With the increase in download speed, it could feel like more data is being consumed. However, that is NOT true. If a file requires 1GB of data to download on 4G, it will use the same 1GB of data to download it on 5G. It just downloads faster!
With Digi 5G, your quota consumption may increase depending on your usage and type of content. With streaming apps for example, you may consume higher internet quota due to better resolution. e.g. Video streaming on the same video in 4K could take up to 4x more data compared to a Full HD@1080p version.
