Hello,
Not sure if this possible but my Note 4 sadly isnt receiving LTE at the moment. AT&T requires 700 mhz for LTE in my area and my phone does have 700mhz, but on band 28 in stead of band 17. IS it possible to flash my phone to use band 17 instead of band 28? Any help is appreciated.
They are different bands so it won't work...
Hello,
I'm trying to make sense of the LTE frequencies, so maybe you can help.
The situation: I'd like to buy the phone and use it on AT&T LTE in the US, but -- very important -- also use it for data when traveling outside the US. Also, I'd like the ability switch providers in the US (that's why I'm not buying a subsidized phone from AT&T).
The question: The Note 4 model SM-N910W8 has more LTE frequencies than the model SM-N910A. I assume it means that the SM-N910W8 is more likely to perform well in foreign countries and on other US carriers. If so, that's a better purchase than AT&T model of the phone (SM-N910A). Is this correct?
The data:
According to GSM Arena, the "North American" model SM-N910W8 supports
LTE 700 / 850 / 900 / 1700 / 1800 / 1900 / 2100 / 2600 (Bands 1, 2, 3, 4, 5, 7, 8, 12, 17)
According to Samsung website, the specialized AT&T version of the phone SM-N910A supports
2G GSM : 850/900/1800/1900;
3G WCDMA : Band I/Band II/Band V;
4G (LTE Cat 4 150/50Mbps) : B2 / B4 / B5 / B12 / B17
(the system won't allow me to provide links to the data sources, but PM me if you'd like them)
I was also confused about all the band stuff. I am on AT&T myself and I just purchased a note 4 sm-n910c. it is the exynos version (some people don't want that) but it supposedly works great with AT&T lte. The phone arrives on Wednesday soo I personally don't know. But I did alot of research before purchasing.
My current att branded note edge (i assume same as note 4) supports
4G FDD LTE: B1(2100), B2(1900), B3(1800), B4(AWS), B5(850), B7(2600), B17(700), B20(800);
And the 910c supports:
LTE 800 / 700 / 850 / 900 / 1700 / 1800 / 1900 / 2100 / 2600
(Bands 1, 2, 3, 4, 5, 7, 8, 17, 20)
You may also want to look into the sm-n910u
Thanks! So according to the source below, a "band" is simply a range of radio frequencies. That's why there's an overlap between "radio frequencies" and "LTE bands".

My impression is that the more frequencies a device has, the better it performs across carriers, when roaming. And of course, any carrier is better off selling a device that's customized to its own network, thereby making switching carriers more difficult. I guess that this is why the AT&T model has fewer frequencies than the non-AT&T model.
By the way, the seller of the SM-N910W8 assured me that the device is capable of the same LTE speeds at a SM-N910A.
Right every carrier uses specific bands of frequency. Some work on multiple carries. For instance the t-mobile note 4 work on ATT network.
I don't know much about the 910w8 but yes the more bands it supports the more universal it will be across carriers. Of course GSM phones will not work on CDMA networks like version and sprint

That's right. And my hunch is that carriers limit their branded phones (the subsidized phones they sell). This way, the phone will perform best only on their network. At least in the case of AT&T, I can't find another explantion why their branded phone (SM-N910A) supports fewer bands than a non-AT&T branded phone (like the SM-N910W8).
Does iPhone have these restrictions... Just curious

Yes, the iPhone is also frequency restricted. Manufacturers do it to help carriers (which are their big customers, not us retail customers). Carriers use the frequency restrictions to curb cross-border sales and limit your ability to switch to a competitor, even if you paid for your device.
Iphone 6 A1522 (GSM)
LTE (band 1, 2, 3, 4, 5, 7, 8, 13, 17, 18, 19, 20, 25, 26, 28, 29)
Iphone 6 A1524 (CDMA):
FDD-LTE (band 1, 2, 3, 4, 5, 7, 8, 13, 17, 18, 19, 20, 25, 26, 28, 29)
TD-LTE (band 38, 39, 40, 41)
(I found the data in "Galaxy Note4 Firmware - All Models")
The version that ends in W8 is the Latin American version. The T-Mobile version is compatible with most bands.
Att has locked boot loader, as well as vzw. If your into rooting and flashing custom Roms, stay away from those phone's.

Thanks! I didn't know that. So now the AT&T version (SM-N910A) is definitely off the table. It's down to two models. Both will support all of AT&T LTE bands, but one adds full support for European LTE and the other adds full support for T-Mobile US.
SM-N910C, which has Exynos CPU and supports 800 Mhz and 4G band 20, which one of the three bands common in Europe.
SM-N910W8, which has Snapdragon CPU and supports 4G band 12, which means full support for T-Mobile 4G.

Yes, the T-Mobile version (which I see is the one you one) has the same bands as the 910W8 and the same CPU. The advantage (for me) is that I can buy it from T-Mobile and receive warranty.
The T-Mobile version is the appropriate one for you, especially since you will receive warranty from Samsung USA.

Please I'd love to upgrade from H+ to 4G speeds on my new Note 3. I saw this was possible for the Note 1... any chance this is possible for the Note 3?

Apparently it does. Great news.

Confirmed my carrier uses that frequency for lte and I indeed get LTE. This phone is killer.
