Hello, I am looking for some help regarding 4G support on the Mi4. The FDD LTE version of Mi4 is listed as supporting the following:
4G: FDD-LTE : BAND1/BAND3(2100/1800MHz)
TDD-LTE : BAND41 2496-2690MHz
2G: GSM 850/900/1800/1900MHz
3G: WCDMA 850 / 900 / 1900 / 2100MHz
I have seen posts about the WCDMA version, but does anyone know what chip the LTE Mi4 has?
Does the fact that it supports some FDD LTE bands mean software can be used to unlocked it for other FDD LTE bands, such as 800 and 2600?
Does the fact that it covers the 2600 band under TDD LTE mean software can be used to unlock FDD LTE on that band?
Greetings,
I purchased Honor 6 H60-L04 in India during December 2015 in India.It is working fine did not find any issues.Last Week moved to US started using the same mobile in US with lycamobile.As per my plan i should get 4G data connection but i am getting only 2G connection.But in India i was getting 4G connection.Spoke to the lycamobile support team they are not able to help me.If anyone can assist it will be great help.
Honor 6 supports:
Name
B1 (2100) LTE
B3 (1800 +) LTE
B7 (2600) LTE
B20 (800 DD) LTE
B38 (TD 2600) LTE
Lycamobile LTE bands:
Name
B2 (1900 PCS)
B4 (1700/2100 AWS 1)
B12 (700 ac)
The LTE frequency bands used in the US by the top 10 carriers are as follows:
LTE band 2 (1900 MHz) - T-Mobile, Metro PCS
LTE band 4 (1700/2100 MHz) - T-Mobile (primary), Metro PCS, Verizon (urban areas)
LTE band 5 (850 MHz) - US Cellular
LTE band 12 (700 MHz) - T-Mobile, Metro PCS, US Cellular
LTE band 13 (750 MHz) - Verizon (primary)
LTE band 17 (700 MHz) - AT&T
LTE band 25 (1900 MHz) - Sprint (primary)
LTE band 26 (800 MHz) - Sprint
LTE band 41 (2500 MHz) - Sprint
So unfortunately you will not get 4g LTE in the US on a Honor 6 H60-L04, whichever carrier you choose.

Unfortunately no, since the frequency bands are a hardware component and there is no way to make a phone work on a different band than it was originally built for.
If it was software related there could be workarounds, but not in your case. Best you can do is maybe swap your phone with someone going back to India!
I’ve been looking into buying an S8 and the fact that each carrier has its own Galaxy S8 variant made me do some research to make sure I pick the correct phone variant.
I wanted to share this with you guys to hopefully have an aggregated listed to help make someone’s life easier when it comes to deciding: is this frequency supported by this model of S8 or will I purchase the phone and end up on certain bands or frequencies only!
Note: The source of this information is Samsung corporate websites only. No third party website was used. And all credits go to Samsung for properly listing their specs. I just aggregated them in one place to be able to compare them.
Please note the US/North American carrier unlocked model will be released later in May.

Thanks for sharing... and it's neat to compared..
i was looking to buy a International version for tmobile, and most of the comments across multiple forums are B12 support is not there for Tmobile..
but the specs says it supported all of Tmobile bands, should anyone has good experience on this..
the specs mentioned is almost matched with most of the sites i referred, hopefully exynos version support tmobile bands..
Commodore Thanks for the info especially the important reference I've been scouring the internet trying to find the one that fits my needs. Any way is there any frequencies for the US unlocked version? Thanks

US unlocked or carrier free version has model number SM-G950UZKAXAA.
It's listed on bestbuy's site but the network specs don't look reliable, for example the lte bands and the lte frequencies don't match up. I will wait until this phone model gets listed on Samsung's support website and go with those specs. They might drag it out until the end of the month to sell as many carrier S8's as possible. Carrier free is probably not on top of their priority list. But since it's on top of my list, I will wait until the end of May and not limit myself to one carrier specially since this phone is so expensive. (And so cute too ...)

It's from a new MVNO using Verizon's network, hasn't launched to subscribers. Probably why you can't find it and why I am having problems getting premium care from samsung too. Lol

Ok thanks for the update . So the new mvno probably hasn't even started listing the phone on their site. Something like Credo Mobile perhaps.

Samsung's website for the SM-G950U: https://www.samsung.com/us/mobile/phones/galaxy-s/galaxy-s8-64gb--unlocked--sm-g950uzkaxaa
The webpage lists the FDD LTE bands in the specs, but it does not list any TDD LTE band at all!
I bought an SM-G950U from best buy a few days ago, but given the issue of reliability of specs that you mention, I want to find out (before the return deadline) if the TDD LTE bands listed in the first post are really supported on the SM-G950U.
So, how can I reliably confirm that the SM-G950U supports the TDD LTE bands B38(2600), B39(1900), B40(2300), and B41(2500)?
Solved, using dial code *#2263#
Danny Noman found the solution: Dial code *#2263# lists all active LTE bands on the phone, and on my SM-G950U1 galaxy S8, it shows TDD LTE bands 38, 39, 40, and 41.

1. I will be living in the US and Colombia in an orphanage. I am currently in the US and my latest phone is a Note 3 and Verizon (CDMA). Colombia doesn't have CDMA. My Verizon Note 3 will work there, but not well. The closest spectrum match from a US carrier AT&T and I like anything in the Note series. I would like the Note 4 because it has a replaceable battery, a back that comes off so I can add a dual SIM adapter, the price, and if it comes up missing, it won't cost much to replace. However, Claro and Movistar are the two most popular networks in the country, and it appears that I see that the Note 4 and Note 5 do not support Movistar's UMTS B4, so it appears that the Note 8 is the only option if I want to support both. I've never been a band expert, so I organized the information below for your comment. The red in the Note 5 and Note 8 show the differences between them and the Note 4.

2. Another entirely different subject is how good the AT&T network is these days? (Southwest Michigan mostly with some rural.) On Verizon pre-paid I'm always connected and get 13.9 down and 9.23 up in the worst part of the day on 3 bars. How well does it do inside buildings as I'm often buried in basements and wire closets with my IT work. Any advice appreciated.
Thanks TONS!!!

1. I will be living in the US and Colombia in an orphanage. I am currently in the US and my latest phone is a Note 3 and Verizon (CDMA). Colombia doesn't have CDMA. My Verizon Note 3 will work there, but not well. The closest spectrum match from a US carrier AT&T and I like anything in the Note series. I would like the Note 4 because it has a replaceable battery, a back that comes off so I can add a dual SIM adapter, the price, and if it comes up missing, it won't cost much to replace. However, Claro and Movistar are the two most popular networks in the country, and it appears that I see that the Note 4 and Note 5 do not support Movistar's UMTS B4, so it appears that the Note 8 is the only option if I want to support both. I've never been a band expert, so I organized the information below for your comment. The red in the Note 5 and Note 8 show the differences between them and the Note 4.

Get an unlocked international model(GSM), then you can use it anywhere, it just requires changing SIM and maybe flashing the firmware from whatever region/carrier you use the device in.

I run across story after story like this https://forums.att.com/t5/Samsung-D...ote4-LTE-on-the-AT-amp-T-network/td-p/4731477 while hawking online forums of the issues people run into attempting just that. In the case of the AT&T phones all use the 32-bit Snapdragon processor and chipset. The international versions that also have the required bands, use the 64-bit Exynos processor and chipset, which would be incompatible with AT&T's firmware. (Qualcomm chip's modem/radio is compatible with many frequencies but only 6 can be enabled at any one time.) Additionally, in approximately 50% of the instances where users buy even seemingly identical phones from Samsung, or from another US GSM carrier that is not an MVNO of the same network, they fail to get the firmware of the new carrier to flash to their phone, and end up swapping phones to one from the new carrier. It seems at very minimum they run into unresolvable VoLTE issues, and often even basic 4G connection issues. These problems seem to be a common only when a US carrier is in the mix. Thus, my thought is the only realistic option is to get a phone from a US GSM carrier like AT&T, that has the bands I need, and use SIMs in it from Colombia. The Note 8 is the earliest of the Note series from AT&T that has all of the bands necessary to cover all three wireless networks in Colombia.
The problem with the Note 4 is it has B4 for LTE, but not UMTS, which is the only UMTS band used by the 2nd largest wireless network in Colombia, Movistar, and reportedly the network business people prefer. I checked coverage maps hoping Movistar had LTE and VoLTE almost everywhere and wouldn't need UMTS. That turned out to be not true. They have a lot of 3G-only areas and 2G-only in a few. I checked coverage maps hoping to see that I could just use Claro. That didn't look too promising either. In fact, it looks like one would not want to cut themselves out of any of the the three. So it's either a used Note 8, or an inexpensive new AT&T phone that can cover all of the bands. If I bought a new AT&T phone with the required bands, it wouldn't be near the phone of a used Note 8, and cost more. So it is looking more and more like an AT&T Note 8, which is too bad, because from every other perspective, I'd far rather have the Note 4, even if it was the same price.
Thanks!

You might be able to get the AT&T device of your choice and then flash it with a different modem that has been extracted from a firmware from a different region, flashing just the modem can avoid any incompatibilities between the complete firmware packages, i.e. bootloader, kernel, system differences wouldn't be an issue because those aren't being modified.

I like the idea if I can find one that that uses the same processor and it can be done without tripping KNOX. My thought is I would be safer with Samsung Pay than a real credit card...when they get around to implementing it there. LOL!
Something I wish they would do is implement a method to reset KNOX and return it to an exact factory image.

Flashing a stock modem from a firmware for a device that is the same model but from a different region, won't trip Knox, that I know of. Its a stock file so it should pass all security and signature checks by the bootloader/kernel.
Sent from my LGL84VL using Tapatalk
I believe in order to not trigger KNOX, I would have to flash the entire firmware because the modems and bootloaders require the ROM to be of the same firmware. If I do that, I will have a carrier problem. If I don't do that, I would have a KNOX problem.

No, flashing a modem from a different region's firmware for THE SAME MODEL NUMBER device to use the device on a different carrier/region is a very common thing, bootloader and ROM differences aren't an issue, that I know of. If the model numbers on the devices are the same, you can mix and match the firmwares and their parts, certain things might not work as they should, though, but that's more carrier related than it is hardware/software related.
What you're saying would probably happen if you flashed a modem from A DIFFERENT MODEL NUMBER device.
But, I could be wrong, I'm almost sure that I'm not though. I've seen different modems used many times, even done it myself on a few devices.

Got it! I just went looking for what you suggested. Using FrequencyCheck.com, I learned there isn't a modem combination that works in the Note 4 line, nor Note 5. Grrr!
Claro (think Verizon) and Tigo(think Altel) are no problem with their 3G UMTS on B2. The stickler turns out to be Movistar(think AT&T), Colombia's second largest, and most advanced carrier, because their 3G UMTS is on B4. Movistar has VoLTE everywhere they have LTE, but there is plenty of 3G-only between cities. It isn't a good idea to cut yourself out of any of the three. It would be a stretch to give up Tigo, whose claim to fame is to service pockets the other two don't, and you might end up living. However, Movistar could very easily turn out to be the only one capable of usable data in your area.
I hate so say it, but it looks like there will be an AT&T Note 8 with its not-easily-replaceable-battery in my near future.

I'm not familiar with your region, the carriers in that region or which devices would have what support or not. I was just offering commonly used solutions for switching carrier/region.
Maybe someone else can provide more specific info for your particular scenario.

I'd start digging a little deeper and look at other Samsung model numbers with the exact same hardware, i.e. same CPU and same radio. If you find other models with the same hardware, you might find one out of the bunch that has a modem that you can use. It will be tricky, but, if there are enough devices that match, the better the chances of one of them having a modem that is compatible with your hardware and region/carrier.
It would require some intense and in depth comparison of all the minutia of details at the software level, comparing bootloader and modems to find a firmware that has a modem that is compatible with your bootloader and hardware at the bootloader/kernel/coding level. In some cases, a modem can be made compatible by modifying the bootloader from your firmware thrn flashing the bootloader to allow the modem to flash or by modifying the modem to make it compatible with your stock bootloader(or the modified bootloader) before flashing.
It's tricky, but can be done. And it doesn't cause a Knox issue as long as the files are signed correctly. It's risky, modified bootloaders and modems can hardbrick devices, but if modified correctly, it usually works.
I don't have the knowledge to make those kinds of modifications but others here have done things at that level. Members here use modified stock ROMs, stock kernels, bootloader and modems more than you'd think. In a lot of cases, this is the only kind of modifications that Samsung devices with locked bootloaders have the option to use.
Then again, it would probably be much less hassle to buy a device that you can confirm is viable for what you need.

This is what I've summarized based on what I've learned.
U.S. lay of the land:
- AT&T is the GSM network in the U.S. most likely to be able to service you satisfactorily.
- AT&T as a rule does not work with carrier unlocked U.S. or international phones from a practical standpoint. Even IF you manage to get it to work somewhat with their network, you will have at least these service issues:
1) AT&T will not do carrier aggregation therefore maximum download is around 17mbps and upload is around 6mbps while with an AT&T branded phone download is 82mbps and upload is 44mbps.
2) AT&T will not provision LTE advanced features such as VoLTE, Wi-Fi calling, or advanced messaging.
3) AT&T will not recognize the IMEI in order to push secondary LTE bands which in turn also throttles bandwidth.
- AT&T works grudgingly, with T-Mobile phones. Government edict forced them support B12 as well as their B17 (a subset of B12) to be interoperable with T-Mobile. If you go with the T-Mobile phone to pickup the new B71 600 band, you lose out on the AT&T B17 range of B12, which is well managed by AT&T.
- The U.S. Unlocked Note 9 SM-N960UZBAXAA (128GB) is the best of all worlds. It has the SnapDragon, all of the AT&T bands and T-Mobile bands for the current and foreseeable future, AND all of the Colombian band for the current and foreseeable future, AND all of the CDMA bands for Verizon and Sprint. It is in most cases less expensive than the carrier versions. The problem, as mentioned, is getting it to work well with AT&T. I would guess the same situation exists with other carriers as well, and that it would require legislation, like they did with cable companies, to change that.
Summary:
- I need to pick an AT&T branded phone, and get it unlocked in order to work in the U.S.
- The phone needs to be able to also do the Colombian bands.

Summary
I can come up with other phones that will straddle the fence, and some are quite inexpensive. However, if I want a Note, I can't go less than the Note 8 to do it.
Thanks for all of your help!
tittle says it all
is there differences in band support? Im from brazil
I bought my 5T and flashed it from H2OS to OOS using local upgrade, no problem.
