Three mobile has for a long time been well known in the UK for offering good deals, especially for customers looking for some seriously big data bundles. In the early days, the network was blighted by poor reception in many areas but these days Three mobile doesn't have any such issues and its prices can be stellar.
So take a look at our comparison tool to see what you can get for your money with Three. And below that we've also handpicked the best the network has to offer on flagship handsets such as the iPhone XR and Samsung Galaxy S10.
And if you're perfectly happy with your current handset but are at the end of your contract, then we heartily recommend that you consider the 100GB Three SIM only deal for £20 per month

OK, so the Samsung Galaxy S9 doesn't make massive strides on the S8, but that doesn't mean it's not still one of the premier Android phones on the market. The cameras in particular are awe inspiring and tangible improvements have been made to the biometrics and position of the fingerprint scanner.

Oh gosh, Apple went and did it. After years upon years of incremental upgrades, it finally made something special to celebrate the 10th anniversary of the iPhone. For the iPhone X it has dropped the bezel altogether, while the 5.8-inch Super Retina HD is scarily good – and then it tweaked things a year later for the XS. Marvellous!
Samsung has now well and truly put the flaming memory of the Note 7 behind it. If the Note 8 was exceptional (6.3-inch infinity display and 6GB RAM), then the Samsung Galaxy Note 9 is even bigger and better (6.4-inch infinity display and 8GB RAM). If you want the best big screen Android phones on the market, then look no further.
Thanks to the spectacle that was the iPhone X launch, the reception for the iPhone 8 was a little bit flat. Perhaps unfairly – it improves on the iPhone 7 with wireless charging and an improved camera. Plus, it's quite a bit cheaper. So if you're looking for the best iPhone but balk at the iPhone X expense, try the 8 on for size instead.

There's no doubt that the Samsung Galaxy S8 is a fantastic phone. The lightning fast chip-set and abandonment of a large bezel around the screen makes it the premier Android experience. And now that the S9 is here, it's no longer even that expensive.

What are the benefits of Three?
The benefits of getting a Three mobile deal can be split into three main categories:
Another factor that has made Three so popular is its offer off massive amounts of data (or even unlimited) at some brilliant price points.
Can I keep my number when I switch to Three?
You sure can, if you switch over to an Three mobile deal and want to keep your old number, then simply call your old network, get a PAC code and transition it over.
If you were previously on Three, you can still keep your number but it is slightly more complicated. They won't let you keep your number, so you have to use this workaround. Buy a free pay-as-you-go SIM from any other network and tell your network that you're moving.
They'll release the PAC code, which you then give to the substitute network. Then, you immediately get another PAC code from them. Take that to your old network, and they'll move your number to your new contract. Long winded, but easier than learning a new number!
Can I use my Three phone abroad?
When it comes to roaming abroad Three mobile deals are a pretty great way to go. With access to free roaming anywhere in Europe and options in at least 71 countries, Three trumps the rest for roaming charges.
There are select countries where you will have to pay extra to use your data, you can check Three's website to find these countries.
