We use the Gigacube H112-370 with Vodafone for a small business, so I thought I'd share my experiences.
I run speedtest and graph it with Nagios - see attached graph.
You can see a cycle of good speeds at night and poorer speeds during the day.
When 5G is running well we get good speeds - up to 400mbs download and 75mbs upload.
Approx once a day it slips back into 4G so speed is e.g. maximum 60mbs download and 23mbs upload. However it can be worse and barely working with 4mbs download and 1mbs upload.
I find a soft reboot from the GUI will usually fix this.

I have spoken to Vodafone tech support for Gigacube.
They say the router should resync with a server every 2 hours to keep 5G up. If not the connection reverts to 4G.
They recommend the following to resolve it:
Power off the router, remove and reseat the SIM, then power on.
This "resets the 5G sync"
This does actually work but is a bit of a pain, especially if working remotely due to the pandemic...
Can't get anything more than this from Vodafone, e.g. why it works or if there is going to be an upgrade to the firmware...
If anyone can find a way of scheduling a reboot on the router each day, please let me know.
