Hi All. I have quite a strange case of my SIM card not being recognised by my Xiaomi Mi3W.
Here's what happed.
1) Purchased phone off friend with stock MIUI - all working
2) Inserted my SIM with mobile carrier A (still with stock MIUI) - all working
3) Flashed Cyanogenmod 12.1 Cancro on phone - all working
4) 3 days later, changed mobile carrier to carrier B - not working
Original SIM card from carrier A was in phone when my account with carrier A was erased.
Since my number was ported from carrier A to carrier B, the phone has had issues recognising SIM cards.
5) SIM card from carrier B not working, and neither are other SIM cards
6) I have checked with carrier B and my phone is definitely compatible with their network.
7) My SIM card is working on all other phones
8) The weird bit is that at the shop of carrier B, the shop assistant SIM worked, but a brand new SIM didn't.
9) I have tried reflashing Cyanogenmod. - not working
10) I have updated Cyanogenmod. - not working
11) SIM tray looks clear of dust/obstacles - still not working

Not to sure where to go to next. I guess I can try back to MIUI or stock android, but I'd love to hear what you think.
Try doing a factory reset (assuming you haven't as mentioned in post)
If still not working, remove the sim, flash the stock miui back through fastboot, guides of which can be found in more detail in the miui forums
See if the sim works or not, if it does try rooting and installing recovery
Then flash the cyanogenmod and see if the issue still persists

Every time I flash a new ROM, the SIM is corrupted and I can't connect to AT&T.
SIM card was out before and during flash.
USB disconnected during flash.
The APN Settings are fine.
I even put a good, working SIM card (from another phone) in the device and I got service. I also put the bad SIM in the other phone and it ALSO got no service.
The APN settings are equal on both phones.
I had to go to AT&T and get a new SIM activated. I do not want to do this every time I flash a new ROM.

Bad luck. There is no way your phone picks and chooses what sim card to mess up after flashing (you said it corrupted your sim card, but not another one you tried?), and if it does you need to find a new phone

It did this on two different phones with two different roms (Darky 8 and Pheonix 2.5).

This is just highly unlikely, especially if you did everything you claimed to do (removing the sim card, unplugged during flashing, etc)
Hi, I have xt1079 for about 6 months, and it works well, since the day I used it in low coverage area,
it has Mokee 5.1 build and works in LTE network. And I take the 2nd sim card off while the phone was working, and after that the phone cant recognize the 2nd sim card at all, after a half of hour the 1st sim card lost too.
After rebooting the phone show phone app error...as I can see, in settings menu IMEI information became "unknown".
I wiped the phone and try to reflash the same firmware, but the result was the same. I tried 6.1 firmware, and the IMEI information came back and the phone works , but only in 2g. I mean I set the LTE/ 3G/2G, but it always in 2g network.
If I install LTE only or 3g only - no signal.
If I flash the phone back to any 5.1 ROM it's loose sim cards.
What would you recomend? Flash stock firmware?
I don't do it yet, what do I need to flash stock firmware?
Download the stock firmware for XT1079 and flash it from PC using fastboot. All the process & steps to flash are already available on XDA, just give it a search.
Hey there. Around a week ago my S5 Mini suddenly can´t detect my SIM anymore. It just happened from one day to another without doing anything unusual.
"Insert Sim Card.
Insert SIM card to access network services", is the error I get. (Had Android 6.0.1 back then)
I feel like I´ve looked through everything Google offered.
I already did the following:
- Put my SIM into another Phone. It works there.
- Tried another SIM in my S5 Mini. Doesn´t work.
- Ordered a new SIM Card
- Updated to newest firmware.
- Factory reset
- Opened my phone and replaced the Sim/SD Card tray with a new one I bought online.
- Flashed 6.0.1 via Odin
- Flashed 4.4.2 twice
- Checked IMEI via *#06#, all fine
- and other stuff. (Airplane mode etc)
It´s really strange. The phone worked for over 2 years quite fine. Now a month after the warranty expires I experience this problem.
The device is not rooted. But in order to repair it I would root it.
Hope I can find some help here
Hi,
Stock XT1803 phone and stock rom - Android 8.1 latest updates etc
Sim card inserted and registered to network, but no signal bars.
Radio reported as off - have reflashed the modem as per a guide in here - no change
when turning on `automatically select network` the device reports registered which i find strange
sim works fine in another phone, an alternate sim performs the same strangeness in this phone
Have reset to factory.
Any assistance gratefully accepted
So i bought a new note 10. On the box there is a sticker over the second imei nr and the sim card tray has been modified to only allow one sim. However on the back of the phone it clearly has a sticker showing both imei nrs. I suspect the phone company install a custom rom that disables the second imei as doing the #*06# trick only shows one imei.. any advice how to get my second sim working?

I got my phone from Vodacom also single SIM. The ROM is not custom, it's simply a different kernel that is used on the single SIM variant. To enable the dual SIM the kernel needs to be replaced with the Global/international version that has dual SIM enabled.
The solution to this is relatively simple and I can explain it to you in detail.
Disclaimer: You should already have some experience installing custom ROMs to do this, but if you are a noob don't panic, it not as involved as a Samsung.
First step is a bootloader unlock. Tools required is a pc/laptop and Xiaomi MiUnlock tool. There is a detailed how-to here on the forum. Make sure Find my device service is disabled. This process will reset the phone and you will lose all your data on the phone and it takes 7 days during which time you can use your phone normally just do not power it down or restart it. The phone reset only occurs when the bootloader is unlocked after 7 days. Take this time to back up anything that can't be saved by your Google or MiAccount.
Second step, install TWRP and flash the latest stable Xiaomi.eu build for our device. Dual SIM enabled, enjoy.
Last there is 2 ways to install the 2nd SIM card. 1. craft knife surgery on the SIM tray or wait for one from eBay or Alibaba.com.
Read the Xiaomi.eu thread for more info and a more detailed guide to flash the firmware.
