5G is here. The next generation of smartphone technology is well into its rollout, with a huge range of exciting 5G smartphones already available. But to use a 5G phone, you’ll need to be on a 5G data plan. There are plenty of monthly 5G plans to pick from. But if you’ve already got a 5G smartphone, you can pick up a 5G SIM only plan instead. 

What are 5G SIMs?

A 5G SIM card does what it says on the tin - it’s a SIM card that will enable you to connect to 5G, the latest advancement in mobile phone technology. It’s a step up from 4G, and that means it’s considerably faster. It has a big impact on internet speeds, downloads, gaming, and streaming. 

To connect to 5G, you need a 5G ready phone, a 5G SIM card and you must live in an area with 5G availability. 

If you have a 5G smartphone already, or are about to buy one, then you can get on 5G with a SIM only deal, with many networks currently offering a range of 5G SIM only deals. 

Can I get a 5G SIM only deal?

You can get a 5G SIM only deal on all the major networks here at Uswitch.

Take a look at our SIM only comparison tables and find the ideal 5G SIM only deal, with the right amount of data, on the network you want to sign up with, at a price that suits you. 

What’s the cheapest 5G SIM deal?

There are a range of cheap 5G SIM only deals to choose from.

One thing to remember is, if you do use 5G to stream and download, you might end up using a lot of data quite quickly. So it is worth looking out for a deal that has enough data to suit your needs.

Can I get a 5G SIM card with unlimited data?

One way of making sure you never run out of data on 5G is by getting a deal that offers unlimited data, and thankfully there are unlimited 5G data deals from the likes of Vodafone, Three and more.

Yes, a 5G SIM card will work in a 4G phone, but it won't connect you to 5G.

You’ll still be able to use your phone as normal on 4G, but to get access to 5G, you’ll need to pop the 5G SIM into a 5G smartphone, like the iPhone 12 or the Samsung Galaxy S21.

Not necessarily. Some networks, such as Three, are offering 5G with their SIM only deals as standard with no extra cost. So all you need to connect is to pair the SIM card with a 5G phone.

If you have a 5G SIM and you go into an area that doesn’t have 5G, you’ll simply drop down to 4G. 

If you live in an area that is not currently switched on to 5G and you want to connect, you’ll have to wait until a network makes 5G available in your area.
