[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,
John

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.

[Q] ZE551ML at&t APN settings

I am not getting 4G LTE. It is staying on H (hspa). I have the one plus one and get LTE.
The info online says this phone should have all of the bands required.
Any ideas.
Thank you
This is the 4gb ram 64gb ROM version

Check Settings - Mobile Network settings - Preferred Network Type and set it to LTE if you have this option and is not already set.
But I doubt that this is your problem. You bought the Taiwanese phone, didn't you? While OnePlus supports all ATT LTE bands (17, 4, 2), the Taiwanese Zenfone 2 doesn't support band 17 (nor ww model), which is otherwise typical for less inhabited aeries in the USA, but it seems that is widely used by ATT. Try the phone in the downtown or another city and you'll probably catch the LTE on other frequencies.

Yes I purchased it from Taiwan but all of the sites show so many bands for this phone. Asus does a terrible job with their model numbers. There are so many different versions with the same model number. There is a 4 g setting not lte and that is selected. I did pick up 4g while driving through part of the city.
Is there going to be a US model?
Thank you

Yes. There is a US model and its supposed to be released in the next month or so. The link below, click on specs, shows the LTE bands for each region. Clearly shows the Taiwanese model not having the 17 band.

That stinks. I took that page as it will work in all of these markets. Oh well
Thanks

Where in US are you?

There are some areas in the US that are only on LTE band 17. I suspect that's OP's issue.

I looked at it and TW, WW and US all have 1700 bands if that's what you are referring to. If not can you shed some light?

The topic is about bands not frequencies. There is nothing such as 1700 LTE band. Actually both USA and TW phones work on approximate LTE 700 MHz but bands are different because uplink and downlink are different. So TW model works on band 28 and US one on 17.

I see now. Tnx for the quick response. Hopefully I'm not outta luck when the phone arrives tomorrow from TW. Do you think that flashing later on a radio or baseband will solve this issue?

It's not that simple. Luckily Intel chip supports all LTE bands. But they must be activated in kernel too. Maybe someone will find the method to activate the missed ones. Otherwise you are not so bad. With TW phone you are short of only one LTE band of four major in the USA, Europeans missed 2 of 3.

Thanks again for that. I see a bright future for this. Appreciate all this info. And definitely will see u around.

CT and work in long island NY. I hit 4g LTE on my way to work but most of the time have hsta+ which is not terrible.

I'm stuck with NO data on my Zenfone 2 with T-Mobile.

Check your APN settings.
Should be
fast.t-mobile.com
make sure the dash is in there.

Thanks that worked. I've always used fast.tmobile.com for my connection and never had issues until today. Now I'm happy and on 4g.

Frequency wise is matches everything AT&T needs, i just picked up my 4g/64gb TW model, i'll be playing with apn's to see if i can get lte to pop. Only getting H+ so far.
Correction, shipped with WW firmware, no 700mhz for us.

More - As posted above, this Taiwanese version is missing the LTE band 17. And there are some areas that this may be the only band available, so you will not have LTE in those situations.

Thanks so much.... I was having a heck of time here with my Zenfone 2 in Tucson AZ on T-mobile.... I was stuck on 2G... but updating the APN to fast.t-mobile.com and 2 reboots seems to have done the trick. So glad I don't have to EBAY this! THANKS AGAIN.... Loving this thing so far!

Well ****! This is where I am stuck win H+ on ATT.
No way around this huh unless someone does a new rom? Or is it hardwired?

is there a way to add 4g lte bands to my note 4 N910P ???

hi all,
I am wondering if there's any way to add 4G Lte bands, I am living in Mex, near el Paso Tx. but as far as I know this phone is not capable to support 4g.

I mean for example open LTE band 3. I know that device is capable to receive network on that band and it is blocked by the operator.

In guessing idoneapps is what y you want, or would be able to help

Thanks. Yeah I saw this thread, but wondered with the S6 using Exynos processor instead of a Qualcomm processor if it stil could work.

I can't advise you on that. I would reach out to the Original Poster on that thread and ask.

I would pay if someone could open LTE band 3.
As i read there is DIY option only for Qualcomm processors.

There is for Qualcomm but not Samsung processors because there is no source for them. Without that, we just can't do it. Your better of just buying an S6 with band 3 or and international one.

If there is no other way, I will stick with 3G - gives almost 10mb

Did you get any success regarding adding LTE bands?

Any chance to have LTE band 20 on this phone ?

Hi guys,
I came across this thread https://zukfans.eu/community/threads/how-to-enable-lte-band-20.427/page-2
Is there any chance to get the LTE band 20 working on this phone. And if someone tried, please share your progress and results
