I have owned the Samsung A32 5G for about a year, SM-A326B/DS model.
For about a month, with my sim cards and with any SIM card I have tried, even of various telephone operators, the phone recognizes the signal only for a few moments, about a couple of seconds (and in those 2 seconds any SMS also arrive ), then the word "registration to the network" appears and since that moment the signal bars go to zero, as if the SIM was not present, or as if the SIM has expired (I can only make emergency calls), and therefore the phone is "without signal", therefore no SMS coming etc.
I tried various SIMs and various telephone operators, the same problem, with both SIM slots.
The phone has the latest official update:
One UI 5.0
Android 13
Build TP1A.220624.014.A326BXXU4CVK5
The phone has not undergone impacts or water, it is perfectly intact, it seems "new".
What could be the reason for this malfunction?
Is there anything that would be possible to try to solve the problem?
Thanks in advance for the suggestions

I have gotten this message 3 times in the last 5 days. Each time I need to do a reboot to restore cellular/sms service (toggling airplane, wifi, bluetooth, sync, and 4g do not restore cellular/sms). The phone has the same AT&T sim card since day 1 and I have never removed it.
Is this a faulty phone, sim card or both?

Did the sim come with the phone? ATRIX 2 needs newest of sim cards to function properly. If that's not the problem then I'm not to sure.

Yes, same sim card that came with phone.
Could be a faulty Sim, i've had that happen before with other phones, just go to at &t and show them the problem, they should replace it for you!

I wasn't able to solve this problem about an year. But did. And totally sure that it is Device's defect (in some cases it is a ROM deffect as in my case, in other - hardware. Smth like stack overflow issues at GSM controller or so). A year ago when I had face this "sim card does not allow connection... " problem, there are no google serch results on this keywords request. Any. To remove this message I was ought to reboot my device every time it appears. And I was thinking that it is normal behaviour for my device. But now there are lot of complainings at the web ( minimum 5 of Galaxy Tabs P1000, thousands of HTC Disire, few motorolla Deffy, 10 Galaxy Ace, few of Nexus S and so on), so I understand that I'm not alone, and problem is known. So I went to Samsungs Service and they confirmed that it is famous problem, have flashed my phone with some magic ROM (magic because it is official but does not available anywhere in the web, XDA or samsung sites! ) and now my phone works fine. Any other solutions like battery removing, *#*#4636#*#* sirvice menu, new sim-card, flashing variety of modems and roms, didn't helps me. This is not faulty sim. This is serious device's defect. Bring your phone to manufacturer and let them repair it or give your money back. This is their problem not your.
using old 3g prior sim card
With ATT---If you took your old 3g sim card out of old phone and used it. You will get this message. You need to activate the 4g card that came with phone

I have exactly the same issue randomly at times when I try to register on network manually (MTNL Dolphin 3G - Mumbai). Unrooted MB865 ver 2.3.6 & updated on 18th May 2012 to System Ver 55.28.37.MB865.AsiaRetail.en03. If I keep the setting as Automatic in Type of Network & Operator it functions fine fluctuating between Dolphin for local access & CellOne on roaming access in the same area based on cell tower connection the phone registers on alternating between "E" & "H" automatically based on cell mast direction proximity, however if I select 3G only and uncheck automatic for operator then the phone searches for signal for a very long time and fails to show any operator saying "no connection available" & sometimes when "Dolphin" network does appear and try to select manually get the error as "this sim card does not allow connection to this network". I did complain with the service provider and they were supposed to get back to me after checking in their switchboard exchange where I also provided them my SIM number in addition to my cellphone number(no response). Also as is case with poor service of all Indian cell network providers even in urban cities, also face random peculiar issue of call not being received inspite of signal available on the phone & network asking me to recheck the number I have dialled while placing outgoing calls though it is ok and signal is sufficient. Also "Network Speed Booster" app looks like a lot of bull (any other good apps??)
I needed to know using the secret Menu *#*#4636#*#* for 3G GSM service which kind of network I should ideally select for best results & does this setting override the regular menu network settings??
I get "G", "E", "H" randomly based on my locations but no "3G" or "H+" and further at times these icons are grey and sometimes blue and in either cases randomly at different locations sometimes data throughput is not there as only one of the arrow shows active blinking. Any advise on the status based on colors and the blinking of the arrows?? Thanks!
Tl;dr: OPO refuses to connect to my default home network, instead chooses roaming. Cannot text or call and data will not work on roaming (they used to).
BACKSTORY
Hello, my OPO was working almost perfectly for 2 years without any significant damage like water or drops. Then, in November of 2016, I went on a trip to Europe for a few months (I live in Canada), and used my OPO occasionally there, by roaming when I needed to make calls. (Used my regular cell plan with an extra worldwide option)
When I got back to Canada, I had a stopover flight in Toronto, where I was able to connect to my HOME network and make a call and some texts. Also used some data during this time. Then, I flew the rest of the way to Vancouver. There, I was able to connect to my HOME network and send some texts and use data for about an hour. That was at the end of February.
THE PROBLEM
Since then (last 1.5 months) I have been unable to connect to my HOME network. My OPO will only connect to the AWAY/ROAMING network, even when I go into Network Operators and manually force HOME - it just says it's unable to connect at this time.
When connected to AWAY, I typically can not do anything. However, sometimes, I will be able to receive calls, and send and receive texts. No data, and no sending calls. Before this whole problem started, I was usually able to call and text and use data on AWAY.
WHAT I HAVE TRIED
Choosing different Network Operators, different Network Types (WIND is WCDMA). Problem persists.
Deleting and creating new APNs from the current information on carrier's site. Problem persists.
Ensure that my OPO can read the IMEI. It does
Went to carrier (WIND, aka Freedom Mobile) and tried the store's demo SIM that uses an alternate account. Problem persists.
Carrier tried my SIM in their own phone. Worked on that phone.
Carrier gave me a new SIM for my account.Problem persists.
Reset my OPO to factory defaults, including apps and data. Problem persists.
Format my OPO and flashed different ROMs (including various CM and stock releases from KitKat to Nougat). Problem persists.
Flashed different modems available for OPO from the various original CM11 ROMS, as well as one from a CM12 ROM. Problem persists.
Tried the SIM card from a friend's phone on a different carrier (Virgin Mobile in Canada).Problem persists.
Removed my StyleSwap cover and ensured antennas and antenna pins were clean and making contact. Problem persists.
Tested Wi-Fi, Bluetooth, NFC, and GPS to ensure other antennas were working. They are functioning
Use online tool to see if IMEI is blacklisted. It is not, and problem persists.
Took my OPO with me when travelling to various parts of British Columbia over 100KM away to test different cell masts. Problem persists.
CONCLUSION
That is as much detail as I can think of. I would be happy to provide more if it may help. I already had a chat with OnePlus's live support and email, and was told I would need a repair, which would cost a few hundred dollars.
I am also thinking about buying a used/broken OPO for cheap and swap the motherboard, however there are not many available near me right now, and this also carries some risks akin to buying stolen phones.
I am pretty tech savvy, so feel free to go into as much detail as you can.
Thank you for any and all the help you are able to give!
Hi
I'm having a strange problem with my new A51, with two SIM cards in it.
After an indeterminate time the phone disconnects from cellular network.
It still shows on to the both cards the signal strength, but the phone no longer receives calls or has internet access throw cellular network.
And if I call any of the SIM card numbers from another phone, I get a network message saying the phone is disconnected.
All other functions on the phone seams to be ok. Turning wifi on and off has no effect in reconnecting to the cellular network.
But... If I try to call from A51 to any other number, the phone reregisters on cell network, the call is done and from that point on, all goes to normal. I can receive calls again and access the internet using the cellular network...
I went to the store were I bought it, and the gave me another one, but with the exact same problem.
So I believe is not a hardware problem.
I believe now that It could be a SIM problem, on one or both SIMS, which is odd
A software problem on A51 the need's to be patched, which is odd because it has effect on the most basic feature of the phone, which is receiving calls...
A strange behavior of the phone with my cellular service provider, which is odd too...
I'm trying now with only one SIM to see if the problems happens too...
Can any one suggest any other test or debug to try to clarify this issue ?
Thanks

My wife have exact same issue with single sim.
Hey guys, really hoping someone is able to help me.
Back in September 2020 I purchased the SM-N9860 variant from T-Dimension for use in the UK on EE's network. Everything has been running smoothly since day one, up until yesterday (31st May) where the phone would constantly struggle for signal, flip flopping between "No service" or extremely slow 4g. If I try to make a call I get the "Not registered on Network" error message.
Since then I have done everything I can think of:
- Restarted the phone several times
- Switched Airplane mode on/off
- Manually selected my carrier
- Reset network settings
- Tried my sim in another phone (which worked fine), and tried a different sim in my Note 20 (exhibited the same behaviour of "No service")
- Checked IMEI but it's not been blacklisted
- Tried my sim in the SIM2 slot
- Full factory reset
but none of them made a difference.
Tonight I decided to try and flash different firmware to see if that might have any effect; both TGY and BRI firmwares were flashed successfully with Odin but neither have solved the problem. I'm now at the point where in my home I can see the 4g symbol appear above the network status for 30s - 1min but it never actually loads any data, before returning to "No service". Compared to my fiancee's S10+ which is also on the EE network and easily hits 20Mbps without worry in the exact same room.
Does anyone have any suggestions of what to try next? Has anyone else encountered this?
Thanks,
RBrNx
I've spent some more time investigating this and I am 99% sure it's an issue with the device.
Below you can see a screen recording of the issue that I made this morning while I was out a walk, you can see it goes from having signal but no internet ("Emergency calls only"), to "No service", then to 4g but I wasn't able to even load a website, before it moved back to "No service".
I've also attached two screenshots from the NetMonster app, one is from my Note 20 and the other is from my fiancee's S10+. Both were side by side when the screenshots were taken - mine has no service and her's has 4g.
I've since tried a number of other SIM cards in my phone, including another EE SIM and a Three SIM - both work immediately in the S10+, but neither are able to register when put into the Note 20.
I tried to contact Samsung Support but they were next to useless. The UK support team told me I'd need to contact Hong Kong support "as they have full access and information", but all the HK support could do was tell me to visit the HK Support Center...
I'd love to be able to fix this issue but I'm not sure what else to try
EDIT:
Some more information that I forgot to add - When I am out of the house I can occasionally receive calls/texts or use the internet, so I know for sure that they are all working (i.e EE haven't blocked my account) but most of the time I am stuck with "Not registered on network"
I'm wondering if it's an issue with the antennas, it's almost as if they are somehow weaker or less receptive than they were a few days ago
Does it behave this way when in safe mode ? How about in 3G mode? If it's hardware then Samsung doesn't recognize devices that are from other regions in relation to warranty work. You'll have to test the after sales support of T Dimensions now. Failing that sell it as is on eBay for parts or try and trade it for another device.
I'm using the same device on Vodafone UK and no issues here at all
I'm using an N9860 HK model, also from T-dimension, with EE since last autumn. I have not had any such problems with mine.
I haven't flashed or rooted the phone, but I have tinkered in the service menus in order to gain 5G service and possibly other service improvements.
Yeah, same for me. Changed the 5g whitelist settings but no root.
I noticed a few days ago that my phone (SM-S908E) had no service from my network provider (appears as "emergency calls only" or "no service").
The SIM and all its services works perfectly fine on any other device, and any SIM (from the same provider) gives me the same issue on the S22U, the network appears when try to manually select it, but never connects, it takes a lot of time and just a "Not Available" appears later.
I noticed later, while moving, I have perfectly fine signal sometimes, even 5G when available, I noticed this outside and near cellular towers.
My network provider says everything is fine on their side, the SIM and the device itself (well they only checked the SIM port). It make sense to me because I can get the service in my old S9 and S20 with that SIM.
My conclusion is that the device is not able to get the signal as before (like a range thing?), and because I don't know when it started but I know I updated an OTA on early feb (I noticed this issue on feb 5th), I want to ask you guys:
- Is there a chance the update was wrongly downloaded/installed and is affecting the mobile network?
- Can I redownload the update on any official way to reinstall it? I remember exactly that as a "repair" function on smart switch pc but is not availble on my device.
- Can I downgrade to my previous firmmware (with odin) to see if this was a update error, and if I can, that keeps the official status?
I have warranty yet, but I don't want to go to service center unless neccesary, and if I can try something and keep that official status before losing my device for a few days, that'd be nice
