Does anyone know if an unlocked 8525 will work on Verizons network? I've been using it on Alltel and Verizon bought them out now they want me to get a new phone. Sure hate to give this one up.
If the sim unlock has been run the there should be no reason why not...
Mind you I'm in Australia...

CDMA vs GSM
I went back and forth on this one. (and Welcome!!!!!)
Verizon here in the states is a CDMA (EVDO) system that doesn't use sim cards, GSM systems does. This relates to how your phone communicates on the network. Now willl a GSM phone work on a CDMA network, i think that it will. The SIM card in GSM phones supply the network with your PIM to access the network, it is tied entirely to the network not the phone. CDMA requires action from the carrier, and your access to the network is tied to phone not the network. You deactivate one phone first, then activate the second. You'll probably need to supply your IMEI to verizon and they'll load your access. Just a guess though, cause I've been with cingular/at&t since i carried around backpack sized mobile phones.
Does anyone know better?
As far as I know of, no. I don't believe it has a radio for the CDMA. Although you state you have used it on Alltel which I thought was CDMA...
What reason did they give for wanting you to get a new phone?
I recently bought a TMOUS HTC HD2 and unlocked it to use on my AT&T network. However after unlocking the phone and trying a few roms I still am unable to connect to my AT&T network. I did unlock the phone on the stock winmo rom. And when I say i cant connect to the network I don't mean internet or mms. Not a single network function works, that includes calling, texting, mms, and internet.
Any help would be very much appreciateed. :fingers-crossed:
got any other sim cards available to try? (unlocking unlocks to all networks)
SIM cards
Well I have some old Tmo cards that I have from my old Tmo account. And I have a few other AT&T cards that are activated. Currently I have used one of the Tmos cards and one of the AT&T cards but they both do the same thing. It is rather frustrating. Do you think I am not picking up any of the EDGE signal the phone needs to work?

no, its not that, edge is just a manipulation of the 2g network, there is no 'edge signal', there are only 2g or 3g networks (simplified, and not really accurate/true, but close enough for this purpose)

have you EVER seen it working? id be tempted to think it was broken / blocked.
No I did not check before. Isn't there a way to tell if it is blocked with the imei number or something. I hate to think I bought a bad phone. If it is blocked is there anything I can do?

not sure, sorry. I'd maybe give at&t / tmo a call, see if they can offer any advice based on the imei.
Thank you for your help. One more thing the siginal bar at the top shows I have no signal but it has an x over the bar indicator. (I'm running gingerbread sense) When I drag the top bar down it says no service. Would this happen with a blocked phone?
No clue, sorry,
I dont know if anyone else has tried this but i popped in my tmobile sim into my uscellular g4 and had service the only thing i had to add was the apn
This is without a sim unlock bought the phone 2 days ago and been using it was going to get a sim unlock but apparently it works just fine without it on tmobile.
Just to show that its a uscellular g4
Are you getting full speed LTE?
Yes doesnt seem to be a problem only thing i noticed is it wont let me make calls and or text but it will let me use data
When i make a call it tells me its an incorrect sim so i think if i unlock it will allow me to make calls and texts but as i said previously itll let me use data no ptoblem
I had heard that some CDMA phones may not allow phone calls or texts, you should look into finding a way to disable the CDMA, it may or may not work.
I think calls and texts are going through the CDMA and not GSM.
I have to agree i think if i sim unlock it that it will allow me to bypass the cdma part of the phone uscellular said after i pay the phone off i could get the sim unlock for it
No need to sim unlock, it already is, most new phones from verizon are already sim unlocked and some other carriers as well, only help is probably trying to disable the CDMA in the hidden menus and probably enabling gsm.
I agree with @Arctic Prodigy, you should be able to make calls texts, just by changing something in Settings. On my One Plus for instance (the only device I have handy, sorry) go to Settings > Mobile Networks > Preferred Network Type and then change from CDMA or whatever it is set to, to GSM/UMTS or something similar to that if it's available. To reach this menu on your device it may be slightly different in Name or location but it should be there somewhere. A friend of mine had a VZW s4 and I told her she could use a straight talk sim in it. She had issues at first but I do remember I changed this setting I mentioned above from whatever form of CDMA setting it was on to GSM and it has been working fine ever since!
I would think if it were sim locked, then you most likely wouldn't get data after setting Apn. This tells me it sees the tmo sim and that you have active service, so it is allowing phone to use the data connection.
Hope this helps!
Sent from my A0001 using XDA Free mobile app
It has these and i changed itto global and gsm/umts and still vouldnt make calls or texts
It tells me when i make a call its an invalid sim even after changing it to global or gsm/umts
But like i said it lets me use data so ill have to do some digging i used to dev for the note 4 so ill have to learn lg's a little shouldnt be to hard
I know the T-Mobile iPhone 6 has CDMA as well but it is disabled, regardless of changing in the settings to gsm/umts it still maybe trying to go through CDMA, you need to disable CDMA and enable gsm in the hidden menus and if you get it to work that way you may need to reset it if you reboot phone.
The problem is i havent been able to ascess the hidden menus ive tried all the known lg hidden menu codes
I am positive it will happen soon, I have seen a posting somewhere here for the hidden menu but it still might not be accessible just yet, but a developer will get it soon enough, I know for the LG G2 or G3 the CDMA phones all have been patched to get gsm. It's only time now.
Well if i can put a few heads together that have a uscellular G4 im sure we can access the hidden menu for the uscellularG4
Try 277634#*#
Also found this link http://androidforums.com/threads/how-to-turn-4g-on-off-access-hidden-menus.638374/
That doesnt open anything at all for me
It seems to be working only on some of the G4's but not all.
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.

Does it say Sim not present? If not, go online and search for APN settings for whatever network your on and enter them in as listed. On the screen you posted, click "access point names" and transpose the data from whatever your carrier's APN settings.

Can you raise this in guide section ->uicc unlock post. you can ask for modem partition from someone who has openus variant and can flash those ones. Did you also check your sim in another phone

Maybe i dont understand but it looks as if you have 2 APN settings profiles yet you don't have either selected.

I glanced at these but didn't read the whole threads. Pretty sure they address sprint sim card locking post update. It may be worth reading about to see if yours is a similar situation. Good luck man.
I'm kind of in the same boat, essential phone openus variant with no service. I've tried different things and have been able to get it to work but just for some time before it gets no service again or some odd behavior. I don't get invalid sim or no sim notification, it is a no service notification, apparently it recognizes SIM and accepts it but is not able to find a network, as if it were out of coverage or mobile radio off. SIM card has been tested in another essential phone at same location and works flawlessly.
So far I've found that if I downgrade software to nougat and then update to oreo or pie, and then insert SIM, phone is able to get LTE connection, receive or make calls, it works fine. But then after a couple of hours or even half a day, it gets no service again. Network or factory resetting doesn't do anything, changing network settings neither,then after If phone is restarted with sim in or if sim is inserted while on, it immediately shows voicemail notification but there is no way to retrieve it of course.
Most of the times at network settings it gets and shows the correct apn but it doesn't let to choose network manually, it turns back to automatically and says no networks available. Some times I get a rare relation with wifi connection, if wifi is on and connected it shows carrier name as if ti was connected to network but no calls in or out, as soon as wifi is turned off or disconnects, carrier goes back to No Service.
Maybe someone knowing this has some idea of why phone has this strange behavior which makes it useless as a phone.

I think your phone locked for Sprint like mine , call them to unlock it .
mine is unlocked From Sprint now , but i sill need a Sprint Sim to complete the unlock process which i didn't get yet , I don't know where i can get one (I LIVE IN MOROCCO)
I guess it's possible but I really don't think that phone could be locked to sprint. I understand although sprint variant is supposed to be locked, most users are able to use other carrier sim, and only the pie update has shown invalid sim, which is not this case by the way.

mine is not a Sprint variant , and somehow is locked to Sprint , it was previously purchased From Best Buy . but after installing Pie on it , it shows no service , i called Sprint and they said it's locked to them
than i made an unlock request and they unlocked it
ok, so maybe flashing modemst images for openus variant could solve the problem, I don't mind trying if they come available but haven't found them yet.
