How does the e-SIM work on EC25-J?

Dear Experts

How does the e-SIM work on EC25?
How can I download and set it up?
I’d like to know the big flow for using e-SIM.
APN is KDDI.

Thank you.

Dear Ihuijae,
Thanks for your inquiry in Quectel forum.
If you want to test eSIM function, please note that you should contact the local operator and confirm whether they can support it and debug with them. For our module, you just need to enable AUTO BIP with the following aommand. Please check it. Thanks!
For Qualcomm platform, AUTO BIP is supported by default, our Quectel only add the following feature :
If need, please set PDP authentication type to an appropriate type
AT+QCFG=“bip/auth”, to set PDP authentication type
= 0 means No PDP authentication
= 1 means using PAP as PDP authentication type
= 2 means using CHAP as PDP authentication type
The default value of is 0. And the new setting will be written in NV flash.
If the default setting works fail (ex: PDP activate failure), you can try to set PDP authentication type to an appropriate type: PAP/CHAP depend on network design.
