How is the M4 Mini tested in Germany?

Every Mine Media M4 Mini is carefully checked according to a test protocol in Germany before it is sent to the customer. Among other things, all four SIM card slots are checked, the speed of the WLAN is tested and the firmware is updated to the latest version. Only when the device meets all the points of the protocol is it sent to the customer. A copy of the test report is transparently enclosed with each device before shipment.
