What happens next. Customers: download the app and enter your shop's key — or the free key MPCD-FREE-MONTH — with this mobile number, then verify your email or WhatsApp in the app for a free month. Shops: we confirm your details and switch your shop on; from then on your installers verify their own number on each customer's PC and the PC shows your logo and their contact. Installers: once approved, choose "I am a registered engineer" in the app on the customer's PC.
