Siemens SX66 From Cingular(PC20B1) No Sigal After Unlock - Upgrading, Modifying and Unlocking

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

LG KS20 850 Mhz Band upgrade?

Hi everybody.
I live in United States and I have a KS20.
I really like my phone but work with the poor coverage of 1900 mhz of AT&T because I can't use 850 Mhz and I have low signal a lot of times and is very frustating.
BUT I saw a LOT of websites that sell the LG KS20 and they show in the specifications the KS20 with 850 Mhz Band support... I don't understand. Maybe is because a ROM / firmware update?
All this websites show the KS20 with 850Mhz Band...
http://www.alibaba.com/product-free/100190647/LG_Ks20.html
http://www.ipelagos.com/pd_lg_ks20_mobile_phone.cfm
http://www.handcellphone.com/archiv...sories-software-review-specifications-and-buy
Any ideas?? Any ROM that unlock this band? I had a Motorola L2 and Quad Band was activated with a unlock software that I bought on Ebay. I hope to do something like that with my KS20...
My LGKS20 (German) has the following options:
Automatic / UMTS / GSM 900 / 1800 and GSM 1900. I guess your hardware is the same.
the ms25 from brazil is quadriband..
if we just might extract the radio from it..

Activating Telus phone on Sprint network

Telus has just announced that they will be offering the iPhone starting next month. Since Telus is essentially Canada's Sprint, would it be possible to activate a Telus iPhone on the Sprint network in the US?
Sorry, answered my own question. Telus operates on both GSM and CDMA, the iPhone will be released on their GSM (HSPA+) network. I thought maybe they were releasing a CDMA version...guess I have to wait to see if Verison gets the iPhone when AT&T's exclusivity expires.
Isn't both techs?
I was reading the specs of the phone and it seems to be coming out with both.
These are the actual specs:
UMTS/HSDPA (850, 1900, 2100 MHz), GSM/EDGE (850, 900, 1800, 1900 MHz)
Doing some research the first set of codes and numbers seems to correlate to what sprint network is.

Unfortunately, no. Sprint runs on a CDMA (digital) network, while the first and second set of spectrum are all GSM (analog).

[Q] 3G NOT working on International Unlocked Version!

I bought the unlocked version (R800i) and im using it on a latinamerican network (MOVISTAR COLOMBIA) which is a GSM carrier but i can not get 3G speeds. Does it have to do with the supported bands? How can i change my supported bands?
BTW: This carrier works with GSM 850/1900 bands and according ro GSM arena it supports the following bands:
-2G Network: GSM 850 / 900 / 1800 / 1900
-3G Network: HSDPA 900 / 2100
HSDPA 850 / 1900 / 2100 / 800
Have you set up your apn settings

The r800i only have 3g 900 and 2100 hsdpa ...the 850 MHz hsdpa is only disponible in r800a and r800at model. Dont work 3g with your operator. Sorry the bad english.

I think what he's trying to say is you bought the wrong model.. Sorry dude.
hi guys having the same issue.
i have Xperia Play (R800i) running on Telekom (Slovakia). I asked folks over there on what frequency is their 3G running, they told me that 1800.
Does it mean that i will have just 2G (Edge) available if in my paper is UMTS HSPA Band 1 8 GSM GPRS/EDGE 850/900/1800/1900?
Telekom offered this mobile in the end of 2011 so I am curious whether they would offer mobile with no 3G capability.
Thanks
R800i: GSM (2G) 850 / 900 / 1800 / 1900, HSDPA (3G) 900 / 2100
R800at: GSM (2G) 850 / 900 / 1800 / 1900, HSDPA (3G) 850 / 1900 / 2100 / 800
The R800i will not work with 850 and 1900 bands. You can't change the support band, you'll have to buy a different phone. It is hardware limitation btw, if you flash R800at firmware and baseband to your R800i, it will not make it work.

thanks for your reply, if my provider is telling that its 3G is running at 1800 Mhz, it should run right? currently i am running just 2G :/ and even when carrier selection i have just 2g shown. Can it be SIM related? i have changed mine a week ago.
Edit: just checked in TMobile that lady ran my SIM on her phone and H appeared. it has to be phone related somehow.
how can i find out whether my 800i wasnt transfered from some at, a version?
I talked do Data centre and R800i was in one of the action of Telekom , when i select only WCDMA, i lose any access to the service, carrier told me that it has to do something with the phone.
I guess that there were 3G and 4G versions of Play, not the version without 3G
They already told you: You bought the wrong model.

Perhaps all problems will be solved at once if you bought the correct model?!

The 1800 is listed under both R800i & R800at as 2G frequency. I hate to say it but as its been stated already in this thread you bough the wrong model.

yep, this is what i wanted to confirm
is there any verion of Xperia Play running 3G on 1800 Mhz?

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

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
