We see a lot SIM only deals at T3 as we're constantly hunting out the very best SIMO packages. That's because we love the large quantities of data, minutes and texts they deliver for very little money when compared to with-handset offers.
Right now, many people are using very little of their data packages. As working from home has increased following the global health crisis, WiFi is being used much more than mobile data, meaning your current provider is taking you for a ride and charging you for a service you're not using.
