AboutDebiN Expertise I can answer questions on cellular phones, the physical device, the network, what to look for when purchasing cell phones. I am located in the United States. I am an expert on BlackBerrys, Treos, HTC devices and iPhones as well as cellphones and aircards. I have over 15 years of experience in both the wireless and wireline world with the carriers. I have a lot of knowledge regarding the wireless providers - their services, prices and policies, both GSM (AT&T (formerly Cingular) and T-Mobile) and CDMA (Verizon, Sprint/Nextel (iDEN)). I am very familiar with the individual devices and their specifications. I can also answer questions regarding BlackBerrys, iPhones and other PDAs, both Palm-based and Windows-based. I can troubleshoot most any problem someone is having with their cellular device or with the provider.
Experience Over 15 years in the telecommunications field in the United States.
I have a cingular account. However I have a 7230 blackberry T-mobile/cingular phone. I out my cingular sim card in the phone and all it will do is show my phone number. The phone keeps saying no coverage or no service. I put my sim card in other phones and I have perfect signal.
I bought the phone off of a person on ebay and he said that the t-mobile phone would work with a cingular sim card.
So Debin what do u think the problem is?
Thanks,

Answer Hi Chad -
The device you purchased is a tri-band device with only one US band (1900 MHz). Since I am assuming it is SIM-unlocked, it should recognize the AT&T network when you put the AT&T SIM card into it, however, because it is missing the 850MHz band, there is a good possibility that where you live, the 850 band is being used and this device will not work for you. In order to have your SIM card work on the AT&T network, you have to have a device that works on both the 1900 and 850 bands in the US. This device was designed for only the 1900 band in the US for T-Mobile. It is not a device that will work properly with AT&T (which is the same as Cingular). My advice is to return this device, if possible. It is a T-Mobile only device, very old and not worth whatever you paid for it. If you want a Blackberry to work with the AT&T network, I would suggest that you buy an AT&T branded Blackberry, i.e,, 7290, 7100, 8700, 8300, 8310, 8320, 8800, 8820, 8100, 8110, 8120, but not anything else. I hope this helps and please let me know if you need any additional information. Thanks. DebiN
