Cingular Network Help for SX56

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.

Unlocking AT&T SX56 for use with Cingular

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.
Boone

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.

can i add network provider????

hi all
i just bought my t-mobile sx56
i unlocked it with the help of this great site

yes it has three bands

I had a old XDA1 to unlock for a friend, as i had seen the latest 2003 rom that unlocks the radio and gives him 2003 i used it, it worked fine but then the radio would not work on 1800, And as he was on orange here in the UK, i could not find a fix so i had to go back to 2002 rom and unolock it.

hi
thanks alot for the info
i am using 2002 and when i search for a network provider i only get
o2 and vodafone
is it got to do with virgin or t-mobile band
the bands in my mobile are
900
1900
900/1800
is that a problem

in the UK o2 and Voda use 900 Orange and T-Mibile (virgin) use 1800. you need the option 900/1800, rather then the 900/1900 you have, i will find the rom i used and the correct radio, cant remember that well but i am sure the model number (not on the sticker as this can be changed by changing the radio rom) it ends with a "A" or "B" and this denotes if its a 900/1900 or 900/1800 model
John

Try the bandswitch option in bootloader, hold power while pushing soft reset, then push the button below antenna, choose 900/1800 and see if that gives you the network you need, this may hard reset your phone so backup first.

[Q] Help! SGS not connecting to phone network

Hi all,
I recently bought a T-mobile SGS and live in Norway. the seller said it is unlocked and using *#7465625# confirms it, everything is off. However, it doesn`t connect to any of the service providers in my country. I`ve tried several different providers without any luck. with android 2.1 it said "your sim card does not allow a connection to the network" when I tried to connect manually. I installed 2.2 (Froyo) and now it just says "unable to connect to network". I have no idea what to do!
Do I have to change the product code? currently it is GT-I9000HKDTMU.
Will it help unbranding it?
Please help!

Make Sure your phone company has the same frequencies that the phone allows. I bought a T-mobile version first and brought it to Canada to use on Rogers but i found out that the frequency for the radio isn't compatible with Rogers service.
For your T-Mobile SGS your frequencies are as followed.
GSM850, GSM900, GSM1800, GSM1900, UMTS1700, UMTS1900, UMTS2100 / CSD, GPRS, EDGE, UMTS, HSDPA, HSUPA
If the phone carrier in your region doesn't use these frequencies then it wont work. Simple as that.

Question to those who have their S4 _successfully_ unlocked by Sprint

Did you received any sort of OTA when Sprint unlocked your phone?
Currently Sprint claims that they just mark the phone as unlocked in their DB and then you need to restart it.
It clearly doesn't work for many, the phone still shows "Invalid SIM" message and the consensus is that this is not normal and the phone is not unlocked.
So the question for those who have their phones _successfully_ unlocked, was there anything in addition to Sprint saying that they unlocked your phone?

You call them (or chat) and ask to unlock the phone to be used with 3rd party GSM carriers. That's what I meant.

tmobile is on different bandwidths when they say unlock they mean international not any us carriers and even if it did work you would only get edge no 3g or lte

no, tmobile and att bands are supported by the hardware.. but are blocked by samsung/sprint regardless of unlocked sim status. if we can unblock it 3G would also be supported. WCDMA band support on the Sprint GS4 includes 850mhz and 1900mhz... so that means 3G works just about everywhere for ATT... and Tmobile would have no AWS band support but would have 3G in areas where Tmobile has refarmed 1900mhz.
Again.. the hardware itself supports these bands... its just an extra block thats stopping us. I am working on the unblock for ATT/Tmobile.
And to the OP @obender, @jj14's post show exactly what Sprint sends when the device is unlocked. Other than that... go thru the steps and that's that. As jj14 also states.. he can pop in a tmo sim and gets no error... proving he is truly unlocked.

I had my phone unlocked, and I did the above as per the email I received. However it just said that the profile had been successfully updated, which was the same thing it said before it was supposedly unlocked when I pressed UICC unlock. It also didn't change to GSM mode automatically. So I wasn't really sure it had worked, but I was able to put in the AT&T SIM from my Nexus 7 and I didn't get an invalid SIM error.
When I went to Costa Rica, I was successfully able to use my phone with a prepaid SIM (GSM and HSPA/WCDMA). That said, I had to go into the Testing menu and force it to use only WCDMA, otherwise it would only use GSM/EDGE (even selecting WCDMA preferred didn't work... it would switch back to GSM pretty quickly). I also had to make a build.prop edit to be able to add an APN to use data. So you basically need root if you want to use data.

I just recently got my S4 from sprint I had them unlock it for international use all the available networks now show up, but in regards to invalid sim msg I will not know till the end of September when i am out of country. and on a side note if you call Sprint before you own the phone for less than 90 days you have to go through a lot of loops but they will unlock it for international use. out side of that I am unsure as too how far the unlock actually goes.
will keep you updated as to my findings I will be trying a different sim card while over there
