at&t mobile network options - LG V40 Questions & Answers

Anyone have the lg v40 running on at&t? surprisingly i have no options under mobile networking. I can only enable international data roaming and setup new apn. Usually i'd expect to see settings allowing me to change the bands.

Everything is auto- , the phone I have is locked to att and I guess the only way to change that is to unlock the phone.

It bounces off 2 things, the phone's props and the network being detected. Using the unlocked does not enable settings if it's not natively supported by the carrier contrary to popular belief. That was true on older versions of android. Newer ones relies on multiple configs to decide what options you get to see or not. In most cases, if the phone model is not what is expected for a particular network, it will default to global roaming mode that has the least set of options. From what I've seen, this comes as a result of carriers requesting to have specifically designated models tailored to their service.
If you are rooted, you can tweak stuff in build.prop to have the phone switch carrier and regional modes.

root not needed:
1. for network mode, try dial *#*#4636#*#* and then phone information, this works on my v35 with tmo and att sim, you can also use a 3rd app called "network mode" which is a shortcut of the above, hope that works on v40 too.
2. for band selection, I use 277634#*# on v30(tmo unlocked) for both tmo and att sim; I use 277634#*# on v35 (both att unlock and usa unlock) for tmo sim; I use *#546368#*350# (need to dig into the menu to find band selection) on v35 (both att unlock and usa unlock) for att sim; hope either one of these two works for v40.

No Unlock Menu Pops Up

I bought a US Cellular Moto X off of Ebay. I unlocked the Moto X successfully since I receive the message each time I turn on my phone but no unlock menu popped open.
I have the correct T-Mobile SIM card, I am able to search the internet but I can't make calls, receive calls, and the same for texts. When I call, I receive the welcome to verizon wireless message and the texts do not go through.
Please help.

If you go to the main settings menu, then under Wireless & Networks, select More... and in the new screen that pops up, select Mobile networks, then Access Point Names, you'll have to find the APN settings for your carrier and add them manually if they don't show up when your SIM is inserted.

There is a way to access the APN list using a hidden programming menu. I don't know if the dialer shortcut will work on the version you have, but to try it, dial ##7764726 if it works and asks for a password, use 000000
One of the options should be APN controls. Hopefully T-Mobile US will be one of the APNs.
Is it possible that there might be a problem with your SIM card since some features work and others dont?

I'll try that.
It's US Cellular phone but I use T-Mobile SIM card, it was a brand new sim card. When I dailed, I kept getting "Welcome to Verizon Wireless"
Thanks, I'll let you know how it goes in a few hours.
According to US Cellular's webs site, their device supports CDMA/EVDO, since you are trying to use it on T-Mobile, you'll need to manually switch the phone to GSM/UMTS mode, or Global Mode. (App drawer -> Settings icon -> (under Wireless & Networks) More... -> Mobile Networks -> Network Mode).
While in there under Mobile Networks, you'll also need to tap on Access Point Names... If the APN settings came down automaticlly from T-Mobile you need to select it. If no entry for T-Mobile exists, you'll need to find the settings and create one. (Google found them when I looked) NOTE: with Android JB 4.2.2 on my Verizon X (XT1060, also supports CDMA/EVDO in addition to LTE and GSM), the APN settings came down automatically. After upgrading to KitKat 4.4, I had to manually enter them.
When I setup my Verizon X for use with my T-Mobile SIM, I couldn't get MMS working for some reason, even though I was using the same APN settings as my T-Mobile Galaxy S3.
Also, keep in mind that T-Mobile uses 1700/2100 AWS for their HSPA+. As far as I know, only the T-Mobile version and GSM Developer edition supports this band, so you might not get "4G HSPA/HSPA+" with your X even after setting it up correctly. If you are lucky, and are in one of the areas where T-Mobile has completed re-farming their spectrum, you will get H+.
Good luck.

Based on that screen shot, your preferred network mode is still set to LTE/CDMA... that is wrong for T-Mobile. (SEE POST #12 of this thread!!) You want it to be GSM/UMTS or GLOBAL!! And you want to have the boxes checked for Data Enabled and Data Roaming.
You do not have options for Global Data Roaming Access and Access Point Names which I have on my Verizon Moto X, so that makes me question a few things....
In the first post you say you successfully unlocked your phone.. do you mean SIM Unlocked, or BootLoader Unlocked??
Also in the first post you mention seeing a message each time you reboot.. What exactly does the message say?
I ask because if you unlocked the boot loader, your phone could still be SIM locked and therefore not recognizing the T-Mobile SIM properly, and not giving you the Global options and APN options needed for GSM mode.

It is BootLoader Unlocked not SIM unlocked.
The message I get is about the warning about the bootloader being unlocked.
I believe it is SIM locked still.

Yes, if not SIM unlocked, you're stuck. You need to get it SIM UNLOCKED.
Take a look at this thread -> http://forum.xda-developers.com/showthread.php?t=2422854 apparently some are using cellunlocker [.net] to get their X SIM unlocked, although they don't have US Cellular listed when I picked MOTO X from their list, so you might have to pick "Unknown" or "not listed" for the carrier.

[Q] VZW DE: does boot unlocked imply SIM unlocked ??

I've got a an unlocked rooted VZW DE. I'm going to Europe. Is the phone SIM unlocked ?? Can I just insert a European sim card ?
IOW, does an unlocked bootloader also unlock the sim card ? Or do I have to spend an hour talking to Verizon?
Thanks,
sean
After talking with VZW, they tell me the phone comes SIM inlocked! Interesting if true. I'll find out next week.
sean
Any Verizon LTE phone should automatically be sim unlocked without the bootloader being unlocked due to Block C agreements requiring Verizon to allow any compatible phone to use the network. Since LTE is basically the evolution of GSM, most (I won't say all, because there may be an exception) LTE devices have GSM capabilities. Verizon can't legally sim lock the LTE radios, so they have just stopped sim locking global phones.
tl;dr Yes, it is by default sim unlicked. Just throw in the sim and update apn settings if necessary (they may be preprogrammed). You probably won't have LTE, but HSPA (and, I assume, HSPA+) should work fine.
Edit: I just reread and realized that you had updated the post with what I just said... You can ignore this.
No. I appreciate the background. And really pleased it confirmed what Verizon said.
Is there a list someplace of the APN s for French providers? I can just imagine trying to find it out from the kiosk manager using my French!

I think they may have that information on the provider's website. You may want/need to plan ahead to determine what carriers are there (which you probably know already) and check out their sites, or you can probably Google '[Carrier Name] apn settings' and find it that way. I've never been in a situation to change the apn settings, but I think once you insert the new sim, the setting is available under Settings > Wireless and Networks > More... > Mobile Network Settings > Access Point Names.

LG G4 Sprint SIM / Network unlock

Has anyone been able to SIM / network unlock Sprint variant of LG G4? For international use? for domestic carriers?
The phone appears to be locked. I tried putting GSM micro SIM and putting phone in to GSM mode. Got an icon about invalid SIM in notification tray. But no prompt to unlock. Also no menu in settings to unlock via network like my note 3 had. Even worse, no menu to select GSM Network operator in the settings.

I know , that is the theory, I am curious if anybody actually tried it. I am concerned about the fact that I don't see a menu to select GSM network, which was there in Note 3
it almost looks like the phone can roam on GSM network using Sprint SIM, but all the menus that would allow presence of different SIM where removed.

Friend called Sprint and they unlocked his phone OTA. Now when non-sprint SIM is inserted it no longer complains about invalid SIM, however it will not connect to any networks in USA and still no way to see a list of networks or do a manual selection of network. That menu is still missing. I suspect the phone will now work outside of the USA in automatic network selection mode only, which may not be a good thing some times.

Doesn't matter what you try, you cannot use Sprint's phone on AT&T T-mobile here or any US GSM carriers. When sprint unlocks it for you, then you can use it outside of US on GSM Networks.

You must be new here. Domestic gsm has been unlocked on most modern Sprint smart phones. Just in the years I've been with Sprint ive unlocked the Moto Q, G2, S4, and now the G3 for ATT and straight talk. Ive read of several others having the same ability. The s5 can also be unlocked but only one guy knows how but you gotta pay him for it. Kinda ****ty but it actually works.

You didnt listen... Sprint phone works 100% for att.. They jt blocks it at the software level... But my friends has unlocked all the newer sprint phones till now.. I dont see why he shudnt be able to do it here
Any chances of unlocking when outside US? I got my phone from Amazon and got it shipped in my country. Tried calling them but they said they only unlock activated phones. Also tried various sites that offer unlock codes but since G4 is not asking for unlock code, they can't do anything.
Do I have any other options?
For those still trying to unlock, I've followed this post for unlocking the G3.
http://forum.xda-developers.com/sprint-lg-g3/general/sim-unlocking-ls990-zv8-t3083567
And I can now accept calls, will try it out some other time if I can get data as well.
Note: Make sure you have the correct permissions on the files that you'll copy.

I can't confirm, since I don't have access to any AT&T SIM at the moment. If you're already rooted, you can try it out, but make sure to back up the files.
Another update: After updating the APN, my data finally worked. LTE is impossible at the moment since the this doesn't support the LTE bands here in my country
Warning: Don't try to disable auto activation for now. I got the Security Error and still on the process of fixing it.

Use your Sprint phone on T-Mobile.....ZV6 users only?

This is not mine, I take no credit, Mayrer has done most of the hard work for us, you credit him for his work and everyone he has worked on to get your Sprint to working for GSM.
http://forum.xda-developers.com/spri...nlock-t3229801
I have only updated the information for changing in hidden menu and PropEditor. I also credit the maker for the CDMA to GSM Patch, Mentor.37 for his work and everyone else who has helped him.
http://forum.xda-developers.com/showthread.php?t=2394689
I do not know if this will work for any other Sprint phone not on ZV6
Bands 2, 4, 12 are for bands T-Mobile.
Download PropEditor and edit these settings....Don't forget this step first!!
ro.build.target_operator=SPR => TMO
ro.build.target_country=US
ro.telephony.default_network => 9
telephony.lteOnCdmaDevice => 0 ....don't forget to save and reboot.
Along with Hidden Menu 5689#*991# to change your APN settings properly and set
Field Test => Modem Settings =>
PDP Setting => [5] APN Setting ...... now you have to select the bottom one then go into menu [ ] press until you see delete APN
you must do this because a bug I am seeing only allows the bottom APN setting to be used, I usually delete all until the APN I use is on the very bottom selection. no go back
Network Mode = Automatic => go back => RAT Selection = GSM/WCDMA/LTE auto
LTE Band Selection doesn't work proplerly so installing the modded Shortcut Master (Lite) from the link above be sure to go to
lotHiddenMenuMain (witout root) => LTE setting=> LTE Data Roam Config....and enable
Bar Roam Forced
Bar Roam Enabled
Roam Guard Forced
Roam Guard Enabled
Band 2
Band 4
Band 12 go back
Band 25 should be disabled unless you can use it. You cannot really set APN here.
I sometimes install the CDMA to GSM patch for global phones but I then have to re-do the PropEditor settings again, but it may be able to configure anything else that is missing, you can try to Adb Sideload the zip or use FlashGordon app to try to install, honestly I don't know if either worked for me for the patch.
This is what I configure to get my phone to working with T-Mobile.
I only submit this, I cannot provide support, you can always add on to anything else I may have missed or messed up, thank you.
Has anybody with an LG G4 rom version ZVG been able to successfully get their phone working on T-Mobile?
My phone is paid off and Sprint sent the domestic SIM unlock code. When the TMO sim is in and the phone's network mode is set to Auto, and and APN is manually entered per TMobile's specs, the phone can connect to the network and make calls, send SMS, connect to EDGE data, and sometimes send MMS, but it never connects to LTE. If I change the network mode to LTE/CDMA, the phone doesn't connect at all.
I read elsewhere to try change the "Bearer" field in the APN to "LTE" but that field is not displayed or editable in the APN input/edit screen. I tried a bunch of the Shortcut Master (Lite) or similar ways to expose the hidden menus to edit the full APN but they all fail due to permissions (because of ZVG version?). Shortcut Master (Lite) says it would work if upgraded to the paid Secret Codes version, can anybody verify that before I pay?
Or, any other suggestions to get this fully working with LTE or can even confirm that this is possible?
guys this is kinda old news
the build prop also is better set from
ro.build.target_operator=SPR => OPEN
then xposed modules such as android theme and such work.
but great find on thew band settings
ive been running my g2 g3 and g4 on tmobile and att and its subsidiaries for a long times now
and the g series sprint phones have been the best at taking to other networks due to the sprints already supporting most of the bands`
---------- Post added at 08:43 AM ---------- Previous post was at 08:43 AM ----------
request for modderators to move this thread to the general area
i also thin the mellow mallow international roms go up to zvb which should work on tmobile and i can verify att networks
Doesn't the phone need to be rooted for the build prop to be edited?
And as far as I can tell, there isn't a root for a G4 on ZVG firmware?
Basically, to start with, can anybody confirm if a LS991 ZVG can be made to work on TMobile without root, or if there is a good rooting method, where is it?
Thanks.

Can you be more specific on what I need to ask Sprint about? Like I said, I asked for the the Domestic Sim Unlock and they sent that over the air and a confirmation showed up on the phone. It does not reject the T-Mobile SIM like it would normally, so something has changed from the default state.
Still looking for confirmation from somebody that has successfully connected their ZVG LS991 to TMO after a Domestic Sim Unlock.

T-Mobile Revvlry Plus XT1965-T: About Network Unlocking (please help)

Hello,
I have just acquired a new (never used) T-Mobile Revvlry Plus XT1965-T, and it seems to be network locked. (Note: I was able to get an OEM unlock code from Motorola, haven't tried it yet, but right now I am only asking about the network lock issue.)
My goal is to install LineageOS 18.1, and use this phone with other mobile service providers in Canada.
I want to understand how to deal with the network lock, and get past it -- I have some questions...
1. If I simply follow the official instructions for installing LineageOS, will this result in a network unlocked phone?
2. If just installing LineageOS won't remove the network lock, why is that? How is the network lock implemented on this phone?
3. Is there any way to clear the network lock, without going through T-Mobile?
4. If I must go through T-Mobile and use their unlock app, I assume that I had better do this before I do anything else, and once the phone is network unlocked using T-Mobile's app, then the phone will remain network unlocked after installing LineageOS, is this correct?
5. I get the impression that there are actually two different phones with the same model number XT1965-T, being the T-Mobile version and the Motorola version, is that right? What are the main differences?
Any other comments, insights, or links are also appreciated. Please keep in mind that while I am highly technical, I am not an expert on Android or smartphones.
Thanks.

5. I get the impression that there are actually two different phones with the same model number XT1965-T, being the T-Mobile version and the Motorola version, is that right? What are the main differences?
Any other comments, insights, or links are also appreciated. Please keep in mind that while I am highly technical, I am not an expert on Android or smartphones.
Thanks.

1. No, network lock is related to the carrier. If it's a TMO Revvlry+/Revvlry Plus, then it's locked to T-Mobile. This means it can't be used with another carrier essentially. Network lock again just means if a TMO sim is installed (and it's locked to TMO) it will work. If another carrier sim is installed and it's network locked, the sim won't function.
2. If the phone came from TMO, they would lock it to their system.
3. Removing the network lock allows other carriers to be used. There are pay to use services that will network unlock the device within 24 hours. Manual methods exist, but will require more in-depth knowledge. Otherwise, TMO is the one to network unlock it but could take 30 days and may require service with them.
4. Once unlocked it should remain unlocked, regardless of stock or custom ROM.
5. The TMO Revvlry+ (Revvlry Plus) and Moto G7 Plus are the same devices hardware wise. The main difference is the boot animation and logo branding. The Moto G7 Plus is also carrier unlocked.
How did you determine the phone is network locked?
Is the phone tied to a network carrier already?

Thanks for your reply, here is some background...
I bought several of these phones on eBay, they were advertised as network unlocked Moto G7 Plus phones, but the seller instead shipped me network locked T-Mobile Revvly+ phones.
My first step was to test a SIM chip from a local mobile provider, and the phones show a message saying they are SIM locked.
The phones are clearly new and unused. The seller claims they are open-box returns.
I called T-Mobile, and T-Mobile says these phones are registered to active accounts, and they can only be unlocked if the account holder requests it. T-Mobile reps also say they are unable to identify the account holder, and offer no solution. The phones are not blacklisted or reported stolen. If I had to guess: most likely, the phones were purchased, activated, and returned to the store, but the T-Mobile account registration was not cleared in their database.
It seems that these phones use an unlock app, rather than an unlock code, and from what I've read, it may not be possible for any third-party unlocking service to unlock these particular phones.
Getting back to my questions in my original post:
- How is the network lock implemented on this phone? (I mean this question from a technical perspective)
- Is there any way to clear the network lock, without going through T-Mobile?
The network lock must be a setting somewhere in the firmware... I've heard people talk about flashing the baseband, but not being a phone expert, I don't know much about that, or if it might apply here...
So again, I am asking: is there some way to network unlock these phones, and make them usable with another service provider? Can I somehow just reflash whatever area in the phone holds the network lock setting with stock code that doesn't have the network lock setting enabled?
Thanks.

If they are registered and active, they may have to wait out the time period from T-Mobile to be Network SIM unlocked, depending on when they were originally purchased by the original owner.
If they were returned to the store, how did the eBay seller obtain them?

If an unlock app is needed, this may be built into the phones firmware that only T-Mobile can use. It may still require a code to be passed to the unlock app.

It's implemented by T-Mobile. T-Mobile is going to be your best shot. You may have to make multiple calls to get through to someone where you can explain the situation and see if they will network unlock the phone.

Baseband typically indicates the frequencies the phone can use to communicate with different networks. If you take a nandroid of the phone, you can always try to flash a new baseband and test. If it doesn't work, restore back.

You can try to flash the T-Mobile Revvlry+ into a Moto G7 Plus: https://forum.xda-developers.com/t/revvlry-to-moto-g7-plus-conversion-guide.4136355/ That would get rid of the T-Mobile software. It's not clear if that would remove the network SIM lock, but if you take a nandroid backup, you can always revert back.
EDIT: I was doing some additional research, and flashing the modems/baseband or converting the TMO Revvlry+ to Moto G7 Plus won't affect the network SIM lock. The app is in the TMO software and you'll have to use that app with the code either TMO provides or an unlock service gives to network SIM unlock the device.
EDIT2: After booting into the phone, do you have the options in the following settings: SIM unlock phone. This link is only for info and reference: use any network provider’s SIM card in T-Mobile REVVLRY+
Hi, thank you again for your reply.

As mentioned, the phones are clearly brand new and never used.
I would also like to know how the seller obtained them, unfortunately the seller is non-cooperative.
T-Mobile is also curious about how the seller obtained them.

I may try this again, but I have already spent hours talking to T-Mobile Technical Support with no progress made.

I am still not clear as to why the phones can not be unlocked by replacing certain firmware/software. The lock is a setting somewhere on the phone, why can this setting not just be manually changed/cleared?

When I go to the menu: "Settings > Network & Internet > Mobile network", all further options are grayed out.
As such, I am not able to reach the option: "Settings > Network & Internet > Mobile network > Advanced > Network Unlock > Permanent Unlock" as shown at the link you provided.
(For reference: https://www.t-mobile.com/support/de...revvlry/mobile-device-unlock-t-mobile-revvlry)
Any further suggestions/advice much appreciated, I would really like to be able to make use of these phones.

The app is provided via TMobile. This is not provided via software/firmware except by TMO.
Your best bet at this point is to try a pay to unlock service that will provide instructions on unlocking the SIM, if TMO is unwilling to do it.
(Modems change the baseband used by different providers so changing/updating it via firmware isn't going to unlock the SIM/Network. If you get the SIM/Network unlocked and THEN have an issue with a network carrier, flashing the correct modem for that provider would allow the SIM/Network to communicate.)

Do have service with TMO? If not, you might try getting a SIM/Network card from them and inserting it to see if the in-phone options appear so you can unlock it. You might also try escalating the issue with TMO if you are only getting to first line technical support personnel.
The phone is obviously locked to TMO as it's a TMO phone. It's different than the Moto G7 Plus which is already unlocked for all carriers. If you can't get the phone Network/SIM unlocked, maybe return it to the eBay seller and look for the Moto G7 Plus which will give you less headaches.
