Enable/Disable IMS

How do I Enable or Disable IMS on EM7455?

Can I use “IMS Test Mode” command AT!IMSTESTMODE for this?

AT!IMSTESTMODE=1 will enable IMS test mode and AT!IMSTESTMODE=0 will disable IMS test mode. You will need to unlock the level 2 AT command first in order to access the !IMSTESTMODE command.

Thanks for your reply. Will it disable IMS service as well?

Not sure what you really mean by “disable IMS service” as that is not up to the module since IMS service is provided by Verizon.

By enabling IMS test mode, module should be able to attach to the network without registering to IMS service so in that sense, you can deem IMS service as “disabled” from the module side.
