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.

I just got a used AT&T Vivid with what turns out are 2 anomalies that I failed to observe initially.
First I tried to put my ST sim card out my AT&T SGS, and get no service. No big shock initially since I have to change the APN info. Couldn't do that cause option is dimmed.Checked further, No IMEI, IMEI SV, or baseband. Took sim out and observed that I get NO sim error at startup, just "no service". Tried an AT&T sim from a friends Vivid, same result.
I was hoping that the sim card reader just might be bad, a cheap easy fix and apparently some what of a common issue. Haven't ordered one yet until I get more info on whether the no sim error and no IMEI etc are related and it's not a more serious hardware issue. I don't have a problem with repairing hardware if needed.I'm a noob here, but have a brain like a sponge, so any thoughts on how to proceed with diagnostics would be appreciated. Thanks in advance
No imei is really bad...
No one here can help you recover it without a proper backup... I have no idea how to back it up nor restore...
If you don't figure it out I'd have to suggest flashing to stock... prolly via ruu and go to an at&t store...

I don't think (but don't know 4 sure) that this phone is anything other than an out of the box stock configuration. I don't have service with AT&T so I don't know how much help they would be. I did check with them to make sure IMEI printed on the phone wasn't blacklisted and it's OK. All I have done was to do a factory reset to clear all the PO's stuff.
Does anybody have any more ideas? I am wondering if I don't need to replace the motherboard and or just the simcard/sd part. Changing the motherboard would mean a different IMEI right?
No imei means something went wrong with the bootloader. It's unlocked? Did you try to S-OFF?
I believe flashing a rom stock via RUU (that's it, flashing the PD.zip file) maybe can fix the problem.
At worst you must change the motherboard and yes, you will have a diferent imei.
I may be wrong, but I see no sign that anybody has done anything to change ROM or anything else on this phone. I'll try to do a S-off, and unlock it since I want to use it on ST anyway.
hello,
i've also same problem here
flashed with stock rom but no luck ,
bootloader locked and s-off
searched forum but no success story
i think i'll return it
Well I finally got a new SIM/SD card reader and installed it. No change.Tried ST, AT&T, and T-mobile sims
Still get no SIM error when booting with or without a SIM card, has an X on signal strength, and it doesn't even say "no service".
Same as to IMEI etc. info, nothing shows up.
Am I going to have to change mainboard? Or is it possible firmware/ROM changes could fix it?

Unlocked the bootloader tonight, no problem. Will try s-off tomorrow.
Where can I get a stock rom file?
I'll only ask this dumb ? once: Is the OS (JB,GB,ICS) different than the rom? I'm still running gingerbread 2.3.4, should I got to ICS or? Will that have any affect on the imei issue?
I might just be getting some experience with this phone if I have to do it all over with another mainboard.
OK, so I decided to play with this phone again after my SGS1 was freaking out yesterday. I finally found and used a phone dialer code do download the ICS update, and it downloaded (via wi-fi), installed and rebooted fine. In fact It apparently fixed my IMEI and SIM card problems because when it booted the first time with ICS it showed a big icon "no SIM installed" ya hoo!! checked IMEI in settings, all was good. Played around with settings/menus a bit to familiarize myself with the differences, then restarted...NO IMEI again, and no sim error without any SIM installed On the next 5-6 restarts it worked fine all but once, (total on time of around an hour) but now every restart (10+) it's back to same original issue: no IMEI shown and no SIM error. I still have no AT&T compatible SIM card to really test it but if it doesn't give me a SIM card error (no SIM card installed) it's a moot point.
It really puzzles me that it appeared to work at all if I have a bad mainboard. My daughter in-law has a Vivid with a bad screen she's going to give me to use for parts (mainboard) but I'm not sure if there's not still some hope of salvaging the current one.
Comment, thoughts etc... Please
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
System details: imgur dot com/zwiD3pR <--(sorry new acc)
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

So I flashed Dr. Ketan's ROM and saw that the model number displayed was wrong, simple aesthetics I know, I decided to edit the build.prop settings to fix this, when I restarted my phone, it suddenly displayed that I had network sim locked. What I found out next is that if I only place my main sim, there would be no problem, but if I add a second sim to sim slot 2, the network sim locked appears. I even re-flashed a stock rom, still the same issue. Can anyone help? thank you
EDIT: to clarify, both sim slots were working just fine before I flashed Dr. Ketan's ROM and edited the build prop setting to fix model number.

this is strange issue and i believe a rom can not do this. Did you try flashing any other kernel? is your sim password locked?

Those were my thoughts. None of my sim cards are password locked. Tried them on a different phone which was definitely unlocked. Both sims are working fine. Brought it to my carrier (I'm not from the US) and explained to them my problem. I also mentioned how weird my situation was in the sense that both my sim gets network locked if both sims occupy sim 1 and 2 slots but if I use my carrier's sim( the carrier with whom I have a plan with) then the sim would function normally, otherwise network sim locked.
My carrier declared it defective and is now shipping a new one. I guess that somehow solves my problem. It just irks me though that my experience seems to be so unique that I couldn't find any solution online and no one with whom I've talked to seems to know how to remedy the problem.
edit: I did not flash any kernel, I had stock kernel the entire time.
Hi. I am a complete noob when it comes to rooting Android.

THIS ISSUE HAS BEEN SOLVED. PLEASE SCROLL TO POST #89 ON PAGE 9 TO SEE THE SOLUTION.

***************************************************************************************************
I bought an *unlocked* Samsung Note 9 N960F/DS (Exynos 9810) international phone from a seller on ebay brand new and sealed. Received the phone yesterday (10/19/2018) and popped my working existing sim card from my iphone 6 with T-mobile into the new phone and it *worked*.........except no wifi calling.
Since my house has terrible reception I really do need wifi calling in order to receive calls (I use Skype for outbound). I decided to root and install Detonator (tekhd) even though I've never done this before. Somewhere along the line I messed up and installed the latest LUX ROM because I misred Tekhd's guide on Detonator (my fault).
Here's where I stand now: I found a stock ROM for this model (N960F/DS) and reinstalled it using Odin3 v3.13.1.
After a successful flash when I insert my working T-mobile sim I get "SIM network PIN blocked. Enter SIM network PUK."
Here the Service Provider SW shows XEU/XEU,XEU/MYM
I get the *same* message when I insert a spare T-mobile sim I happened to have that was confirmed as available with T-mobile customer service. If I take the working sim out and put it back into the other phone it works without a problem. I think that rules out the sim cards having issues.
Earlier when I had the phone rooted and Detonator installed (and working), I got a different message when I inserted the SIM:
Network Lock: This device can be remotely unlocked if eligible.
Please use the "Device Unlock" application to unlock the device.
Make sure the device has an internet connectivity to use the "Device Unlock application".
Here the Service Provider SW showed TMB/TMB/MYM.
I tried looking for a T-mobile Unlock App apk to download but could not find a recent one. I would get a "Device not supported" error. It seems T-mobile has taken it off the Playstore.
Now, I can't install a stock USA ROM from T-mobile because those ROMS are only for the Snapdragon versions and I have the Exynos chip. I was given two unlock codes over the phone with T-mobile customer service to try and unlock the Pin lock but they both did not work.
Do you think an unlock service will be able to provide me with a valid "Sim Network PUK" code? I'm happy to pay for the service if I can just get the damn phone working. I've spent almost $770 on this phone and in hindsight should just have gotten the T-mobile branded phone for $100 more. I'm really at a loss as to what I can do to rectify this situation.
Also in hindsight I should have done more research before purchasing the phone and also should have backed up my partition in TWRP........You live and you learn.
The irony here is that I had an unlocked phone.....and now it has somehow gotten locked.........by the carrier whose SIM card is working perfectly fine......in a different phone. The device was paid in full btw.
Any help is greatly appreciated. Thank you in advance.

this is a first. I always though once the region lock was lifted it couldn't be relocked( to me it seems to be a region lock issue, which if it is you need to make a 5 min call on region soil... good luck)
anyways check on your box there is a sticker with model and serial . find what carrier or region its from and grab that firmware and flash it. might want to factory wipe everything (including cache) in the recovery before booting it up indownlaod mode to do Odin flash.
also remove sim before wiping/ flashing, let it boot and do the initial setup then insert sim.

I did wipe and reinstall the stock rom with the sim removed. The strange thing is..........I get the same message if I insert an old, blank, unused t-mobile sim into the device. Plus the working sim works fine in my old phone. So how could it be that the sim is locked?
There is nothing on the box that says anything about a carrier. This was advertised and sold as a factory unlocked phone which by all indications it does seem to be. The only thing on the box that says anything about country is that it was manufactured in vietnam.

Yes there are stickers. But it is not associated with a carrier, specific region, or country. I just see IMEI info on the sticker on the back of the phone and S/N.

did you flash one of these?
these should be the original firmware U1 and the lates U2 which if you flash wint be able to downgrade bootloader but shouldn't be causing rhe sim lock issue.
flash U1 first and see if it fixes your issue. then try the October U2 just for fun
you can also download it using samfirm tool
enter 960F and MYM in settings it should also be a faster download then the web links

ok so it's too late for U1 . ure phone is already on U2 latest bootloader. so flash the October build
but be sure to wipe all with no sim before flashing
and in Odin fill in all slots and for csc use CSC but not HOME csc file.
good luck

yeah might as well use tarp. and erase all. but before, did you sift through internal s or ext s for an efs backup that detonator might have made automatically?
check for a folder called .backup and or for a file like:
efs_backup.img.gz
efs_backup.img
or anything similar

No, but I did download Dr. Ketan's tool to make an efs backup. But that was way later in the process....so it wasn't the original efs directory......It was after I flashed my current "stock" rom. I'm going to try and find another site to download since that one will take 2 days on slow speed......
Btw what does the ZBD mean? MYM I figured is Myanmar......

Hey guys, while I am not new to this, it has been several years.
I recently got a used unlocked Comcast/Xifinity S21 (snapdragon). I have a T-mobile SIM card.
I tried flashing the rom to stock U1 which worked great but my signal is poor. While connected to Wi-Fi, the mobile networks/Network Operators in settings shows "T-mobile Wi-Fi Calling". But while I am not connected to Wi-Fi, the Network Operators shows Xfinity Mobile.
Under software information, it shows: CCT/CCT/CCT
How I can fix this? I made sure to not click the HOME_CSC when using ODIN, and I even did this twice. Should I just try the U firmware instead? Or was this because I left the USERDATA section blank in ODIN? (I used XAA, and then TMB a second time under Frija to download the files though).
Thank you for your help
I believe you are doing something wrong. Make sure you remove the sim card from your device and flash XAA software go through the initial setup process after the device reboots. Only after the device is fully loaded and the setup process is complete insert Tmobile sim card. At this point your device should show XAA/XAA/CCT. You cannot change the last value at this time, this value indicates the original carrier this device is purchased from. I believe Samsung needs to release a patch that will let you automatically change the last value based on the sim installed. At any point you want to revert this value to CCT/CCT/CCT just install a Comcast sim card and wait for Pop up that says Sim information updated and then reboot your device.

Yup, i linked back to the post that helped me in the last post (it just has the same title as this one). Similar thread i created in the base S21 group
