Anyone know if it’s possible to upgrade the Ed25-af mini PCIe card to a 5g card? Looks like quectel makes 5g cards now. Do you think if I bought one it would work out of the box? Not sure which one to get that works with T-Mobile and Att in USA.
NO.
Physically you need a adapter from PCIe to M2.
Then you also need to add software driver.
