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

Hi,
I recently installed CM11 (final official snapshot) to my stock rom slot (I had it on rom slot 1 before, but changed to stock because it is a lot faster). Everything seems to work, but the SIM is not recognized anymore. Calls, SMS and Data (2G and 3G, since I am in Europe, 4G does not work anyways) work fine.
The lockscreen says "No SIM Card, Emergency calls only" (or something like this, I am translating this). The signal strength is always reported as 0% or -120 dBm, even though the signal is fine.
When I go to Phone Status, it tells me that my phone number, MIN, PRL-Version and Serial Number are unknown.
Network Cell Info Lite tells me that "SIM Status" is unknown and that it can't read any info from the SIM, but connectivity is fine.
On the old installation everything was fine.
I tried all the usual things (rebooting, reinserting the SIM, ...)
Does anyone know what could be the cause?
Edit: SMS is not working. And a factory reset did not help.

you installed over the stock rom on the stock slot instead of another slot am I correct. Also witch version of ss are you using.
Ok, I finally had some time to test a bit more. I am using Safestrap 3.75. The problem also exists if I install the ROM (tested with the newest two official snapshots) to a clean regular ROM-slot (I used slot 2). It does not exist, when I load the old installation that I have on slot 1, which is based on some old version from mid-2014. So it does not seem to have anything to do with the slot or the phone. I will be trying other versions.
Flashed the last version of CM 13 NIGHTLY into my Moto G and the SIM isn't working properly, it asks me for the code to unlock the SIM Card but I get "No Service", everything else works as expected.
The IMEI seems to be fine.
When I "jump" into the "*#*#4636#*#*" I can't turn on the Radio, neither change to GSM or anyting else since it goes back after reopening.
Tried:
- Flashing with different versions of TWRP.
- Flashed stock ROM and the 6.0.
From the research I did I think I need to flash a modem firmware with the Radio(which I can't find) or a new Kernel - need advise on this one.
Thanks.
Closed per OP request.
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.
Hello everyone!
I am new to custom ROM flashing. I got a Samsung Note 8 N950N (korean model - I guess) - but it shows N950F in Settings app. I got a used phone from someone, and they had installed some custom ROM on it.
Now, I flashed LineageOS 17.1 on it, everything is working smoothly so far but my mobile network isn't working. I can't make or receive calls. The phone is showing "Emergency Calls Only" - but showing the network name, and I can also access the SIM card toolkit inside the phone.
I tried clearing cache and everything but can't seem to make it work. I tried using the manual cellular search, but it says couldn't find any network.
It is a dual sim phone, I had 2 IMEI appearing on earlier ROM, but now with LineageOS 17.1 - I am only getting 1 IMEI as well.
Update: I restored to the OLD ROM (LamLazy Rom v3 Dual SIM) - and the network is now working back on the phone. I don't know why it wasn't working on LineageOS 17.1, can someone please help?
Did you manage to get a custom working with cell service too?
