Did you know you can easily see how much data you are using, and more importantly what apps are eating up your data?  Head to Settings, then Mobile Data.  As you scroll down, it will show you not only how much data you have used and then how much each app has used in order.  Netflix, social media, photos, Safari and Chrome, personal hotspots and even Zoom are all big consumers of data.  Sometimes customers underestimate how much data they use (a little bit like how we underestimate the amount we eat and drink over Christmas), or suddenly go over a data allowance because children have watched a film on their phones.  This is an easy way to keep track of your data usage.  Unlimited data tariffs can be extremely reasonable.
