[Q] Use Unlocked SGH-I747 in Thailand on True Move 4G (2100mhz)? - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

Is there a way to check that the LTE radio on the ATT SGS3 will work with the 2100mhz band LTE in Thailand? I tried an updated SIM at the True Mobile shop this morning and my phone would not register on the LTE network. When selecting "Bearer" in APN settings, picking LTE would disconnect my mobile date - setting it back to 'Unspecified' allowed me back onto HSPA+ but not LTE.
- Is it possible for a carrier to restrict the types of phones that can access their LTE network, or is it as simple as having the correct radio?
- Are there different channels on the 2100mhz LTE spectrum, and is it possible ATT uses a different channel than True is using?
- How can I diagnose my radio connection to determine what could be preventing my access to LTE on the True network?
- What is the difference between LTE 700mhz Class 17 / 2100 and 2100mhz LTE?
ROM - SlimBean 7.2 weekly, stock kernel
MODEM - LK3
True Move Press Release - http://truemoveh.truecorp.co.th/news_events/news/entry/1392?ln=en
True LTE - 2100 mhz band 1
i747 LTE - 700 mhz band 17, 1700/2100 (AWS) MHz
- Is there a way to see if I am connected to their 850mhz 3G or 2100mhz 3G?
Please let me know what further information I can provide to facilitate a solution. Cheers and thank you in advance.
[EDIT] Upon closer inspection, these are loafers... er, rather I educated myself about LTE bands and AWS... a tad confusing, but going off of the Samsung website spects, the SGH-i747 is dual band LTE 4/17... which is incompatible with True's LTE band 1.
This may be the push that puts a SIV in my hands...

Will LTE 1700Mhz work on HSDPA+ 1700MhZ

So I heard LTE is backwards compatible with GSM and HSDPA + My carrier supports AWS band 4. Will this work? Has anyone tried it?
So you're basically asking if the AT&T Optimus G will work with T-mobile's 4G Network, right? The answer is NO. Or at least not by default. That's because, even though the phone has the correct band (1700/2100), you would still need the correct radio to be able to use that specific frequency (again 1700/2100) with your carrier. Much like the AT&T Galaxy Note I717. It supports the 1700 frequency, but in order to have that working band with Tmobile, we had to flash a Tmobile specific baseband/radio from the Galaxy s2, Galaxy S Blaze 4G and/or Tmobile Galaxy Note to be able to use the phone on the 1700 freq. So in this case, Unfortunately, Tmobile won't be releasing the LG Optimus G, so there won't be any radios available to use. But, the LG NExus 4 actually has the exact hardware specs or SOC as the LG Optimus G, so a radio/baseband port might be possible.
I hope this post made sense to you.
So what is the difference than taking a locked phone, unlocking it to another network that shares the same GSM frequency?

Actually the two networks don't share the same GSM freq. Yes the AT&T LG Optimus G does have the AWS 1700 band in the hardware, but it is not enabled by default in the software. In order to enable the AWS 1700 freq, you'll need to use/flash the correct radio that carries the AWS 1700 freq. Like i said in the earlier post, one might be able to possibly port the a radio/baseband from the LG Nexus 4. Since it supports all pentaband frequencies.
So why would they disable it if the carrier uses 1700/2100 for LTE? I'm still not understanding its limitation
The carrier I want to bring it to uses AWS 1700/2100 3.5G.
Are they selling a phone that doesn't work with LTE on there network? Or can the phone only do 1700/2100 in LTE ?

It's not that the 1700/2100 bands are disabled. They are very much enabled but the radio is set to use them for LTE.
So you are saying even though LTE is backward compatible the band installed is software limiting the hardware to only allow LTE 1700/2100?

LTE phones are backwards compatible because they support other bands for HSPA and GSM. For example, a carrier using 1700 MHz for LTE may use 850 and 1900 for HSPA but the 1700 will only work with LTE.

You somewhat got it. It is the same problem with AT&T's HTC ONE X. The phone as the 1700 band for LTE, but when used with Tmo it only picks up 2G using the 1900 GSM. But with Tmo merging with Metro PCS, and partnering with Ericsson and Nokia Siemens Network, the H+ 1900 Spectrum will be available everywhere very soon. I read an article on tmonews.com that it should be done by the end of this year.
maybe the Canadian Telus version would work with T-Mo's AWS
it'll work you'll have to use the modem firmware from the N4 in order to use hspa+

[Q] Using T-Mobile Galaxy Note 2 on AT&T's LTE (Will It Work if I do the Following?)

[Q] Using T-Mobile Galaxy Note 2 on AT&T's LTE (Will It Work if I do the Following?)
Can't you flash an AT&T firmware on a T-Mobile Samsung Galaxy Note 2 handset to get the necessary AT&T LTE Frequencies since the LTE radios on both AT&T's and T-Mobile's Note 2's are the exact same? Or is unlocking the Note 2 via T-Mobile more than enough to take advantage of AT&T's LTE Network?
Tread carefully, I'm currently trying to get my phone out of a rather nasty bootloop/corrupt IMEI situation after trying just that earlier today.
But I did get it to work, even pulled 35 Mbps on a speedtest.
Things went to hell after trying to revert back to the T889V modem. (In case I needed the AWS HSPA, for proof of concept and also warranty purposes).
so our phone's LTE modem is compatible with AT&T LTE bands? sweet.
^^^ Did an LTE status show up when you ran the Speedtest; this was with an AT&T Sim, right? ?

Virgin Mobile Canada LTE SIM (previously confirmed working in an Galaxy S III), and yes the LTE icon showed up immediately, Speedtest says LTE too, and the speeds are way beyond what I had with HSPA in the same location.
Doesn't AT&T's LTE run on different frequencies; so will T-Mobile's Note 2 match with AT&T LTE Frequencies after flashing to AT&T's Firmware?

Tmobile's T889 supports LTE on AWS and 700 (band 17).
AT&T's i317 supports LTE on AWS, 700 (band 17) and also on 850 and 1900 (band 2).
So yes, our phone has the ability to work on SOME of AT&T's LTE network, but not all of it; it will just depend on which frequencies they're using in your area. I believe AWS and 700 are new for AT&T, so they're probably fewer and more between at the moment, whereas their current network is mostly 1900 and 850. Not sure what kind of upgrade they have to do to switch their old HSPA 1900 towers to LTE support.
Silly question, so is a tmobile note 2 capable of handling AT&T's LTE network on the 850 and 1900 bands; is this something controlled by software, or a hardware limitation, I thought the Qualcomm radios on the AT&T variant and tmobile variant were the same.

[Q] Can I use a Korean note 2 in the US?

I recently purchased a galaxy note 2 in Korea and I would like to bring it back and use it in the states with AT&T. I read that 4g would not be compatible with the phone but 3g will work? I plan to use this phone for business and I realized the 1 is not designated as voicemail due to it being a Korean phone. Is there way to add this feature on? Are there any other features that I will not be able to use with AT&T? I realize I won't be able to watch tv on my phone anymore.

I don't want to root it and I prefer to keep it stock. I just need to know if the phone will work with At&t's 3g network. It would also be nice if i could fine a way to check my voicemail.

1900 MHz UMTS/HSPA/HSPA+ 3G/4G
1700 MHz LTE 4G
If that's the international version Note II check and see what frequency's it supports,and compare to AT&T or T-Mobile's. International devices are not carrier locked
If it's a branded phone meaning you got it from your cellar carrier, It could be locked to that provider only.
If your using the unlocked phone, look up the specs on your device and see what it supports, if it matches up to the above frequencies you should be good

Ok so I got these specs for my svh-250k and looks like 3g will be compatible but it also picks up umts 2100 and att LTE frequency uses 2100 for 4g. Am I wrong? Do I need to look at the secondary cellular network?

Should I sell my korean note 2 and purchase one in the states? I really would hate to get rid of my brand new amberbrown 32 gig phone and downgrade to a boring white or pebble blue 16gig phone. Decisions decisions.....
I'm in the same situation did you already go back to the states and try it out?

This thread is nearly 5 months old, and the OP only posted 4 times in this thread....total...
You will likely not get an answer from the OP...
Do a general search for info on the Korean note threads...as we have 4 or 5 that may help you in getting your answer....
Good luck to you....g

Just reading the specs I would go with T-Mobile, Faster HSPA speeds if you decide to keep your amber brown. Only downside is T mobile's coverage isnt as good as AT&T but if you re in a major city it shouldnt be a problem.
Good luck!

[Q] Does Lg G3 (D855) support T-Mobile LTE?

Hi All,
I got LG G3 D855 international version from eBay last week, I'm wondering if I can get LTE, or H+ network on the phone. On "Network Mode I can see "GSM/WCDMA/LTE auto" listed , when I choose it the signal bars on the notification area start looping, after that it switch back to "GSM/WCDMA" option !
I added a new APN for LTE , but still not working on LTE.
According to T-Mobile coverage map , my area is support 4G /LTE network . The phone is rooted , software version: V10b-GLOBAL-COM (For Hong Kong)
I can get 10-12MB download speed on H, I guessing it will be a way faster on H+ , or LTE.
Any idea about how to get LTE to work?
Thank you,
I'm surprised HSPA is even working, you must be in an area where they moved it to 1900 (Band 2). The D855 model doesn't support the AWS band, also known as Band 4 or the 1700 frequency (so says GSM Arena anyway) . This band is where T-Mobile has their primary network deployments these days. That means no HSPA+ (that's only on Band 4, not Band 2), and no LTE at all.
Bottom line is I don't think you want to be using the Euro D855 model on T-Mobile USA network. Not the right tool for the job.
Sent from my LG-V500 using Tapatalk
I think it should still work. Frequencies tmo supports (straight from website):
4G LTE : Band 2 (1900 MHz), Band 4 (1700/2100 MHz), Band 12 (700 MHz)
4G HSPA+: Band 2 (1900 MHz), Band 4 (1700/2100 MHz)
3G HSPA: Band 4 (1700/2100 MHz)
The phone supports 2100MHz and 700MHz, and not 1900 or 1700. I just did a speed test and get 4Mbps reporting it used HSPA+. If that works, I'm not sure why LTE wouldn't unless it *has* to have the 1700 to get LTE.
Edit: here's some info on the 700MHz band http://www.spectrumgateway.com/t-mobile-700a-spectrum. I'll try it when I'm on vacation. I live in NC unfortunately.
Hi, I use LG G3 D855 and looking for solution to get LTE on T-Mobile USA. After some research inside the forum, I decided to try to use CyanogenMod (CM 12.1) on my system.
It works well and now I can enjoy LTE on T-Mobile network, even though not pretty stable yet, but I am good with that since the OS still ongoing development.
You can try to download the OS on Cyanogen official website, and use the latest update available.
In order to confirm if you get LTE signal, beside check on your LTE sign, you can use LTE Discovery apps whenever you lost LTE connection and try to reconnect on an LTE signal.
Oh, forgot to mention, I am located in College Station, TX.
Beware: LTE Band 4 (1700/2100 combo) it's not the same LTE Band 1 (2100 only) that LG G3 D855 supports. Better talk using band numbers not frequencies.

No I want to know, what band Radios Verizon Note 4 has, so that I can plan accordingly.
any help is highly appreciated.
P.S Verizon LTE Phones are Unlocked. I used SGS3 with a Lyca SIM. So I know it works, but I'm looking for LTE Band ranges in Note-4.
Thank You.
