[Q] Is it possible to flash different radios to gain GSM? - Galaxy Note 3 Q&A, Help & Troubleshooting

I've been at a loss on what to do with my Note 3 since moving to St. Louis. I was at first under the assumption that since it has a sim card slot it could be unlocked and used on GSM carriers and boy was I wrong. The USCC variant does not support GSM at all, and only operates on CDMA. I'm not accurate in my assumption but I assume that the US Note 3s all contain the same hardware but different radios flashed to the chipset preventing access to North American GSM. And now the challenge:
With Root and recovery access is it possible to flash a radio from a GSM variant and match the kernel and then subsequently a GSM Rom to turn the USCC into a GSM capable device?
To start I have found the following infoModes

LTE (4G)
750 Upper 700 (Verizon) / band 13 USA
1700 AWS / band 4 (IV) Americas
1900 PCS+G / band 25 USA

Verizon version doesn't support LTE 1900 / Sprint version doesn't support LTE 750, 1700 / U.S. Cellular version doesn't support GSM nor WCDMA

Which LG G2 are not compatible with Europe?

I want to buy a phone to a friend of mine in Europe but I have no clue that what frequencies are not compatible with the models of LG G2. I am excluding Sprint and Verizon models.
How about T-mobile and AT&T versions? Are they compatible and do they have a sim card slot?
Thanks in advance
All versions have a SIM card slot, but you'll definitely need to find out which frequencies your friend's carrier uses in order for us to be able to help you. You wouldn't want to buy a T-Mobile one and then find out you needed a Verizon one in order to get 3G in your carrier (happened to me).
If you don't know on which carrier phone will be used to check for bands and radio frequencies, AT&T LG-D800 is your best bet. It supports almost all of them excluding LTE bands.
I wonder what are the frequencies of T-mobile and AT&T versions? If I get them, I can find out the European frequencies. Any hint?

@Alex
So it seems both versions are compatible with Europe. Thanks man. Appreciate it.
The D803 Canadian version also includes some of the LTE European frequencies.

[Q] SM-gt900h T-Mobile???

I am about to purchase a Samsung Galaxy S5 GSM unlocked from HSN (the reason from hsn is because i can pay for the phone overtime instead of paying right up front). I am currently on Tmobile with my lg that uses hspa+ 42 and i wanted to know if i would get tmobile "4g" 42 megabit speeds on the S5 considering the fact its international with an octa-core processor?? Or would I be stuck with edge/2g??
Bands:
T-Mobile version: HSDPA 850 / 1700 / 1900 / 2100 - SM-G900T
G900H HSDPA 850 / 900 / 1900 / 2100
The only difference is the 1700 band that is missing from the H variant.
This thread might help, I think that by having the 1900 band you'll be OK for HDSPA if you are in an area that has refarmed towers, but better read it all the way through (I didn't)

You won't have LTE of course.

G3 Frequencies Table

I'd like to compile a table of the radio frequencies used by each variant of the G3: seemingly, there is a lot of over-lap and curiosity, leading to many questions about which variant works on which network (including me!). Please check on your phone the usable radio frequencies; then fill in the template:
Model:
Country: Carrier:
2G:
3G:
LTE:
Notes:
Model:d850.
Country: USA Carrier: Att
2G: 850 1900 pcs
3G: 850 clr 1900
LTE: 700bc MHz 1900 MHz
Notes: my area in North Alabama uses band 17 or the 700 b and c block. I only listed what Att supported as it would be pointless to add what they don't.

Buying the SM-N910W8 need help to understand some things...

I'm going to buy the Samsung Galaxy Note 4 SM-N910W8 from amazon.com, I seen that's the canadian version. The buyer says that's compatible with all GSMs worldwide, not only in North America. As I'm from Argentina, and the bands in Argentina are GSM-850 and 1900 MHz, does it work here? Also, the 4G LTE is coming to my country by the end of next year, with 1700/2100 Mhz and 700 Mhz bands for it. Does it work here?
GSM Arena says that the SM-N910W8 is compatible with:
3G- HSDPA 850 / 1700 / 1900 / 2100 - N910W8
4G LTE- LTE 700 / 850 / 900 / 1700 / 1800 / 1900 / 2100 / 2600 (Bands 1, 2, 3, 4, 5, 7, 8, 12, 17) - N910W8
As I don't know about this (never seen the compatible bands when I buy a phone as it's the first time I buy one from USA), I don't understand if that means that's compatible or not.
Other question: What SoC does it have? Snapdragon 805 or Exynos? If it's Snapdragon, does it means that's compatible with Roms of other models?
Help please! Thanks!
If you can live with (potentially) reduced lte coverage then no reason you shouldn't go for it.
If you want to ensure maximum coverage then you should really find out what 700mhz band is to be used in your country (band 17 or 28).
Acording to Wikipedia 700MHz band 28

Which version of Samsung Note 4 phone is a better buy? SM-N910A vs SM-N910W8 [Moved
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)
Thanks to everyone, I just decided to buy the N910C version due to I'm sure that it will work in my country (as it's the model that will come here officially). "Preparing for Shipping" says Amazon, I cannot wait!

Yes, I just want to verify that I'm not missing anything.
the 910U is better for you. its exynos and works well in north america and europe and most of asia.
That's right. According to Samsung, SM-N910U supports LTE on "B1(2100),B2(1900),B3(1800),B4(AWS),B5(850),B7(2600),B8(900),B28(700)". In Europe, bands 3, 7 and 20 are commonly used.

unlocking Yureka?

can we unlock Yureka to be able to use a SIM card from a different carrier? like EMTEL?
anyone? any inputs?
YU Yureka isn't locked to any particular carrier.
Yureka supports the following bands:
2G bands GSM 900 / 1800 / 1900 - SIM 1 & SIM 2
3G bands HSDPA 900 / 2100
4G bands LTE band 3(1800), 40(2300)
Emtel operates on:
2G Bands: GSM 900
3G Bands: W-CDMA 2100
4G Bands: LTE 1800
So there shouldn't be any problem.
Thank You so much Titokhan
