Siemens SX66 From Cingular(PC20B1) No Sigal After Unlock

I'm desperately in need of help on this phone..Siemens SX66 from Cingular network in USA...I used the xdadev all unlock and it seems to finish unlocking OK..no more simlock..but the phone cannot pick up any GSM 900/1800 signal....can anyone verify that this phone should be triband or its just 1900mhz?...Or could it be from unlocking that causes this problem?...I know that other brand phone, xda IIs...is the same and has triband.....please help if you know the solution to this problem..thanks
900/1800mhz are NOT found in the US, only elsewhere. I am with cingular also and just purchased a Xda IIs, come to find out it has 850, 900, 1800 & 900/1800 mhz basnds but no 1900 mhz.
Seems Cingular uses 1900 and 850 only, but what I am able to gather the 850 is 90% of Cinular's coverage.
Hope this helps, I'm still trying to sort out my 850 situation and see if I should keep this phone, I sure do luv it.
Oh and by the way I think the SX66 is 850, 900, 1900 & 850/1900 mhz.

Quad band (or adding 850)

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

3G/4G frecuency

Hello, what frequencuy do 3G and 4G work on this phone? I wanted to know if its compatible with Argentina (I think it's 850 y 1900 mhz).
Thanks!

Is there really 2 versions of xperia s? (lt26i and lt26a)

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
https://fjallfoss.fcc.gov/oetcf/eas...alledFromFrame=N&application_id=917709&fcc_id
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

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.
