Soft lock on dual sim phones at vodacom

Why block the capability of dual sim phones? Other service providers dont block the P10 and other phones. I need to keep my existing business contract with vodacom and also want to have a personal contact with Vodacom in the same phone. This will come in handy for travelling internationally and not wanting to have two phones and a tablet with me.

Need to know how to make the 2nd sim work in the phone otherwise the phone is not according to the manufacturer specification and soft locked with service provider software limitations. This is a massive limitation to device and also clouding my selection on devices and service providers that are offering such functionality.
