I've tried everything, so hopefully someone can shine some light into this issue.
I bought a new (unused but from a 3rd party) Samsung Galaxy A50 (A505U) Verizon branded and unlocked. Got a sim card from Visible and went to get it connected. Nothing. WiFi works, everything works, but no cell service.
Here's what I've done (some multiple times)
- reset everything to include network settings, hard reset, etc
- removing the sim, resetting, putting the sim back in. I always get a notification saying the sim card is removed and it goes away when I put the sim back in, so it is recognizing a sim card is in there
- switched sims with another Visible phone/sim and nothing. Both sims worked on other phone but neither worked on this phone
- tried getting into the hidden menus but none of them worked
- talked to Visible tech support which upgraded the issue to the highest level and concluded it's the phone
- Visible believes it's the APN settings but I cannot edit current APNs nor add new ones (grayed out)
- manually add networks, I can see Visible, TMobile, ATT, and some weird numbers, but when I try to connect to Visible it says cannot register on the network, other networks say the sim is not setup for them
- sometimes I get the icon that shows all bars but they're grayed out, sometimes it shows 3-4 bars lit up, sometimes even shows a 4G icon, but mostly the grayed out bars
- sent the phone to Samsung, they tested it and found no faults, guess the hardware is good, ruled that out.
- got into dev options but I'm aware the OEM unlock is not on option on the A505U, not sure if I can change anything else.
I'm out of options. Any other ideas? I think if I can either get into the hidden menus I'll be able to diagnose it better, or if I can somehow change the APN settings I'll be able to set it up. Visible tech support thinks it's the APN, which makes sense to me, but I can't change them.
Any help is greatly appreciated.
I was able to get into the CSC change function, there's not many there, but would changing the CSC help? If so, which should I go to?
I've had a similar issue. Was working fine until the Android 10 update arrived. Since then, it won't work with my total wireless sim card. Tried 3 different sim cards on it, but nothing. Can't add it do anything with the APN, and getting into the phone info hidden menu doesn't help any. I suspect it's a bug in the new firmware or something like that. Works fine with a Verizon SIM though.
Update: Verizon SIM no longer connects to phone. Still works with LTE data. It seems that the CDMA radio quit working with the update to Android 10. Must have been collecting to the Verizon network with VoLTE until it updated the provisioning or something.
So, I finally figured out a workaround for mine that was able to get both data and voice networks to connect while using total wireless, which is an MVNO on the Verizon network. I pretty much narrowed it down to being an issue with the modem not working with CDMA. What I did was download the last Android 9 firmware and flashed just the modem (file starts with CP_) using Odin. After that, I rebooted it and voila! It connected.
Just thought i would give my experience as i just delt with this. i got my 10 update this morning nd let it update and apon a reboot i lost all mobile connection, a signal bar would show for a few seconds looking like it was trying to lock in a signal and it would go back to the ⌀ symbol. i tried flashing the android 9 modem from 2 different updates and neither fixed it. i just decided to order a new phone as i feel its time anyways. my next attempt will be to flash android 9 back using odin then just throw this phone up on craigslist
edit: odin successfully flashed back to android 9 and signal now works again. so if anyone has this issue you can try the method above of just flashing the modem and if that doesnt work you can go back to 9 and restore functionality of verizon mvno's

samsung a50 not connecting to VZW towers (red pocket)
My phone is doing the exact same thing and while I can appreciate how you resolved the issue it doesn't make much sense to me.
I use Red Pocket for my network. (Which uses Verizon towers - I use the CDMA Sim)
Before this major update to 10 my phone worked flawlessly. Now it won't connect to the network much like you guys have stated in this thread. Mine will connect intermittently for like 3 or 4 min tops and then get kicked off the tower and will actually not show any bars (Circle with a line through it) to show no service for about 10 or so minutes then restart the whole process.
I also have a work phone (2nd phone) that is directly tied to the verizon towers on the verizon network. If I take the sim out of that phone and put it in my samsung a50 the samsung a50 is happy and can make phone calls, send texts, and stays on the vzw towers with no disconnects.
If I take my red pocket sim card and place it in my work phone that phone also works just fine - send messages, make phone calls, and stays on the vzw towers with no disconnects. (work phone = iphoneXR - it's free, sue me)
Even though reverting the modem obviously fixes your issue I do not think that is the actual problem. It also doesn't seem that a third party carrier is being randomly booted off the towers, it seems to be a glitch with third party carriers using third party sims utilizing this new android 10 software that VZW towers do not like.
Which obviously points to an issue with Samsung's latest software not being compatible with third party carriers.
I can't seem to contact Samsung in a direct manner to resolve this issue as they want me to take it to a third party store to have it looked at. I spent 2 and half hours with tech support from red pocket and they came to the conclusion that VZW was doing "upgrades/maintenance" to their towers in my area. (whatever that means.
Any ideas on how I can contact Samsung directly to detail this issue to them? I really do not want to have to root my phone in order to use odin to set my modem back to version 9 as I'm hearing that doing so voids all kinds of implied warranties with the phone and it's only 6 months old.
Appreciate any help that you guys might be able to steer me towards.
Thanks.
Before this major update to 10 my phone worked flawlessly- They Told you the answer, Odin # 9 or if its under warranty take it back Good luck.
My phone (SM-A505U) wasn't even working on visible before android 10.
See my post at the end of this thread: https://forum.xda-developers.com/ga...official-firmware-t3955727/page2#post83845605
I have that problem too. Where I can download v9. I got the Odin.

Hi Guys.
So received the phone on Thursday, Friday I did a sim swap from my normal sized sim to a micro sim. I waited the whole day but the phone didn't have any network access.
Today when I woke up I I switched the phone on hoping that everything will be fine, thinking the simswap just hasn't gone through yet, still no network access. I took out the swim from the phone and switched with my ipad, the sim was working in the ipad, and the ipads sim also didnt give the phone network access.
In the top right corner it shows full bars in grey, cant make emergency calls or anyhting.
In the about section of the phone, I have ALL the details present, baseband version is there, kernel version is there.
In Status section, network is unkown, signal strenght is -83 dbm 15 asu, network type unkown, service state is out of service, and the rest is also present.
I thought the phone didn't properly register to a network, so went into settings - wireless networks - more settings - mobile networks, but it gives me a insert sim card message.
The phone is reading the simcard fine because it asked for the PIN when switching on.
When trying to make a call I get, it says "Not registered on network"..
So what am I to do? Vodacom can only pickup the phone and exchange it on Tuesday, so was hoping that this might just be a software issue that can be resolved by a flash.
I have tried resetting / hard resetting the phone numerous times.
Its the Note 2 N7105 LTE Version
Any help would be highly appreciated.

Great thanks.
I tried this but didn't solve the problem. I am using the same sim that I received from the carrier with the phone they shipped.
I have played around in the menu however, maunally setting the band and so forth, just restarted and started receiving sms, so basically if not for your post I would not have solved this.
Thanks
I have isolated the problem.
In the service menu - UMTS - DEBUG SCREEN - PHONE CONTROL - NETWORK CONTROL - SERVICE DOMAIN
There are 3 options
1 CS + PS
2 CS ONLY
3 PS ONLY
CS seems to be for making calls and sending smses
PS seems to be for data connections (When this is selected, the bars are replaced with a circle with a stripe through)
I Could be wrong with the above, so anyone with experience please shed some light
Those 2 work seperately, but when CS + PS is selected, none of them work? Very odd, anyone know what the issue could be?
anyone?
hi. i just got this phone in the states before coming down to panama. it is verizon, but i called them and they gave me the code and now the phone is unlocked....but i can't get coverage here in panama. i've tried sim cards from a few of the local operators and none of them seem to work. i sure hope someone can help....here's what i've done so far: (oh, pls b patient, i'm a bit of a technophobe)
-unlocked sim. phone gives me sim lock is disabled message....that means i'm good to go, right/
-set phone to gsm only mode.
-software is androaid version 2.3.4
verizon global services told me that everything was as it should be and that the phone should work w/ a local sim card so i'm not really sure where to turn to......hopefully someone here can help. verizon also told me that the phone should work on the frequencies here. i have a claro sim card, but have also tried movistar, digicel, and masmovil. i was told that they use either 850 or 1900.
so, i'm totally stumped. hopefully i'm missing something stupid....btw, tried the sim in other phones (from europe and panama) and it worked w/ them. don't think it's a hadrware problem, but am i missing something? is there a setting change? do i need some kind of software update?
thanks!
update- get cell phone reception w/ gps on
don't know if this will help anyone get to the bottom of this issue, but i realized that when i have the gps on, i get full bar coverage. unfortunately, i can't leave the app on in the background. this makes me think it could be a hardware issue....bad antenna? anyone have any ideas
Same problem
I have the same issue as OP. Got my phone sim unlocked, and it runs on SenseMOD-2012-05-18-225643 Android 4.0.4.
For once I did a factory reset, skipped verizon activation (can´t do and won´t work because I´m not in the USA and do not have a verizon SIM or service), set my network preference to GSM/WCDMA, and the network wasn´t working.
Rebooted, my network is identified as soon as it starts, but then it goes to "No Service". Try to search for network but my carrier does not appear.
Any help?
EDIT:
Playing around with the phone, setting GSM as your network and restarting the phone let me make phone calls. No internet though and the APN was configured correctly. The "E" symbol for the internet blinked once in a while, but never got service.
Also, playing around some more, got my phone to not recognize the network again by removing the SIM another time. This sucks.
I have tried everything but in vain ,I rooted this phone via the method described on this forum and worked through version 5.1.1 unlock boot loader and root and installed any custom rom but still on the network bar an X and checked the fone still says on CDMA. I need to Kow from the developers any chance to make this fone work on 2G or 3G GSM network band 900mhz and 1800mhz ,if yes what do I need to do to achieve this ,please guide me as this fone when it came first it was working on 910F version 5.0.1 firmware while in ODIN it was 910v until when I typed *#9090# when it started the problem when I wanted to update it. I WOULD NOT MIND TO BRING IT BACK TO THE WAY IT WAS BEFORE WHEN IT CAME TO ME AS LONG AS IT WORKS ON GSM NETWORK. RIGHT NOW I FLASHED THE ORIGINAL FIRWARE ,FONE BOOTED BUT WHEN HARD RESET IT SHOWS DM VERITY FAILED AND IMEI IS CHANGED, I HAVE Z3X ,OCTOPUS,ASANSUM, AND CHIMERA TOOL TO HELP ME SOLVE THIS. PLEASE PLEASE GUIDE ME
The N910V covers the 900 and 1900 MHz bands natively so that's not the problem. In fact, to use the N910V - just to be clear, that is the Verizon model of the Galaxy Note 4 so make sure that's what you've got 100% - can use 2G/3G modes without rooting or any customization of any kind because it's factory unlocked so the only reason it wouldn't work would be either a) there's a defect in the phone itself (after it's been factory reset) or b) there's a defect with the SIM card reader, potentially a broken pin someplace in the slot and that's somewhat tough to troubleshoot or repair simply and would require replacing the entire reader or perhaps even c) you're missing the APN data that is absolutely necessary to ensure things are going to work properly. From a technical standpoint the APN data isn't necessary for basic network connectivity aka making actual phone calls or receiving/sending SMS messages but it is absolutely necessary to get the data connection working for Internet access.
I would suggest you do this:
- put your SIM card into the phone, whatever one you're hoping to use for cellular and data service, I'm hoping you understand that the SIM card has to have active service on it - and I'm not talking about the phone itself: if your intention is to use the N910V with a GSM carrier then it doesn't matter if it was ever activated or not with Verizon because it's a carrier unlocked device
- find the N910VVRU2BPA1_N910VVZW2BPA1_N910VVRU2BPA1_HOME.tar.md5 pure stock 5.1.1 firmware and flash it with Odin (phone in Download mode, of course)
- don't do anything else with the phone except flash that firmware and as soon as it's done flashing boot into the factory recovery do a wipe - the easiest way to do this after the Odin flash is watch for it to reboot the first time which will go right into the factory recovery, as soon as that ends hold Volume Up + Home and it'll reboot right back into the actual recovery then do the data/cache wipe and then wipe cache separately just in case
- let the phone boot up normally, leave it alone for 15 minutes and I'm totally serious here, 15 solid minutes, don't touch it, just leave it alone and let it boot and settle for 15 minutes
- after 15 full minutes have passed, go into Settings - More networks - Mobile networks - Network mode and set it for Global if it isn't already - DON'T DO ANYTHING ELSE, NOTHING, DON'T CHANGE ANYTHING ELSE AT ALL, then let the phone sit for 15 minutes once again
Yes I know you're impatient, we all are sometimes, but this not one of those times, you have to leave the phone alone and let it settle for 15 minutes in the step and if you're not willing to do that you may never get it working like you want
What I've learned over time is that being impatient sometimes works against you and that some smartphones - most notably Samsung models in my experience - take time to get their network connectivity on occasion so you have to be patient here and let the phone handle "business" as it needs to do. Some phones are nearly instant with a connection, others need time, so be patient, have a cup of coffee or soda or water, read a book, do something for 15 minutes and don't touch that phone.
After 15 minutes take a look at it and you should have some network connectivity, at the absolute bare minimum it should be connected to your carrier and you can make a phone call or send a text message or call customer service (usually 611). If you don't have any service whatsoever at this point then go back into the Settings for Mobile networks and set the Network mode to LTE/GSM/UTMS and - yes, I know you hate this but it's got to be done - leave the phone alone for another 15 minutes.
If after this second waiting period for the network connection to happen it still doesn't get a connection for basic cellular use - no data yet, that might not happen till you put in the APN info if that becomes necessary but that's the next step only if you get the basic connectivity working - then there's something broken on the phone. As stated above if the SIM card has service, there's no logical reason the N910V won't connect to the network for making a phone call unless there's a defect in the phone itself, something is broken or something got configured in some manner in your attempts to get it working and you're possibly looking at a phone you might not be able to get working with your carrier.
If you've got basic cellular service working but no 2G/3G/HSPA+/4G LTE service showing (that's the data connection and not the cellular which shows the signal bars meaning you are on the network) then you need to put that APN data in manually since the phone doesn't seem to pull it from the SIM card as expected. That's a step you'll have to take care of on your own as I don't know your carrier or the specifics of the APN configuration which I'm sure you can find at your carrier's support website.
Anyway, give that a shot. Best advice: stop mucking around with all the rooting/recovery/ROMs and get the phone working FIRST on the carrier's network using the pure stock ROM - once you can do that then you can worry about doing all the neat stuff and customizing things later on. If I had to guess you jumped the gun, missed something in all the experimentation you've done so far and just basically been too impatient in some situations and not let the phone settle long enough to get that connection. I've done that many times on some phones and got pissed about it only to discover that when I stopped messing with the device and just left it sitting all by itself that magically the network connection kicked in after a period of time, usually no more than 15 minutes.
You apparently have a lot of smartphone modification hardware and I'm betting if you messed with it you broke it, now it's up to you to fix it.
Hope this helps...
Hello everyone,
I'm having a bizarre problem that no one can seem to fix. I have an unlocked AT&T branded Note 10+. I used it on my preferred service, MetroPCS.
A couple of weeks ago it stopped receiving or allowing me to make calls. The signal showed full bars and everything else worked fine. After attempting to fix it and failing I switched providers and went to Verizon.
Bizarrely, my phone will not work on prepaid vzw but did work on a post paid so I signed up. Everything phone related worked. It was however very expensive.
Seeing my phone work on a network made me think my phone wasn't the issue so I went back to my preferred network.
Now the situation is this: With a metro sim inserted I show 4G LTE icon but no bars, instead it's just a circle with a line thru it. In this state I have full data but now calls and texts don't work. When I try to make a call the 4G icon disappears and full signal bars replace the circle with the line.
I tried metro tech support, they are no help at all. So I called Samsung. They informed me that my device is still locked. That can't be true as I've used it on two networks that weren't AT&T. However, rather than writing them off I went back to VZW and had a worker insert his sim into my phone and it worked flawlessly, just reassuring me that my device is unlocked.
This device, other than being unlocked is unmodified and had been used in a 100% stock state. Is there anyone here who can please direct me to a solution for this issue?
Edit: I have tried switching to new metro sim cards. Reset my apns and network settings. I even tried a full factory reset.

You just proved either the SIM or the account is the issue.

I would agree. I should've included that I have tried 3 new metro sim cards, with the same result.
However, please tell me more about how this could be an account issue? Because that could lead me down a path to a resolution. Thank you
Trying to Configure Note10+ 5G (N976V) with Visible but can not add APNs. The option is Greyed out. I was able to do it with my Verizon S10 that is also not officially supported. Crazy thing is that for about 5 min i was able to use the Visible SIM in my Note and Call and Send Txt until I rebooted the Phone. The Phone is paid off and Im using it on Mint Mobile now but it doesnt Show the T-Mo Boot Logo when I switched SIMs like my S10 Did. Has anyone been able to get this to work. I was told by Samsung that I may need to Reflash the Phone.
i have the regular unlocked note10+ working on visible.
N976V on Visible.
I am having the same issue, the APN settings are disabled. If you get this resolved before I can figure out a work around please let me know. Thank you.

Did you work it out? if yes, can you share how?
As soon as someone has resolved this issue, please update this forum page!
I just upgraded my note 8(on Visible) to the note 10 plus 5g. After i put in the Visible sim card into my note 10 phone, the phone was not working with the Visible sim card. I was connected onto the wifi network at work and I went into the settings to update the APN information, but it was greyed out and could not enter that information into the phone. After a few hours of googling to see if I could fixed the greyed out APN area so that I could actually enter in the programming, I said let me check the phone outside with wifi turned off. I went outside and tried to place a call and the call connected. I was then able to get wifi calling turned on since the phone was not allowing me to do so before. I went back into work and tried to place a call on the wifi network and it worked. I also tried sending text messages and mms messages and they all work. I checked the settings under the APN area and the phone automatically populated the Visible Internet setting but it was also greyed out, but it was working and I was so happy. I am so happy now with my new galaxy note 10 5g phone that is up and fully working with the Visible sim card. So I believe that having the phone connect onto the cell tower signal and not the wifi allowed the phone to pull in the APN information that it needed. I also reset via the setting the network connections while I was outside a few times. Hopes that this helps...
