SIM card will not activate in Mesa 3 Windows
16 Jun 2020
Mesa 3 Windows model units must have OS release 20043 or higher installed to be able to activate a new inserted Micro SIM card (after purchasing a compatible 4G LTE cellular data plan). If needed, this is available to download from the following web page. Installing this patch will uninstall older cellular modem drivers then install newer drivers.
Inserting a Nano SIM card adapter may damage the Micro SIM card slot header pins. If this has occurred, the unit will need to be submitted to a certified repair center.
