Not able to read sim card

My phone works normally, then, after performing a factory reset, it won't recognize the sim card anymore. If you go to the setting, and try to access the menu where you can set the desired network, everything is not highlighted. That means all menus on that page cannot ne be accessed. Anybody can help? Thank you.

Try a different SIM to see if the issue is serious or a setting problem. Sometimes you can lose your carrier APN settings and have to add it back in.
Does it still show it's EIME numbers in settings? Is it dual SIM or single? Check if anything in Dev options has caused it.

My Huawei Ascend Mate 7 is not a dual sims. It only 16 gb version. In the setting, if I click: All-->more-->mobile network-->(the mobile network setting page menus are all not highlighted or not accessible). Yes, I tried a different simm card, and I went to T-Mobile, the guy told me, she cannot do anything since the menu setting page cannot be accessed. If I type *#06# on the dialer pad, yes the IMEI number will show. This problem accoured after performing a factory reset. Thank you.

if this issue come after factory reset,and if you sure sim card have not any problem,and if you Didn't Flash another firmware on your phone...I suggest find an official firmware Exactly for your model(mt7-tl09) and your reigon(middle east/Europe/Africa/Spain or...) and Flash it on your phone.
it's the best and easyest Way to solve it.
*the comform of firmware model and Reigon with the phone,is very important for working Simcards correctly.
*if nothing change After flash a new firmware,it's surely a Hardware problem.

Yes, I agree with that.
Look in the settings for which stock ROM it's running.
Is it rooted, custom recovery etc?
Needs stock recovery to do ROM update. Root doesn't matter but easy to un-root anyway.

No service in European L09 C432 ROM issue

Hello everyone, i know that here collected the best minds of Huawei custom thing development
So i have a question to you, and i hope that you can help me, i dont know there to search and what to do
Originally i had a Mate 9 with L09 C432 ROM (UK Three mobile), after time i decide to flash custom rom, to get a better battery life, root and another tools
Because my phone is insured i have to bring this to original ROM one day, but.... Now when i am flashing any version of L09 C432 ROM i dont have network access (cannot use mobile data), cannot make calls and messages, but i can receive calls and messages. In row about phone i have MEID 0000000000. In top left corner there should be carrier written - No service, looks like that phone think that he is now 2 sim model
No service
One ROM from L09 which one is working for me is RomAur 1.5
I tried to rebrand to another model, and after back to original, not working, all possible roms - same issue. I dont know which part of ROM responsible for receiving calls and messages, or what i destroyed in my phone
Any idea for this?

Hello.
I'm not a developer or something likewise, I'm just a regular user. I have a mate 9 bought in latin America (Dominican Republic) after a month I rebranded my phone from MHA-L09C25B106 to MHA-L09C432B182. My phone was built with a single SIM and when I installed the ROM from this post. https://youtu.be/8OywEYZ2cbw it also gave me the MEID 00000000000000 but it let me do call and use data, also I noticed that even if the ROM was for MHA-L09 it has two SIM toolkits, one with the name of my carrier and the other with none but the phone was fine. The problem came after I updated to B190. I had the no service massage even though I had my SIM card inside, what I did was while on I took off and back on the SIM card and the service came back on, I restarted and came with the same thing so I took it off and back on again and my service came back. Because I use a case I don't want to be taking it off plus doing the same with the SIM card so I reinstalled back the MHA-L09C432B182 and don't allow the system to update itself.
I recommend for you check your version if it is ...B190 and also do the SIM off and back on solution.
Hope this helps.

Yep I have to eject and reinsert the SIM. Rebranded from L09C185 to L09C432B190. (SINGLE SIM)
Any fix for this on B194?
Will I have the same issue if I rebrand back to L09C185?

Huawei Shotx ath-ul01 sim problem.

hi reader. its been almost 1 month since i bought a second-hand Huawei Shotx ath-ul01. when i bought, it was on android 5.1.1, EMUI 3.1. and update was pending for android 6.0 . On first 5 to 6 tries it did not update and ended with error. and when it finally updated successfully it was unable to read both sim cards. and after rollback it even got worst . now when ever i insert a sim card it asks for PUK code and doesn't even accept the real PUK code for my SIM card. i have also tried changing SIM card but the problem is same wit every SIM. Please some one help me through this. i'll be very thank full.
HOPE TO HEAR BACK FROM YOU SOON!

Has the device been rooted ever before?
If you have not any better idea, try to perform a factory reset(wipe data) + wipe cache partition after a full backup. Good luck to you.

system related commands work like a charm.

Hi guys,
I got my 20x today. I want to know where I can get a foreign sim card to update it to android 10. I live in USA btw. I think I need a chinese sim to update it to 10.. but not sure. Or if you know of other means of updating it let me know. Would appreciate it.

Hi TAJ_Rocks,
I did as you suggested... I checked for updates in hicare. It says I'm up to date and I didnt get any notifications. Then I changed the country to china in the hicare app and checked for updates that way. It still says I'm up to date. Is this the right way of doing it per your instructions? What do you suggest?

I'm in CA, using AT&T and T-Mobile SIMs (see upper left corner of attached pic). Didn't have to do anything, got the update via OTA.

I am not in the same situation, and I don't understand why the update doesn't just get updated from settings=>system &updates=>software update.
I remember having some problem with moving to ten though. I messaged huawei a polite query through one of their apps. Probably Hicare. They didn't respond, but within 36 hours an automatic update came through... coincidence? Not sure, but worth a try rather than try to procure an OS Sim... don't think that sounds too legit in this day and age.

I reached out to hicare and the rep said my device belongs to Singapore. But sadly there are international limitations. She said updates are released depending on region and so foreign devices might not receive the update on time or won't receive it at all. She suggested I try to update my 20x using HiSuite. She also recommended I talk to huawei customer care in singapore. She provided the weblink to them.
When you called hicare did you chat with a rep? How did you communicate this to huawei that resulted in a solution?
What do you suggest?

Unfortunately this doesnt work. I changed language to chinese and singapore in hi care. No update.
Huawei in singapore emailed saying since my device is made in singapore that the only way to update is to use a sim from singapore and be in the singapore area which is ridiculous.
I've looked at sim cards on amazon and ebay. Apart from the cost theyre shipping times call for delivery in June which again is ridiculous. Do you know of a way to get a singapore sim card soon in USA?

It has nothing to do with simcard just factory reset or install by pc hi suite

Hi TAJ_Rocks,
Thanks for the followup. Its been factory reset since I got the used phone last week from ebay already reset. I already installed hisuite and am still unable to update that way.
So I think the 2 other options are dload method and sim card from singapore.
But if I use the sim card option to update to 10, will huawei send security updates afterwards?

First of I dont think simcard is needed for update. Even if u bought and get update. Afterwards ull receive updates automatically no need for simcard again.

Hey TAJ_Rocks,
Yeah thanks for that. Someone on another one of my threads said the same thing. I plan to use the dload method to install 10 on my phone. The thing is, I need an Adapter Cable Type C to USB A. I ordered it and am awaiting delivery to use in the dload method. Hopefully it shows up this week fingers crossed. Thank for your help and replies!
.

Problem now is DLOAD method only works if we have the firmware for our model EVR-L29 and region code C636 for example.
But I cannot find them. So now what?
