I agree with R. Harris but from the operator point of view there are tangible benefits with Advanced Device Management or MDM when it comes to domestic users.
For example if I am carrying a Nokia phone and I am having difficulties with MMS or any other service I have to know which Nokia device I am carrying.
If I do not remember, I need to remove the battery from the phone and check from the sticker inside which model I have and then call the operator again.
That was just one example but if the operator would have for example an icon in the phone "Help Desk" or something similar the software could upload all the current information of the phone, configurations and software to the operator server prior the call.
This "remote diagnostics" procedure would reduce the troubleshooting time dramatically and also when the operator could configure the phone remotely that would guarantee better results than sending SMS messages today to the user.
Also application management is something that could bring lot of benefits to the operators.
