Quick Net data SIM, old system, billed 184 monthly.
It has a fair usage of 20 GB per day, which renews every day at 10 AM. If you consume your daily limit, the internet will continue but at a reduced speed until it renews the next day.
I have been using the SIM for 5 years with a 5G modem, and the speed is amazing.
Whether you want to take it with the modem or without, the choice is yours.
