5G lets you do more, faster. It's better for streaming. Better for online gaming. And better all round. We've sought out the very best 5G SIM only deals right here.
What are 5G SIMs?
In most cases, a 5G SIM is a physical SIM card that you insert in your phone and which gets you a 5G mobile internet connection.
All you have to do is put it in a 5G-compatible smartphone and you’re good to go, with 5G speeds that are up to 20 times faster than 4G.
5G SIMs are also available as e-SIMs. With 5G e-SIMs, there’s no physical SIM card that you have to insert. Instead an eSIM is a small chip that comes embedded in your handset when you buy it.

Will my current SIM support 5G?
Your current SIM is compatible with 5G, since all SIMs are compatible with 3G, 4G and 5G.
To get 5G, you’ll need to sign up for a 5G SIM only plan from your provider and use it with a 5G-compatible phone.
How do I know if I have 5G in my area?
The best way to find out if you can get 5G is to use networks’ 5G availability checkers.
- O2 5G postcode checker.
- Three 5G postcode checker.
- Vodafone 5G postcode checker.
- EE 5G postcode checker.
- BT 5G postcode checker.
- Sky Mobile 5G postcode checker.
- Tesco Mobile 5G postcode checker.
- VOXI 5G postcode checker.
Which network's best for 5G? Take a look at our guide where we've put them to the test.
Is 5G available in the UK?
You can get 5G in the UK, but availability is still largely restricted to towns and cities. In the event that you buy a 5G SIM and you’re in a location where 5G is not available, you’ll be connected via 4G.
Will a 5G SIM card work in a 4G phone?
Yes. But the service you’ll get will only be 4G. If you want to enjoy 5G, you’ll need a 5G-compatible smartphone.
Are 5G SIMs more expensive than 4G?
You might assume they would be. But in fact, when you buy a 5G SIM only deal from Three, Vodafone, O2 and Sky, you’ll pay no more than you would do for a 4G service with the same data allowance.
However, EE is the exception among household-name networks and charges more for 5G SIMs.
Is there a 5G iPhone?
At the time of writing, the sole iPhones that support 5G SIMs are:
What happens when I'm not in a 5G area?
When you leave a location covered by 5G, you’ll automatically and seamlessly be transferred to 4G. Conversely, when you return to a 5G area you’ll automatically transition to a 5G service.
What’s the cheapest 5G SIM deal?
Shop around and you can get a 5G SIM deal for not much more than £5 per month. Three and O2, in particular, offer a range of 5G SIMs around this price point.
Sky Mobile also offers 5G SIMs from £5 per month. But in order to get the deal for that price, you’ll need to be a member of its free-to-join Sky VIP customer loyalty scheme.
Can I get a 5G SIM card with unlimited data?
Yes, you can. EE, giffgaff, O2, Tesco Mobile, Three, Vodafone and VOXI all offer 5G deals with unlimited data.
Expect to pay a shade under £20 per month.
