ATT 3g radio worked -now it doesnt

thanks,
is new IMEI number Same as serial # when looking at it on 2GIG CG2?

figured out that it is the same

Yes, the module number can also be found on the module itself, followed by IMEI:

The Secure Message has been received and the module swap has been processed. You will need to run a cell test at the panel to resume communication. Once a successful cell test has been run, please wait about 20 minutes for all connection commands to complete and the swap process to finalize.

Thanks for all the help from all of you!
