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!

Does anyone have any further information on whether a special 3G SIM card is necessary to use the HTC Universal? If this is true, it is terrible news for people who'd like to use it in the USA.
Does anyone have an email address for a decision maker for one of the US carriers (T-Mobile USA, preferably)? Maybe if we send some rational emails, they will decide to pick it up.
It will be necessary to get a new simcard to work on a 3G network... though the Universal will work with any sim card without the benefits of a 3G network (i.e. if you put a 2.5G sim in you will be able to use GPRS in it etc)
I have an Xda Exec on evaluation. I can confirm it works with SIM as well as USIM, without issue.

Pls tell us more...about USB Host fuctionalities etc... battery life...Wi Fi..Bluetooth.Can we listen songs over Bluetooth Headset...?
Any issues related to twisting and turning of screen...Pls
If your carrier offers a 3G network you can get a USIM for no money - or the cost of the SIM so you can access the UMTS network.
SIM - lets you access a GSM network (or an iDEN network)
USIM - lets you access a GSM and a UMTS network
RUIM - lets you access a CDMA network - in theory GSM networks too for roaming (mentioning this for brownie points lol )
Hey guys,
I'm using AT&T Service on my HTC HD2 w/ Android. Everything's great except for the lack of 3G (since the bands AT&T use are different from T-Mobile).
So I was thinking, what if there was a way to roam onto T-Mobile's 3G bands?
But the thing is, I go to the Network Operators list and I only see AT&T. But I know there is T-Mobile service here because my relatives have T-Mobile and do get service here.
Here's a screenshot of the Network Operators screen:
Any ideas?
Not a huge deal as I am near Wi-Fi most of the time, but it would be nice to be able to use 3G
Mysimplemobile.com
Get a sim card.
Sent from my HTC HD2 using XDA App
I don't want to switch providers. I'm more than happy with AT&T's voice service.
Set your phone to MANUAL NETWORK SEARCH, then scan. T-Mobile should then show up in the list but you won't be able to access the TMO network with your AT&T card.
T-Mobile and AT&T do not have roaming agreements. You will need a T-Mobile SIM to access T-Mobile's network.
I'm on AT&T and just bought an unlocked LG V20 H990N (Hong Kong version). I took the phone to AT&T to get a new SIM card and have it set up, but it wouldn't connect to mobile data. The people at the store told me to call customer service since the phone is considered "jailbroken," and they couldn't get it to connect. Customer service referred me to tech support. Tech support told me the phone isn't being recognized by AT&T's network. The phone is being recognized as a 2G phone, which obviously isn't the case. They submitted a request to provision the phone to their network, which could take up to two week. They said I should have 4G access as soon as it's complete. Has this happened to anyone?
From everything I've read online, the phone should have no trouble working. People use it on AT&T just fine so I don't know why this is happening. I can make and receive calls. It says "3G" at the top, but I can't connect to mobile data. I can use it on WI-Fi only. I'm not a tech savvy person. I was hoping to get some insight here. Any information would be helpful.
This phone (hong kong version) has several data networks like GPRS, EDGE, TD-SCDMA, UMTS, HSDPA, HSUPA, HSPA+, TD-LTE, LTE, LTE-A
Theoretically it should work.
Ask someone at the AT&T store to check if the sim card is OK

If the SIM card isn't OK, would I be able to make calls and text like I can now?
Someone mentioned that the phone isn't working because I didn't use my old SIM card. Should this even matter?
I went back to AT&T. They tried different APN configurations and eventually got it to connect to mobile data.
But it's only a 3G connection. How do people get 4G LTE with this phone in the U.S.? This is so frustrating.
Using the Taiwan version H990ds, no issues. 4G LTE on bands 2, 4 and 17. H990N should support the same bands so you should get LTE.
Brother,
Can you advise where you find the root procedures or how you root the V20H990N (Hong Kong Version)? It is because I also has one but I don't know how to root this phone.
