@rstoleru There are a few different modem options, you can see in the dropdown on this page: https://www.modalai.com/collections/voxl-add-ons/products/voxl-lte?variant=32449203601459
Most NA folks order the WP 7610 while EU folks order the 7607.
The supported bands vary but you can look up the datasheets from Sierra Wireless for more info.
You can enable / disable certain bands via. AT commands, in NA for example, we legally have to disable band 5 for civilian drone flight.
