Prepaid plan connection drops after 4 hours

Hi,

I have a WE826-Q with a Quectel EM12-G, running GoldenOrb_2021.

When using a prepaid plan/sim, my internet connection seems to drop right at 4 hours of uptime. Rebooting the router/modem restores connection.

I have prepaid plans/sims for two different local service providers. These are Docomo Pacific and IT&E out here in the Guam area.
I also have a regular postpaid plan/sim for IT&E.

When I am using the regular postpaid sim, the connection is great and never drops.

When I use either of the postpaid sims, the connection is great until 4 hours of uptime. Then the connection monitor shows DOWN and I have no internet, despite still showing proper provider, signal…etc.

This is despite the signal strength being over 85%.

Any help or suggestions are greatly appreciated!
