Absolutely none of the MDM products on the market allow for the reading of personal e-mail, SMS, phone records, etc.

So you’re not aware of Sophos’s MDM offering? That explicitly states they can make copies of all SMS messages?

How about call logs, with SureMDM?

Also I said nothing about personal emails.

Moreover, the “wipe” of data is the removal of company data. It doesn’t wipe your phone, it just removes the work profile (Android) or deprovisions the work profile and associated apps (Apple). All of your non-work-related data is untouched.

No, the ‘wipe’ can be a full factory reset.
