps.

My help
you just have to activate the pin code on security and location setting
but the SIM card must be inserted to activate the pin code
If you never activate the pin code, then the default code is usually 0000
if the phone is turned off before you have to get to the temp setting reply me and i'll tell u what to do
If it worked for u don't forget to hit thanks

Mobile Network Not Available

Hey guys,
This may be a silly question, but I can't seem to find a solution.
I just flashed PAC-ROM 4.3 using CWM, and everything seems to be working great.
Than I realized I didn't have a mobile network signal, so I tried placing a call and it said "No mobile network detected".
How can I enable mobile network, cause it's not even in the settings no more?

I have the exact same problem, anyone with any kind of possible solution? Here's what I tried already:
1. Removed both battery/SIM for a minute or more then rebooted. (Also made sure that 2G was off)
2. Called a Koodo tech guy who updated the SIM.
3. Went in store to try and put my SIM in a different phone, SIM worked fine.
4. Lady tried installing a different SIM card (her own), still same problem. Tried a brand new one, still not working.
5. Backed up my pictures and factory reset the phone. Same problem.
6. Took SIM out, and the phone does recognize there is not a SIM card and now the phone gives me the NO SIM CARD message at unlock screen.
7. Updated to 4.3 - Nothing changes.
8. Browsed the internet for hours then cried myself to sleep, hoping someone would help me out eventually.

I had the same problem with revolt ROM. I flashed baseband and wiped all data but nothing changed...
I flash a factory image and it worked
Sorry for my bad english

[HELP] Sudden problem with both SIM Cards not being recognized on any ROM

Good day! I just want to ask if anyone has an idea of how to solve a weird and sudden problem that happened to my phone a few days ago.
I was running Cyanogenmod R16 with Xcelerate kernel.
I use two SIM cards on my phone, but I do not use the first slot all the time, so when I'm not using it, I regularly disable it through the SIM card settings, and enable it only when I need it.
What happened is, when I tried to enable it, suddenly both my SIM card slots could not be recognized (The SIM card settings could not be accessed; and error says: "SIM card info not available. Menu cannot be accessed"). In the lockscreen, it says: "INVALID CARD." for both SIMs.
I tried both restoring a backup and going back to stock MIUI, but still, the problem was there; none of the SIMs could be recognized (I tried using other SIM cards too.)
My IMEI's for both SIM slots are fine.
I've looked up on other forums, but I haven't found any others with a similar problem on the Redmi 1S.
If anyone knows what I need to do to fix this, I need your help. Thank you very much.

Have you tried both sim in other phone..?
If yes,and both working then should be problem with your imei!

Yes, I've tried both SIM's on another phone, and they work fine.
Since my phone still shows both IMEI's when I look for it, I assumed that there's no problem with them. What are possible problems that concern IMEI's? So that I can look up on general IMEI problems.
Thank you very much!

May be this can help friend

Thanks for the reference. Backed up my IMEI and Restored it right after, but still no change. Still, thanks!
EDIT: I've already tried two newly bought SIM cards, and the problem is still present.

Was this solved? Happening to me right now..

Happening to me too... Unsolved

For me just blowing in the sim slot & reboot fixed after few times..

if you have TWRP backup your modem & efs partition, just restore it via twrp. it worked for me

Hello,
I have a similar problem.
SIM2 is not recognized at all. I can use SIM1 only.
Tried to switch the SIM cards and still SIM2 is not recognized.
Both SIM cards are working great on other phones.
Is it OS related issue?

I've got same problem. Try to clean the sim metal contacts carefully and gently with an alcohol and qtip or tissue. It solved my problem.

Turn off your mobile and change sim slots then power on if problem still present then again exchange sim slots then power on do this 2to4 times i hope this will work.

No Sim help

Hello guys I've had this phone for a week. Now since it is a hand me down phone i cannot give you guys much details.
The phone is still unrooted, meaning to say there is no custom rom flashed here. When i got this phone it had some few issues like when you boot it up, apps will start giving you popup notice so I fixed it by factory reset and the next issue I've noticed was the systemui crashing but it turned out that the google app is the problem.
I've tried using different sim cards that are apprently working but there's still no luck. The owner that gave it to me said that everything here was fine.
I had to change the batteries since it's bloated. The sd card seems to be working fine. The only problem is the sim card reader. Not sure it it's a firmware or a hardware problem. I need advices. Thank you in advance.

Moto Z Play not showing VoLTE for specific JIO Sim

Hello Everyone,
I need some help regarding the network issues for Moto Z Play.
I started this thread because after doing a lot of solutions, resets and still it wasn't successful.
So here's the story -
Two days ago my brother gave me the phone which was in excellent condition (VoLTE working, Battery Performance, etc.) working on Android 7.0.
Then he did a reset on the phone from Settings so I can use it.
When I inserted my SIM Cards in the phone, I got network and everything and immediately I received an Update for Nougat 7.1.1. I installed the update and then when the phone booted, I did the setup and everything. But l wasn't able to get VoLTE on my phone. There was no Enhanced LTE Mode option in Settings. I thought it was something temporary and maybe after sometime I will be automatically resolved but it didn't.
The next day I started researching over the internet and found clearing the cache or data of settings or hard reset from recovery/settings will do and I did it but none of the solutions worked. Then I thought it was the SIM problem but it wasn't. I inserted the same Jio SIM from my phone into another VoLTE phone and it was working. I also tried another Jio SIM in Moto and it was showing VoLTE and everything was working perfect. Also I inserted my idea SIM (which was in SIM2 slot) in SIM 1 and it was not showing even 4G range (Just 3G) (The idea SIM is also 4G).
I tried everything - Swapping SIM cards, resetting the phone, Clearing cache, etc. I don't know why this has happened as my brother was using the same carrier sim in same slots (SIM1 - Jio|SIM2- Idea).
I also called the JIO care and they took the complaint and they told me they would look forward to it in 48 hours.
Also, my bootloader is locked and can I flash original stock firmware? (I guess that's only thing left I haven't tried) If so, please provide the link and guide to flash the firmware.
If Anyone has a solution please help me, I am in big trouble.

Get a new sim card for your number. Don't ask why. But this will work, trust me.

Thanks man, I was too thinking of that and went to JIO store. They had a server error and will be back available in 4-5 days. Will then post with new SIM results.
