I have bought my partner a Samsung Galaxy S5, The problem is something I cant get my head around. 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.

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.
"Unlocked" Verizon Samsung Galaxy S4 to Tmobile switch - cannot send text messages
Please! HELP!!
I switched from Verizon to Tmobile and my stupid phone updated to Lollipop 5.0.1 and now I can't send text messages without calling Tmobile and having them send a signal to reprovision my phone EVERY time after it reboots (which I have to do EVERY day now that bluetooth sucks so hard and randomly stops all the time in Lollipop).
Before I accidentally hit the button to update, my phone would show my Verizon voicemails waiting in the notification area and say "No Service" until I called my voicemail and let it disconnect, to which effect it would seem to go to no signal to nothing to HSDPA to plus to 4G LTE and BAM! I'd be on Tmobile able to send texts and all (before which I could NOT send texts, but COULD receive them (IIRC), and make phone calls (WITHOUT dial tones being accepted (which seemed to be fixed in Lollipop by selecting long press tones in the phone settings), and I COULD browse the web, etc.).
NOW, that little workaround does NOT work anymore and I have to call Tblowbile to send that magical signal to my phone (which doesn't seem to take all the time for all people for some reason).
I DO have the APN entered correctly (as stated on their website) and setting the phone to and from global to global/lte/gsm and selecting tmobile as the mobile network in the settings does NOT work.
I GUARANTEE it is that stupid GRAYED OUT Verizon APN that I CANNOT remove that is causing ALL these problems (given the nature of the phone post-reboot on KitKat).
PLEASE, tell me how to delete that stupid VZW APN or how to downgrade to KitKat or of another workaround other than having to call the deceptive, bait and switch company that is Tmobile EVERY time!
I'M DESPERATE!
PLEASE, HELP!
You can't. The bootloader is locked on Verizon, which prevents root. They've also apparently blocked access to the APNs in firmware.
Your options? Head to the XDA Verizon S4 forums and check out their various guides.
P.S. T-Mobile is not pulling a bait and switch here. They are providing you with service, which is what you paid for. They have no control over the OTA function of the device. Unless you have proof that T-Mobile is baiting and switching, your comment is slanderous/libelous.
Hello,
I have had this issue off and on over time. I have the Unlock Verizon S7 edge on the Verizon network.
Sometimes when I use the phone I can do all functions normally while on a call.
Sometimes I'll do the same and the data is completely gone I will get no 3g or LTE on the phone while on a call. Once I hang up all the data will come back and this will continue with any on going calls until I restart the phone.
Only suspicion I have is it has to something with Pokemon Go after I use it. But can't confirm.
Anyone else having the same issue ?
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.
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.
