SKY
For the vast majority of people in the UK, Sky are known as one of the top providers of TV and Broadband services, but it's worth remembering that the firm are also one of the best new providers of mobile services in the country.
Don't worry if you didn't know about Sky's mobile service because it's still pretty new, having only launched last January and promising to shake-up the industry with some bold new features.
The flagship service, which you might have seen mentioned on countless Tom Hardy TV adverts, is the ability for users to rollover their mobile data and keep it for up to three years.
So rather than having a flat amount each month, customers have a sort of virtual piggybank, where leftover data is popped into at the end of each month.
Then when you use more than your standard tariff, you can just dip into your piggybank.
So no more running out of data and paying over the top for a measly 1GB upgrade.
One year on and the feature is clearly working its magic, saving UK customers plenty of money on their phone bill because this week Sky announced that their customers have saved over £20 million worth of mobile data since launching in January last year.

“When we entered the smartphone market we wanted to tackle the issue of unused data and customers paying too much for their allowance,” said Liz Wynn, Commercial Director for Sky Mobile.
“Over 20 million people in the UK were regularly buying more data than they needed to avoid going over their data allowance and accepted this as the norm.
“We created Sky Mobile and Roll to challenge this status quo. One year on we can see its working, with our customers already saving £20 million worth of data.”
Sky also revealed that the average UK smartphone user wastes almost half of their mobile data they buy every month - costing an estimated £2 billion each year.
However, for those who do occasionally go over, the pain of paying mobile networks as much as £5 for just 1GB of extra data is well known.
As such, it's always worth checking how much data you are using each month to make sure your contract is suitable. Who knows, maybe you could save a bundle by switching to Sky Mobile?
This isn't the only good news for Sky customers though, as Sky TV services in 2018 could be set for a major new feature coming later this year.
Recently Sky announced their intention for customers to access its TV and streaming services without installing a dish on their properties.
This means subscribers to Sky's various services will be able to enjoy a massive amount of TV and film content without a satellite dish - something many telly fans can't due to renting restrictions or architectural limitations.
It's believed that SKY would also plan to deliver content via its broadband services, rather than satellite communication.
The company has not announced a specific date for this major upgrade, though it is thought to be due to launch at some point during 2018.
Equally, there's no information yet on how this might impact existing prices, or what sort of broadband speeds customers could achieve.
The only thing we do know, according to Sky chief executive Jeremy Darroch, is that this new no dish update would allow Sky to provide services to an extra 6 million households throughout Europe - 2 million of which are located in the UK.
