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.

handbook?

Hi Folks
Does anyone have a soft copy of the handbook for the Universal they could post or mail me? Love to have a read.
Also, for the 3G calling, does it use a sim or usim?

3G traffic (be it data or video) always require a USIM. If you don't have any, you cannot get onto the 3G network. I'm actually having this issue, as I travel to the UK a lot, where T-mobile has a live 3G network. As I do not have a USIM (since T-Mobile NL doesn't offer 3G yet), I cannot roam onto their 3G network, only onto GPRS...
Bugger...

My operator (Telenor in Norway) enables the customers to use their OLD SIM cards and still have full 3G access!
My SIM card is from 2004, but customers may use cards that go back to July 2000 on the 3G network..
There has been some Over The Air updates, but these might be for something else..
The user only gets a SMS saying: "You SIM card has been updated, please reboot your phone."
So we can use the same SIM on a new and old phone, 3G or no 3G...

Not 100% what you're after, but hope that helps.

Well, I'm using a 4-year-old T-Mobile SIM in my JasJar, and I'm getting 3G access with absolutely no problems...
I didn't think there was such a thing as a USIM exactly? I got the impression that a "USIM" was just a normal 3v SIM card which has been enabled for use on the UMTS network. And that's done by pressing a button at T-Mobile 'Command Centre'...
'3' here in the UK make a big deal about USIM cards, and how you have to have one to use a 3G phone, but that only seems to apply to their handsets, because they put about 800 billion security locks on each of them. In my experience, Vodafone and T-Mobile don't require you to upgrade the actual SIM card at all, and I assume that Orange and O2 are the same.

Hmmm, you learn something new every day... It could be that one can indeed update the SIM to a USIM with a OTA update, I just hadn't heard about that before. I might put in a phonecall to T-Mobile...
Thanks for the heads-up!

I'd better just point out that my last post was entirely guesswork on my part, based on the fact that my old T-Mobile SIM, and my sister's (3-year?)old Vodafone SIM both work perfectly in 3G devices.
In my case, I never even told T-Mobile that I'd bought a 3G phone, the SIM just worked on 3G from the second I put it in, so no OTA upgrade needed? (Of course, maybe they gave us UK customer's an upgrade one night without telling us?!)
My sister got an official Vodafone upgrade to a 3G phone, so they may have done an OTA thingy at the time, but the actual physical card is the same...

3G + Universal + Australia

Hi,
Could those Universal owners in Australia response to this thread with...
a) What provider they are with
b) What plan they are on
c) The procedure for configuring their unit with their provider (to this point of surfing the net on mobile broadband.
Rather than trial and error I thought I'd try and cheat and just ask someone who's gone through all the pain already.
I would also be interested to hear comparisons between plans and providers.
Regards
Michael

I'm interested too! I've been looking on the net at Telstra, Optus, Vodafone and Three but I can't see anything really great - all very exy!!
Most are linked with phones on plans - not good for us we've already got the unit.
I want a sim only plan that gives me reasonable rates for data download.

I'm using Three - gave the bundled phone to a friend who wanted to upgrade an old NEC. $99 Cap Plan includes $15 towards data usage, but i've never managed to get past the $99 cap yet.
The data speed is fast - to get 3G you need to create a new connection, set the AccessPoint, which is "3netaccess", and leave all others blank. Roams to Telstra GPRS when out of coverage in Oz.
Don't bother with Three if you go overseas - there's no data coverage outside Australia for Australian customers.
There is also no comprehensible FAQ on their site for the MMS setup - just lots of pages with "your phone comes preconfigured - don't change it" comments. Ringing support is no good, if you try to, they soon figure out you are not using "their" phone, and can't help you.
If anyone else here has MMS working please give the settings.

Telstra Universal on 3G
I purchased my JasJar in the UK on a business trip, and with my UK Vodafone SIM had 3G working fine.
For Telstra 3G you need a new USIM for 3G - they should supply for free if you're a post-paid customer.
It actually roams onto the joing 3/Telstra network and drops back to Telstra GPRS.
The Telstra settings are simple - telstra.internet for the APN
Also, the 3G data plans are more generous - I changed from $55/month 5MB plan to a 3G $15/month 6MB plan.
All seems to be working fine.

I have the JJ and use Telstra. The process was simple, Tell my secretary to give it to me, TElstra call me back and say that I have it, use the Imate auto configure to install it and of I go.
Expensive yes, but in the overall scheme of my business costs, its not worth looking at. Telstra I believe have a special for the video call bit that they charge the same for a video call as they do for a mobile phone call, to get you to join and try it. I dont have anybody interested in video calls.
I didnt need a telstra sim to do this, and havent actually tested it for videos.
I only really use it a little bit for internet connectivity, and given that I have wireless networks at home and office, I dont use the GPRS to 3G connectivity much.
Heads up though and it is posted in these forums elsewhere that phone companies (and I suspect telstra) would limit it your speeds to the minimum required for video conferencing which is 128kb ps, whereas 3G networks are capable of 384kbps, and only switch it on when you ask for it.
I really dont have that much need, and it doesnt even come close to the capabilities and speeds, ease, costs and overall benefits of the ADSL wireless network.

Hi, I sold my Universal (O2 Xda Exec unlocked) to somebody on eBay who lives in Melbourne, Australia.
Today I received this e-mail from him after he received it:
"My sim card doesn't work."invalid or missing sim card" appears.Can you help me to figure out."
Any ideas anyone?
PS: I should add that mine was one of the 1st Execs shipped in December and was definately unlocked as I had it working with O2 and Orange. All I have changed is to install the new Extended ROM update from their web site, which I presume doesn't have SIM locking does it?
PPS: Update from user: "Thanks for your response.Australia has got a couple network. I currently use $49 cap plan Optus network. but I don't have any idea about frequency."

my friend had a problem with optusnet, told it was the phone!!
I put my telstra sim in, worked perfectly the first time.
went to optus, requested a new sim, got it tested it didn't work, logged a support call, waited for call back, tried agin with support, nothing returned, got a telstra sim the next day and never looked back...
moral, optusnet support sucks when they don't sell you a phone, the knoledge is limited and competency sucks.
BUT I do use them for adsl, and home phone, even then acknowledge that they suck.
Tell your customer to test it on a friends telstra card and run the telstra cab, its something in optusnet.
by the way, my friends phone wa the imate jam / xda mini so the problems hadn't even started with the 3g network of the exec.
my jasjar works perfectly on telstra.
pm me, or get your customer onto the forum if I can provide localised help.

Thanks. Can you please clarify what you mean by "run the telstra cab, its something in optusnet"? What is a 'cab'?
Are they the same network and would he be able to retain his account, or does he have to switch networks?

Networks in Australia
Although Optus and Vodafone in Australia actually share a 3G network (3G air interface) everything beyond that is separate so for billing etc your friend would need a new SIM card. It's likely thet Optus people did not sell him a 3G SIM card - they will have to tell them what it is for so they give him the right SIM.
In OZ, Telstra share with 3 so you 'roam' onto the 3 network for 3G even though you have a Telstra SIM

the cab file is located on the extended rom, or on the 02 website, or the imate website, I have also posted the file elsewhere on this forum if you look for telstra.
if you cant find it, i can locate it and post it, just dont have it handy now.
a cab file installs programs or settings to a device. this particular one sets up all the mms, phone and 3 g settings. if he did a hard reset, the phone itself would ask him his communications provider and do this automatically. but telstra can only be used on telstra, and optus on optus networks, and they are effectively strings of commands to access gprs, 3g, and wap sites.
he may not have run the setup correctly on this. if he installs total commander, and types into the address field \extended_rom\ he would be able to locate the file on the device already and just run it to establish his correct settings.
however, i feel it is likely that the sim card is dud.

Hi all, thanks for your previous help. The customer now has a new SIM from Optus, Australia, which works great for calls.
However, he cannot set up GPRS. He states:
"I tried everything to set up gprs setting.I couldn't.I check the my friend's xda ii series gprs setting.It has got auto config option.So it does itself.But my xda exec ask me phone number ,domain name,username password,dns setting etc.
I rang to Optus technical support.They told me they don't support this one.They gave me dns number but didn't work. But I think . if xda ii works, exec should work.I just need set up for Australia. Please help me."
Does anyone have a link to an Optus Australia auto-config util that will send him the config in a magic SMS?
Failing that, can you type all the details here or provide a link to the Optus cab?

I'm with Vodafone on a $79 cap. The cap value includes data ($1/5min), but the billing by time rather than downloads might not suit most people.
As for configuring the phone - I just downloaded the operator settings CAB file from clubimate.com. Sets up everything perfectly!
AFIK, Vodafone and Optus are the only ones that will offer Sim-only 3G plans. Of course, you can go with Three, and just discard the phone (you can get a free phone on a $29 cap!)

telstra also offer 3g plans, but I use their phone network and sim card as part of our corporate plan.
I have sent the customer the std cab file on my imate rom, which he reports was not beneficial for him.
I am not on optus so don't actually have the configuration settings.

i never tried data, but videocalls worked fine...the only limitation being it only works on the overseas 3 network (3 - Hong Kong in my case, this was 2 years ago when i still lived in brisbane)

It's okay guys, Optus were giving him wrong details. He found the right ones -- they're all over Google

BlackBerry change to Hermes - AT&T

We stayed China and Hong Kong mostly and 2 of my friends came from Chicago who were using the BlackBerry from Cig/ATT. they both buy a Hermes in Hong Kong and had different situation -
The first one just inserted the SIM card and after the network wizard run, everything going ok. (Scap 4.31 rom)
The other one inserted the SIM and after running the network wizard, once connecting to the network no matter Media or My ISP, it will cut off the connection and asked for setting (modem disconnect....)
I had tried this phone with my China SIM and working ok, I had tried to change the rom from Scap 4.31 to AT&T official, the same, tried the network setting with proxy/no proxy - same, tried theGPRS setting between PAP/CHAP - same (as i found the official AT&T rom with CHAP setting at default)
the phone with call functional ok, only cannot access internet, is anything lock the sim with the BlackBerry and cannot use other handset? I found some information from the bb manual saying that "register you handheld manually" so is this related?
thanks

Qtek 9100 not working on Florida T-mobile network

Hi all,
I hope this argument has not been already discussed. Because all the keyword related to this specific problem are very general, I'm having an hard time searching for related posts...
I have a Qtek 9100 (not branded and never locked to any company) that I used successfully with all the Italian mobile companies. I moved to Florida couple of month ago, and my Vodafone SIM has been working fine in roaming.
Because roaming is not cheap at all , I just bought a t-mobile SIM card. But when I insert it the phone says "Waiting for connection" forever. If I try to select the network manually, the only available one is "cingular".
I also bought an At&T SIM, that according to AT&T and T-Mobile customer services, should have exactly the same technology for GSM connection, and so my phone should work either on both or none...). Strange enough, it works perfectly with the At&T.
However, I would like to use T-Mobile, as it is much cheaper for the type of service I need.
Can anyone help me? Do you think it can be related to the GSM firmware?
Thanks
Giacomo

Did you try flashing a stock t-mobile ROM to it?
