[Q] T989 or Galaxy Nexus (antenna & radio stack flexibility, using on other carriers)

[Q] T989 or Galaxy Nexus (antenna & radio stack flexibility, using on other carriers)
Hi,
I bought a T-Mobile branded T989 Samsung Galaxy S2. Now I'm hearing that there are limitations on the radio/network stacks pertaining to high speed access on ATT/MVNO networks.
So my question: Pertaining only to network/radio access,
* Is the Galaxy Nexus more flexible than the T989 (for a non rooted/base install ICS, 4.0.4)?
* Is the Galaxy Nexus more flexible in hardware, that is, if a new ROM is installed after rooting?
My desire is to get on ATT's network (maybe Straight Talk), because ATT has better coverage where I live.
I can't determine what radio/networks each have.
Nexus maybe?
* GSM/EDGE/GPRS (850, 900, 1800, 1900 MHz); 3G (850, 900, 1700, 1900, 2100 MHz); HSPA+ 21
* GSM 850 / 1900 ; WCDMA 850 / 1700 / 1900
T989 maybe?
GSM 850 / 900 / 1800 / 1900; WCDMA 850 / 1700 / 1900 / 2100

T-mobile Samsung Note 2 support 3G 2100 MHz?

I am going back to Thailand next year. I will get this Galaxy note 2 unlock and take it with me.
However, in my country has 3G on 2100 MHz with 3 main carries as follow.
3G
Carries name Band
AIS 1950 MHz - 1965 MHz and 2140 MHz - 2155 MHz
TRUE 1935 MHz - 1950 MHz and 2125 MHz - 2140 MHz
DTAC 1920 MHz - 1935 MHz and 2110 MHz - 2135 MHz
I was trying to understand what it says on box of Tmobile Note 2.
GSM Quad-band: 850/900/1800/1900 MHz UMTS: Band I ,band II, Band IV (Dual-band1700/2100 MHz), Band V
I don't get it much and I am not 100% sure that the phone does support 3G in my country.
Please some experts in here could help me confirm this. Would you please answer this for me? I appreciate every reply and thank you for your time.

I think you should be good to go... The International variant has fewer bands then we do on our T-mobile device so I wouldn't expect that you would have any troubles...:fingers-crossed:

A quick search reveals the following frequency bands in use in Thailand:
•AIS:
GSM 900, GSM 1800, UMTS 900 [VIII]
•TOT3G:
GSM1900, UMTS 2100
•DTAC:
GSM 1800, UMTS 850 [V]
•TrueMove:
GSM 1800, UMTS 850 [V]
The T-mobile Galaxy Note 2 supports the following frequency bands:
HSDPA: 850 [V], 1700/2100 [IV], 1900 [II], 2100
GSM: 850, 900, 1800, 1900
Judging by this, it seems like your best bet is TOT3G, DTAC, and TrueMove for UMTS functionality. All three of these have frequency bands supported by the Galaxy Note 2.

That's old information. These frequencies were used temporary.
They just auctioned the frequencies for 3G in Thailand. The auction is approved by Thai government. I have described the range of frequencies at the first post. But I am not sure it is in 2100 MHz. Any idea?
Thank you for reply.

Can anyone confirm about this?
and is T-mobile come with a unlocked bootloader?
If this is true... T-mobile would definitely have more sells (maybe just for the phone...:fingers-crossed

You're right

I found this information at Samsung USA website, but I think the Canadian variant (M919V) will be the same. The M919 for T-Mobile has those frequencies:
LTE: Bands 700 / 850 / AWS 1700 / 1900 / 2100 / 2600 ; HSPA+/UMTS: 850 / AWS 1700 / 1900 / 2100MHz; GSM: 850/900/1800/1900MHz

The T-Mobile phone will work no problem. I've posted the numbers elsewhere and they all match up.
However, Koodo is selling it for $625 outright and the other companies for $700, so the T-Mobile one is not any cheaper. All Canadian versions have an unlocked bootloader.

[Q] Unlocking T-Mobile htc one m8

I'm looking to buy a HTC One M8 T-Mobile version, and unlocking it.
I read on gsmarena.com that the frequencies that work on that phone are these.
GSM 850 / 900 / 1800 / 1900
HSDPA 850 / 1700 / 1900 / 2100 - T-Mobile
LTE band 4(1700/2100), 17(700) - T-Mobile
Now the frequencies in my country are
HSDPA 850 / 900/ 2100
LTE band 4 1800
If I unlock the phone will it be open from my LTE frequency in my country, and the 900Mhz 3g in my country,
or are the phones made for T-Mobile only work with those frequencies no matter if you unlock it or not.
Thanks in advance for all answers!

Unlocking it will not add or remove any of the phones frequency or protocol items.
Unlocking merely allows the device to use another sim card from a carrier that it was not branded for.
So if its a TMO branded unit and you unlock it you get all the features that TMO asked HTC to make the unit for them for, but you can use it with your carrier.
