Bought the Samsung SGH-D528, triband, gsm, from overseas in Shanghai. Unable to use with AT&T SIM card.?
Ok, I recently bought this phone from overseas in Shanghai, China. I just came back today and found out that even when i switched the SIM cards to the AT&T one, which was formerly a Cingular card, it kept on searching for networks but couldn't find any. Strange, I thought that the phone should work, since it is GSM, and it is unlocked.
Basically, knowing that this phone was gsm and triband, I bought it from Shanghai. I just came back to the states today, and I inserted a Cingular wireless SIM card, or at least now AT&T. For the entire time, it says it cannot find the network, while I tried re-inserting the chip to my old phone, it works fine. The question is, why can't the network be found? The phone is unlocked, and used with a Chinese SIM card earlier, but shouldn't be of any problem to the SIM card usage here right?
