Cellular Phone Forum / General / GSM / February 2006Help with UNLOCKED Motorola A1000 on Cingular
Hi, I just got a used UNLOCKED Motorola A1000 today. Previous owner said it worked on Verizon and Tmobile, however when I put my cingular sim into it, the phone cannot register with the network. It "sees" the cingular network and actually lists that it is available, however, it does not register the phone. It says, I can only make emergency calls. I tried different Cingular sims and same problem. - When I boot up the phone, it recognizes my number, then it starts searching for the network, - In the phone settings: - I have it locked to 1900 MHz - In the "Avail" tab it sees the "Cingular 310-260" as the only available network - "Register" is the only selectiion I have - I select "Register" then it tries registering with the network, then it fails. Handset Information: Ram: 32MB Version: REL_51.95.00 Baseband: A1000_U_34.15.OBP Flex: USA 1000H3GAR341003 AP Config: A1000_generic_APCONFIG_014 I emailed the seller and he did say it was unlocked. He used Verizon and TMobile in Hawaii so it does work. Any suggestions? I'm live in Baton Rouge (zip 70809) and I do pick up 1900 MHz on the phone.

I can't believe that it worked on CDMA I'd suggest you try another non-Cingular SIM. Maybe you know someone who used T-Mobile. Did it show T-Mobile's network at all?  SignatureDonald R. Newcomb DRNewcomb (at) attglobal (dot) net Donald, I tried a TMobile chip tonight and it worked fine; I was able to make and recieve calls. It worked fine. I threw in an old AT&T chip (someone that got converted to Cingular now) and it has the same problem as the Cingular chip. Any insights Donald? This is driving me crazy. Tam >I tried a TMobile chip tonight and it worked fine; I was able to make >and recieve calls. It worked fine.

You'll need to get it unlocked to use it on Cingular.

Newcomb DRNewcomb (at) attglobal (dot) net Hi guys, My 64k cingular sim is good and valid and I called cingular and added the new phones IMEI to my account. I also asked them to make sure that my sim was worldwide roam capable (in case I go overseas) and they said that it was already activated. However, I still have the same problem......*sigh*... I'm going to ask for a new chip to make sure it scratch that variable from the mix... Tam > > Then it's probably locked to T-Mobile.

Not blacklisted but blocked for some other reason. It might just be incompatible with Cingular's net in BRLA. I ran into a similar problem many years ago with a Nokia 2190 on DigiPH PCS's Siemens-built network. I had to send the 2190 back to Nokia to be reflashed before it would work on DigiPH's system. This one is a puzzlement. I've searched HOFO but did not find anything like this problem. SignatureDonald R. Newcomb DRNewcomb (at) attglobal (dot) net Hi, I talked to a guy at Cingular here and we do have GSM 1900 coverage here in Baton Rouge. However, I still cannot register my sim to the network. I threw in an OLD Hutchinson (Orange in Hong Kong) sim card in and it immediately said, "Emergency Calls Only." However, the phone was able to find the T-Mobile network 310-260 when it was searching for possible networks. I will be travling through other cities in the coming weeks so, hopefully I can see if it's just the cingular network in the area and not the phone. Thanks for all the help..I'll keep you posted.

However, I still cannot register my sim to the >network. Another possibility:- Cingular in your locality are "hiding" the 1900 band. and only handing over from the 850 band? Some GSM networks operate this way, i.e. Tel$tra in Australia (GSM 900/1800) "hide" the 1800 band. I must admit though this would be unlikely in your case (as I have received Cingular on the 1900 band in LA area), but maybe worth checking. What happens when you take off the "only 1900" feature? Hi, I put the phone on "auto" to search for a network and it still comes up with "Cingular 310-260" which really is a T-Mobile gsm 1900. I try to "register" and it fails.

Worth checking, but if the phone is blacklisted by Cingular, then it would normally be blacklisted on T-Mobile as well, since blacklists are exchanged between carriers. SignatureBest regards, SEE THE FAQ FOR CINGULAR WIRELESS AT John Navas <http://en.wikibooks.org/wiki/Cingular_Wireless_FAQ> > I have it locked to 1900 MHz Either the phone is locked, or being restricted to 1900MHz is the issue? Not sure if this is the case, but my brother lives in Baton Rouge, an he uses cingular. He did mention that BR and most of LA uses the i mostly the 850 band. It could be possible that because of the phone' lack of 850, it's not able to get the signal. I know cingular i 850/1900 and tmobile is 1900 pretty much, but in that area where yo are the only available signal is probably 850 -- mrcamp > Not sure if this is the case, but my brother lives in Baton Rouge, and > he uses cingular.

Here in Australia we have 900/1800 for GSM, but 1800 is only in larger cities and the phone must first register on 900 before the network will hand you over to an 1800 base. Maybe your network may require you to log on to 850 first before you can be handed over to 1900. Worth considering? -- The views I present are that of my own and NOT of any organisation I may belong to. 73 de Simon, VK3XEM. >> Not sure if this is the case, but my brother lives in Baton Rouge, and >> he uses cingular.

OK, glad you could eliminate that possibility. -- The views I present are that of my own and NOT of any organisation I may belong to. 73 de Simon, VK3XEM Hi guys, I spent some time on Howardsforum.com today and I looked up this Cingular problem: Basically, I'm screwed. According to the posts, my Motorola A1000 is a Tri-Band phone withOUT gsm 850, which I'm basically sh*t out of luck. (http://www.howardforums.com/showthread.php?t=660124) The network that my phone was seeing says, "Cingular 310-260" actually is a gsm 1900 T-MOBILE network, and that Cingular blocks my ability to use that because Cingular's gsm 850 is ALSO available in my area, which of course I can't use because I don't have 850. Some of the posts I read said that you can only use 1900 if and only if 850 is not available (e.g. roaming). *sigh* Thanks for all the help, Tam The bottom line is: Using a phone without the 850 band in Cingular' network will not give you adequate coverage (if any) in most places You can get away with it in some places though. But, if you phone i 1900 ONLY, just go with tmobile, since they are mostly a 1900 ONL network. Even tmobile is beginning to sell phones with the 850 band and now allowing 850 roaming in some places -- mrcamp Hi, I'm in Fort Smith, Arkansas and it seems that the phone is WORKING (on network "Cingular 310-380"). So, you guys were right that Cingular in Baton Rouge has a problem with 1900 GSM and is causing problems for us folks without 850. Wirelessadvisor states that Cingular 1900 is available, so, do you think that they might be blocking or running the controls on 850? Tam > Hi, > [quoted text clipped - 7 lines] > > Tam Hey Tam, I'm sorry I can't answer that but can you tell me if you'll be using this phone in Japan during your travels? If so, could you please let us know how it works? I assume that the UMTS 2100 "should" let you work in Japan if you get a Vodaphone USIM, (I THINK). This is really important to me - sure appreciate you letting us know how your travels go in each country you visit. r/ Steve As I said, when my brother switched over to cingular GSM, the reps. tol him not to even think about getting a phone without 850 with Cingular. think that's just the bottom line: A phone without the 850 band will no give you very good coverage with cingular in most cities. phoennix10@gmail.com Wrote: > Hi, > [quoted text clipped - 7 lines] > > Ta -- mrcamp >As I said, when my brother switched over to cingular GSM, the reps. told >him not to even think about getting a phone without 850 with Cingular.

Here in California, 1900-only phones work pretty well. SignatureBest regards, SEE THE FAQ FOR CINGULAR WIRELESS AT John Navas <http://en.wikibooks.org/wiki/Cingular_Wireless_FAQ> Absolutely, John. I know about California and a few other cities. That' why I specifically mentioned "most cities" in my post. If any one wil be doing any kind of extensive travel around the country, it's best t have a phone with both bands.

Thanks for all the help guys, Tam > Hi, > [quoted text clipped - 7 lines] > > Tam Perhaps Cingular holds a 1900 MHz license, but hasn't needed the additional capacity yet (hasn't built a PCS network).
