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.

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.
Buddy switching to ATT giving me his Alltel branded PPC6800 if I flash the dcd rom, 3.35 radio rom and vzw carrier cab should it work on verizon? Are there any other hurdles I might encounter?
Thanks,

i doubt you will get verizon to activate it since it isnt one of there esn's, thats one thing i like about alltel they will try and activate any esn you give them they dont care where it came from
Thought I would update for everyone: I got an Alltel PPC 6800 on VZW. Here's how:
1) Logged into VZW My Business Account
2) Account Maintenance
3) Step 1: Enter cellphone number, click search
4) Action: Activate Equipment
5) Enter HEX ESN from Alltel phone
6) Ran through http://ppc.stoleyour.net/xv6800/ instructions to update radio, rom and carrier cab (thanks to Lord Cruik Shank nice howto)
7) Ran through http://forum.ppcgeeks.com/showthread.php?t=20090 Steps 5 - 7 to load the DMU Key with QPST (thanks to drellisdee)
8) ##778 Edit Security HDR Password to HEX ESN
Everything seems to be working I haven't tested the speed but EV stays on the screen. I also haven't test GPS yet. Will report back later.
Wow that is crazy......I can not wait to hear more...I had no idea that was possible....I did not realize alltel used GSM I thought they were CDMA. Does that phone have a sim card?
Ahhh.
Major USA CDMA Providers: Sprint, VZW, Alltel, Cricket that i can think of.
Major USA GSM Providers: T-Mobile, ATT ahhhh not sure
Not to mention VZW just purchased Alltel last month. But really you could can use any CDMA Titan (6800) on any CDMA carrier, if you can get the ESN on the network, and the right programming.
CDMA is more popular in the USA because the coverage area is better than GSM. Although I wish it was the opposite way around. GSM providers are alot more open on the device side.

Does anyone know if an unlocked 8525 will work on Verizons network? I've been using it on Alltel and Verizon bought them out now they want me to get a new phone. Sure hate to give this one up.
If the sim unlock has been run the there should be no reason why not...
Mind you I'm in Australia...
Cheers...
CDMA vs GSM
I went back and forth on this one. (and Welcome!!!!!)
Verizon here in the states is a CDMA (EVDO) system that doesn't use sim cards, GSM systems does. This relates to how your phone communicates on the network. Now willl a GSM phone work on a CDMA network, i think that it will. The SIM card in GSM phones supply the network with your PIM to access the network, it is tied entirely to the network not the phone. CDMA requires action from the carrier, and your access to the network is tied to phone not the network. You deactivate one phone first, then activate the second. You'll probably need to supply your IMEI to verizon and they'll load your access. Just a guess though, cause I've been with cingular/at&t since i carried around backpack sized mobile phones.
Does anyone know better?
As far as I know of, no. I don't believe it has a radio for the CDMA. Although you state you have used it on Alltel which I thought was CDMA...
What reason did they give for wanting you to get a new phone?
I was at at&t and we where unable to activate the phone even though the phone is capable. At&t said everything was good on there end but the phone just wont get a signal but it says it is on at&t.
Does anybody have any ideas how to fix this?
Have u unlocked the sim slot on the phone?

Quite a few people (including myself) on various boards have acknowledged having this problem as well. I got the SIM unlock code from Verizon but when I do a GSM network scan, nothing is detected. I know it has been escalated above level 2 support at Motorola and hopefully they will address it shortly. Here's another thread about it over on droidforums: http://www.droidforums.net/forum/droid-2-global/96596-droid-2-global-unlock-foreign-sim.html
Yes, I have unlocked the phone from the code verizon gave me.
I hope its a fixable problem. But I noticed when I use an active tmob sim the phone doesnt even say tmobile. But when I use an at&t sim it atleasts says at&t.
I'm very interested (as I'm sure many others are) in a resolution to this. OP did you call VZW global support and let them know you're having this problem? Hopefully the more they hear about it, the faster they'll have a fix

They where no help at all they said it was for foreign sim cards only and that at&t and tmobile where not supported. But they did say verizon was better than both of them combined.
If you feel like experimenting try this:
Go to dialpad, and enter *#*#4636#*#*
Click on Phone Information, and then scroll down to bottom. Set preferred network type from "CDMA auto(PRL)" to "WCDMA preferred" and see if that kicks it on ATT.
I'm 99.9% sure after looking through the user guide that VZW has restricted use of the 850/1900 MHz GSM/UMTS bands, even though the device has the hardware to support them. Most foreign networks use 900/1800 GSM and 2100 UMTS but AT&T/T-Mobile use 850/1900, which is why no one has had any success with them yet.
Hopefully someone can figure out a workaround.
EDIT: Just a US GSM restriction...looks like 850/1900 work abroad: http://www.droidforums.net/forum/dr...d2-global-south-america-first-impression.html

These where the results I got, so clearly it is getting seeing the network. Just not connecting.
Just got off the phone with Motorola and they said the droid 2 global was only for verizon sim cards and when I told them about the unlock code the guy didn't know what they where for. So another dead end. Another theory I have is that the stock verizon rom is blocking at&t so maybe if someone can flash another rom we can see if this is the problem.
Further proof the 850/1900 bands are locked: https://motorola-global-portal.custhelp.com/app/answers/detail/a_id/57058/p/30,6720,7706
"GSM-based global services work only with a SIM card supplied by Verizon Wireless® or by another GSM 900 or GSM 1800 service provider. When you set your phone to use a GSM 900 or GSM 1800 network you may be prompted to enter a subsidy code. To get this code, contact Verizon Wireless."
EDIT: Looks like they're just locked in the US, not abroad: http://www.droidforums.net/forum/dr...d2-global-south-america-first-impression.html

If this is true why would they say it has the 850 and 1900 bands? I know its not a hardware problem, so if its a software problem there is a chance we can have a workaround. Or the locked bands might be because of the verizon rom.
I was able to put a new rom on my Droid 2 Global and although the rom was working since it was for a droid 2 the radio was not working properly. I was not able to force turn it on. I still have several more things I will try tonight.

Keep us posted!
This has been done before on Windows Mobile phones (CDMA HTC Touch Pro 2) and requires a radio reflash since the bands are locked in the radio firmware. I am hoping they will develop a solution for Android phones. http://rhodiumw.htc-unlocks.com/
Being that this the 1st CDMA/GSM (Tie if you count Droid Pro) Android device I would wait and see.

Good info, thanks
As from what I learned from previous devices the Droid 2 Global Verizon has a security locked radio. I have seen people unlock the radios from windows mobile phones, it is as easy as installing a .zip file that will unlock the security. I believe it is the same way with the Droid 2 Global. I will try to get this working but I don’t have much knowledge in the development field. But I do know you will have to be rooted. I have also spoke with a friend at Verizon, which claims that they did indeed lock the radios and there is a workaround. He said he was not familiar with this workaround but said it was close to the problem with the windows mobile security locked devices. I am calling this the official reason the phone wont work with US networks. This makes sense, and now that we found the problem it shouldn’t be long before we find a way around it.
Thanks for the info swangotp...that definitely sounds promising. Keep us posted!
subscribing to this thread... I know this is possible.
I got my SM-G900P phone Internationally and Domestically unlocked, and while I can get voice to work on a T-mobile sim, I am unable to get data to work.
I'm currently on the stock Sprint 5.0 rom, I have also rooted the device.
I have also added the T-mobile APN, and have the network set to T-mobile, but still no luck
I'm not sure what I should do to get the mobile data to work.
Wondering if I flash a T-mobile rom, would that brick the phone? And would that unlock the bands?
Any and all help or suggestions would be greatly appreciated
Thank you
bump for some help
I know Sprint operates on CDMA while T-Mobile uses GSM technology.
I don't know if the G900P has the hardware capabilities to operate on GSM LTE bands. But it is interesting that you got the voice to work!
Try this page. He had a Verizon (CDMA) phone and got it to work on the AT&T (GSM) network. So apparently it is possible, and your situation is similar in trying to use a cdma phone on a gsm network.

Thanks for the link!
I already had tried what he did previously, adding the APN, sadly that didn't work for me . And once I had unlocked the phone I enabled GSF and got the voice to work. But sadly that's the farthest I've gotten
