[Q] [Help]C annot find SIM card 1 of i9502.

Dear all,
I hv got an i9502, but the SIM card slot 1 is always showing "no SIM card" whatever I put different SIM cards.
But I am going to use it in HK, is it caused by the chinaunicom network lock. Is anybody using the other wcdma card except chinaunicom?
If it s caused by network lock, any method to unlock the network lock?
Thanks.

I think if locked, it should be both... I9502 from China unicom should be unlocked

I have similar issue. My i9502 suddenly have sim card 1 locked. When I go to <Settings> <More> <Security> <Set up SIM card lock>, it is found SIM1 is locked.
I tried to tick and unlock it, but it says "0 attempts left" and as a result, I cannot unlock SIM Card 1.
Now, I can only use SIM Card 2 on my i9502.
I have tried to refresh the firmware and the result is the same, i.e. SIM 1 is still locked and cannot be used.
Any hint to solve it!!!
Million thanks in advance.

I met same problem since this morning. have you got solution yet?

[Q] [L3] [cm9 nightly] no APN, no PIN number asked, no data

Hello, i have an Lg L3 e400 phone with the latest version of cm9 nightly which worked fine with my old sim card.
But with the new sim card of my new carrier, I have few problems :
PIN number is not asked at startup so I disabled sim card PIN lock.
I do not have APN, and cannot add one : it's not there after I saved it.
The menu set up SIM lock is greyed.
When I install stock rom, the sim card is correctly detected and everything is working fine.
Thank you for your help.
Léonard.

Problem: SIM card message is full

Hi there,
i'm expericening this issue , even when i had Oneplus 3.
i'm now having oneplus5 and it still happening.
basically, somehow, SMS messages are going to the SMS app AND to the sim card itself.
when the sim card is full , i'm getting notification that it is full, and cannot receive any other until i delete them.
where can i remove this option to save it to SIM card?
i tried to change cellular carier, done Factory Reset, changed rom and kernel.. nothing helps!
other software that i use is "super backup" from google play store, in order to backup SMS's.
help please!

Problem data connection

I have two issues.
When i flash new Rom, If I do not remove the sim card, I have a bootloop.
The other problem is that I do not have data connection.
The list of connections appears in APN but none activated. If any, I still do not get data connection.
My company is Orange from Spain.

Have you tried format data and flash?

No sim detected

Does anybody know why my sim card is not detected after restart? I'm on a11 b2,rooted. And I cant enter mobile data settings at all. When I try to enter mobile data settings just a black screen and after that com.android.phone has stopped working

Obvious question, but have you tried removing the SIM card and cleaning the contacts?

Of course,this only happens when I restart phone. I dont think that contacs needs cleaning after that. But thx for answer. I have to dirty flash rom after every restart...it's not very practical ?
