No service! HELP!! - Galaxy S 4 Q&A, Help & Troubleshooting

Hi.
I have m919 T-Mobile Galaxy s4 but I'm with other carrier (Wind Canada).
I spent yesterday in environment where I didn't had coverage for most of the day, but i haven't gotten it back yet. Sounds really weird as it might be not connected to the fact at all. I have 4G connection active, which means that I have internet, but it keeps 'searching' for service and I can't Call/Text anyone, neither I can receive calls or texts. Instead of the bar at the top showing how good coverage i have it just shows a crossed out circle icon.
I've tried reboots, keeping my phone off for 30mins without battery, taking out sim and putting it back in, changing network modes and resetting APN (all from settings panel).
Have anyone experienced something like that and how do I fix it? It was working perfectly for last couple of months and the phone didn't get any damage yesterday neither.

Well. "I have m919 T-Mobile Galaxy s4 but I'm with other carrier (Wind Canada)". Im not the smartest person in the world but if u phone is locked to T-Mobile, it doesnt gonna work with other carrier if no is unlocked by IMEI for example.

I've unbricked phones in the past, and fixed many devices etc. most of my devices get rooted on the day I buy them. the issue is that sometimes she cant receive/make calls sometimes and 4G data works ok but when the phone switches to 3G or H+ connection data fails along with the ability to call.
the phone used to be locked to o2 but was opened up to all networks. I need help please.

S7 SM-G930V can't connect to Verizon Mobile Data

Hi everyone, so I recently purchased an S7 SM-G930V and I'm having some problems with the mobile data connection and was hoping that someone on here might be able to help me out. I've been heavily researching and trying everything I can find online for 2 weeks now trying to figure out why I cannot get this phone to connect to mobile data and I'm about to give up and use it for target practice.
So here's the story:
I bought the phone from a seller on Ebay (I know I know) and it showed up in flawless condition externally and SEEMED to work perfectly. Upon receipt of the phone, I noticed that my current simcard wouldn't fit so I took the phone to verizon to get the nano sim and have it activated. The guy put the sim in and booted it up but after about 15 min the phone was still saying that it was "activating" so (being in a hurry) I told him that I'd just let it activate and be on my way. About an hour later my phone chimed saying that activation was complete but I noticed that it was showing H+R for a data connection which I believe meant I was roaming? Anyway I didn't think much of it because I was in a pretty rural spot in Alaska and the service was spotty.
Now here is where the problems started. Once I got home I noticed that the phone was not picking up any 4G LTE data at all and was bouncing back and forth between 3g and 1x but wasn't actually connecting to them, just finding them (greyed out). I rebooted the phone to see if maybe it just needed to update the local towers or something but it still would not connect to any mobile data at all so I took it back to the verizon store and they swapped the sim for a new one. Now, the phone will not activate AT ALL. The guy tried 3 different sim cards and nothing. It shows fully connected (5 signal bars) for voice but just cycles randomly between 3g and 1x data and will not connect to them let alone even find 4g lte service. When it connects to the towers it shows Verizon Wireless as the connected carrier but since it can't connect to data, it won't activate. The guy finally told me to call tech support and after about 3 hours on the phone with them, they pretty much told me they don't know what's wrong and to get a new phone.
So I decided to hit the internet and try out every option I could find before just sending the phone back. However, after countless hours of tinkering with the phone including rooting the phone, updating the firmware, factory resetting multiple times, clearing cache, disabling the cell radio and changing settings in build.prop, default.prop, apns_config.xml etc etc and getting nowhere I am stuck. I was really hoping that this was just a software issue or APN/modem/radio band etc issue that I could fix but it's looking like it might be a hardware problem or it's way above my skill set.
TL;DR
Verizon Galaxy S7 will not connect to any Verizon Mobile Data Network and therefor will not activate but it will connect to data while roaming? Any and all suggestions, help or advice is appreciated! Even if it's just to tell me that the hardware is faulty and I need to replace the phone. I just need some opinions from the pros if possible. Thanks guys/gals.

International S8 (SM-950FD) On Verizon

Hey guys,
I bought the G950FD on eBay so that I could root and tweak it the way I always have with my previous phones. I use total wireless which is on Verizon towers and have gotten the phone to connect just like it should, text, receive/make calls, and use data. To do this, I used the Flashable CSC Collection here to switch the CSC to VZW and it worked for a while, but after restarting I started to get some problems that I can't sort out.
1. Calls do not work anymore - I can't make or receive them at all. Dialing a number just says "Dialing" with some zeros below it, and calling my number goes right to voicemail.​2. Data cuts out sometimes and shows no signal. Recently, I tried to search for carriers and reconnect to Verizon but now I can't get a connection at all without restoring a backup.​3. Other observations: Using a signal info app, it seems like I only see band 1 and it is usually very slow. CDMA obviously doesn't work, so maybe that's why I can't register on the network anymore, but why did it work when I first booted up? I can't change the APN settings after switching to VZW CSC and also can't see an option for VoLTE, but that must be working right? Only some ROMs seem to work with the VZW CSC and allow me to connect to the cell towers. Changing the network mode does not do anything and just reverts back to 2G, which doesn't make sense because 2G shouldn't be possible. None of the codes that can be entered into the dialer to run the activities have worked or helped at all. When connected to WiFi, the no signal bar shows 4G connectivity and the signal bars reappear but I am still not connected.​
So, what can I try and does anyone have knowledge to share about cell towers, SIMs, registering on the network, or anything else relevant to my situation? I am completely stumped and would love any input that you guys could give me and future 950FD owners who might have this issue.
I'm looking forward to hearing what you guys know,
Joe
Only verizon phones work on verizon, you can't use a non-verizon phone on its network even if its supports its frequencies. Lte on your s8 is compatible with verizon's but after it worked for a bit they disabled your imei from their network, nothing you can do about it.

Thanks for the reply! I do not think they have blocked my IMEI because I just restored a backup and everything works again. I believe it has something to do with the settings on my phone or possibly a bug with Android/changing the CSC because changing the network settings cause crashes, disconnects, and other weird behavior.

Lol don't give misinformation, they don't do this, in fact I'm pretty sure forcing all users to have phones obtained through Verizon would be completely illegal for a Telco to do. VZW doesn't even know what type of phone you have unless you register it and even if you do they don't care.

Moto g5 Plus Verizon issues

Hello. Moto g5 plus unlocked 32 gb from amazon, no prime ads. Unlocked bootloader, custom Validus 8.1 rom and TWRP recovery. Was previously with Redpocket Mobile, switched to Verizon prepaid ($40/month plan) and received my 4g LTE sim card yesterday and have been having nothing but problems since then.
TO start, the sim took a long time to register my number, and "program" itself as Verizon called it, this is because I finally figured out even though Verizon claims excellent coverage in my area (49783 U.S) I currently have barely any service, so that's why it took forever to register/port my number over.
SO now I can hardly even send a text with the stupid thing, it's resting on 1 bar and then usually disconnects frequently and says "no service." When I go into town I get 3/4 bars of 3g , not 4g LTE. I was curious as to why this happens, so I spoke to a friend who has Verizon in my area and he said it's a deadzone for verizon where I live, but that he gets 4g LTE everywhere else in the city.
Does anyone here have a Moto g5 plus US version (no indian/foreign versions) PURCHASED in the US and on the Verizon network? Also, my friend is on postpaid network, not prepaid, not sure if that makes a difference. IF anyone's with Verizon here can someone confirm it's compatible? It shows up on my Verizon account as XT1687. I got this plan for the extra data and rollover/hotspot capabilities that redpocket DIDN'T have, but if I can barely even send a text message at home what's the point? I have been on the phone with Verizon for hours and they claim my phone is compatible but that they "cannot guarantee coverage on phones not purchased from them" or something like that. Does having a custom ROM affect coverage in any way?
Couple more symptoms to help you guys diagnose my issue: In settings > about this phone > sim status, when I click mobile network status it usually "refreshes" so if it had listed one bar previously, I tap on it and it will say "no service" which to me indicates tapping on it updates it, and that the phone is constantly losing signal. Also, I keep getting messages about leaving service and roaming, though roaming is turned off.
What I'm most intrigued about is I can make calls from anywhere in the house unless the phone says "no signal" so even if the phone is on one bar and listing x1 for service or 3g, a call will come in or go through fine, but MESSAGES WILL NOT SEND. In android messages, it says "tap to send again." Which is weird because if a call could go through certainly a simple sms would?! I still have yet to test service in the heart of the little city I live in, I've only been outside of my house and in, so I haven't extensively tested different areas yet, so I'm not giving up yet!
Finally, what APN should I use? It's set to "straight talk verizon" right now, but there's a bunch listed. Perhaps other Moto g5 plus users could confirm which one they use? I suppose it sets itself by default...
thanks for looking through and please answer my questions! I need more competent help than Verizon can offer.

G935U No Service

Okay so I have been fighting this phone for months now. I am so ready to just sell it to some phone trade-in company for $175. I am at a complete loss.
My father-in-law ran over his SM-G935V (yes, Verizon) with a golf cart and broke the screen and back plate. He then gave me the phone so I could fix it and use it. I replaced the screen and back cover on it and ordered a verizon sim card (I was on straight talk BYOP program using an ATT sim card) I activated the sim card and it didn't work on this phone. It just said, "Searching for Service". I put the sim card in my Moto X (Pure Edition) and it worked fine and had full signal. I took it back apart and made absolute sure that the antenna and every other connectors that I unplugged were seated and connected properly.
Seeing all the verizon bloatware and that it was on 6.0, I then thought it may be a software issue so I decided to get the G935U 7.0 factory unlocked image from sammobile.com. I waited for like 4 hours and downloaded both the unlocked version and the Verizon version. After using odin to flash both of them (one at a time of course) neither worked . The flash did work perfectly in every other aspect and the phone is now a G935U. I still have the original problem, however, where the phone shows "no service" and wont connect to a cellular network. It auto configures for what ever sim card type I put in (verizon, ATT ect) and connects to Wifi.
I'm so done with this thing.
Any suggestions?
Thanks guys!!
I have the same problem, I haven't find any fix to this error...
I didn't have much money into the phone so I sold it on one of the phone trader websires for $180.
Case closed haha
No service message
I'm using smg935v with straighttalk byop sim card.. every time I restart my phone it says searching for service.. no text messages or incoming phone calls can be recieved. However, if I open the phones dialer and attempt to complete any dialed number.. Verizon wireless reappears and full phone functionality returns. I realize this is way late on your post and this probably doesn't matter.. but this may help anyone else experiencing this issue in the future.
I have a Verizon Galaxy S7 Edge G935V. I use it on Straight Talk with the AT&T sim card I took out of my Nexus 5.
I had to go into the settings and change it from CDMA to GSM. There is another choice called Global.
I tried both GSM and Global with same results.
Next I went into the APN settings and added a new APN. I entered all the information required for Straight Talk.
The phone is working fine except for 2 things I noticed. The verizon s7 Edge is missing LTE Band 17 and I think 12 too.
In my area Band 17 LTE is what my nexus 5 would connect to verified by an app called LTE Discovery available on Play Store.
On the S7 Edge it doesn't get Band 17 LTE. Fortunately I can connect to another band but its not quite as strong but it works.
I can surf, text and send pictures. When sending pictures I noticed the messenger program (default) isn't reducing the size of
the pictures small enough to work with text messages. I struggled with this for a week until I tried an experiment.
I used an app called Photo and Picture Resize. The App lets me take a picture, resize it and then send it with the messenger app.
Once the picture was reduced it sent fine. My nexus 5 never had this problem.
The other thing I noticed is sending a video text results in terrible quality. I have tried the lowest resolution
to the highest resolution setting with no improvement. I did a search on this and others seem to have the same
problem with the other versions of the S7 Edge, S8 and S9. I would like to find a fix for that.
The straight talk site offers the correct APN settings should you not know what the are.
