Hello,
Im trying to enable volte support in ec25-e.
Here is the device details:
ATI
Quectel
EC25
Revision: EC25EFAR06A17M4G
AT+QGMR
EC25EFAR06A17M4G_20.200.20.200
But qcfg commands result in error:
at+qcfg=“ims”
ERROR
Im able to establish data networks. But Im trying to connect volte so than I can send/receive SMS.
The service provider is Jio and the country is India.
Please suggest / guide me with the steps for enabling VoLTE.
Hi @selvakn
It looks like a notation problem, you can use AT+QCFG=? Do you check whether the ims command exists?
Please find the response:

@lyman-Q :
You are right, after trying with minicom, able to execute.
AT+QCFG="ims"
+QCFG: "ims",1,1
Was able to enable volte after
at+qmbncfg="deactivate"
AT+CFUN=1,1
Thanks!
