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.
Hi, there I just received my XDA EXEC for UK, Im in USA.
I have Cingular Wireless(AT&T Wireless), and what I did was put the Sim card on the phone and the phone starts working, but I'm having 2 problems.
First my phone has the roaming signal all the time, I don't know if there is any way to modify that.
And the second and most important is that the phone has really low signal.
I want to know if someone can help me.
Thanks.

Hard reset the phone and choose Copoorate mode (the code is 0506). This will stop the roaming issue. Other modes load O2 customisation.
I already has my phone in corporate mode and still the roaming signal.
Thanks.
COPYTECHUSA.
If in roaming then it would suggest that the phone has been setup with UK O2 as the default network. Have a look at Settings/connections perhaps you can change the defualt network to Cingular or try installating the Cingular CAB file from: http://www.howardforums.com/showthread.php?t=787912&highlight=cingular+cab
I have no idea what I'm saying here, but try to lock it onto GSM instead of WCDMA and it should be better.
We have six WM6 devices here at work on T-Mobile. This summer there was a flood in town and one of the towers was damaged and "repair". However, since then all T-Mobile phones in our area have roamed MUCH more than before. While this isn't a problem for phone calls (although voicemail messages are delayed as are SMS), we are now seeing a problem with WM devices. We've had T-Mobile engineers down they have worked with the local roaming partners but the problem persists.
When you roam off the T-Mobile network, and then come back to EDGE, you never make the data connection. The big E shows that EDGE is available, but if you force the connection with ActiveSync or IE, you get this error:
The remote party has ended the connection.
You can resolve this by either turning off the cellular radio and turning it back on, or resetting the phone entirely.
The T-Mobile engineer told me that the problem is that they don't have any data roaming partners, however when our phones are roaming, the local GSM roaming partner, is allowing the phone to make a data connection (even though it won't pass any packets or allow traffic). Then when we come back to T-Mobile data, it hasn't released from the roaming partner.
Does that make any sense? It was better for a few weeks, then picked back up again recently. I don't think it is a phone issue, because we have Wings, Dashes, and I've used an unlocked ATT 8525, with the same results. I know that when I used the 8525 with an ATT SIM, I didn't see this issue coming off of roam.
Thanks
nobody else has seen or heard of this problem?
I have the same problem with my HTC Tornado an WM6 with original WM5 image everything is fine
I have a T-Mobile HD2, but T-mobile doesnt workin at my workplace. AT&T works so I was wonderning if I could force a roam. I've tried to manually connect to the network, but network registration fails. Anybody know anything?
Roaming is for countries other than your home country... no operator that I know of lets you roam to their competitors' networks... (apart from operators that own no physical network and have agreements to use other carriers' networks, in which case you can benefit from all... but that's rare).
But...
That is exactly the case with T-Mobile and AT&T. I got to school in Denmark, SC in the country. There I can roam on AT&T cuz theres no T-Mobile tower. When I got home its back to T-Mobile. The only thing I could say is that the roaming could be region or area specific. Could that be the case?
I guess the best way to know is to call TMO and ask...
I roam on AT&T just fine up here (Mendocino County in Northwestern California) in dead spots, and that's in-market where there are also T-Mobile sites. We're a former Edge Wireless market (AT&T Affiliate, taken over by AT&T in April of 2008), and all former Edge Wireless markets have this, we get to use AT&T and T-Mobile's network, I can force (instead of letting it automatically roam over) it to roam on AT&T if I want as well.
force roaming hd2
i have just purchased a hd2 i would like to know nore on this subject since i do not reside in a area that offers descent cell service... i know it is possible on a g1 (my last phone) but would there ve a way to do this on a wm 6.5 fustom rom?? or another ahdroid on for that matter i know nothing has been discissed in some time now on this thread but any help/redirectoon would br much appeeciated.... thanks. ps. sorry i should enable spell check.
Hi
Starting on EE. I have had my phone (GTI9505) unlocked from a shop and also had a code. The phone is unlocked and works with EVERY other network sim besides Three.
Three shows under my APN settings but all i get is no service then emergency calls only.
this has been happening for about a month now and only once (last night) did it show the network 3 before gong back to emergency calls only
ive tried 3 different three sims (coincidence) none have worked and the same 3 sims work in other phones. Did i mention that all other networks work?
ive tried changing the network mode and pressing automatic search under network operators. when I go to manual all i see is EE, O2 and Vodafone
i rang three to see if they blocked it and they assured me it was not blocked
i am on android 4.4.2, i9505XXUFNC9
How can i enter the service menu so i can have a play around with the settings/radio etc?
anything else i can do/try/flash?
You've probably just got no signal in your area. Three are probably the worst service for coverage. I've had no signal indoors for the best part of a month. Customer services just fob you off with "they are carrying out work in the area", which is not shown on their website. Absolute joke of a network. Soon as my contract is up I'm going back to tesco/O2.
