Hi All,
I was wondering if I could use my unlocked 8525 with Verizon's net work if I switched to them? I'm not sure about compatability of the phone with Verizon's voice and data services and was wondering if anyone knew.
Thanks
I dont think so. Att and verizon use two different technologies. Att uses GSM and Verizon uses CDMA. Im almost certain tho a phone that is based on GSM cannot be used on a CDMA network. The phone will work on TMobile or USCellular. They use a GSM based technology. Verizon Sprint and Nextel all use CDMA. If i am wrong and you can use the GSM based phone with Verizon CDMA then someone please correct me. But i am pretty certain you cannot.
OK,thanks. Thats what I thought
Verizon does not have sim cards, is that correct?

Not that I've ever seen.
I know sprint phones have sim card slots, but they are not used, at least in the USA.
My guess is that CDMA phones can be used in the same way as GSM phones as far as switching sims to use different carriers, but the CDMA carriers in the 'states don't use that functionality (probably to keep a tighter grip on their sucke....customers and wring more money from them through phone sales/upgrades and extra services, like a data service to put on extra ring tones )
I know that I don't know much about these phones, but what of the setting inside of Settings/Personal/Phone/Band where you can select WCDMA as your network type? I've got an 8525 and it shows as an option, but I just don't know if anyone's tried it before.
CDMA and GSM phones are totally different. The only SIM based verizon phone that Ive seen its the Blackberry 8300 its world edition soo it can bu used through a cdma and also a GSM carrier. I would be interested if anyone knows how to say make a sprint phone capable of being on verizons network. That would be something different.
actually a sprint phone is capable of being used on verison network any cdma phone is. in short the way cdma works the subscriber info is assigned to the phone's esn by the carrier so only the carrier can change your phone with gsm the sim (Subscriber Identity Module) holds the subscriber info and it is assigned to a sim card id not a esn (electronic serial number) so all you have to do to get a sprint phone to work for verizon is get verizon to let it (GOOD LUCK WITH THAT) you would have better luck the other way around verizon is the pickiest co out there when it comes to network integrity and security issues they seem to think that letting people use any phone they want could somehow hurt their network

WCDMA is 3G. 3G on GSM systems is essentially a CDMA standard, but not the same CDMA as Verizon uses. It is not compatible.

Has anyone who bought the g4 play Verizon version noticed the unlock policy says either use the phone for one year or make $75 in payments? I'm wondering if Verizon actually unlocks the device will it enable the 3g bands they are there but they're blocked. Has anyone actually had Verizon unlock this device?
How do you know that the 3G HSPA+ bands are present? The specs I've seen only list quad-band GSM, dual-band CDMA, and LTE bands 2, 4, 5, 13.
Ohk I got my Moto g4 unlocked and I actually got it to dial out the problem is I think because my phone is still on it kept taking me to Verizon my service was T-cdma and I couldn't find where I could input APN settings

I got the code from Verizon all u have to do is make $75 in payments and they'll unlock it but I tried it with at&t and T-Mobile and with at&t u don't get the same options as u do with T-Mobile so if it was gonna work T-Mobile would be the best bet to try

I notice that you have advanced 4g lte.
When I tried to get that option through Verizon they told me it was not available on this phone.
Obviously the phone is capable of this feature.
Did you get advanced 4g lte after unlocking it with the code on Verizon or because you are using a T-Mobile sim?

Only when I insert a T-Mobile sim it doesn't even pop up when I insert an at&t sim and if u remove the battery while it's on the charger and insert any other sim it automatically greys out

Okay, so the phone has the capability but only through T-Mobile it seems.
Verizon and AT&T must have some sort of block on their network so the feature can't be used on the xt1609. Why, idk.
Makes no sense to me.
In order to be able to dial out you have to change the CDMA Subscription to NV if not you'll get "sim error or no sim" but the calls are still over 1x. Also for whatever reason different sims make the phone act differently. At&t sims only give u an option for APN, if you use a T-Mobile sim long as you change the network mode from LTE to 3g or 2g you get options to change cmda subscription, APN, advanced 4glte, search for networks etc. My network was always T-Cdma on T-Mobile long as I changed to NV while on at&t no signal pops in at all

I'm gonna try again once my month is up if I'm not mistaken CDMA is programmed in the phone so that could be a reason I'm having trouble but I also thought that if I remove the sim the CDMA portion would still work which is not the case but either way all my calls are routed to Verizon

Have you ever tried the method which worked with the prepaid Verizon Moto E phone https://forum.xda-developers.com/mo...-to-verizon-moto-e-2015-gsm-network-t3098953?
I haven't tried it but I think I read somewhere that it didn't work as a matter of fact it doesn't work
Anyone check to see if other gsm sim cards would work in the Verizon version of the moto e4?
Also will this verizon model work on Jio network (850 band available in this set) in India?
I can confirm it works with AT&T Freedompop GSM SIM after buying a $2 unlock code on ebay. Noted it picks up LTE bands 2,4,5,17. Band 5 is the 850 Mhz frequency.

You may need to change the settings to use T-Mobile/GSM network or something like that. Some people mentioned it in the slickdeals forum:

When I first inserted the cricket sim, it wont allow the voice calls. I switched the preferred network from 4g to 3g, the calls worked. Switched it back to 4g and they still work. Try doing this, it works..
EDIT: Remember, it switches from LTE to 3G when making the calls. I got the unlock code from ebay for $2.09.

Hey thanks ! That worked
so, 100% sure that it works to make calls, data and sms when try unlock code from ebay? is yes, i´ll buy one to try in México
I unlocked mine with a code off eBay. I am currently using it on Cricket(At&t). Everything is working fine..data, calls, texts, MMS. Just had to find the correct APN settings. From my understanding...it should be usable on Sprint/Boost but who would want to.
Hi, anyone know how to dial special numbers like *611 or *264 when your using another sim (from other carrier, nota Verizon) ? Because im trying but always appear +1 simbol before i dial
My friend bought the Verizon prepaid version and isn't able to connect to many WiFi networks, like the airport ones (he tried in a couple different airports and none worked), any ideas how to fix that?
I unlocked my verizon E4 through ebay and checked it works with Jio in Mumbai -
4G was working without setting up the APN - just put the sim
I unlocked mine for $2 on ebay and my at&t sim works. sms does have a slight delay sending at times but lte and calls work.
This might sound like a stupid question, but this could be used with a Verizon post-paid SIM, correct? My son has the HTC 10 and it got dropped in water but he is away at school. He should be able to just run to Target, grab one for $40, and take that nano SIM out of his bad HTC 10 and pop it in the Verizon Pre-paid Moto E4 and that's it, correct? No need to call Verizon or anything?

I believe that is correct from what I've read here.
Supposedly, already activated Verizon post-paid sims are good to go. It's when you try to activate the Verizon prepaid phone that you run into problems because the prepaid IMEI is NOT whitelisted. Of course, 'm only repeating what I've read. I don't use Verizon, so YMMV.

Also not a Verizon user here, but as I understand it, putting postpaid VZW sim in a prepaid device that hasn't been active on a prepaid account will result in a lock being put on your postpaid account. This will necessitate a call to VZW customer service to 'reactivate' the account - no calls messages or data until you make that call (from another line)
This is what I recall from discussion around similar use case in the Moto e 2015 forums. Ymmv.

Hmm... That could be a problem, at least in the short term, but he was able to come up with a Verizon LG G2 and popped his SIM in and it worked. A couple days in rice may help, but I have my doubts.
In the mean time, since Target had these on sale for $39.99, I picked one up (my local store had about a dozen in stock) in case the phone is dead and he decides not to get it repaired under the service agreement by paying the deductible (which is $150 I think). Not going to open it for the time being, but will see what happens as time goes on.
I am a little concerned when you say "will result in a lock being put on your postpaid account", since this account has 3 lines in it and neither of us is the account holder. :/ To you have a link back to that information?
I read that they freeze your account and won't let it work with the prepaid phone (on Slickdeals)

Have you tried contacting the website you used for unlock and asking for support? Perhaps this is a common issue that they know how to resolve easily.
Heres the issue. Sprint is a CDMA network, Family Mobile is Powered by T-Mobile, a GSM network. The odds of a sprint device working with any other carrier that isn't CDMA is next to none. I work at T-Mobile and we run across this issue frequently, sprint devices aren't compatible with our networks because of sprints difference in network hardware.

Ive unlocked the phone and it has a CDMA or a global GSM option so i doubt thats the issue. However it seems my actualy issue was that the person who sold me the phone only reported it stolen or missing once i bought it from him.

Take the device to a sprint store and have them run the IMEI, they can tell you. Having it unlocked doesnt mean its GSM if the hardware doesnt support GSM. I have that issue with sprint phones all the time.

The ls997 is gsm compatible, the only thing it wont do is Voice LTE, this will only work on sprint. Most sprint phones use sim cards now days, so the majority of sprint phone can be unlocked to be used on a gsm carrier.

I am still dealing with Sprint now but i don't think they know what needs to be done.
MY device LG v20 (LS997) did received unlocked code.
I did update PRL, Profile, and UICC unlock button in System update .. and it did all without any error.
However when I insert NON-Sprint SIM CARD, the device can't recognize the SIM CARD.
Also I tried to add APN but the device can't save it. (even I clicked SAVE, the new APN does not show up as an option to select).
I am stuck here so badly now. i have 3 LG v20 and plan to move somewhere but I'd like to use them. arghh.
I fought back with Sprint and got MSL code but.. not sure what I can do with it.
There are so many other people in the sprint community forum who are having the same issue as me).
any help/options are appreciated.
thank you.

Have you tried switching it from factory mode to test ? In the hidde menu, i dont remember were it is, but there is an apk that installs the hidden menu witch will allow you to switch between gsm and cdma mode. And i dont believe you need to sim unlock the v20, i dint have too.
I posted this ? on reddit as well; however, this device is on its last legs so there's not much interest for it. I've gotten some good answers here and there on this website, but a dedicated thread to gather all the good info might be more helpful.
I still use my AT&T H910 as I don't really do much gaming on it. Calling, texting, and YouTube is what I mostly utilize it for. I just heard about the whole VoLTE requirement on specific devices after 2022 for AT&T, and 2021 for T-Mobile.
I spoke to AT&T, and they re-assured that the H910 was going to be one of the devices supported after 2022; however, I've been thinking about changing to T-Mobile (my family has a great plan with them, and I always switch back and forth between carriers based on who gives me the best deal) but I can't seem to get a straight answer from T-Mobile about whether my unlocked H910 will work with them after 2021; some didn't even know about the 2021 specifics of it.
I know AT&T will have to allow devices to be used on their network after 2022 even if they're VoLTE capable already. By the looks of it, T-Mobile won't go to that extreme; however, does anyone know exactly how VoLTE works? Specially in regards to using the AT&T H910 model on T-Mobile? Does my H910 has the required Bands to utilize VoLTE on T-Mobile? Or is it one of those things like "Wi-Fi Calling" where T-Mobile Wi-Fi calling only works with the LG V20 model from T-Mobile, and AT&T Wi-Fi calling only works with the LG V20 model from AT&T?
You need band 12 support which H910 has. Also a rom with IMS services working so no AOSP roms.
Volte works by using IMS processes in the rom to route phone calls over IP. No volte = no phone calls. But the device will still "work".
In theory the ATT software will work, unlock it and borrow someone else's sim. In theory a partial cross flash (just system, no modem/aboot/etc) could work if it doesn't.

I was recommended to use an app called Network Mode Universal on reddit for VoLTE testing purposes, and after inserting a T-Mobile SIM card that I borrowed on my unlocked H910 and using the application, the Voice Network Type tab says "LTE". Which is supposed to be a sign that VoLTE might be working on the H910 using a T-Mobile SIM, but that's all I know; just what people tell me.
Update:
The person who recommended that Network Mode Universal app forgot to mention that you have to actually make a call to know whether the phone supports VoLTE with the SIM card in use. When actually making a call, the Voice Network Type tab changes from "LTE" to "UMTS". Which means the H910 is not VoLTE capable on T-Mobile.

Could also be how his sim is set up. Volte has to be enabled there and in the phone. My suggestion would be to force LTE only on the device as well. Does it use VOLTE on his phone?
Also look at IMS registration in the phone and see if it's registered.

The person I borrowed the T-Mobile SIM from uses an iPhone on iOS 13. According to him, the option for turning on/off VoLTE from the settings is gone. He used to be able to turn it on and off at will; not anymore after iOS 13. It should be enabled by default on an iPhone though, I don't see why it would be off. It's almost a necessity on an iPhone I would think.
The LG V20 seems to be more limited in that sense, as on my previous Samsung phone I could enable 2G, 4G, LTE, etc, individually to force only one. I don't see any of those settings on my H910. I don't see any IMS info either.
Either way, I doubt T-Mobile would bother servicing my AT&T branded H910 phone in case IMS needed to be registered; in the case that it wasn't already. I've had really bad luck in the past dealing with T-Mobile on phones that are not T-Mobile branded.

IMS has a phone component and a sim component.
you can check status in the service menu of IMS on the H910. Hope it works on my Tmo phone, getting my sim upgraded

It should work if it's a T-Mobile phone. The H918 is 40% more expensive, so it would be great if the H910 worked with T-Mobile; however, it's not looking good.

Eh, kinda. I'm having trouble too. My IMS services aren't connecting. Going to try a few different roms. I'm through an MVNO so still trying to get them to understand ISIM vs USIM.

Gotcha, I hope it works. I was mentioning to @C D which has helped me understand a lot about VoLTE, that I'm starting to give in to the system of using whatever carrier my phone supports, as long as I can keep using my H910. The removable battery & IR blaster era has come to an end, and I don't think I need another phone right now other than the V20. I might even consider going back to the AT&T MVNO I was using before.

Latest result: oreo works but not nougat.
IMS never registers. Maybe I can fix it. At least now OK sim-wise. Unfortunately doing the sim swap broke tethering.
Hi guys, I am sorry for reviving the old thread.
I too owned H990DS Sea version on latest nougat. It has volte option but just couldn't switch on.
Please take a look at this thread on LG G8
https://forum.xda-developers.com/t/...ther-qualcomm-powered-lg-devices-too.4343655/
I tried on my H990DS using the above thread's method and it didn't work. I was informed that the mbn files are for LG G8. We need mbn files that are specific for LG V20. I have searched up and down and I couldn't find any.
So I hope that I have provided some insights and I hope any member/master/guru out there can help where to find the mbn file (collection of all international carriers mbn) and make volte works for H990DS.
