LTE Extender Gen3 Band Support

Seems I’ll be moving to VZW’s Gen3 LTE Extender, ASK-SFE116 as the older units have been retired.

Searching online, I expect that the ASK-SFE116 ships on Band 13. Which bands do the new units support? Can the new extenders be configured to support Band 4?

I previously had a Gen2 SLS-BU10B that was recently discontinued by Verizon. After many support calls, VZW Support remotely changed the Gen2 from Band 13 to Band 4. Do the new units support the same functionality?
