Hello, it is correct to use ATD command to make phone calls. Please use the latest version of EM06-E to test. At the same time, you can insert the current SIM card into the mobile phone to dial 91 to verify whether the call can be made.
For 4G calling VOLTE support is required but checking ims config shows volte disabled for our carrier AT+QCFG=“ims”
also checked supported carrier list using command AT+qmbncfg=“list” and our network operator is not listed.
How to proceed further? is there any ims configuration file to enable volte support for our network operator?
