Carrier Issues Unlock Phone. - G3 Q&A, Help & Troubleshooting

Dear Members,
I have a issues with my unlocked LG G3 D855, i got it from a carrier called Orange, and i´m using it in another carrier called Claro, my problem came when i sent it to fix some problem to the original carrier, they made a software upgrade and now my phone doesn't get LTE signal anymore (Just get 4G) and in the stock browser my homepage and SIM Tool Kit belong to the original carrier, even when i made a full restart and re installed a new rom.
Both companies have same phone model and use same band to get LTE in the LG G3.
Thanks

LTE and 4G are the same thing. I have never had "LTE" icon, just "4G", but I have gotten speeds up to 148Mbs through it.
I don't see the problem.

Look in settings, about phone, network, and look at mobile network type to see if you are running LTE or 4g(I think it hdsp+)

My network type is HSPAP, I flashed another stock rom but I I just get H signal, I think my problem is about the rom modification the carrier made to the phone.

[Q] No data on T-Mobile G2

I got this really cheap T-Mobile G2 in the US which worked perfectly alright and brought it to to my own network overseas. I know the handset uses 3G on a totally different band but I believe edge connection should work, right?
Anyway, I unlocked it using the downgrade method. Then I installed CM7. I put my own sim card and it does pick up signal and I am able to make and receive phone calls but there is no EDGE. I already set the APN options correctly.
Any thoughts?
You sure the APN info is correct for your carrier? Ability to make calls, but no data are pretty good indications of wrong APN.
Yes, as long as the phone has the same GSM bands used by your local carrier, and you are unlocked, you should be able to get data via EDGE.
Isn't there a reason the us has G2 and the rest of the world has desire z? Aren't the bands different between the 2?

Just different bands for 3G. Your G2 has the proper GSM (voice and EDGE) to work in most parts of the world.
And the G2 name is just T-Mobile's branding and to signify the vanilla (no Sense) ROM. The Canada, Europe, Asia versions of the Desire Z all have different bands from each other.

Completely sure. Used the same sim I use in my main phone which is also android based. Could it be a radio issue? I was tempted to flash a new one but since Im not that familiar with this particular phone I don't feel like messing up, especially when all I want is the phone to work so I can sell it.
BTW, anyone interested PM me - although I believe I shouldn't post this here.

LG G2X unlocked but no 3G on GSM

Canadian here,
I picked up an LG P999DW Optimus G2X (Optimus 2x) Link and I unlocked it with the Octopus. I have put in a Rogers(GSM) Sim and I cannot get it to work with 3G even after I put in the correct APN settings. Can anyone help me get 3G working please?
Thanks,
Freerider_4life
Bump, can someone please give me a hand with this? 2g is terribly slow
Make sure the phone and sim are cooperating
I'm sorry to hear that you are having issues with getting the right network, but you might wanna check with the phone's hardware, and ask the people who you bought it from. I remember my brother got an iPhone 4S unlocked straight from Apple store, and even though the iPhone 4S supports at least 3G speed, my brother is not getting the 3G speed because he is using a T-Mobile powered SIM, not exactly T-Mobile. At the same time, I use that exact same SIM on my HTC G2 and I get 4G/HSPA+ speed, so it clearly depends on the phone.
The phone itself and the SIM has to cooperate in order for you to get the speed you deserve for that phone.
Hope that helps, I don't know much but I've noticed it a lot.
it all depends on bands, most unlocked devices only get EDGE(or 2g) on other networks it will only get 4g or 3g on the device the carrier it was made for unless the phone was made otherwise

Canadian LG G4 (LG -H812)

Hey Guys, I have a concern with my recently purchased LG G4 model H812. It's originally from Rogers and I got it unlocked and have my Virgin Mobile service working on it. I have put in the right APN Settings according to the specified network and LTE hasn't even shown up at all since I've purchased the phone. Under network mode, I have chosen "GSM/HSPA/LTE" but all i see thats working constantly is 4G. I also did a manual search under 'Network operators" and chose Bell LTE instead of Bell WCDMA. Any ideas of what can be done?
Thanks

WRONG!!! Virgin mobile in Canada is GSM... see this:

UMTS is a form of GSM

You may want to check out this link (https://lg-firmwares.com/lg-h812-firmwares/) for an H81220X Bell/Virgin kdz (H81220x_00_1122.kdz) and use LGUP-NEW to install it.

Sprint G5 Unlocked by Sprint (Domestic & Abroad) will not work with AT&T sim?

Any idea why the G5 I have that was unlocked by Sprint OTA will not work with my AT&T SIM? The phone shows the "Bad SIM" icon and refuses to work. I checked the ##DATA# settings, and LTE + LTE roaming are on? Any ideas? Thanks!
I'm no expert, but I believe the Sprint network and phone antennas are 180 degrees different from AT&T.
- Sprint uses CDMA; AT&T uses GSM/UMTS/HSPA+
- Sprint 3G uses bands 10 and 1; AT&T uses bands 2 and 5
- Sprint 4G uses bands 25, 26, and 41; AT&T uses 2, 4, 12, and 17.
Unlocked or not, a Sprint phone antenna is not designed to connect to the same networks as an AT&T phone.
I know there many more knowledgeable than I here, so I welcome corrections.
Change band priority
4 and 2 are from AT&T
Put 1 and 2
And Select GSM on network preference
Open Dial 5689#*992#
Field test
Módem settings
RAT selection and select
GSM/ WCDMA / LTE Auto
@adop_19 Don't get the field test menu when typing the above code. Get "HiddenMENU' with the following;
Device Test
ELT Test
Factory Reset
Log Service
WVDRM Keybox
Any ideas? This is puzzling as Sprint swears the device has been unlocked OTA? There are others on this forum using the same device on Cricket, and thus I believe it should work on AT&T? I am at a loss? Thanks.

You have u msl code?
Yours may have only gotten internationally unlocked. Sprint has 2 unlocks. They sneakily volunteer information and assume you mean international unlock only. You have to specify domestic unlock to get it to work in the US if you unlock through Sprint's OTA. It does have the bands to support GSM in the US. Even the G4 does. I unlocked one and have it running on T-Mobile. Talk and text only since it didn't give me the APN menu then, but that's ok, it stays near wifi. If you can't get back in touch with Sprint, there are other ways to get it done without them. You'd have to PM me for that part.
Just Reread The Title. It sounds Like they didnt really domestically unlock it.
Is your agreement with sprint for the device fullfilled?

Fyi, being domestic unlocked vs released by sprint are 2 different things

Yes, it only gets Talk, text and 3G and you can only get it working by swapping your SIM. Verizon won't do it if you ask them

There is a free guide to try in dev section
Piggy backing this thread. I've had my LG G5 domestically unlocked by Sprint. I've put in both a ATT and T-mboile sim and added the correct APNs. Calls work so it is definitely unlocked but I can't for the life of me get data to turn on. Not even 3g. Any ideas? Sprint service is deactivated so that shouldn't interfere with the LTE and data. Bands 2,3 ,4, 5, 7 and 12 are enabled according to ##DATA# LTE is enabled. LTE roaming is enabled as well in there.
In network mode I have Automatic, LTE/CDMA, CDMA and GSM/UTMS only. Currently set to automatic. I also tried gsm/utms but nothing.
In LTE discovery I noticed it found LTE band 12 for a second but just connected to UTMS with no data. Everything shows as not roaming (maybe that is the issue?! since these non sprint lte bands are considered roaming bands or something). Reception is good in the area. I usually hit 20mbps+ down in this location with the same sim using band 4.
Help please!
I have a Sprint LG G5 (LS992) and before the ZVC update, I was able to get LTE coverage in my house all the time... Now, after the update disabling my hiddenmenu app trick, I was forced to pay for remote sim unlock for the phone, and everything went great, I have full functionality, and pretty good speeds, using AT&T service now, but I don't get LTE anymore when i'm home... I haven't tried it anywhere else, that is my next move... Just wondering if there was something I missed... I set up the AT&T APN correctly from the ATT website apn settings, have gone through all the hidden menu settings, RAT Selection gsm/wcdma/lte auto, I dunno what I'm missing, other than it just wont work on LTE anymore.

No actual LTE or 4G just 4G Showcase (Icon)

Hi everyone.
I'm using T-Mobile LG G3 D851 right now. I upgraded via OTA method few days ago. I noticed a bug or what I should say I don't know. LG G3 D850 have LTE feature. When I set network mode to AUTO GSM/WCDMA/LTE, it shows 4G when I turn on Mobile Data. I checked the About Phone section and also checked Network State. In network state, I always find Mobile network type showing HSPA or HSPAP. I never found LTE. I contacted my Service Provider. They informed me that you've an LTE SIM card and you have full LTE Signal Strength in your are. Please anyone tell me, why I'm not getting LTE?
At first I got kind of confused. The 4G icon indicates LTE on stock ROMs. HSPA, however, indicates 3G. Here's the deal, the G3 phones are not equal. The D851 is a T-Mobile GSM phone. The D850 is also GSM I believe but for AT&T. They support different bands. Even though the phones and your SIM is LTE capable, that doesn't mean they both work the same on a given network. You're in Pakistan on the Zomg network. The D851 can't take advantage of the services there.
Screenshots below show that the D851 can't do LTE there but the D850 can. It's always best to check the bands a carrier uses and compare them with what a phone supports. GSMArena is a good place to check that.
You might be out of luck with the D851. Not sure.
@iamqaisarkhan, here's a list showing the LTE bands supported between the two phones. D850 supports more bands including the one used by your carrier.
