Odd observation while comparing Sensation (Rest of world) vs. Sensation 4G (T-Mobile)

While surfing GSMArena.com I decided to use their side-by-side phone comparison tool. To my astonishment I found that the Euro vs. NA versions of these phones have different standby and talk times; mind you they have the same exact battery. Take a look at the screen shot I provided outlining the times.
Only noticeable difference (to me) is the 1700 Mhz band on the NA model for T-Mobile use. As a result this has me wondering what could cause these discrepancies? Is it because of network strengths/weaknesses and infrastructure?
I'm no engineer so this is just a shot in the dark and would like someone to chime in
Thanks in advance.

That's most probably a typographic error. Look carefully and you will notice that they're just the same, but inverted for 2G/3G

Lol hehehe

the 1700 band is so you can have countionious up and down data on hspa+ you cant do that on eurpean modle

close. the AWS band is actually using both 1700 & 2100. 1 is for downlink & the other is uplink. Don't remember which is which though, you'll have to look that up yourself if you want to know.
Also, both the EU & US versions of the phone have the AWS band

@xboarder56 and xnifex, your actually both right. T-Mobile USA added a second band (1700) to be able to do full duplex mode with data. Faster data rates and your phone uploads/downloads data simultaneously. FYI, 2100 is downlink (transmit from the cell site to the phone) and 1700 is uplink (transmit from the phone to the cell site).

Nexus Prime for AT&T and T-Mobile? [FCC]

Looks like the FCC passed off on a GT-I9250 Nexus Prime / Galaxy Nexus for AT&T. It doesn't sport AT&T LTE, but does have HSPA+. This makes me smillllleee!

Update: This might support T-Mobile 3G, too. I guess AT&T and T-Mobile were really expecting that merger to slide through. http://www.wirelessgoodness.com/201...e-hits-the-fcc-with-support-for-att-t-mobile/
Update: Looks like there’s no test for the 2100 MHz spectrum for T-Mobile. That means that T-Mobile support is unlikely.

sweet!
it's coming soon....

Drat i was hoping for AT&T/T-Mobile support like the T-Mobile Ruby and Galaxy S 2 and it saves them production costs (apple) from making various models. Hopefully it will support canadian LTE when they come up here

Rogers uses those (non lte) bands also...

The 2100MHz band doesn't get tested in FCC filling since it's the Rx band. My Touch 4G didn't have 2100MHz band test results but I bet it has T-Mobile 3G connectivity

Here's a summary:
GSM 850/1900: (AT&T and T-Mobile 2G/EDGE)
WCDMA/HSPA 850/1900 (AT&T 3G/"4G")
AWS/HSPA 1700/2100*: (T-Mobile 3G/"4G")
*AWS 2100 is not tested by FCC so it won't show here. We can assume full AWS support, not upload only, that wouldn't make any sense

That's awesome! Thanks guys. Guess they were expecting the T-Mo AT&T merger to go through.

Travelling to Thailand? Here's a guide for choosing networks.

If you're travelling to Thailand very soon, and you want to access the internet, keep in mind that there's very few places that allows you to get free wi-fi without any subscriptions or SIM card (like in many shopping complexes that need a SIM card for wi-fi), or you'll need to spend time to register for free wi-fi (especially Suvarnabhumi Airport (BKK - Bangkok) that I see one person registers their wi-fi for ten minutes, but the airport's wi-fi is incredibly fast) so that if you want to use the internet in all places, you'll need a SIM card for that.
And if you want to buy a new SIM card in Thailand, DO NOT believe in their advertisements. In Thailand there's one network that claims that their 4G LTE is fast, but of course they're slow and has very weak signal, and when the signal is weak, and you only have 3G (which is HSPA+), it's only 0.2Mbps - 5Mbps. See below for consideration.
1. True Move H
Don't believe that their 4G LTE and 3G HSPA+ will be fast as you expect. Their signal is very weak and not nationwide, and on 3G it's nationwide, but you'll get slow speeds (although you have very strong signal).
Their tourist SIM is 299 Baht (which is considerably expensive) and you have 1GB internet, which will slow down after being used up.
Their staffs are terrible and I don't have any words to describe, go try at your risk.
You'll need a phone compatible with UMTS/HSPA+ 850MHz/2100MHz and may include LTE 2100MHz. But don't care about this, their network is slow.
2. dtac
Even though their 4G LTE is not very fast compared to other networks, but their 4G LTE is stable and smooth. 3G HSPA+ is faster than 4G LTE so that you'll want to try out. The network is available in most areas with some blackspots, but thanks to their tower-sharing plan with AIS, another network, after confirmation, the signal WILL be better nationwide (but not now). Their 3G HSPA+ is based on the dual-band network like True Move H, but this network (dtac) has more performance.
Their tourist SIM is 299 Baht that's enough for 1.5GB internet (and will slow down after this). There's also 599 Baht for 4GB internet (and also slow down after this).

You'll need a phone compatible with UMTS/HSPA+ 850MHz/2100MHz, GSM 1800MHz DCS, and LTE 2100MHz. I highly recommend this as I have best 3G speed on this network (highest speed was 26Mbps, average is 10-16Mbps) and not on any other networks.
3. AIS
Due to their 3G HSPA+ has only single-band, their network is slow, and they've made more cell towers & small cells in particular areas, BUT as I've told you earlier, AIS had plans to share their towers with dtac, so soon, AIS will have faster network, but I won't recommend you to try since their network is slow (but have high performance equipments).
It's hard to describe anything about their tourist SIM, but you can find info here: http://www.ais.co.th/roaming/visiting/sim-for-traveller-en.aspx
Their network only uses UMTS/HSPA+ 2100MHz, that's why I told you that AIS is slow, and they consist of GSM 900MHz where they'll abandon their service soon.
====================================
NO networks in Thailand that use CDMA (actually there was, but they abandoned since April 2013) so that Verizon & Sprint phones won't work, and AT&T uses different bands, so that T-Mobile and off-contract phones MAY work.
Thanks for reading this thread and have a good day choosing SIMs!

Xiaomi Mi 4

Does anyone know if this Mi 4 or any of the other phones work out of box in canada?
If not, is there a way to get it working on LTE ?
THanks,

Only LTE bands it has out of the box are 1,3 and 41. I am on AT&T in US and no LTE. Edited NV values successfully but no additional LTE bands were enabled.

That is unfortunate to hear, what is the fastest connectivity you're getting?
I'm on the AT&T equivalent in Canada known as Rogers.

About 7MB/S which is terrible. I like MIUI and this device is nice quality. Dare I say it has the feel of an iPhone but is loaded with Android so the best of both worlds (I personally detest the closed source IOS). So I'm suffering with no LTE just to use the MI4 but I've got a ZTE Axon for a backup if I need a LTE compatible device. Always near WIFI so it's not often. I will say, no dropped calls or texts with it and I've had it a couple weeks. Call quality is excellent.

Best you can get is 3G or H+. Also in Canada on Fido

dont buy the chinese LTE edition. i hear that does not even do 3g. the wcdma (w) variant does 3g/H+

I have the China Union LTE model and it has 3G on AT&T.

I am not doubting you. But there are 2 LTE variants.

TDD LTE <<< GSM 2G ok but no WCDMA 3G
FDD LTE <<< This is the Western one with WCDMA (3G) support

LTE Bands on an N920T

Going by the specs I've seen on a number of tech sites, I've always thought that the LTE bands on most T-Mobile phones were limited to those that T-Mobile and AT&T use (4 and 12). However, when I ran "search for operators" I could see Verizon (and ATT + TMo) towers. Then I found this page at T-Mobile's own website that shows this:
InternationalQuad Band GSM; LTE: 1, 2, 3, 4, 5, 7, 8, 12, 20; UMTS: Band I (2100), Band II (1900), Band IV (1700/2100), Band V (850)​​
The UMTS bands obviously are TMo's, but LTE covers way more than they have deployed. So it would seem the N920T really has these bands? Perhaps it's because the chipset is Exynos.

You can see and change the band's from the dialer using *#2263#
I don't recommend changing them but you can look at the list.
I did change the default bands to LTE/WCDMA/GSM on mine for use on AT&T

That's interesting. When I execute that USSD, it shows way more bands than I quoted from TMo's spec list:

}
And this continues into the 40s, I just can't remember how to screencap the entire page. I am curious if they are all actual bands you can use, or (I would assume at this point) every possible LTE band there is. But it's a feature code I haven't seen before, so +thanks.

Well, after further digging in the *#2263# screens, this definitely looks like an international kind of phone.
If the settings are to be believed, there's also support for TD-SCDMA, which is an alternative to W-CDMA (and incompatible with it). That's used in China, which is a long way off from T-Mobile territory.
But that's great -- such an enormous frequency list is exactly what a flagship should offer. And it's probably no coincidence that this is an Exynos chipset, because other phones using Qualcomm seem to have restrictions in place for the US market.
