The phone itself is very nice very very nice but....IF you are a cingular customer with another motorolla phone don't fool yourself into thinking you can just put in your sim card and be off....NO NO I tired this and unless there is some secret society that runs around giving out Subsidy codes then you can't use the phone. Cingular will tell you that they can reasearch the IMEI numbers to try key word try and get you a unlock code for the phone but then the phone is not covered under cingular warrenty and some of cingular features you are use to might not work. Call AT&T for the code since they are the only next option for this phone made for cingular and them well they too can not give you the code if your not a customer for their company and Motorolla themselves well they will tell you they can't get the number either cause it's done by the company the phone was made for and they don't have access to that kind of code. SO now again nice phone would be even better if you could use it with your SIM card if you choose. SO advice don't buy unless you are a AT&T customer or you are getting a SIM card with it.
