Where can I find the ESN (Electronic Serial Number) of my Qualcomm phone or modem?

Answer:  You can view the ESN in the following ways

1. Via Label:  The ESN is printed on a label on the phone or modem, in both hex and decimal formats.
2. Via Menu:  Via the on-screen menus of the GSP-1700 and GSP-1600 handheld phones
3. Via AT Command:  In addition, it is possible to read the internal ESN from the data port of the phone using the AT+GSN command.  The AT+GSN command will return the hexadecimal version of the ESN.
