Well, don’t do like I did and ordered what would arrive first versus the better product with a longer shipping time!
I originally wanted the EM7565 however it wasnt showing being able to deliver to me until the end of the month. So i ordered the lower cost and model EM7455 which arrived overnight.
The same with the M.2 to mini PCI-E adapter without the SIM slot.
I ended up getting one with two sim slots.
Come to find out, you need a mini PCI-E to USB Adapter just to properly prepare one of the LTE modules for the device that will be using it. Particularly if you plan to use an LTE Model for a laptop on a Router Board like the Banana Pi R3.
