I just bought a SX56 and was using it with T-mobile service. I switched to Cingular and when I put my sim card in, I can't get a signal. I have tried to change the gsm bands but even this doesn't work. Can someone please help because I love the features of this phone and don't want to go back to a normal phone.
Have you unlocked it?
Yes it's unlocked. I've tried it on all bandwidths and it won't detect cingular network. When I manually do it it won't save or work when I put cingular's network at the top of the list.
Cingular operates on 850/1900 and some world phones on 1800 to. What is the problem I may have. Can I not use my SX56 with cingular?
you should be able to use a t-mo radio stack on a SX56 to get signal with Cingular GSM. You may have change the radio stack if you are still using AT&T radio stack. Cingular is still converting TDMA to GSM in some areas. While to-mo has allways been GSM in the US. Rare poss explination: AT&T selling GSM SX56 in your area that they have recently gone GSM in. You a t-mo customer bought a gsm phone and used it on another gsm providers network, then attempted to switch to Cingular which may not have gone GSM in your area. If you went into a Cingular store and they gave you a SIM card they should have gsm coverage. If this is the case I would bet your radio stack is still AT&T's so try changing to t0-mo stack and see what you get. Search this forum for links under ROM upgrades or try yorch.net.
Since we are on the subject oes anyone know where to get a generic worldwide radio stack for the XDA1 like on the i-Mate(s)? :?
I tried to download radio stacks from yorch.net and get error pages. Any other ideas? I lost and I really like this phone.

It depends on the area you are in for Cingular, most of their GSM operations are on 850 which the SX56 won't work on. If you are in the Carolina's I know it will work, but the other areas outside of here depend on the area. If you ask Cingular about it they will probably tell you it won't work. I would just ask Cingular what freqs. the towers in your area support. That will tell you for sure whether it will work or not.
Siemens sx 56.... cingular
Same here.... My sx56 reads "NO SERVICE"... I was not sure if it was the sim or not so I took it to a local Cingular Dealer and the tecnician took my sim and inserted it to a Cingular cell phone and the service came on... Inserted the sim back in the Sx56 and again "NO SERVICE"
Things Ive tried ....
- reset the SX56
- went to boot loader mode (ver ver 5.22) and did the GSM Audio test and this produced a load audible sound
- went back to the bootloader mode and selected the GSM 900, 900/1800, and 1900 and still "NO SERVICE"
- then I thought.... could it be locked? inserted a Tmobile sim again and the service came on... NOT LOCKED
MAN... WHATS going on!?!?!? previous to this Cingular service I had Tmobile which worked like a breeze... WAP and ALL!!!!
Any IDEAS anyone???
AND a BIG CONGRATS>>>>>> to the developers putting all this effort on this product and on such a COOL looking web site.

XDA1 issues with Cingular
OK, here is my life story:
I purchased the XDA from ATT Wireless but want to use it on Cingular, so I unlocked the XDA and it working fine with the Cingular SIM. (However, the network XDA picked up is T-Mobile and not Cingular). And the XDA works great in my hometown Houston, Texas.
I then travel to Indianapolis, Indiana, as soon as I got out of the plane, switched on the XDA, and got a signal for celluar service. Great so far.
When I get to my office which is 60 miles southeast of Indianapolis, I got no signal. When inquire the available network, I can see several Cingular networks listed on top of the drop-down list, and then ATT Wireless, and then T-Mobile, but the XDA won't be able to register to any of these networks??? Then funny thing is this is the place where I signed up with Cingular service.
When I contact Cingular, the representative said that the XDA appear to work while roaming onto other networks, but it will not in the local Cingular service area. She said that my PDA phone is not compatible with the local network. Is this possible?
Originally, my RS version is A.20.10, I then upgrade to A.33.02 in hoping to resolve the problem, but no luck.
I'm now trying to upgrade my RS to T-Mobile 6.24.00 from yorch.net but when unzip the file, it asks for a password. Does anyone know what the password is???
Am I going in the right direction to make my XDA usable in a Cingular network?
I am having the same issue getting my unlocked T-Mobile PPCPE to register on a network when using a Cingular Wireless SIM in the Atlanta area.
The phone can see both T-Mo and AT&T networks when using the Cingular SIM, but it will not register one either one of them...? It does not see the Cingular network however, as I believe that Cingular is using the 850 band, with roaming agreement in place with T-Mo and AT&T.
I am using the WM2003 ROM and radio versions.
Any ideas why it will not register on the T-Mo or AT&T network, even though it "sees" them...?

I am a Cingular customer care rep and I can tell you that the XDA will not work in the Indiana or Atlants markets. Reason being is that those markets are 850 and has no signs of being 1900 atleast until the AT&T buyout happens.
I am in South Mississippi and when we go GSM it will be 1900 but if I travel back to New Orleans I get no Cingular service because it again is another 850 market.
At this point the only 1900 GSM markets we have in the Southeast US is the Carolinas, Mobile, and South MS. Everyone else is 850.
Many thanks for the response. The curious thing to me is that if my device can accutally "see" the T-Mo and AT&T networks when it has a Cingular SIM installed, why won't it let me register on those 1900 Band networks? It seems that the Cingular SIM is somehow locked to the 850band and prevents the device connecting to any other network.... Is it because that where a Cingular 850band network exists, Cingular does not have roaming agreements in place with the other providers in that area? Do you know if the Cingular SIM could the SIM be programmed/enabled on the network side to allow a connection to a 1900 network?

I have thought the same thing at times and unfortunately I can't say one way or the other. I do know that with my XDA when I travel back to New Orleans I lose signal literally when I cross the state line. I am buying an 850 capable phone soon so I can test my theory out and see what can be done.
Does your say unable to register on network too? When I switched my band to 1800 for some reason I was able to see the Cingular network on the phone but again not able to get on the network.
yes, excatly, "cannot register on the network"... I have a "wild" theroy that says if I get a SIM from a Cingular store in an area where they have a native 1900 Band network, it might be set up in such a way to let me roam in the Atlanta area...? The other question I had that you may be able to answer is do Cingular sell any GSM phones that do NOT have the 850 band, or are all the Cingular GSM phones now 850/1900/900 ?

I can squash your theory on the SIM right now because I have an active sim from a 1900 market and it still don't work.
As far as the 1900 only phones, we haven't carried them in about 2 years because the Carolinas and California were our only GSM markets for a while and we had no need for 850 but now all we have is dual band or higher for 850.
Ok, many thanks. That will save me a trip to the Cingular store in Ohio when I am there next week So, a Cingular SIM will work in any Cingular dual band (or higher) phone allowing it to switch between available 850 and 1900 band networks that are operated by Cingular. In the case where a Cingular network is present, will they let you pick another carriers network (say AT&T) or will it force you to the Cingular network every time?

It always will look for Cingular first but then go from there to a certain list of carriers and if those are not found it says to hell with it and takes anything it can get.
Hmmmm... still a mystery then, as my PPC PE could see both AT&T and TMo networks when the Cingular SIM was in it, but was unable to connect to either of them...? I have some contacts in the Cingular IT organization in Atlanta, so I'll see if they can shed any more light. Will let you know what I find out.
I feel your pain
If you think your experience is frustrating the plot thickens.
I'm in South Florida.
I have a TMobile that I unlocked middle of last year (Aug/Sep 2003) put in a Cingular SIM and worked perfectly (Roaming on the TMobile 1900 network) then a few months ago I had a lot of Outdoors, rugged type activities planned so I decided to pamper my PocketPC and put the Cingular SIM back into the "disposable" Cingular GSM that I got for a penny
Well days turned into weeks and months so a few days ago I decided to put the SIM back into the PocketPC. When I did, I got a "no signal" from both SIM's. I tried setting(bandwidth) and testing the GSM through the bootloader etc. You name it I tried it . I eventually upgraded to the TMobile WM2003 ROM and Radio Stack in desperation. And you guessed it...No joy. I get "NO SERVICE"
I know Cingular down here has migrated to the 850 but I don't know why roaming on TMobile 1900 has been disabled.
So in a nutshell: Cingular SIM used to work in a TMobile XDA up to a few months ago and now doesn't.
I have a strange problem!
I have an O2 XDA II, (unlocked), original ROM (1.03 USA), which I'm using with a UK Vodafone SIM. This works fine in the UK, however I am currently in the US trying to roam, without any luck. The automatic network selection does not connect to any network. Using manual network selection, I can select the T-mobile network, which it connects to, with good signal strength, but if I try to make or receive a call it does not work. It also loses the connection altogether after a few minutes. (This SIM works fine in the US in my Motorola tri-band phone). However, if I use my wife's US T-mobile SIM in the XDA II instead of mine, it works fine!
Any ideas?? All help would be gratefully appreciated!
Paul
phone networks must have agreements to let users roam
Vodafone certainly have a roming agreement with T-mobile in the US - I've been using this SIM in a triband phone in the US for years.
Paul
well are you talking about roaming of grps ?
because there are not as many agreements when it comes to grps as there is when it comes to std phone
No, just roaming GSM voice!
Paul
Dear All
Is it possible to use the XDAII on the Three network within the UK (ie will a Three sim card work in an XDAII and allow you to access the Three services)?
Many thanks
Anon
if you mean the company called 3
then no their brand is because they use 3g / umts tech
where xdaII is 2g only
also the company 3 even if their sims support 2g on their 3g phones
when no 3g service is present block other 2g phones from using them
Thank you for answering so quickly Rudegar.
I did mean the Three (3) Network in the UK and therefore appears I will not be able to use a 3g SIM.
Never mind - now need to weigh up if the network offer for 3 is worth getting while loosing my XDAII or keep XDAII and keep looking for a new offer from one of the other networks.
Anon
Unlock XDA II to ANY Network!!!!!!!
Just put this file on your root folder of your XDA II and run it and when you put another sim in from any other network the unlock number will be 8 zeros. Easy as....
Support for any network any country!!!... Even three (3)
Happiness
Thank you - my XDAII is already unlocked (may be with your attachment or another off this site a few years ago). However, I was specifically interested in whether the phone would work on Three 3g with all their functionality (not 2g, which I believe it would be forced to as Three's back up - currently o2 but moving to Orange).
Many thanks

Hi,
I rooted my X10 the day it was released, but never put my simcard in it (N900 user).
I did today, went to google maps (and all other) and no network.
Went I got the X10 (Last Friday I think), when I put in my SimCard the SE based software automatically setup my network.
Could you please help get my networking back?
I need my 3G!
GSM works for basic sms and calls.
My network is:
OPTUS Pre Paid (Australia)
Please!!
You probably need to enter the APNs in Settings->Wireless->Mobile Networks. I think the optus ones are listed on the ausdroid website.
Here is PDF for 3G and other settings of OPTUS AU
Keep it simple guys...this is what I did to get my 3G service back up.
Menu button -> Settings -> Wireless controls -> Mobile networks -> Auto Internet settings.
Once you have done that, your X10 will pick up your GSM provider's 3G settings for you.
Alohas for now.
with optus, i normally had to call them...
I'm with Optus too. Just used the automaticAlly detect settings function. Worked perfectly.
Sent from my X10i using XDA App
