I just stumbled across this old thread.
http://forum.xda-developers.com/showthread.php?t=265606
Is the possibility of this true?? Has anyone tried to do work on the Radio ROM to bring in Quad band? I would pay to have 850 available for my phone.
Comments?
Has anyone tried an Athena radio on the Universal ( I presume yes, still looking through the forums ). And what about the HTC Sable? They both use the same CPU and the Sable in particular has comparable ROM sizes.
Quote from one of the links:
QUALCOMM's MSM6250 chipset solution helps enable worldwide roaming for
WCDMA (UMTS) terminals. The MSM6250 system solution supports dual-mode, quad-
band GSM transceiver operations [GSM 850, GSM 900, Digital Cellular System
(DCS) 1800, and GSM 1900] and WCDMA (UMTS) transmit operations for 800 MHz,
1900 MHz and 2100 MHz.
Shouldn't the Universal therefore be able to do 850 with a change to the radio ROM? Do the HTC Sable and Athena use the same chipset?
Can anyone help us?
It would be great to have a 850 band for my SPVm5000. Hope anybody can answer your question. Seems that since this phone was only released for europe and not USA the quadband was not open

I am having a question about the Radio.
I saw the radio thread. There are a quad bands radio. Now, My phone doesn't have UMTS 850 (no 3G support at North America no 3G Icon on the top of status bar). If I flash the quad bands radio, should I get the UMTS 850 3G support?
The short answer is no. The Euro/Asian Diamonds that came out were tri-band gsm and Euro/Asia 3g support. Later an update was released to make them quad band gsm. This was possible because the actual hardware was quad band, it was just locked down. The 3g chip is not triband, it is different in the different diamond models (NAM vs euro/Asian). So while you can make any diamond quad band gsm (if it wasn't to start with), you can not expand the 3g freq because the chip is not in your phone.
Thanks.. I see. Hardware !!!!
In the development thread DooMLoRD mentioned that the phone comes in two versions. There seems to be confilicting info about this. I have seen sites say it is quad band HSDPA and there is not 2 different models and only the lt26i. I would like to import to the USA and use on ATT 3g. It looks like the lt26i will work on att 3g. Below is the info listed in the development section of the site.
Model number:
The Xperia S has model number as LT26 and has two models LT26i and LT26a. They differ in the spectrum of frequencies supported for 3G/WCDMA http://www.gsmarena.com/sony_xperia_s-4369.php
LT26i - HSDPA 900 / 2100
LT26a - HSDPA 850 / 1900 / 2100
The items passing the fcc was the LT26i and it was listed at quad band UMTS/HSDPA

It is also mentioned in this engadget article
http://www.engadget.com/2012/01/27/sony-xperia-s-jogs-past-the-fcc-carrying-plenty-of-atandt-t-mobi/
I've pre-ordered the Xperia S LT26i from here. If you scroll down a bit and switch to the specification tab you'll see this:
GSM/GPRS Yes
Frequencies 850/900/1800/1900 MHz
Speed GPRS up to 86kbps, EDGE up to 237 kbps
3G/HSPA Yes
Frequencies 850/900/1900/2100 MHz
Speed HSDPA Up to 14.4Mbps, HSUPA Up to 5.8Mbps

It seems like it supports both frequencies... It'll surly work in Europe right? I live in Israel using Cellcom, I hope it'll work fine.
I am wondering the same thing too!
I live in Canada and I want to get this phone but I know Canada will be the last to get it.
Is the ' i ' version going to work for me in Canada?
Please help!
Thank you.
check the Xperia S whitepaper
http://dl-www.sonymobile.com/cws/download/1/105/035/2/1327908899/Xperia_S_WP_2.pdf
"LT26i UMTS HSPA 850 (Band V), 900 (Band VIII), 1900 (Band II),
2100 (Band I)
GSM GPRS/EDGE 850, 900, 1800, 1900"
so it's safe to say there is going to be only one version?
if so, I will order my Xperia S and start using it in Canada!!
From what I have seen for the last three months, only one version which is quad band. Today I ordered one from ebay shipping from Hong Kong and I should be receiving it next week sometimes around Thursday. I will report back once I have it.
EDIT:
for people interested, this is the place I ordered it from http://www.ebay.com/itm/Sony-Ericsson-Xperia-S-LT26i-Unlocked-12mp-32GB-Android-Phone-White?item=150770279921&cmd=ViewItem&_trksid=p5197.m185&_trkparms=algo%3DRPSI%252BSIC.NPJS%26itu%3DUCP%252BUA%252BMAGEXP%252BI%26otn%3D12%26pmod%3D190644185862%26po%3DLPV%252BLVI%26ps%3D63%26clkid%3D6745036511139896139#ht_3032wt_1396

This.
White paper clearly states HSPA 850/1900 is included. And FWIW GSMArena corrected the specifications page to reflect this http://www.gsmarena.com/sony_xperia_s-4369.php

I have ordered one from Clove in the UK. It should be shipped Mon or Tue.
I will report back once I either trim down my SIM card or buy a micro SIM.
I am on Telus now running an unlocked generic Xperia Arc.
Cheers
I can confirm it is a quad band. It supports UMTS/HSPA Bands 1/2/5/8. See screenshot from my service menu.
PS: the phone is unbelievably awesome.
I know this thread is old.. but my xperia s only gets edge internet conection..! D: No 3g at all! I'm in Bolivia btw. With "a" versions of other xperia phones I was able to get 3g internet connection.. why is this happening?
The 'a' and the'i' signify different versions of Baseband. The baseband determines which 3g network you connect to ! Make sure you pick up the right instrument otherwise you wont be able to connect to 3G. Google "3G baseband" + your Country and then see which model, the a or the i supports that baseband Wrong baseband => No 3g
Dear xda Members and / or galaxy note 2 Users,
I'm a bit confused about the various versions of the Note 2.
In a few days I'll visit Florida and intend to buy the LTE version from Walmart.
ht.tp://ww w.walmart. com/ip/Samsung-Galaxy-Note-II-Smartphone-Titanium-Gray/22374238
(I don't know if shoplinks are allowed, but you can't buy it directly here and i hope you can accept it anyway this time)
However, I need to know whether the phone works in Europe/Germany and with which communication standards.
Is there a difference between the US and European GT-N7105?
on ht.tp://e n.wikipedia. org/wiki/Samsung_Galaxy_Note_II i found various versions called
AWS phone
CDMA/EV-DO phone
TD-SCDMA phone
Dual-cell HSPA phone.
and the LTE where they tell that it would be kind of an "International" phone.
"Most of the variants support GSM/GPRS/EDGE in the 850 Mhz, 900 Mhz, 1.9 Ghz, and 2.1 Ghz bands; and UMTS/HSPA+21 in 850 Mhz, 900 Mhz, 1.9 Ghz, and 2.1 Ghz"
Does the version i found on the walmart page support UMTS? there are only specifications that it can handle GSM and LTE, but not which LTE Bands.
(I think I need support for 800 MHz, 1800 MHz and/or 2600 MHz in Western Europe)
correct me if i'm wrong with any statement and enlighten the confusion for me if pssible
Thanks in advance !
PS: I'm not allowed to post outside links here, so I addet space characters before .com and .org and in the www and the "en" and dots between the ht.tp's. remove them before copying.
I see that the T-Mobile LTE version is available in the US on the play store. It is significantly cheaper than in the UK.
I bought the v1 WiFi nexus 7 in the US and had no issues. If I buy the LTE version from the US can I assume that I can use it on a UK mobile network without issue? I presume both are gsm and there is no issue?
Thanks

Even GSM networks operate on different frequencies on different continents. LTE networks may have other frequencies than GSM networks.
I found a (german) comparisation list for LTE frequencies. For US, there are 700, 1700, 1900 and 2100 MHz listed; for UK there are 800, 1800 and 2600 MHz noted.
So, if you buy an US version, it will be useless in UK. Besides the useability, you may have to pay taxes on import, additional to p&p. Will it still be cheaper then?

For France, same frequencies than UK.
We will use someday 700 MHz also.
Some of us are waitin 4 an Euro LTE Nexus 7.
I found something about the Nexus 7 ... on http://www.google.com/nexus/7/ .
Scroll down until you see a link "Tech Specs". Open it and scroll a bit down; all GSM, UMTS and LTE frequencies are listed for different world areas.
The US and the EU version share most LTE frequency cpabilities, but the US version can operate on 700 and 750 MHz (which the EU device can't use) while the EU one can operate on 800 and 2600 MHz (which the US device can't use).
So it depends on your carrier's frequencies if you can operate an US device in UK or not.

My brother is over in the US next week and could therefore bring it back without P&P and most likely other charges.
In the UK the price is 320 GBP so the saving is around 100GBP with the currency conversion.
Currently I have my mobile with T-Mobile and a sim that I use in a mifi on Three. I am looking to move the Three mifi sim into the Nexus but I don't think that looks like it would work as it states they will use 800 and 1800. I presume that both frequencies are used?
The US device can't use the 800 MHz band, but the 1800. Maybe your carrier operates LTE at 1800, maybe not. Can't say that from here (Germany).
Going to take a chance. The US price for the LTE is cheaper than the WiFi only in the UK. Will advise how I get on

Same here Czech rep, 32 gb lte is the same price than 16 gb wifi here. But i need the 3G/4G internet can't risk it i must know
Aidenbree: this is exactly what i was thinking of doing too, so thanks for asking the question! I'm also on Three and would be really interested to hear how you get on. £100 saving is worth thinking about!
are they have different hardware ?
North America:
GSM: 850/900/1800/1900 MHz
HSPA+: 850/900/1900/1700/2100 (AWS) MHz (Bands: 1/2/4/5/8)
LTE: 700/750/850/1700/1800/1900/2100 MHZ (Bands: 1/2/3/4/5/13/17)
Europe:
GSM: 850/900/1800/1900 MHz
HSPA+: 850/900/1900/1700/2100 (AWS) MHz (Bands: 1/2/4/5/8)
LTE: 800/850/1700/1800/1900/2100/2600 MHz (Bands: 1/2/3/4/5/7/20)
or only radio software different?
if they just use different radio, it may work by change radio

Surprisingly, the radio software is the same, in fact everything software wise is identical between both devices, there is but a single firmware for both devices. I am not even sure if the US version can't technically use band 7 and vice/versa, has anyone tried to connect to a LTE network in the EU using a US LTE Nexus 7 ? Maybe those specs are just "limited" to comply with FCC/EU regulations/certifications (Paying for the CE certification for a specific frequency can be expensive)
If there is a difference then some flag must be set hardware wise to tell the radio what frequencies it can tune to.

omg
the radio is the same
seem they fix the band though hardware
any chance the software detect the mobile services provider to decide using which band
Hi All,
I bought an Oppo Find 7 x9077 which doesn't support the 1700 MHz band that is used by T-Mobile/ATT and most other major carriers in the US in order to get LTE.
My question is, is there a way to unlock the 1700 MHz band using software or firmware flash or is the limitation on the hardware side?
Thanks,
Colin
The 1700Mhz band is not supported by hardware on the X9077.
I see, thank you for the reply!
