Three has killed data fees for certain streaming services. That means you can watch Netflix and TVPlayer to your heart's content on your phone using your data connection, without racking up a big bill.
The new tariffs are called Go Binge, as they save you money when you're binge-watching on the go.
As well as Netflix and TVPlayer, they also work with the music streaming services Deezer and SoundCloud.
To qualify, you'll need an Advanced plan with at least a 4GB data allowance. These start at £12 a month.
However, existing customers will have to switch to a higher price plan to qualify. So even if you're already on the Advanced £12-a-month plan, you'll have to upgrade – the next cheapest option is £15 a month.
The deals are live from today.
Three hopes that these tariffs will free up people to use their phones more.
"It's my ambition to unlock any restrictions that stop consumers from enjoying their mobiles and using them to do the things they love," Dave Dyson, Three's chief executive, said in a statement.
"With Go Binge, we are the first network in the UK to give people the freedom to use their data to stream their favourite shows and music without any boundaries and without worrying about restrictive data allowances and charges."
So what will you watch first? 'Glow'? Or 'Stranger Things'?
