Lost 3G/4G on SIM2 after flashng. - K3 Note Q&A, Help & Troubleshooting

After flashing my K50 T3s, first with Cyanogenmod 13 (unofficial). there were no SIMs found and no IMEI.
Then I flashed with S433_StockRom_BySmiLeToLiFe_TurkDevs
This recovered the SIMs along with the orignial IMEI.
But now SIM2 only works on 2G. SIM1 works fine on 4G.
Any ideas?

I found the answer. You have to activate data for Sim 2. Then it works on 4G.
But I didn't have this problem on the earlier system on this phone.

SIM problems

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.

XT1079 only 2g or loose sim card

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.

3g and LTE not working

Hello! My 3g and LTE stopped working. The ROM i was using was CM12 LBL. I downgraded to CM11 LBL and still have this problem. I don't have signal and mobile data.
After testing the sim card on other phone i found out that the problem is in the phone. It's not mobile operator problem.
Any suggestions on what to do ?

LineageOS 17.1 N950F/N No Cellular Network "Emergency Calls Only"

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?
