Sim 1 stopped working note 20 ultra d/s - Samsung Galaxy Note 20 Ultra Questions & Answers

Hi guy. On my note 20 ultra, sim1 stopped working. I thought was network issues but it wasn't. When I put on sim slot 2 it works, when I change sims around sim 1 won't register to a network. If I activate wifi calling, I can make calls from that sim. I have even check status of my imei, and is not blacklisted. (I have wiped cache partition, I have reset network settings, I have rebooted, I have deactivated Sim tray and reactivated again) have anyone experienced this issue?

something for Samsung technical support to look into

[Completed] SIM card detected but no signal

Hi, I recently got an Infinix HOT 3 LTE. It's a really great phone, but I have a problem with it, my 3G SIM card isn't working properly.
When I insert it and start the phone, the card is detected, I enter my PIN code, then when I try to make a phone call it says "Cellular network not available". I tried switching the SIM card slots, both didn't work for my card. Then I tried to change the network provider manually and all and I also tried changing other cellular network options over and over again but nothing worked, I also tried switching airplane mode on and off. I got frustrated with this problem and I decided to factory reset my phone, but the problem was still there. After that I tried using someone else's 4G SIM card, and it worked, so there's no problem with my phone or SIM slots. My 3G SIM card is fine I think, it works on my old phone, as well as others.
Please help if you can.

Greetings and welcome to assist. Are you sure the phone is compatible with your carriers bands? If you are sure try asking your network provider for a new sim
Good Luck

Incoming call not reachable in slot one when slot two sim net is on

Hi, i am using Le 1s. Using Idea sim in slot one and jio in slot two. when jio sim mobile data is on, incoming call to slot one, idea is not reachable ie. busy/not reachable/switched off tone is coming to the dialer. i even changed the sims to vise versa, but the same is happening........Anybody having solution for that?
Could you please elaborate the issue...
i.e. you get busy tone for which slot.
like if Data is on for Sim 1 then sim 2 is busy/unreachable. That is you telling.
Cause in Leeco 1s Jio will not work in Sim 2 Slot. Cause its GSM not VOLTE.
Solution: Go to phones default dial pad and press #*#*3646633#*#* i.e. *#*#engmode#*#* in that Telephony>Mobile data service preferred and uncheck the box. Now restart the phone and check.
Do let me know if you need more help.

Dual sim settings problem

Hi. I`ve got an MHA-L29 and I`ve got a problem with dual sim settings. In dual sim setting menu if I select default mobile data (4G services associated with default SIM) on SIM 1 then I lose the signal from that sim (Emergency calls only) and I`ve got SIM 2 signal. If I select default mobile data on SIM 2 I lose signal from that sim and I receive signal on SIM1. Basically, I can`t have both sim working (network signal) because I need to set 1 SIM on default mobile data and the one that I set it`s losing signal.
Maybe someone can help me. Thanks

This is strange behavior.
By default there is no problem. See my screenshot.
I suppose it is mobile operator's problem.
What is your full version (settings / about phone / build version) ?
What is your country and mobile carriers?
It`s not a mobile operator problem. I use the same sims on mate 8 and it`s fine. It`s exactly like in your screenshot, sim 1 default mobile data and I lose signal, and I have signal on sim 2. If I select sim 2 default mobile data I lose signal on sim 2 and receive signal on sim 1. So basically I can`t use dual sim and mobile data.
I`m in UK with BT and Lycamobile.
Build version was MHA-L29C432B198 but I`ve tried different things and now I`ve got nrd90m test-keys.

Agree, C432 region is for UK too. So your bug must not exist, but it is here.
Nrd90m test-keys means that metadata from oeminfo does not match with current ROM.
Did you try to rebrand? If yes, just flash ROM again what you flashed last time.
I`m trying now to rebrand, watching tutorial but I`m stuck at
After device enter TWRP, connect to USB cable.
Press ENTER key to continue...

Something blocked adb. Maybe HiSuite. Turn it off, then check that pc recognises device.
adb devices
You can issue to refresh adb
adb kill-server
Phone must be in twrp.
I`ve managed to do all the steps, but after restart I can`t get past the Huawei logo, phone enters in Huawei eRecovery where I have Download latest version and recovery (restore your system with wifi) reboot or shutdown. I`ve tried to restore the system with wifi but I can`t (getting package info failed). I don`t know what went wrong during the process but the phone it`s stuck at huawei erecovery.
So now I`ve managed somehow to update emui to 8.0 and android 8.0 and I have build number MHA-L29 8.0.0.321 (C432log), but the initial problem it`s still there.
I still can`t use mobile data or both sims in the same time. The sim selected to be default mobile data lose signal.
I`ve tried to use 1 sim and sdcard but I don`t have signal because the sim it`s set by default to be mobile data.
Anyone?

Seems to be hardware issue. Do you have warranty?
I don`t have warranty. Both sims slots work fine one at the time, not together.
I need 10 posts on the forum so I can upload a screenshot.

OK. Last thing - try to delete and recreate apn settings.
Don't think that they all incorrect, but maybe one of them...
The Mate9 is active/passive: it's impossible to make a call using sim 1 and using mobile data with sim2 but in stand by you can receive calls on both sim. This limitation is not present on mate8 and mate10.

I`ve tried other sims, put new apn and it`s the same.
pgmunzi I can`t because I don`t have signal on one of the sims. In dual sim settings, I need to set sim1 or sim2 to be default mobile data. With sim1 set on default mobile data, I`ve got signal on sim2 and no signal o sim1 (emergency call only), not even to receive. With sim2 set on default mobile data, I`ve got signal on sim1 and no signal on sim 2.

You can only have data on SIM1. Both sims can be used for calls and SMS (to my understanding). If you have two SIM cards from the same network it should not be a problem, overall. If you have two different networks (one on each SIM) then you might have some issues.
If you have the SIMS on the same network, and they use the same APN, you might want to copy the settings to two different APN's a label them for SIM1 and SIM2.
Also be careful of what version of OS you use. If you download a version that is originally branded for something else, then expect problems. There are also "Gotcha's" with firmware that is taken from one device and reconfigured to work on your device. Usually this is a matter of rebranding and copying underlying code over. This too causes issues with dual SIM phones. I have found this to be true with my MHA-L29C567. Sadly, I would love to have a memory card under the second sim slot along with a second SIM, but I have yet to figure that one out...

Just got the same problem (2 sim cards from same network, only obe working at a time) and thanks to you it's solved. I just had to rename the second APN differently.

Dual SIM VoLTE Verizon and Fi

Hi all,
Here is my situation and problem. I have 2 Sims:
SIM 1: Google Fi - my personal number, I want to use it for phone calls only even though it has a small data lan
SIM 2: Verizon - work sim, I want all the data to go through here.
My setting is phone call sim 1 and data Sim 2.
When I make a phone call via SIM1, I lost LTE on my SIM2.
I did call Verizon to get the CDMA LESS feature turned on.
If I were to change the setting to phone call and data through the same sim, then VoLTE works just fine. So I think this is an issue with the phone itself/settings.
Thoughts?

You need to go into settings "SIM & network settings".
Select "Dual 4G networks".
I don't have your issue.

I have a similar problem. Voice on SIM1 data on SIM2 different carriers. Receive calls and text OK answering won't work. Roaming in Europe. Worked OK prior to recent update. Same setup works on Samsung S10e

Can't believe there are so few of us having this issue. Why would the LTE turn off when I'm not even using that sim?
Probably many are using just a single SIM.
Have you tried switching the sims in the slots?

I have no help. In January Mint had an issue where their SIM had to be in slot 1. So I flipped SIMs. Truphone won't work either.

Dual-SIM problem

Hi guys!
Did someone of you noticed some problems with using two sim-cards? When i install the second sim card i am constantly getting problems with loosing cellular network connection. There is something strange going on...I tested the new sim card on the other phone and its working normally (so its not the problem with the sim card). Is there maybe a solution to this problem?
Thanks!
Hi guys! As a last resort i did a factory reset of the phone. Its all working now as it should! Strange. Must have been some software bug.
I have been using dual Sims since Nov 2019. I don't have any problems with it so far.
Dual SIM not reachable
Yes, I have constant problems, and I think it's since April or May update.
I use two sims, and sim A constantly keeps "telling" the caller, that "The user is in another call and can't be reached". Then I get an sms with "missed call".
Outgoing calls take lots of seconds to connect.
I've tried shifting the two sims, problem with the same (!) sim card. You'd think this is a sim A problem.... I got a new sim from the "A" operator. Same problem.
Using just one sim in the phone, everything works well, regardless of which, even sim A works fine.
In any phone, sim A works fine by itself. There's something with the software or some setting in the Xiaomi that messes this up.
Support at operator blames the phone.
Support at Xiaomi blames the sim.
