I got a us996. I popped in my sim card, added an APN, and changed my imei. I got data but no mms or calls. I've searched around a bit but I couldn't find much. If anyone has a work around or knows a solution let me know.
Appreciate it
I would be surprised to see a US996 work on the Sprint network (I happen to own both LS997 ZV7 and US996 USA models). It is known to work on Verizon, but I've never heard of anyone using it on Sprint.
First, the phone's IMEI would have to be whitelisted by Sprint. You can use various Sprint IMEI checkers to verify - Ting's BYOD checker works well for this: If the IMEI is clean, then it will tell you the phone will work on their CDMA network.
And don't you need to do a specific activation process for all phones on Sprint? Just transferring a SIM card between phones is not enough.
Also, I don't think any of the US996 variants have all of Sprint's LTE bands (they seem to lack bands 26 and 41), so even if you get it to work, your LTE signal coverage won't be very good.

I just changed the IMEI to my sprint model to get the Sim card to work. I can get data but can't send MMS or make calls (besides it saying it's forwarding me to a Sprint operator). So I know I can make calls, it's just not setup right.
That's where I think the activation features of a Sprint-branded phone (hands-free activation, profile update, PRL update) come in. Without those or some magic action of a Sprint employee, you're probably out of luck. Unfortunately, there is no LS997 KDZ firmware out there; otherwise, you may have been brave enough to try to cross-flash that onto your US996.

I have a SGH-I337 (AT&T) that I'm trying to get to work with a Verizon sim. I followed the steps in the post below.
http://forum.xda-developers.com/gal...aranteed-free-sim-unlock-mk2-nb1-nc1-t2852979
I follow the steps as stated but at the end the phone has no signal/loses signal using Verizon sim's.
Usually after a fresh boot, the phone will have bars but no data and cannot make calls. The phone states EMERGENCY CALLS ONLY at this point. After a few minutes the service bars will disappear and be replaced with a NO SERVICE indicator.
The phone no longer indicates an invalid sim, but does not auto load APN settings. Manually inputting the Verizon APN settings does not fix it either.
I have checked and it does NOT show the NULL IMEI on the *#06#. Also with the Verizon sim the hidden menus don't always function (*#0011# and such) although I've read that is an AT&T only thing, I'm not sure if that true.
When I insert an AT&T Sim it gets service/data immediately upon booting. I've also tried two different Verizon sim cards.
Thoughts or Suggestions? What am I missing?

I don't own any Verizon phones myself, so I could be totally wrong but:
- Verizon's SIM cards are just for data.
- Verizon uses CDMA (Your subscriber identity is in the ESN/IMEI)
- AT&T uses GSM (Your subscriber identity is in the SIM)
Both networks require you to authenticate yourself with your subscriber identity before they will give you data access.
Sounds like Verizon doesn't have your IMEI, so the phone fails to authenticate/connect.
Try calling Verizon, tell them you got a new phone, and you would like to tell them the IMEI of the new one, so that it can connect to data services.
Either that or they need the number off the Verizon SIM

It should be able to work with CDMA. I've seen the option in some of the menu's I've been through. And the guides have all said that they can work between AT&T and Verizon/T-Mobile or vice versa.
Also, AT&T will unlock the phone for you if you go to their website and fill out the stuff. The only reason I didn't do this is because I'm still under contract and I would have to break that and pay the early termination fee.
I have a SM-935 U device and have been using on the AT&T network. I recently switched to Verizon MVNO (US Mobile). The phone doesn't get registered on the Verizon network. I bought the unlocked S7 edge from best buy thinking that it will work on all carriers. Any help will be appreciated.
The SM-935U do work on all carriers. I have a SM-935V with U firmware on it. I'm with a Verizon MVNO named Total Wireless. Sounds like the phone you go from Best Buy is stilled registered under AT&T...
Not getting registered to Verizon network
When I check the IMEI of my phone against the Verizon compatibility check using their web site, it is fully compatible. The issue is that phone is not getting registered to the Verizon network. I think Verizon is blocking it some how and the MVNO is not able to help me to resolve this.
You ever figure out a solution out to this?

The LTE should work fine, but youll have to set the APN correctly, otherwise it wont get any data, for the CDMA portion youll have to submit the ESN to Verizon to add your ESN IMEI to their database.
Unlocked my Sprint LG v20 through a website someone on here recommended for me (lg simunlock) and used the Network Unlock app and it i used the code to unlock it they gave me and it said successful. even now when i open the app it sais my device has been permanently unlocked.

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.

Then you need to manually setup the APN settings for the data.

Spring LG v20 - Unlock does not work. (even Sprint said it is unlocked).
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 have a LG V20 (model VS995) that was previously from Verizon. I switched to google Fi and my phone has never worked correctly. After months of delaying doing a full data reset as per their suggestion, I finally did it and rebuilt all of my apps but now when I go through the Google Fi activation process, it says the SIM card can not be read. I even ordered a second card just in case but I get the same error. I have tried multiple times. According to Fi support, they are saying my VS995 was never fully SIM unlocked from Verizon. Before I left Verizon, they told me their phones aren't really locked so there was nothing to do. Can anyone verify that I really don't need to unlock my phone? I have been having issues for months and now my phone has zero phone functionality. It can't send or receive calls at all. I will gladly go to a local Verizon store if needs to be SIM unlocked. I am hoping one of you has an answer as googling "VS995 unlock" beings up countless web sites with zero valuable information that actually works.
FWIW, my phone is not hacked at all.
All VS995 models come SIM-unlocked out of the box because Verizon at that time was required by law to do so (they started SIM-locking their phones again around June 2019), so there is nothing needed to do on Verizon's end to unlock the phone, and I'm not sure why the SIM card can't be read unless Google Fi gave you a Sprint SIM card, which is totally different and only works on the LS997 model. As far as I know, Google Fi's main networks are T-Mobile and Sprint. The VS995 is rather bad in reception for Fi since it has none of Sprint's LTE bands and only has LTE bands 2 and 4 for T-Mobile (lacking bands 12, 66, and 71).
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.
