Possible modem failure.T-mobile was not immediately helpful

Much to my dismay, I think device is dead, bit I was more wondering if anybody else has run into this at all. To preface I'm currently traveling in Europe, phone worked fine from the 17th of October. I have the International Data and every thing was peachy till last night when it stopped associating to the cellular network. I had been using wifi calling to home till I started getting the red wifi calling icon saying invalid sim. I started looking at settings and noticed APN settings we gone and it couldn't search for networks.
I tried restarting, puling sim, then I tried a factory wipe, ultimately culminating in the pictures attached below. I also attached a picture of the bootloader for added info.
I called into T-mobile, 5 representatives and an hour and a half later was told that the only way that I was going to get a replacement is to go return it to the store where I processed my pre-order, and that needs to be done within 14 days. I'm going to try today to see if Samsung can do anything for me, but this seems more of a hardware failure that should be covered by the manufactured warranty.
I do have JUMP but I don't feel I should have to pay the deductible for this.
:TLDR:
I've not rooted, flashed or other wise modded my phone, anybody else run into this?

If you traveling I think phone needs an unlock code and a different Sim card. WiFi calling probably just updated it self and kicked you off.

You don't need a new sim to travel with. I've used my sim and carrier many times in UK and Germany with out issue, you just get to pay a premium for roaming.
If I wanted to use a local carrier and then the local rates, then I need to be unlocked and then a local carriers sim.

Note 8 keep dropping connection once a while. Cannot call, text, data.

Hi! Thanks for reading my problem.
I have a tmobile note 8 that I have successfully switched to verizon firmware according to the guide here. It got the verizon boot logo and bloatware just like vzw phone.
It work perfectly after the switch, 4g lte ,call or text all work.
But it will drop after a while of use. It can be a few hours or few minutes. I cannot receive call, cannot access internet, cannot make call...
If I restart it all will become working again for a while. Any recommendation how to fix it? Thanks again.

I have a note 8 (SM-N950F/DS) for about three weeks now. I am using FP on AT&T network. When I just got it, especially while I was moving in the car or train, it would lost the data connection quite often even though showing full bar signal. I had to put it on air plane mode then switched back to reconnect.
Then after 1-2 weeks of use, the issue went away. I don't know it was due to the latest update (I am on Dec security patch now) or some kind of the phone learning my travel pattern.

Interesting, My phone lost it while I m at work... not even moving

For the longest time I thought was alone here. VZ Wireless Note 8 user here. My signal also just drops out of no where. When I look at my screen the 4G LTE upload up arrow is the only one turning up and down. Sometimes this issue will go away on its own after a few minutes or longer. But, randomly out of nowhere this started to happen. Few weeks now and counting I'm guessing it has something to do with a update that I recently upgraded to. I never had this issue when I first had my phone.....

I also have the problem.. Also Verizon branded Note 8.
I see a global Android update coming to possibly address this
From Android Headlines (AH):
"New Android Update For Galaxy Note 8 Improves LTE Stability"
"The latest Android update for the Galaxy Note 8 was designed to improve the stability of the phablet’s 4G LTE functionality as it specifically addresses a bug that occasionally caused interruptions of such connections, as revealed by a changelog published by Samsung earlier this week. The update appears to be rolling out on a global level, with its distribution officially starting on Wednesday, 15 days after the Seoul-based phone maker launched the latest security patch for the same handset."
Starting this month..
Anyone with ideas how to resolve this in the meantime?

I am still having this problem after oreo update.. I don't think I want samsung anymore..

Ok guys those who have Verizon, go to settings, mobile settings and change network to cdma and reset your settings. Turn off the phone, pop the sim tray out, power up ur phone while sim is out and turn off the phone again, this time push ur sim card in and turn on your phone. It should solve the problem of signal being dropped. Good luck.

US Cellular Note 9 no longer updating on AT&T?

Back in July I got a steal on a new US Cellular Galaxy Note 9, so I immediately threw my iPhone 6S SIM card into it and went through several rounds of software updates. After the last update the splash screen switched to AT&T and it suddenly had several AT&T apps. It didn't TOTALLY eliminate the US Cellular stuff because I had to delete at least one app and change the Samsung browser's default home page.
Due to the iPhone SIM card and some stuff on AT&T's side, it would not do VoLTE or WiFi calling until I got a new SIM and had AT&T use the IMEI from an AT&T Galaxy Note 9 (read it off one from the store). I did that in late August and the only remaining issue O noticed was that my MMS messages will not download as long as I am on WiFi.
I just noticed what may be a new issue: I think I stopped getting carrier updates. Looking on AT&T's site, I see that they have multiple newer updates with the latest from September 18th:
https://www.att.com/devicehowto/tut...tep_KM1278532?make=Samsung&model=SamsungN960U
My "Security Patch Level" says May 1, 2019, while AT&T's website says that there have been 4 updates since then (latest at Security Patch Level September 1, 2019).
My baseband version doesn't quite match any of the ones associated with AT&T updates, though their May 22nd update seems to be the most similar (AT&T's N960USQS1CSE1 compared with my N960USQU1CSE3).
I recall that the new phone updated multiple times and was still on Oreo before it updated again to Pie, and again to AT&T-flavored Pie. I figure the final update was really just adding the AT&T apps and splash screen, but it somehow stopped me from getting further updates from US Cellular. I'm pretty sure I had an AT&T SIM card inserted for all of my updates.
On that note, I believe I tossed the original SIM and US Cellular does not operate in my region (only showed up here through a salvage store). I'm not easily able to get another US Cellular SIM for triggering it to revert to a US Cellular ROM. I'm not interested in custom ROMs and all that and ultimately just want to keep my phone up to date the same way a normal AT&T customer would after buying theirs from AT&T. I thought the Note 9 adding carrier customizations to match the inserted SIM would take care of all this automatically (half the point, right?) but I guess I was wrong.
Is it possible to get carrier updates like I was getting before? If not, what would you guys recommend for getting up to date and staying up to date? Thanks!

I'll check it out when I get back to my PC. Thanks! I assume it's something I need to flash with Odin?

Question Anyone Have ZenFone 8 on Verizion?

it looks like it has the right frequencies to operate on Verizon, and it will initially connect to the network on boot, but then drops off.
Any ideas here?

Hi - Mine arrived over the weekend and I put in my Verizon 5G sim card and i was able to connect to verizon data network. All things data worked.
But I can't place or receive calls as volte isn't working (my account has volte active). I don't have 5G where I live - so I'm on the LTE network.
I opened a support case with Asus this morning - they said to wait 24 to 48 hours for their engineers to review it. They originally told me to call Verizon, which Verizon told me they can't help. Verizon said Asus has to work with them to get the phone certified. I'm not sure what to do at this point except wait for Asus to reply. I will be returning it if they don't get it sorted out very quickly.

Out of the box I had data only without ability to make calls. After rooting the the phone and installing LineageOS I was able to make calls and and operate the phone on Verizon network without any issues.

Can anyone confirm this? And if so, why does LineageOS work, but not the default ROM?

I just tried it and it depends. I had the exact same symptoms:
- Data worked fine
- Texts works fine
- Calls didn't work at all
And I installed lineage 19 and then everything is normal and great. No idea why though.
EDIT: I installed lineage 19, staxisos, omnirom and all had this problem:
- Data fine, calls, fine, texts could send
- Couldn't receive texts.
After the level 2 verizon tech told me the phone was a loss I returned it. Now after doing a ton more research I found out that it might be because I simply took the sim from my old pixel 4 and popped it in. It seems you need a new sim card or you need to somehow have your line switched to be "cdma-less". Looking at these articles:
r/verizon
r/SonyXperia
OnePlus community
The guide presented on the oneplus community gives me hope I could still use this phone with verizon, but it appears to be a daunting task. If anyone has navigated the customer service and succeeded with this specific phone, I might rebuy it.

Samsung Galaxy S10 - Unlocked Phone (AT&T Blocked Call Issue)

So many people are reporting with the 3/1 sweep by AT&T, that they are blocking almost all Unlocked phones: See: Downdector Link We personally have a S10 (G973U1). AT&T is saying on this list: AT&T approved phone list that it is supposed to work. But like many other people "calls" end immediately, but we can text and data work. It is some sorta ploy by AT&T to force us to upgrade our phones. They want us all to upgrade to S22s. Anyway I was ranting. Anyway, if you look at that link, they are saying that the phone has to be on the latest software. The last update from AT&T or the manufacturer was in January. I checked the firmware site, and Android 11 is the latest in January. I'm wondering if there is some hack to get us on to '12' or something. An update might solve this issue. We know that a new SIM does not work. Calls seem to be rejected on the network, just based on the phone model or Android version.
We are aware that a version 12 is out there for the phone, just that firmware is not for our US-unlocked model yet. But maybe it can be hacked?
Edit: It appears this thread may be linked with this older one... But it is ever more pressing issue now:
S10 Unlocked phone with AT&T Firmware here they explain how, and the problems with flashing. This was back in 2019, so I'm not sure if this will still work. Even then it didn't work for everyone. Some in that forum claimed that it did. AT&T seems to now be blocking from their calling network any phones not enabled with VOLTE and the extended AT&T services that are not present in Unlocked phones.

I was helped by a user to achieve ascendance onto the AT&T network. I'm not sure if I'm to reveal his name. We 1) go into Developers mode on the phone. 2) Hack the Kernel. 3) Flash the rom to the G973U (model)... with the AT&T firmware. So that the Wifi-Calling and 5G features would work, and AT&T would allow it on their network.

I've literally been searching for an answer to this for days now. My wife and I have S10's. I work far from home so I really need her phone working in case of emergency. Can you please point me in the general direction? Thanks!

Agreed, I didn't know such a thing was possible, but I'd love to hear more about this!

At first I had to use the Samsung Band Selector app from the Play store and go into More Network Settings > AT&T > Preferred Network Type and choose 3G. Unfortunately this killed LTE so all data and calls were going through H+. As I was mostly on wifi I could live with it since I could actually use the phone again.
Then Friday morning I checked for updates and there was the update to take me to Android 12. I took the update then when it finished it said it needed to reboot to connect new SIM to carrier services....it wasn't a new SIM. I let it reboot and everything was working with VoLTE again.
Hope this helps.

I appreciate you getting back to me. Unfortunately I am still on android 11 with a custom ROM and also this is a global phone so that app didnt work for me. I dont receive OTA updatez. I'll update to a new ROM and see what happens. Thanks
