Canadian LG G4 (LG -H812) - G4 Q&A, Help & Troubleshooting

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:
https://www.frequencycheck.com/compatibility/OXPKu24/lg-g4-h812-lte-a-lg-p1/canada
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.

[Q] SGH-I747M - Unlocking and changing carrier networks

Hello guys! I'm using the I747M variant which I bought from Rogers about 8 months ago and I want to know if I can switch to other carriers network here in Canada via unlocking because Rogers' available phone plans are just a pain in the ass so I want to switch networks. So please kindly share any information regarding unlocking and changing carrier networks. Thanks in advance

Once unlocked, It is guaranteed to work with Bell and Telus.
Hope this helps :good:
Search for it, it's around here in the forums for free. You just need a simcard from the next provider you wish to go to.

How about on other networks such as Mobilicity? My mom is on a plan on Mobilicity and I also want the same plan because my phone is kinda useless without internet and not even a caller ID.
once unlocked it'd most likely work
but for the data part, i can't really say because different mhz on different carrier network..
so 70% chance that you will only get Edge in your area
Does anyone knows any information on how to change radio frequencies on a phone? I've seen some SG3 on ebay.ca that is labelled as "Pentaband" and could work with any carrier network here in Canada. Can someone please explain to me how does this work? And is it possible for my phone to be converted into a "Pentaband" phone?
Mobilicity does not use the same bands as Rogers, Bell or Telus for its HSPA/HSPA+ service. As Pcshano said, your phone would work on Mobilicity, but only on Edge.
You encounter the same problem as T-Mobile users in the US, and WIND and Videotron in Canada. See [WIP][BOUNTY] Enable 3G on 1700MHz for ATT Galaxy S3 i747 on efforts to enable HSPA on 1700MHz on the i747.

[Q] LG G3 D855 SEA V20c no LTE rogers network

Hello, I have a LG G3 D855 SEA V20c running 5.0. I'm looking for permanent fix for LTE. I'm located in Montreal, Canada running on the Rogers network. I recently rooted the phone . I'm looking for suggestions on how to best achieve this.
I have tried the 3845#*855# method but it has to be redone whenever the phone restarts also you get limited 4G coverage with this phone variant
Thanks,

Im just trying to help and apologize if you have already done this but i believe Rogers uses a slightly different apn setting for lte. I havent been with the carrier for over a year now so make sure you got the right settings! If it isnt that then im guessing you are referring to the difference in cellular bands. I do know that USA carriers use a different lte band than us canadians and that for the note 3 devices there was a way to unlock the qualcom chip to enable it but i have not seen such things for the g3 as of yet. Hope i helped:good:

Please check the signals that the 4G band for Rodgers runs on
Sometimes the D855 international variant does not include the signal band that LTE runs on

So do you get lte sometimes? If so it may just be Rogers garbage lte coverage.

My note 2 get's excellent LTE coverage. I think I will flash it with the stock HK rom, I think I will have better LTE control and hopefully better coverage.

AT&T LTE

I have the North American 64gb Zenfone 2. I use AT&T's Share plan and I registered my phone in AT&T's system and it refuses to give me LTE. AT&T claims LTE is enabled on my sim but it doesn't work. When I pop in my brother's sim from an AT&T locked device I get LTE. I do not have any other AT&T locked devices in my house as I recently switched. Can anyone help please??
I am having the same kind of situation with Cricket which is owned by AT&T. My SIM had LTE with my LG Optimus G Pro but only 4G with my ZF2. It is the exact same SIM.
Im on straightalk i used a att sim with no issues on my NA asus zenfone 2, had perfect 4G(lte) signal on 06610.

If the indicater says "4g" that is LTE
OK, cool. My OGP showed LTE when it had the signal. I guess I was expecting the ZF2 to show the same.

Visit your nearest AT&T store and get the rep to delete your ZF2's IMEI from their system. If they won't allow you to, borrow someone else's phone and **get another SIM card** from them. Modifying your APN settings won't help at this point.

I think the phone only shows 4g.. My Nexus 4 (wth LTE Radio) shows LTE..
I am also using Cricket and my phone shows 4G symbol, with speedtest.net I get the 8Mbps down (Cricket caps 4g at that).
When I popped in my t-mobile sim (from the Nexus 4) it also showed 4G symbol, but i would get 26-34Mbps down (which is the 4G/LTE speed)

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.

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.
