You need to Unlock the Phone to use the AT&T Sim card..what is Mobile Phone brand and model..You can unlock it using the Unlock code...Get the Unlock code from here Unlock-free.com and Unlock it .Then use with any GSM Network Sim card in the phone...It asks for security unlock code..You can get the Free master reset code for Nokia DCT phones and ALCATEL phones reset it ....
