EC25J Module CDMA Config

Hi,
we are using EC25 E module in India for data uploading in cloud, it is working fine and we changed the module to EC25J and checked the data uploading using Indian sim card it is working fine, when we are using EC25J module in japan with Japan sim its not working, Can anyone help me to make it work or any changes that required to change for the CDMA carriers
Thanks in advance

Hi Revathi
What is your current software version? Probably because your software version is too old, I will send you the latest version by mail.
