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
Hi, folks.
I just got an AT&T SX56 and I'd like to be able to use it with my Cingular account. I cooked a 3.17 ROM from yorch.net and the rom took, but when I try to use the phone functionality, it prompts me to turn on the wireless radio, and then enter my SID. I called Cingular customer service and got the SID for my area (00035), but it claims that the entry is invalid. I have heard that there could be problems with the radio stack when moving from AT&T to Cingular, but I'm not really clear on what that is, even whether it is a hardware or software thing.
Any help would be greatly appreciated
hi,
I didn't get you, did u upgrade successfully to 3.17 ? ... if yes, then it shouldn't ask you fot the SID code (try 8 zero's tho).
If the the upgrade failed then try the SD card method.
try to give more details.
Thanks for the reply, Biso007.
I think the xdaunlock program did the trick. I thought that the act of loading a new ROM would unlock the phone, but it didn't unlock until I used the xdaunlock flie.
My phone seems to function normally now.

Hi I just recently purchased a SX-56 and would like to use it on Cingular. I ran the unlock program and it tells me that there is no SID lock. When I put in my SIM Card the phone program picks up my number, but I can't seem to connect to the network. Any advice?
hi, i actually work for AWE and have an SX56. I'm sorry to be the bearer of bad news, but this device will not work on Cingular's network. Cingular runs mostly 850 band gsm and this device only does 1800, 900, and 1900. it theoreticly will work on there roaming partners towers that are 1900 band, but that is only if it is unlocked and the 1900 band is less than have of there coverage. Hope this info helps.
Phil
Okay, so my only hope is roaming on 1900. Is there a particular Radio File I should be using (ie. T-Mobile or AT&T) to pick up the towers I can roam on Cingular with?
I am not sure, As far as I know, the phone just needs to be unlocked and it should pickup the 1900 band automaticly regardless of what sim is in it.
I have a Cingular Sim card, and Cingular service on my XDA II, I live in the United States (Massachusetts). It always connects to AT&T Wireless's towers because AT&T Wireless is now part of Cingular, I want to get on Cingulars towers, any ideas people?
you could set the Network Selection to Manual instead of Automatic and choose cingular......... and also set the Prefered Networks only yo cingular....
hope this help
nope, when i do manual selection i only get t-mobile and at&t wireless. =/
well it means there isn't any cingular towers near you!
there are towers next to me, it just picks up at&t wireless, not cingular.. cingular is set in the Set Networks though, but when I try to manual connect, only AT&T Wireless comes up...
Have had my wizard for a couple of weeks now, when I bought it, it had the O2 software running on it, its branded externally as an O2. I upgraded the ROM last night but i have noticed that the phone (as before) still thinks it is using the T-mobile network e.g. when i tap on the signal strength indicator or a message comes through, it indicates the t-mobile network. I can receive and make calls as well as text messages and voicemail on the virgin network no problem. After doing the rom update last night i indicated that i was on the Virgin network when prompted when the device was initialising.
So how do i get rid of the fact that my wizard thinks its using the t-mobile network when its actually using the Virgin network. The phone is branded externally as O2? How on earth did this t-mobile identity survive the ROM update. Note i applied the I-mate ROM.
During the ROM update i left the sd card containing the previous ROM image (O2), a backup in case things went wrong, in the device. I noticed that a little after i ran the imate rom update from my host pc a message appeared on my imate mentioning something about the fact that there was an SD card containing a rom image and if i wanted to use this. It was very late and by the time it registed with me what i was looking at the message timed out and the rom update continued. Could this explain the reocurrence of the t-mobile wording. When i reset the device the imate splash is what i see.
Currently:
ROM version 2.16.9.1 WWE
ROM date 2/6/06 (6/2/06 here in the UK)
Radio version 02.07.10
Protocol version 413.1.03
ExtROM version 2.16.9.101
Thanks for any help

Virgin is a virtual mobile operator and uses T-mobile's network. Its common for T-Mobile to show up as the carrier on many mobile phones.
Roaming indication after upgrade
Hi have the same problem.
I have a T-mobile (US) phone; I upgraded the ROM (Qtek test ROM) and since then, the phone shows that I am roaming into Cingular network.
In my area (San Francisco) - Cingular is the actual network operator; T-mobile uses Cingular's infrastructure as part of a deal made long time ago.
So, the ROM is correct but I wish there was a way to disable the ugly triangle (showing that I'm roaming) or alternatively - let the phone know that I'm parked in a "home-network".
Ah thank you for clearing that up. By the way is it true that virgin has been bought by NTL, someone mentioned this today. Not sure who is worse NTL or Virgin UK.
Do you know where i can get the settings for MMS and GPRS, have not checked if they have been set up properly.
Many Thanks
Fergus

it's true...
The operator logo in the dialer does not automatically change when you switch networks / sim cards.
It depends on the image file 'carrierlogo.gif' in the Windows folder.
I have an unlocked T-Mobile MDA Vario with an Orange sim card - this showed as T-Mobile until I updated the carrierlogo.gif file!
If you want to view the network you are currently connected to, go to Start | Settings | Phone | Network.

Have you tried another QTek ROM? Otherwise, it's a possible SIM-related issue. The SIM hasn't received an OTA (Over the Air) update telling it that it is connected to T-Mobile's local switch. Furthermore, you shouldn't be on the shared network anymore since the old GSM 1900 shared network was sold to T-Mobile in CA and NV as part of the Cingular/AT&T merger. I would think that T-Mobile has updated that GSM 1900-only network to broadcast only their MNC (Network Code) so any T-Mobile SIMs registered on the network know that it is a native network.
I purchase MDA from TMO, unlock, upgrade ROM to 2.4. But in my office when I have TMO sim in, I don't have signal. I then switch out to cingular SIM and I have signal 2 bars. I then put TMO sim back and try to do manual signal. when TMO and cingular show up i select it but somehow the phone switch back to TMO network again then signal will be lost. Any idea why???
I'm in S. california ZIP 91767
both test done at the same location
I'm not sure you have described your problem too well, if your using a SIM from 2 different service providers why would you expect both signals to be the same? From the description of your problem it sounds as if your in an area where there is little or no T-Mobile service but some cingular service. If this is not what the problem is can you please have another go at explaining what is wrong. :?:
well, I'm under assumption that TMO has roaming agreement with cingular. so if my MDA can't lock on TMO tower, it should try to lock to cingular, right??
Your theory is sound but I have never heard of such an agreement nor have I seen my phone ever display the Cingular logo. I didn't think the roaming thing worked while you were in your home country. Maybe the roaming agreement only covers those states were T-mobile has zero coverage rather than poor or patchy coverage. I'm in SoCal as well so I should get a similar service as you. I would be interested in any info you can dig up on this...
