The best feature of this phone is that the voice quality(that you the phone owner hears) is excellent. It is so clear that my 85 year old mother who has extremely poor hearing can hear the caller well when it is in speaker mode. In contrast, she hears much less using a conventional phone with a boost mode or than when using 2 other nokia models on speaker mode.Downside is that in sunlight you can't see what is on the screen at all.The ringtone is not loud enough to be heard when it is in my purse. I have it on the highest setting and I am not hearing impaired. Never had this problem before with a cell phone.The users manual is written very poorly as opposed to the manuals I have had for Ericssons and Nokias. Also, the menu items are not always self explanatory so some features of the phone are not easily figured out intuitively.I bought this phone unlocked so that I could use my att SIM card here and foreign SIM cards abroad without having to pay high international rates. This Triband works 800-850/900/1900. Doesn't work with 1800. Also with the unlocked phone we could stay with our original ATT service contract which is far cheaper than current Cingular plans. In three months, I have recouped the price of the phone with differential in plans.
