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

I've been using an S4 for about 2 weeks now, no problem. Last night I realized a text I sent never went through, and today my lock screen says "No Service" or "Searching" (despite the device showing full signal). I can't send/receive calls or texts, and I don't use a data connection. This SIM is also new (~2 weeks), and the device is neither rooted nor running a custom ROM. I've tried everything I could think of, like:
reboot
pull battery and SIM
confirmed APN settings on t-mobile site
tried alternate, non-"LTE" APN (epc tmobile com)
tried every network mode setting (GSM, GSM/WCDMA, etc.)
reset APN to default
turned on mobile data connection
manually scanned for networks (wouldn't connect to AT&T or T-mo)
select network automatically (wouldn't connect)
complete factory reset
I tried my SIM in another T-mo phone and it works; tried a different SIM in my S4 and it doesn't work. All other T-mo phones in my household are working fine. My S4 is definitely the problem here, but I don't see how the radio would just stop working after 2 weeks.
Has anyone else experienced/seen this? I never have, and it's driving me up a wall. I'm going to try my local T-mo store tomorrow, but I was hoping to fix it before then. Any help is greatly appreciated.
EDIT: I purchased the phone new on ebay. For a minute I thought the seller might have reported the phone stolen, but I checked the IMEI and it's clean.
Ive experience this but my service came back in about 25 minutes I did reset reboot battery pull sim pull it just came back on its own
Unrooted Samsung Galaxy S4 Up and Running
Rooted Mytouch 4G Slide retired
Rooted T-Mobile Sidekick Touch Obliterated
Rooted Mytouch 3G Slide Lost
Rooted T-Mobile G1 Dead
So I finally got to T-mobile today. Unfortunately, my hunch was right: the IMEI is blacklisted. Their in-house system must be more up to date than their web IMEI checker.
Time to solve this issue elsewhere.
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.
Hey guys, just unwrapped my new N5x and popped in my sim card. Yet for some reason I can't make or receive any calls!
Calls to me go straight to voicemail, and when making an outgoing call it either immediately says call ended or after a while says network unavailable.
The strange thing is that the entire time I'm connected to LTE (full bars) and data works fine (I can use chrome), and I can even send and receive SMS!
It's been like this straight out of the box. I reset the network settings, then factory reset the device, then upgraded to 6.0.1, rinsed and repeated with no luck.
Probably related: I tried setting the phone from LTE preferred to 3G or 2G but it still says connected to LTE. Even did it manually from the *#*#4636#*#* and nothing changed.
I'm using HOT Mobile in Israel and the American version of the phone. All bands are here are supported.
Any thoughts on how to proceed?
Do US specifc models of phones normally work fine in Israel?
I know I had these symptoms when I managed to accidentally swap my UK model to use USA bands. Only potential difference is that I don't think SMS worked for me.
If someone more knowledgeable knows where the "Network settings reset" pulls values from and to, that might help.
Or which partition holds the data that makes a US phone a US version and an EU phone an EU version (assuming it isn't hardware), we could potentially flash stuff.
Yeah they do. I have a friend with a 5x and his phone is working fine. :/
Check your apn settings, re add them again to test.
Maybe your network do not support lte calls, try it on 3g. This was my solution even thought my network supported volte and worked on s6 but not on my 5x.
I see you tried the 3g option, my problem was another app causing the conflict between lte and 3g. Able to source for another spare sim to try?
I deleted the apn settings - no luck. tried 2 different service providers and same results with both
I havnt installed anything yet and wiped the phone to be sure. Could a stock app be causing the conflict? How can I check?
did you try having your friend put his sim in your phone and yours in his to see if it works?
Yep - he's on the same service provider that I am. Didn't work. Also tried a Sim card from a different service provider.
Here is a solution if you still need it http://forum.xda-developers.com/showpost.php?p=64023143&postcount=10
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.
So I have the Galaxy S9 plus, sprint edition. I flashed it with the U1 firmware. Then paid to have it network unlocked. It was reading every SIM card, but sprint & boost (bcuz to get are n not compatible with the unlocked SO/S9+.
So, I decided to switch to either Verizon or AT&T. Verizon won it due to the year long Subscription. Anyway before I went to Verizon. Every SIM card I placed in the card worked no problem. Well, Verizon activated the phone told me the steps to do. I powered off the device. Like I was told & placed the new sim card in.
When I booted up my device it, rebooted with the "New Network provider Sim inserted" & did so. It came on with service. Then rebooted again & came back on with service... Yet again. Then out of nowhere it rebooted, but this time it came on with it any signal bars. Saying, the folowing messages "Searching For Service", "No Network Connection" and "Emergency Calls Only".
I have did all the trouble shooting that I have came across. Including using the Chimera Tool to try & fix the network connection. But it repeatedly failed. I took it to UbreakIFix & they said the phone's fine. That it has to be Verizon's side with the problem. Can anyone help me fix this issue.
I have placed other Sim cards into the device & they work but not one Verizon Sim will.

some steps would include making sure its switched to global mode in network settings and setting up the apn
