Guest iraqigeek Posted July 24, 2004 Report Share Posted July 24, 2004 Hi all A couple of friends and I have purchased three AT&T MPX200s. We have unlocked two phones and they accept the local provider SIM they can read contacts from the SIMs, save them back to the SIMs, and have a working AT&T sim card in the third phone (works on roaming in any other phone), but none of the phones are working. The local provider operates on the 900MHz band, we are sure of that since my other two friends work for the provider. I read on the internet that the MPX200 supports GSM900 by hardware, even the AT&T branded phones. We have treid flashing SIX different ROMs, fout SM2002, and the two versions of WM2003 from @nonymous, but without any success. We even conducted a test from the local provider exchange, in which one of my friends was trying to register the phones on the network, while the other was logging all requests in that cell, but there was no request received by the network. We tried using auto, 900/1800, 1900 on the preferred band in phone settings. Under settings->phone->networks, we tried using automatic and manual in network selection, tried find a new network, select a network, preferred networks. Each option was tested with all other options combinations but with no success. What are we doing wrong? is there any special setting that needs to be done? any patch that needs to be installed? Edit: On one of the phones, I can get the local provider once when flashing WM2003, doing a master reset, adding the local provider's code in preferred networks, and doing a network search. BUT it only happens with the AT&T SIM card, and only once after flashing and hard resetting. When I do a search again, I can't get any network. Even when I find the provider in the network search, still I can't get the phone to register in the network. Thanks, IraqiGeek Link to comment Share on other sites More sharing options...
Guest awarner [MVP] Posted July 24, 2004 Report Share Posted July 24, 2004 The AT&T phones are not 900 band enabled. For tri-band phones you need the Orange MPX200. Link to comment Share on other sites More sharing options...

Is there a way to enable the 900 band??? One guy told me his friend had an AT&T MPX200 and went to Yemen, which has only 900 coverage, and it was working there?!?! I know it has the hardware for the 900. There has to be some way to enable it. Link to comment Share on other sites More sharing options...
Guest awarner [MVP] Posted July 24, 2004 Report Share Posted July 24, 2004 There is not a way to enable the 900band on the AT&T phones as it's a hardware configuration. A few of the early AT&T phones did appear to have it working but there are not many around as this was more a supply error by motorola. Link to comment Share on other sites More sharing options...

Thanks for the replies :P Aren't the 900 and 1800 together in the hardware of the phone (same IC or something like that)? I know they are on all other triband phones I read about / worked with. And isn't the radio DSP embedded in the TI OMAP??? Link to comment Share on other sites More sharing options...
Guest awarner [MVP] Posted July 25, 2004 Report Share Posted July 25, 2004 Unfortunately not, the 900band has not been physically enabled :P Link to comment Share on other sites More sharing options...
Guest ShinyBill Posted July 27, 2004 Report Share Posted July 27, 2004 I have found that on my O2 UK MPx200 my 900 band has also disappeared. AFAIK O2 uses 900, but my phone still works fine set to Auto, so it is not a problem for me. But before I flashed, there was definitely a separate 900 option, which has now disappeared... Just letting you know in case it helps at all, though it probably won't :P Link to comment Share on other sites More sharing options...
Guest aliensix Posted July 29, 2004 Report Share Posted July 29, 2004 Mine's working alright. I bought my from the US, AT&T branded. 900GSM blocked. Its only after flashing it with generic roms and now to smartphone 2003 that I can do quite well with 900gsm in Australia. Full 4 bars of reception in the city area....sadly 2 bars in my suburb but certainly an improvement from the earlier times! :P Anyway the latest rom (aka supermoto2) released by @nonymous has allowed the 900 option again.

Cheers I have tried using both @nonymous roms, but still nothing :cry: I can't find any network. I have tried using auto, 900/1800, and even 1900.

Guest mweber Posted August 1, 2004 Report Share Posted August 1, 2004 IraqiGeek - You said you were using a provider that supported 900Mhz. Is this in the US, if so who is the network provider. I would like to use 900Mhz as well, but can't find a provider. Thanks, Mike Link to comment Share on other sites More sharing options...

I would like to use 900Mhz as well, but can't find a provider. Thanks, Mike I am in Iraq, not in the US. The local operator in Baghdad, Iraqna (a branch of Orascom telecom), operates on the 900MHz band, so does the northern and southern operators. The CPA/interm gov. gave license only for the 900MHz band. Link to comment Share on other sites More sharing options...
Guest hbk5585 Posted August 1, 2004 Report Share Posted August 1, 2004 I have a question. I have the WM2003 version and I have the band set to 900/1800. My question is: I am living in New York and have ATT, so which one should I be using, the 900/1800 or the 1900? I tried out both and don't see a real difference, but I use the 900/1800 band because I have heard it is the better band. Anyone have a comment or suggestion?

Guest awarner [MVP] Posted August 1, 2004 Report Share Posted August 1, 2004 The 2003 hacked reom does not enable or disable the 900 band. The reason being for this is because this rom was hacked from the AT&T 2003 rom image. There is no miracle 900 band enabling Link to comment Share on other sites More sharing options...
Guest aliensix Posted August 2, 2004 Report Share Posted August 2, 2004 Some say that the phones itself has the hardware support for 900GSM, some say its the same deal as 1800GSM, some say it wouldn't work at all. Well I guess it really depends on your luck though I hate to leave my life to chance except to God. Unless its more of a reception problem? The mpx200 isn't very good with reception in areas with poorer coverage and I have experienced that significantly before. My suburban area is proof of poor reception, sometimes not connecting to a network at all. :| Good luck anyway! Link to comment Share on other sites More sharing options...
Guest aliensix Posted August 2, 2004 Report Share Posted August 2, 2004 I's say its all there (900/1800/1900 GSM), the rom upgrades are just a part of labelling it. eg. Supermoto 1 labels it 1800 alone I think (kinda forgot), 1900 and Auto. Whereas supermoto2 labels it 900/1800 ,1900 and auto. Link to comment Share on other sites More sharing options...
Guest awarner [MVP] Posted August 2, 2004 Report Share Posted August 2, 2004 Unless the phone has it enabled is will not be possible to use the 900 band. It is a hardware configuration that AT&T d3cided not to use on their phones. Only a small ammount of AT&T phones that are tri-band are around the rest are dual-band Link to comment Share on other sites More sharing options...
Guest aliensix Posted August 3, 2004 Report Share Posted August 3, 2004 Well explained! I guess if you happened to get one that is hardware-enabled to support all 3 networks, blessed are you! I've to thank my lucky stars then! I could have gotten a useful brick which is only dual-band and that I cant use it here (in Australia). Link to comment Share on other sites More sharing options...
Guest tyro Posted August 3, 2004 Report Share Posted August 3, 2004 Would it be cost effective for motorola to produce several versions of the phone, and not just have a software setting to disable the 900? Is it confirmed that the US version of MPx200 by ATT doesn't support 900 band at all? Does anyone know of any 900 band providers in the US?

Guest cs_e Posted August 4, 2004 Report Share Posted August 4, 2004 Hello! I've got one AT&T mpx200 and the 900 MHz Network is defenitly NOT working! only the 1800Mhz Band works fine. only a problem because in my country 900 has a larger coverage!!! Is there no chance to get it enabled by a service center? What did AT&T disable? Or did they have other mpx200? thanxs Link to comment Share on other sites More sharing options...
